I have been asked to update my question so here goes:
I have records in a database, some of which have wave file names attached. I am looping through the database and wanting to write out the word "Play" in a column under a header named Audio File. When "Play" is clicked on, the audio player plays the file and turns the href word to "Pause". When my code loops through these records, it is assigning a separate ID to each href. For me to call the function that starts the audio player, I need to send an audioControl ID (aControl) variable as well as the src source file (thissource) variable for the audio player - hence the & and " in the function call. When I use the onclick event in a button, it triggers the function. However, when I click the href link (which is what I want instead of a button) nothing happens. I am not sure which part of the code is messy, as I found the function code on the internet. Thank-you in advance for any and all help.
No matter what I do, my href onclick will not trigger a javascript function. I have taken the return false out of the function and put it in the href but that doesn't work either. I have put the same onclick code in a button and it triggers great.
HTML:
<a href='#' onclick='passvariables(" & aControl & "," & thissource & ");'>Play</a>
Javascript:
function passvariables(aControl, thissource)
{
var yourAudio= new Audio();
yourAudio.src = thissource;
yourAudio.type = 'audio/wav';
ctrl = document.getElementById(aControl);
ctrl.onclick = function ()
{
// Update the Button
var pause = ctrl.innerHTML === 'Pause';
ctrl.innerHTML = pause ? 'Play' : 'Pause';
// Update the Audio
var method = pause ? 'pause' : 'play';
yourAudio[method]();
// Prevent Default Action
return false;
}
}
Just have onclick call passvariables without the return and have passvariables return false.
You can try:
window.passvariables = function(aControl, thissource) {
// Your code
};
My guess if that your function is defined within another function (executed onload for instance). Hence "passvariables" is not defined in the "window" scope.
I saw you updated your questions that's good :)
First I recommend you to use the javascript library jquery which is easier to manipulate the DOM and you can easily find ressources and help on this site.
Here's what your code should look. I haven't tested it but it's a good overview of what this should be.
Put this in the <head> section of your HTML code
<script src="http://code.jquery.com/jquery-1.12.0.min.js"></script>
<script>
$(document).ready(function() {
//Assigning onClick function for every HTML tags having the css class "Play"
$('.Play').click(function(){
if($(this).html() == "Play"){
//retrieving information about the audio
var waveFile = $(this).attr("data-waveFile");
var audioId = $(this).attr("data-audioId");
//calling the startAudio function and assign the Audio object to myAudioObject
var myAudioObject = startAudio(waveFile, audioId);
if(myAudioObject){
//Audio started playing
$(this).html("Pause");
}else{
alert("error while starting to play file");
}
}else{
var isPaused = pauseAudio(myAudioObject);
if(isPaused){
//The pauseAudio function returned true so the audio is paused
$(this).html("Play");
}else{
alert("error while pausing");
}
}
});
//Functions to manage audio Player
function startAudio(waveFile, audioId){
audioObject = document.getElementById("audio");
audioObject.src = waveFile;
audioObject.play();
return true;
}
function pauseAudio(){
//do whatever to pause
audioObject = document.getElementById("audio");
audioObject.pause();
return true;
}
});
</script>
in the <body> section of your HTML code where you construct the table using database datas :
<table>
<tr>
<td>Song name</td>
<td>Action</td>
</tr>
<tr>
<td><%=WaveFile%></td>
<td>Play</td>
</tr>
</table>
<audio id="audio"></audio>
Note the <%=WaveFile%> and <%=AudioId%> should be the values you get from the database in your loop
Thank-you everyone for your help! I finally got it working! Here is the code:
yAudio = "'yourAudio" & thisline & "'"
aControl = "'audioControl" & thisline & "'"
thissource = "'/WaveFiles/" & RS.Fields("AudioIssues") &"'"
R"<td width=12 class=allprint>Play</td>"
// Call and play audio via JavaScript
$(document).ready(function()
{
var aElement = document.createElement('audio');
$('.Play').click(function()
{
if($(this).html() == "Play")
{
var waveFile = $(this).attr("data-waveFile");
var audioID = $(this).attr("data-audioId");
aElement.setAttribute('src', waveFile);
aElement.load()
aElement.addEventListener("load", function()
{
aElement.play();
$(this).html("Stop");
$(".duration span").html(aElement.duration);
$(".filename span").html(aElement.src);
}, true);
aElement.play();
$(this).html("Stop");
}
else
{
var waveFile = $(this).attr("data-waveFile");
var audioID = $(this).attr("data-audioId");
aElement.setAttribute('src', waveFile);
aElement.pause();
$(this).html("Play");
}
});
});
I have created a fiddle of my function here( http://jsfiddle.net/rhy5K/10/ ) . Now i want to provide the Sound "Mute/unpute" option for users. Example if i click on "a link then sound playing like Get ready,5,4,3,2,1 should be mute and vice-versa.
I am thinking like to call a to toggle_sound function on click, but i am confuse like what should i write inside the function to mute the sound.
Please provide me a logic, or a solution for my problem.
Explanation using code example:
I want to MUTE/UnMUTE this below sound playing
var playGetReady = function (done) {
var ids = ['audiosource', 'a_5', 'a_4', 'a_3', 'a_2', 'a_1'],
playNext = function () {
var id = ids.shift();
document.getElementById(id).play();
if (ids.length) {
setTimeout(playNext, 1000);
} else {
done();
}
};
playNext();
};
Warning: This JS fiddle demo may play sound on load
Try
HTML5 Video_tag for display video with audio
or
this below example along with html5 with jquery
window.my_mute = false;
$('#my_mute_button').bind('click', function(){
$('audio,video').each(function(){
if (!my_mute ) {
if( !$(this).paused ) {
$(this).data('muted',true); //Store elements muted by the button.
$(this).pause(); // or .muted=true to keep playing muted
}
} else {
if( $(this).data('muted') ) {
$(this).data('muted',false);
$(this).play(); // or .muted=false
}
}
});
my_mute = !my_mute;
});
I think you can use:
document.getElementById(id).volume = 1;
or
document.getElementById(id).volume = 0;
I have this audio tag playing in the background, and I'm able to store the progress in seconds to a cookie.
But in no way I'm able to start the audio from that cookie. (for continuing on other pages)
$("p#sound audio").currentTime = $.cookie("audioTime");
<audio autoplay="autoplay" loop="loop" ontimeupdate="document.getElementById('tracktime').innerHTML = Math.floor(this.currentTime); $.cookie('audioTime', Math.floor(this.currentTime));">
<source src="audio/song.ogg" type="audio/ogg" />
<source src="audio/song.mp3" type="audio/mp3" />
Your browser does not support the audio tag.
</audio>
<span id="tracktime">0</span>
Does this have to do with the song being loaded again from start?
Thanks!
EDIT:
$("p#sound audio").get[0].currentTime
With .get[0], it doesn't work either.
Can someone please clear things up for me? Greatly appreciated!
You need to wait until audio source loads before you set the current time.
$(function(){
$('audio').bind('canplay', function(){
$(this)[0].currentTime = $.cookie('audioTime');
});
});
You can set the start time by adding t=<time> to the URL, as documented here: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_HTML5_audio_and_video#Specifying_playback_range
E.g. <audio src="http://example.com/audio.mp3#t=50></audio>
At first there is an error in your code because currentTime is not a part of jQuery (but you already know this)
$("p#sound audio").currentTime // is incorrect (refers to a property of jQuery)
$("p#sound audio")[0].currentTime // is correct (refers to a property of DOM element)
I discover that the audio tag has some strange things and can be operate differently from browser to browser, for example in Chrome.
At first you have to wait for the 'durationchange' event to be sure the length is known by the object.
After this you have to start the stream with 'play()' (if not already started) and pause it (sometimes after a short delay) with the 'pause()' function. Then you can change the 'currentTime' property with the value. After this you have to start the stream again by using the 'play()' function.
Also it is sometimes needed to load the stream by yourself by using the 'load()' function.
Something like this:
$(document).ready( function()
{
var a = $('audio:first'),
o = a[0];
a.on( 'durationchange', function(e)
{
var o = e.target;
if( o )
{
o.pause();
o.currentTime = parseInt( $.cookie("audioTime"));
o.play();
}
});
if( o )
{
o.load();
o.play();
}
});
You have to play with it to be sure what is the best in your situation, for example the resume (play again) method to delay it for a second or so.
When using this method you don't have to use the autoplay feature because most of the time it doesn't work.
Hope it helps, greetz,

what I found in my case is that there is an issue with context somewhere. I initialize audio under the window context but when I try to change currentTime from XMLHttpRequest response it does NOT work. I don't know the answer yet but I'm providing a clue maybe an expert in Javascript will know how to make it work.
/* initialize this.audio player */
Audio = function() {
var that = this;
// keep track of playback status
var AudioStatus = {
isPlaying : false
};
// define references to this.audio, pulldown menu, play-button, slider and time display
that.audio = document.querySelector("AUDIO");
/* load track by menu-index */
var loadTrack = function() {
if(that.audio == null){
log("audio null"); return;
}
that.audio.src = '../sounds/400.mp3';
that.audio.load();
};
/* callback to play or pause */
that._play = function() {
if(that.audio == null){
log("audio null"); return;
}
that.audio.play();
AudioStatus.isPlaying = true;
};
that._pause = function() {
if(that.audio == null){
log("audio null"); return;
}
that.audio.pause();
AudioStatus.isPlaying = false;
};
that.playPause = function() {
if (that.audio.paused) {
self._play();
}
else {
self._pause();
}
};
/* callback to set or update playback position */
that.updateProgress = function(value) {
if(that.audio == null){
log("audio null"); return;
}
that.audio.currentTime = value; // <<<--- it does NOT work if I call from XMLHttpRequest response but it DOES if it is called from a timer expired call back
};
that.isAudioPlaying = function(){
return AudioStatus.isPlaying;
};
};
This works for me.
if (!isNaN(audio.duration)) {
audio.currentTime = 0;
}
Hope it helps!
This solved it for me:
$("p#sound audio").on('loadedmetadata', () => {
$("p#sound audio").get(0).load();
});
So I could later set the currentTime without worrying about whether the audio was loaded or not.
I had a similar problem when trying to play a HLS stream through an HTML audio element.
No matter where and how I tried to set the currentTime property on the audio element, it wouldn't work until about 2.5s after calling audioElement.play().
//Calling this
htmlElement.currentTime = 5.5;
console.log('currentTime: '+htmlElement.currentTime);
//Would return 'currentTime: 0';
What did work tho, was if I called that in a timeout with 2500-3000ms delay.
After a day of debugging to pinpoint the element state in which it would allow me to set the currentTime property, so I wouldn't have to rely on a fixed timeout.
My solution was to listen to 3 HTMLMediaElement events (https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement#events): loadedmetadata, loadeddata and canplaythrough and setting custom flags when they were first reported.
When all 3 were reported and the HTMLMediaElement.duration property was bigger than 0, I set the HTMLMediaElement.currentTime to my desired value inside the first HTMLMediaElement timeupdate event callback.
This can be summed up in the following code snippet:
let audioElementStates = {
'metadataloaded': false,
'dataloaded': false,
'canplaythrough': false
};
let shouldSetOldTime = true;
let audioElement = document.getById('audio-element');
audioElement.src = 'https://somedomain.com/hlsplaylist.m3u8';
audioElement.addEventListener('loadedmetadata',()=>{audioElementStates.metadataloaded = true;});
audioElement.addEventListener('loadeddata',()=>{audioElementStates.dataloaded = true;});
audioElement.addEventListener('canplaythrough',()=>{audioElementStates.canplaythrough = true;});
audioElement.addEventListener('timeupdate',()=>{
if(shouldSetOldTime &&
audioElement.duration>0 &&
audioElementStates.metadataloaded &&
audioElementStates.dataloaded &&
audioElementStates.canplaythrough){
audioElement.currentTime = 5.5;
shouldSetOldTime=false;
}
});
audioElement.play();
For reference I was using this with Vue.js in a Quasar framework mobile app packaged with Apache Cordova.
NOTE: The loadedmetadata check can probably be skipped, since loadeddata would presumably never fire before loadedmetadata.
I understand that it is not possible to tell what the user is doing inside an iframe if it is cross domain. What I would like to do is track if the user clicked at all in the iframe. I imagine a scenario where there is an invisible div on top of the iframe and the the div will just then pass the click event to the iframe.
Is something like this possible? If it is, then how would I go about it? The iframes are ads, so I have no control over the tags that are used.
This is certainly possible. This works in Chrome, Firefox, and IE 11 (and probably others).
const message = document.getElementById("message");
// main document must be focused in order for window blur to fire when the iframe is interacted with.
// There's still an issue that if user interacts outside of the page and then click iframe first without clicking page, the following logic won't run. But since the OP is only concerned about first click this shouldn't be a problem.
window.focus()
window.addEventListener("blur", () => {
setTimeout(() => {
if (document.activeElement.tagName === "IFRAME") {
message.textContent = "clicked " + Date.now();
console.log("clicked");
}
});
}, { once: true });
<div id="message"></div>
<iframe width="50%" height="300" src="//example.com"></iframe>
Caveat: This only detects the first click. As I understand, that is all you want.
This is small solution that works in all browsers even IE8:
var monitor = setInterval(function(){
var elem = document.activeElement;
if(elem && elem.tagName == 'IFRAME'){
clearInterval(monitor);
alert('clicked!');
}
}, 100);
You can test it here: http://jsfiddle.net/oqjgzsm0/
Based on Mohammed Radwan's answer I came up with the following jQuery solution. Basically what it does is keep track of what iFrame people are hovering. Then if the window blurs that most likely means the user clicked the iframe banner.
the iframe should be put in a div with an id, to make sure you know which iframe the user clicked on:
<div class='banner' bannerid='yyy'>
<iframe src='http://somedomain.com/whatever.html'></iframe>
<div>
so:
$(document).ready( function() {
var overiFrame = -1;
$('iframe').hover( function() {
overiFrame = $(this).closest('.banner').attr('bannerid');
}, function() {
overiFrame = -1
});
...
this keeps overiFrame at -1 when no iFrames are hovered, or the 'bannerid' set in the wrapping div when an iframe is hovered. All you have to do is check if 'overiFrame' is set when the window blurs, like so:
...
$(window).blur( function() {
if( overiFrame != -1 )
$.post('log.php', {id:overiFrame}); /* example, do your stats here */
});
});
Very elegant solution with a minor downside: if a user presses ALT-F4 when hovering the mouse over an iFrame it will log it as a click. This only happened in FireFox though, IE, Chrome and Safari didn't register it.
Thanks again Mohammed, very useful solution!
Is something like this possible?
No. All you can do is detect the mouse going into the iframe, and potentially (though not reliably) when it comes back out (ie. trying to work out the difference between the pointer passing over the ad on its way somewhere else versus lingering on the ad).
I imagine a scenario where there is an invisible div on top of the iframe and the the div will just then pass the click event to the iframe.
Nope, there is no way to fake a click event.
By catching the mousedown you'd prevent the original click from getting to the iframe. If you could determine when the mouse button was about to be pressed you could try to get the invisible div out of the way so that the click would go through... but there is also no event that fires just before a mousedown.
You could try to guess, for example by looking to see if the pointer has come to rest, guessing a click might be about to come. But it's totally unreliable, and if you fail you've just lost yourself a click-through.
The following code will show you if the user click/hover or move out of the iframe:-

You need to replace the src in the iframe with your own link. Hope this'll help.

Just found this solution...
I tried it, I loved it..
Works for cross domain iframes for desktop and mobile!
Don't know if it is foolproof yet
window.focus();
window.addEventListener('blur',function(){
if(document.activeElement.id == 'CrossDomainiframeId'){
//do something :-)
}
});
Happy coding
You can achieve this by using the blur event on window element.
Here is a jQuery plugin for tracking click on iframes (it will fire a custom callback function when an iframe is clicked) :
https://github.com/finalclap/iframeTracker-jquery
Use it like this :
jQuery(document).ready(function($){
$('.iframe_wrap iframe').iframeTracker({
blurCallback: function(){
// Do something when iframe is clicked (like firing an XHR request)
}
});
});
see http://jsfiddle.net/Lcy797h2/ for my long winded solution that doesn't work reliably in IE
$(window).on('blur',function(e) {
if($(this).data('mouseIn') != 'yes')return;
$('iframe').filter(function(){
return $(this).data('mouseIn') == 'yes';
}).trigger('iframeclick');
});
$(window).mouseenter(function(){
$(this).data('mouseIn', 'yes');
}).mouseleave(function(){
$(this).data('mouseIn', 'no');
});
$('iframe').mouseenter(function(){
$(this).data('mouseIn', 'yes');
$(window).data('mouseIn', 'yes');
}).mouseleave(function(){
$(this).data('mouseIn', null);
});
$('iframe').on('iframeclick', function(){
console.log('Clicked inside iframe');
$('#result').text('Clicked inside iframe');
});
$(window).on('click', function(){
console.log('Clicked inside window');
$('#result').text('Clicked inside window');
}).blur(function(){
console.log('window blur');
});
$('<input type="text" style="position:absolute;opacity:0;height:0px;width:0px;"/>').appendTo(document.body).blur(function(){
$(window).trigger('blur');
}).focus();

Just make a invisible layer over the iframe that go back when click and go up when mouseleave event will be fired !!
Need jQuery
this solution don't propagate first click inside iframe!
$("#invisible_layer").on("click",function(){
alert("click");
$("#invisible_layer").css("z-index",-11);
});
$("iframe").on("mouseleave",function(){
$("#invisible_layer").css("z-index",11);
});
iframe {
width: 500px;
height: 300px;
}
#invisible_layer{
position: absolute;
background-color:trasparent;
width: 500px;
height:300px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="message"></div>
<div id="invisible_layer">
</div>
<iframe id="iframe" src="//example.com"></iframe>
This works for me on all browsers (included Firefox)

Mohammed Radwan,
Your solution is elegant. To detect iframe clicks in Firefox and IE, you can use a simple method with document.activeElement and a timer, however... I have searched all over the interwebs for a method to detect clicks on an iframe in Chrome and Safari. At the brink of giving up, I find your answer. Thank you, sir!
Some tips:
I have found your solution to be more reliable when calling the init() function directly, rather than through attachOnloadEvent(). Of course to do that, you must call init() only after the iframe html. So it would look something like:
<script>
var isOverIFrame = false;
function processMouseOut() {
isOverIFrame = false;
top.focus();
}
function processMouseOver() { isOverIFrame = true; }
function processIFrameClick() {
if(isOverIFrame) {
//was clicked
}
}
function init() {
var element = document.getElementsByTagName("iframe");
for (var i=0; i<element.length; i++) {
element[i].onmouseover = processMouseOver;
element[i].onmouseout = processMouseOut;
}
if (typeof window.attachEvent != 'undefined') {
top.attachEvent('onblur', processIFrameClick);
}
else if (typeof window.addEventListener != 'undefined') {
top.addEventListener('blur', processIFrameClick, false);
}
}
</script>
<iframe src="http://google.com"></iframe>
<script>init();</script>
You can do this to bubble events to parent document:
$('iframe').load(function() {
var eventlist = 'click dblclick \
blur focus focusin focusout \
keydown keypress keyup \
mousedown mouseenter mouseleave mousemove mouseover mouseout mouseup mousemove \
touchstart touchend touchcancel touchleave touchmove';
var iframe = $('iframe').contents().find('html');
// Bubble events to parent
iframe.on(eventlist, function(event) {
$('html').trigger(event);
});
});
Just extend the eventlist for more events.
I ran into a situation where I had to track clicks on a social media button pulled in through an iframe. A new window would be opened when the button was clicked. Here was my solution:
var iframeClick = function () {
var isOverIframe = false,
windowLostBlur = function () {
if (isOverIframe === true) {
// DO STUFF
isOverIframe = false;
}
};
jQuery(window).focus();
jQuery('#iframe').mouseenter(function(){
isOverIframe = true;
console.log(isOverIframe);
});
jQuery('#iframe').mouseleave(function(){
isOverIframe = false;
console.log(isOverIframe);
});
jQuery(window).blur(function () {
windowLostBlur();
});
};
iframeClick();
Combining above answer with ability to click again and again without clicking outside iframe.
var eventListener = window.addEventListener('blur', function() {
if (document.activeElement === document.getElementById('contentIFrame')) {
toFunction(); //function you want to call on click
setTimeout(function(){ window.focus(); }, 0);
}
window.removeEventListener('blur', eventListener );
});
This definitely works if the iframe is from the same domain as your parent site. I have not tested it for cross-domain sites.
$(window.frames['YouriFrameId']).click(function(event){ /* do something here */ });
$(window.frames['YouriFrameId']).mousedown(function(event){ /* do something here */ });
$(window.frames['YouriFrameId']).mouseup(function(event){ /* do something here */ });
Without jQuery you could try something like this, but again I have not tried this.
window.frames['YouriFrameId'].onmousedown = function() { do something here }
You can even filter your results:
$(window.frames['YouriFrameId']).mousedown(function(event){
var eventId = $(event.target).attr('id');
if (eventId == 'the-id-you-want') {
// do something
}
});
We can catch all the clicks. The idea is to reset focus on an element outside the iFrame after each click:
<input type="text" style="position:fixed;top:-1000px;left:-1000px">
<div id="message"></div>
<iframe id="iframe" src="//example.com"></iframe>
<script>
focus();
addEventListener('blur', function() {
if(document.activeElement = document.getElementById('iframe')) {
message.innerHTML += 'Clicked';
setTimeout(function () {
document.querySelector("input").focus();
message.innerHTML += ' - Reset focus,';
}, 1000);
}
});
</script>
JSFiddle
Assumptions -
Your script runs outside the iframe BUT NOT in the outermost window.top window. (For outermost window, other blur solutions are good enough)
A new page is opened replacing the current page / a new page in a new tab and control is switched to new tab.
This works for both sourceful and sourceless iframes
var ifr = document.getElementById("my-iframe");
var isMouseIn;
ifr.addEventListener('mouseenter', () => {
isMouseIn = true;
});
ifr.addEventListener('mouseleave', () => {
isMouseIn = false;
});
window.document.addEventListener("visibilitychange", () => {
if (isMouseIn && document.hidden) {
console.log("Click Recorded By Visibility Change");
}
});
window.addEventListener("beforeunload", (event) => {
if (isMouseIn) {
console.log("Click Recorded By Before Unload");
}
});
If a new tab is opened / same page unloads and the mouse pointer is within the Iframe, a click is considered
Based in the answer of Paul Draper, I created a solution that work continuously when you have Iframes that open other tab in the browser. When you return the page continue to be active to detect the click over the framework, this is a very common situation:
focus();
$(window).blur(() => {
let frame = document.activeElement;
if (document.activeElement.tagName == "IFRAME") {
// Do you action.. here frame has the iframe clicked
let frameid = frame.getAttribute('id')
let frameurl = (frame.getAttribute('src'));
}
});
document.addEventListener("visibilitychange", function () {
if (document.hidden) {
} else {
focus();
}
});
The Code is simple, the blur event detect the lost of focus when the iframe is clicked, and test if the active element is the iframe (if you have several iframe you can know who was selected) this situation is frequently when you have publicity frames.
The second event trigger a focus method when you return to the page. it is used the visibility change event.
Here is solution using suggested approaches with hover+blur and active element tricks, not any libraries, just pure js. Works fine for FF/Chrome. Mostly approache is same as #Mohammed Radwan proposed, except that I use different method proposed by #zone117x to track iframe click for FF, because window.focus is not working without addition user settings:
Makes a request to bring the window to the front. It may fail due to
user settings and the window isn't guaranteed to be frontmost before
this method returns.
Here is compound method:
function () {
const state = {};
(function (setup) {
if (typeof window.addEventListener !== 'undefined') {
window.addEventListener('load', setup, false);
} else if (typeof document.addEventListener !== 'undefined') {
document.addEventListener('load', setup, false);
} else if (typeof window.attachEvent !== 'undefined') {
window.attachEvent('onload', setup);
} else {
if (typeof window.onload === 'function') {
const oldonload = onload;
window.onload = function () {
oldonload();
setup();
};
} else {
window.onload = setup;
}
}
})(function () {
state.isOverIFrame = false;
state.firstBlur = false;
state.hasFocusAcquired = false;
findIFramesAndBindListeners();
document.body.addEventListener('click', onClick);
if (typeof window.attachEvent !== 'undefined') {
top.attachEvent('onblur', function () {
state.firstBlur = true;
state.hasFocusAcquired = false;
onIFrameClick()
});
top.attachEvent('onfocus', function () {
state.hasFocusAcquired = true;
console.log('attachEvent.focus');
});
} else if (typeof window.addEventListener !== 'undefined') {
top.addEventListener('blur', function () {
state.firstBlur = true;
state.hasFocusAcquired = false;
onIFrameClick();
}, false);
top.addEventListener('focus', function () {
state.hasFocusAcquired = true;
console.log('addEventListener.focus');
});
}
setInterval(findIFramesAndBindListeners, 500);
});
function isFF() {
return navigator.userAgent.search(/firefox/i) !== -1;
}
function isActiveElementChanged() {
const prevActiveTag = document.activeElement.tagName.toUpperCase();
document.activeElement.blur();
const currActiveTag = document.activeElement.tagName.toUpperCase();
return !prevActiveTag.includes('BODY') && currActiveTag.includes('BODY');
}
function onMouseOut() {
if (!state.firstBlur && isFF() && isActiveElementChanged()) {
console.log('firefox first click');
onClick();
} else {
document.activeElement.blur();
top.focus();
}
state.isOverIFrame = false;
console.log(`onMouseOut`);
}
function onMouseOver() {
state.isOverIFrame = true;
console.log(`onMouseOver`);
}
function onIFrameClick() {
console.log(`onIFrameClick`);
if (state.isOverIFrame) {
onClick();
}
}
function onClick() {
console.log(`onClick`);
}
function findIFramesAndBindListeners() {
return Array.from(document.getElementsByTagName('iframe'))
.forEach(function (element) {
element.onmouseover = onMouseOver;
element.onmouseout = onMouseOut;
});
}
}
A colleague and I, we have a problem similar to that of Brian Trumpsett and found this thread very helpful.
Our kiosk has animations inside iframes and we need to track the page activity to set a timer.
As suggested here, rather than tracking the clicks, we now detect the focus change at each click and change it back
The following code is Okay on macOS with Safari and Chrome but does not work with FireFox (why?):
var eventListener = window.addEventListener('blur', function() {
if (document.activeElement.classList && document.activeElement.classList[0] == 'contentiFrame') {
refresh(); //function you want to call on click
setTimeout(function(){ window.focus(); }, 1);
}
window.removeEventListener('blur', eventListener );
});
The problem is that, on Windows, it works neither with Chrome nor with FireFox and thus, our kiosk is not functional.
Do you know why it is not working ?
Do you have a solution to make it work on Windows ?
As found there : Detect Click into Iframe using JavaScript
=> We can use iframeTracker-jquery :
$('.carousel-inner .item').each(function(e) {
var item = this;
var iFrame = $(item).find('iframe');
if (iFrame.length > 0) {
iFrame.iframeTracker({
blurCallback: function(){
// Do something when iFrame is clicked (like firing an XHR request)
onItemClick.bind(item)(); // calling regular click with right context
console.log('IFrameClick => OK');
}
});
console.log('IFrameTrackingRegistred => OK');
}
})
My approach was similar to that proposed by Paul Draper above. However, it didn't work in Firefox because activeElement did not update in time for the code to execute. So we wait a little bit.
This will also fire if you tab into the iframe. For my use case, it's fine, but you could filter for that keypress.
addEventListenerOnIframe() {
window.addEventListener('blur', this.onBlur);
}
onBlur = () => {
setTimeout(() => {
let activeElement = document.activeElement;
let iframeElement = document.querySelector('iframe');
if (activeElement === iframeElement) {
//execute your code here
//we only want to listen for the first time we click into the iframe
window.removeEventListener('blur', this.onBlur);
}
}, 500);
};
I believe you can do something like:
$('iframe').contents().click(function(){function to record click here });
using jQuery to accomplish this.
