Is there a way I can use Mootools selectors to select element(s) within iframe content?
$('#myIframe input').addEvent('focus', function() {
// Do something
});
Thank you in advance!
If the iFrame is in the same domain and you are using Mootools inside it you can try:
$('myIframe').contentDocument.getElements('input').addEvent(
Example
Otherwise try this:
$('myIframe').contentDocument.querySelector('input').addEventListener(
Example
Edit:
If you want to catch the load event and then add the focus listener you could use:
var iframe = new IFrame({
src: '/RN95f/3/show',
styles: {
border: '2px solid #ccf'
},
events: {
load: function () {
alert('The iframe has finished loading.');
this.contentDocument.getElements('input').addEvent('focus', function () {
// Do something
alert('focus on input detected!');
console.log(this);
});
}
}
});
$(document.body).adopt(iframe);
Example
Sergio's answer is correct, thank you Sergio for your reply! However to get that to work, I needed to ensure iframe content was loaded before it would find input elements...
$('myIframe').onload = function() {
$('myIframe').contentDocument.getElements('input').addEvent('focus', function() {
// Do something
});
};

I'm trying to modify an iframe/object content adding a script into it. At the moment, I have something like this:
// "script" is a node with an self-called function as its content
$(function() {
$('object, iframe').each(function() {
this.addEventListener('load', function() {
this.contentDocument.getElementsByTagName('head')[0].appendChild(script.cloneNode(true));
});
});
});
And it works as expected (the script does its job and it is added to the DOM of the iframe) but the problem comes when I try to do it the "jQuery" way:
// "script" is a node with an self-called function as its content
$(function() {
$('object, iframe').each(function() {
$(this).on('load', function() {
this.contentDocument.getElementsByTagName('head')[0].appendChild(script.cloneNode(true));
});
});
});
In the previous code, the script won't be added to the dom of the iframe.
Is there any reason why the .on('load') version is not working? What can be wrong? Am I missing something?
PS: The iframe is same-origin.
In each case, the inner function's this might not always be what you want it to be. I'd try:
$(function() {
$('object, iframe').each(function () {
$(this).on('load', function (event) {
event.target.contentDocument.getElementsByTagName('head')[0].appendChild(script.cloneNode(true));
});
});
});

I've got this function:
$(document).ready(function() {
$('.post_button, .btn_favorite').click(function() {
//Fade in the Popup
$('.login_modal_message').fadeIn(500);
// Add the mask to body
$('body').append('<div class="overlay"></div>');
$('.overlay').fadeIn(300);
return false;
});
My page loads content with favourite buttons, but after Ajax call and generated additional new content the function doesn't work when you click new content's buttons. What could be not right?
That is because you are using dynamic content.
You need to change your click call to a delegated method like on
$('.post_button, .btn_favorite').on('click', function() {
or
$("body").on( "click", ".post_button, .btn_favorite", function( event ) {
Instead of this:
$('.post_button, .btn_favorite').click(function() {
do this:
$(document).on('click','.post_button, .btn_favorite', function() {
on will work with present elements and future ones that match the selector.
Cheers
class-of-element is the applied class of element. which is selector here.
$(document).on("click", ".class-of-element", function (){
alert("Success");
});
If you know the container for .post_button, .btn_favorite then use
$('#container_id').on('click', '.post_button, .btn_favorite', function () { });
so if '.post_button, .btn_favorite' are not found then it will bubble up to container_id
else if you don't know the container then delegate it to document
$(document).on('click', '.post_button, .btn_favorite', function () { });
Reference
I am not sure if I am getting your question right but you may want to try..
$.ajax({
url: "test.html"
}).done(function() {
$('.post_button, .btn_favorite').click(function() {
//Fade in the Popup
$('.login_modal_message').fadeIn(500);
// Add the mask to body
$('body').append('<div class="overlay"></div>');
$('.overlay').fadeIn(300);
return false;
});
Just try to paste your code inside done function.
Hope it helps :)
EDIT:
I also notice you are missing }); on your question.
The following worked for me
$(document).ready(function(){
$(document).bind('contextmenu', function(e) {
if( e.button == 2 && jQuery(e.target).is('img')) {
alert('These photos are copyrighted by the owner. \nAll rights reserved. \nUnauthorized use prohibited.');
return false;
}
});
});
You need to bind the jQuery click event once your ajax content is replaced old content
in AJAX success block you need to add code like here new response html content one a tag like
Click Me
So you can bind the new click event after change the content with following code
$("#new-tag").click(function(){
alert("hi");
return false;
});
When a div is opnened i want to load html content into it via ajax. This is the code im working with:
http://jsfiddle.net/uhEgG/2/
$(document).ready(function () {
$('#country').click(function () {
$("#country_slide").slideToggle();
});
$('#close').click(function (e) {
e.preventDefault();
$('#country_slide').slideToggle();
});
});
The code I think I need is this:
$.ajaxSetup ({
cache: false
});
var ajax_load = "Loading...";
var loadUrl = "www.test.com/site.html";
$("#load_basic").click(function(){
$("#country_slide").html(ajax_load).load(loadUrl);
})
How can I make it work to make it load up when the div is opened by the code above, firstly because it is setup for a click function not a toggle function, and second, because the toggle doesn't seem to be able to distinguish if the div is open or not.
to make it load up when the div is opened by the code above
$("#country_slide").slideToggle(function(){
if($(this).is(':visible')){
$("#country_slide").html(ajax_load).load(loadUrl);
}
});
Try to delegate the events.. Looks like the element is not yet available in the DOm when the event is bound
Replace
$('#country').click(function () {
with
$(staticContainer).on('click', '#country', function () {
staticContainer is the element which is already in your DOM when the event is bound and the ancestor of country
Either store the slide state in a variable or in a data attribute liek this:
<div id="country_slide" data-state="1">
And make something like this:
$('#country').click(function () {
$("#country_slide").slideToggle();
if ($("#country_slide").attr("data-state") == 0)
$("#country_slide").html(ajax_load).load(loadUrl);
});
i was trying to organize my jquery code so i created an object literal, but now the focusTextArea is not working and my textarea value is not updating.
Thanks for your help.
html
<textarea id="test"></textarea>
javascript
(function($,window,document,undefined){
var TEX = {
inputField: $("textarea#test"),
/* Init all functions */
init: function()
{
this.focusTextArea();
},
/* Function update textarea */
focusTextArea: function()
{
this.inputField.text('test');
},
}
$(document).ready(function(){
TEX.init();
});
})(jQuery,window,document);

First of all, you haven't included jQuery correctly in the fiddle. Also, I think you mean to place the code in the head of the document (because of the document.ready handler).
More importantly perhaps the selector $("textarea#test") is run before the document is ready and therefore won't actually find the element correctly. I would recommend assigning inputField in TEX.init:
(function($,window,document,undefined){
var TEX = {
/* Init all functions */
init: function()
{
this.inputField = $("#test");
this.focusTextArea();
},
/* Function update textarea */
focusTextArea: function()
{
this.inputField.text('test');
},
}
$(document).ready(function(){
TEX.init();
});
})(jQuery,window,document);
Updated example: http://jsfiddle.net/xntA2/1/
As a side note, textarea#test should be changed to just #test. The textarea bit is superfluous since there should be only one element on the page with id=test.
Alternative syntax to avoid looking for an element before it exists is to return the element from a function:
(function($,window,document,undefined){
var TEX = {
/* function won't look for element until called*/
inputField:function(){
return $("textarea#test")
},
init: function()
{
this.focusTextArea();
},
focusTextArea: function()
{
this.inputField().text('test');
},
}
$(document).ready(function(){
TEX.init();
});
})(jQuery,window,document);

I realize this is a simplified example...but you are also very close to creating a jQuery plugin and that may also be of benefit. Following provides same functionality as example:
(function($, window, document, undefined) {
$.fn.focusTextArea = function() {
return this.each(function(){
$(this).text('test');
})
};
})(jQuery, window, document);
$(function() {
$('textarea').focusTextArea()
});

Have the following code:
$("#blogs").mouseover(
function () {
$(this).addClass("hover");
$("#home").removeClass("hover");
$("#homepages").removeClass("hover");
$("#apps").removeClass("hover");
$("#facebook").removeClass("hover");
$("#kontakt").removeClass("hover");
$("#content").hide().load("blogs.html", function(){
$("#content").show("slide");
});
});
Works all fine, but now I would like the load() / show() function only be called if #content does not already contain blogs.html.
In other words: I would like to check if blogs.html is already loaded and if yes, simply do nothing and only if not there yet I would load and show it.
Have tried some things with hasClass() and some if-formulas but struggle to get this check.
Tried stuff like this:
$("#content section").hasClass("check_blog").hide().load("blogs.html", function(){
$("#content").show("slide");
Basically I just need to know how I can check if blogs.html is already the contents of #content.
Thanks a lot for any help. Regards, Andi
Add an ID to some element in blogs.html, say blogsloaded, then you can check for it with:
if (!$("#blogsloaded").length)
$("#content").hide().load("blogs.html" ...
Another method would be to store in a variable if you already loaded it:
if (!this.blogsloaded)
{
this.blogsloaded=true;
$("#content").hide().load("blogs.html" ...
}
I would split up your mouseover events into two namespaced events. One which will only run once.
// This event will only run once
$("#blogs").on("mouseover.runonce", function () {
$("#content").load("blogs.html");
});
// because this event will unbind the previous one
$("#blogs").on("mouseover.alwaysrun", function () {
$(this).off("mouseover.runonce");
$(this).addClass("hover");
$("#home").removeClass("hover");
$("#homepages").removeClass("hover");
$("#apps").removeClass("hover");
$("#facebook").removeClass("hover");
$("#kontakt").removeClass("hover");
$("#content").hide();
});
Update a data attribute on #content that contains the url or id of the currently loaded content. Also, you should handle the case where the user hovers over a different section before the previous is done loading.
var request; // use this same var for all, don't re-declare it
$("#blogs").mouseover(function () {
// exit event if the blog is the current content in #content
if ( $("#content").data("current") == "blog") return;
$("#content").data("current","blog");
$(this).addClass("hover");
$("#home").removeClass("hover");
$("#homepages").removeClass("hover");
$("#apps").removeClass("hover");
$("#facebook").removeClass("hover");
$("#kontakt").removeClass("hover");
// if a previous request is still pending, abort it
if ($.isFunction(request.abort) && request.state() == "pending") request.abort();
// request content
request = $.get("blogs.html");
$("#content").hide();
// when content is done loading, update #content element
request.done(function(result){
$("#content").html(result);
});
});
I strongly suggest against using hover for loading content with ajax.
Also, in it's current form, this code is not very re-usable, you'll have to have one for each link. I suggest instead using classes and having only one event binding handling all of the links.
You can do it like this using .has() to detect descendants of content
$("#blogs").mouseover(
function () {
$(this).addClass("hover");
$("#home,#homepages,#apps,#facebook,#kontakt").removeClass("hover");
var $c = $("#content");
if($c.has('.check_blog')){ // if content contains an element with that class
$("#content").hide().load("blogs.html", function(){
$("#content").show("slide");
}
});
});
You could do something like this:
$("#blogs").mouseover(
function () {
$(this).addClass("hover");
$("#home").removeClass("hover");
$("#homepages").removeClass("hover");
$("#apps").removeClass("hover");
$("#facebook").removeClass("hover");
$("#kontakt").removeClass("hover");
if($('#content').html() == '') {
$("#content").hide().load("blogs.html", function(){
$("#content").show("slide");
});
}
});
