I've got an input box that I want to have save its value when it loses focus.
Pretty straightforward stuff and I'm able to get that done via jQuery's focusout event.
The problem however, is that I want to NOT fire the focusout event when the user clicks on an "X" icon next to the input box (example shown below)
So when the user tabs out of this input box, or clicks outside of the box or they click the green checkbox it should fire the focusout event... but if they click the red "X", it should NOT fire the focusout.
Is this possible to do with JavaScript / jQuery?
EDIT:
Some of you have recommended using event.relatedTarget, but it seems like that's returning null. I'll include my code in question for clarity:
// This is the cancel button with the red X
$("body").on("click", "span[id*='Cancel']", function(e)
{
showLabel($(this));
});
// this is the code to trigger the blur / focusout event
// trouble is that the "e.relatedTarget" is null
$("body").on("focusout", "input, textarea", function (e) {
if($(e.relatedTarget).is("span[id*='Cancel']")){
return false;
}
$(this).siblings("span[id*='OK']").trigger("click");
return false;
});
Here's a screen grab of me debugging this in JS (you'll see that the $(e.relatedTarget) selector returns nothing):
You can cancel de event returning the focus to previous element.
$('#inputText').focusout(function(event) {
setTimeout(function(){
if (document.activeElement.id == "btnCancel") {
$(event.target).focus();
return false;
}
},1);
});
This jsFiddle shows how to do it: https://jsfiddle.net/mpervh3t/
Hope it helps
You must use relatedTarget like this :
$(document).ready(function(){
$(".btn").on("focusout",function(e){
if($(e.relatedTarget).hasClass("red")) {
alert("You clicked on X button");
}
else {
alert("Fire Focus out")
}
})
})
Final code :
<!DOCTYPE html>
<html>
<head>
<style>
.gr {
color: green;
}
.red {
color: red;
}
</style>
</head>
<body>
<input type="text" class="btn"><button class="gr">Ok</button><button class="red">X</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(".btn").on("focusout",function(e){
if($(e.relatedTarget).hasClass("red")) {
alert("You clicked on X button");
}
else {
alert("Fire Focus out")
}
})
})
</script>
</body>
</html>
As per my comment:
"I have had to do a similar type of thing with a blur event. Basically what I had to do was call a setTimeout on the blur to execute my function to save the data, and then on the click event of the X, cancel the timeout. That way, unless the X is clicked, the save function will fire. The delay can be pretty negligable, too."
I found the relevant code
var sliderTimeout = null;
$(".slider-trigger").on("blur", function () {
sliderTimeout = setTimeout(function () {
$(".slider").hide();
}, 100);
});
$(".ui-slider-handle").on("focus", function () {
clearTimeout(sliderTimeout);
});
Here is the full demo of the code in action. It does much more than demonstrate this, but if you examine the behavior of focusing/blur on the "margin" input, you will see that if you blur the margin input, the slider hides, but if you click on the slider, it cancels the hide and stays shown. It's the exact same concept, just a slightly different application.
Here, I did the thing.
https://jsfiddle.net/kowmLf2a/1/
In the blur event I target the related target. See if that related target is the item that I don't want to blur with. If it is then return false.
Code for reference:
$('#input').blur(function(event){
if($(event.relatedTarget).is('#bt2')){
return false;
}
alert($(this).val());
});

How could I tell if the focusout event occured due to an enter press = form submit or just because of clicking away? The event data which goes to the console is of type "focusout" and has no relevant information
$(".clientrow[clientid="+clientid+"] td."+fieldname+"").bind("focusout", function(event){
console.log(event);
setTimeout(function() {
if (!event.delegateTarget.contains(document.activeElement)) {
$(".clientrow[clientid="+clientid+"] td."+fieldname+"").html(
$(".clientrow[clientid="+clientid+"] td."+fieldname+" input[type=text]").val()
);
}
}, 0);
});
Edit: As Oriol pointed in the comments, this will not work in Mozilla. If you are looking only for webkit browsers, you can try this approach. But as a generic solution, try binding an event on submit button and consecutively set a flag which identifies the element. Based on the element, you can detect whether it's an actual blur or not.
You can look out for relatedTarget property in the event.
Demo: http://jsfiddle.net/GCu2D/782/
JS:
$(document).ready(function () {
$("input").on("blur", function (e) {
console.log(e);
if (e.relatedTarget) {
console.log("Because of button");
} else {
console.log("Just a blur")
}
});
});
HTML:
<form>
<input type="text" />
<button type="button">Submit</button>
</form>
You'll have to replace the focusout with blur event. When the blur is due to a click on a button, the relatedTarget property will have button as value but in other cases it will be null.
I am trying to prioritize click event in case two events click and change are fired.
I have a global function similar to "ValidateOnChange" and "ValidateOnClick" to validate input of text box on change and on click event.
Enter some text, it shows up error message. Then try to input correct value and click the Submit button, the error vanishes and this makes user to click the button twice. Here I am trying to fix this double click.
Here is mock up code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body>
<div>Enter any string:</div>
<div><input type="text" id="txtInput" ></input></div>
<div id="divError" style="color: red; display: none;">Please enter 0</div>
<input type="button" value="Submit" id="btnSubmit" ></input>
<script type="text/javascript">
var mouseevent_var = null;
function ValidateOnChange(e) {
var input = $('#txtInput').val();
if (input == '0') {
$('#divError').hide();
} else {
$('#divError').show();
}
}
function ValidateOnClick(e){
alert("Hurray!!! You got it right!");
}
$('#txtInput').mousedown(function (e) {
mouseevent_var = e;
});
jQuery(document).ready(function(){
$('#btnSubmit').click(function(e){
ValidateOnClick(e);
});
$('#txtInput').change(function(e){
ValidateOnChange(e);
});
//User don't want error when they are typing in.
//$('#txtInput').keyup(function() {
//$('#txtInput').trigger("change");
//});
});
</script>
</body>
</html>
The keyup event seemed to be solution but users don't want the error to popup when they are typing in.
Is there any way to list all the triggered events so that I could filter "mousedown" and "mouseup" events for submit button? Or is there any alternative way to prioritize click event ?
There can be many alternatives depending on the situations. I have made few minor changes to avoid the double click issue (comments amended). Basically we need to bind the mousedown event on the button object. There we will set a temporary flag variable to true. In the same time if input's change event gets fired then you can skip the checking if the temporary flag variable is true. Reason behind the double click for triggering the button's click event is better explained here: How to get jQuery click event after append in change event handler
Your updated js code below:
var mouseevent_var = false;
function ValidateOnChange(e) {
// Skip validation if the change event is fired due to user's click on submit button
if(mouseevent_var){ return false; }
var input = $('#txtInput').val();
if (input == 0) {
$('#divError').hide();
} else {
$('#divError').show();
}
}
function ValidateOnClick(e){
mouseevent_var = false; // Reset mouseevent_var to false
alert("Hurray!!! You got it right!");
}
$('#btnSubmit').mousedown(function (e) {
mouseevent_var = true;
});
jQuery(document).ready(function(){
$('#btnSubmit').click(function(e){
ValidateOnClick(e);
});
$('#txtInput').change(function(e){
ValidateOnChange(e);
});
//User don't want error when they are typing in.
//$('#txtInput').keyup(function() {
//$('#txtInput').trigger("change");
//});
});
The above code is just a fix as per your need. But there are other better alternatives too. Ideally you should not have two different validation functions for validating same fields on different events. You must think of managing it with a single function.
I'm trying to trigger an event on an input if the input is clicked or if the input comes in to focus.
The issue i'm having is preventing the event from firing twice on the click as, obviously, clicking on the input also puts it in focus. I've put a very loose version of this on jfiddle to show you what I mean, code as below:
HTML:
<body>
<input type="textbox" name="tb1" class="input1"></input>
<label> box 1 </label>
<input type="textbox" name="tb2" class="input2"></input>
<label> box 2 </label>
</body>
JQuery
$(function () {
$('.input2').click(function() {
alert("click");
});
$('.input2').focus(function() {
alert("focus");
});
});
JSFiddle: http://jsfiddle.net/XALSn/2/
You'll see that when you tab to input2 you get one alert, but if you click you get two. Ideally for my scenario, it needs to be one alert and ignore the other. it also doesn't seem to actually focus.
Thanks in advance for any advice.
How about setting a flag on focus so we can fire on focus and ignore clicks but then listen for clicks on the focussed element too? Make sense? Take a look at the demo jsFiddle - If you focus or click on the unfocussed .index2 it triggers the focus event and ignores the click. Whilst in focus, clicking on it will trigger the click.
I have no idea why you would want this (I cant imagine anyone wanting to click on a focussed element for any reason (because the carat is already active in the field) but here you go:
$(function () {
$('.input2').on("click focus blur", function(e) {
e.stopPropagation();
if(e.type=="click"){
if($(this).data("justfocussed")){
$(this).data("justfocussed",false);
} else {
//I have been clicked on whilst in focus
console.log("click");
}
} else if(e.type=="focus"){
//I have been focussed on (either by clicking on whilst blurred or by tabbing to)
console.log("focus");
$(this).data("justfocussed",true);
} else {
//I no longer have focus
console.log("blur");
$(this).data("justfocussed",false);
}
});
});
http://jsfiddle.net/XALSn/12/
This probably won't be the best answer, but this is a way of doing it. I would suggest adding tab indexes to your inputs and firing the focus event when you blur from another input.
I've added that to this fiddle:
http://jsfiddle.net/XALSn/9/
$(function () {
$('.input2').click(function(e) {
alert("click");
e.preventDefault();
});
});
$('input').blur(function(){
$('input').focus(function() {
alert("focus");
});
});
You can use one thing I am using very often in JS
var doSomething = true;
$(function () {
$('.input2').click(function(e) {
if (doSomething) {
// do something :)
}
doSomething = false;
});
$('.input2').focus(function() {
if (doSomething) {
// do something :)
}
doSomething = false;
});
});
But You have to change value of doSomething on mouseout or foucs over etc. :)
$(function () {
var hasFocus = false;
$("body")
.off()
.on({
click : function()
{
if(!hasFocus)
{
hasFocus = true;
alert("click");
}
},
focus : function()
{
if(!hasFocus)
{
hasFocus = true;
alert("focus");
}
}
},".input2");
});
try setting a flag hasFocus and act accordingly
http://jsfiddle.net/AEVTQ/2/
just add e.preventDefault() on the click event
$(function () {
$('.input2').click(function(e) {
console.log("click");
e.preventDefault();
e.stopPropagation();
});
$('.input2').focus(function() {
console.log("focus");
});
});
If I understand your question right, the e.prevnetDefault() will prevent the browser from automatically focusing on click. Then you can do something different with the click than would with the focus
I have a code like this:
$('#foo').on('click', function(e) {
//do something
});
$('form input').on('change', function(e) {
//do some other things
));
First and second events do actually the same things with the same input field, but in different way. The problem is, that when I click the #foo element - form change element fires as well. I need form change to fire always when the content of input is changing, but not when #foo element is clicked.
That's the question )). How to do this?
Here is the code on jsfiddle: http://jsfiddle.net/QhXyj/1/
What happens is that onChange fires when the focus leaves the #input. In your case, this coincides with clicking on the button. Try pressing Tab, THEN clicking on the button.
To handle this particular case, one solution is to delay the call to the change event enough check if the button got clicked in the meantime. In practice 100 milisecond worked. Here's the code:
$().ready(function() {
var stopTheChangeBecauseTheButtonWasClicked = false;
$('#button').on('click', function(e) {
stopTheChangeBecauseTheButtonWasClicked = true;
$('#wtf').html("I don't need to change #input in this case");
});
$('#input').on('change', function(e) {
var self = this;
setTimeout(function doTheChange() {
if (!stopTheChangeBecauseTheButtonWasClicked) {
$(self).val($(self).val() + ' - changed!');
} else {
stopTheChangeBecauseTheButtonWasClicked = false;
}
}, 100);
});
});
And the fiddle - http://jsfiddle.net/dandv/QhXyj/11/
It's only natural that a change event on a blurred element fires before the clicked element is focused. If you don't want to use a timeout ("do something X ms after the input was changed unless in between a button was clicked", as proposed by Dan) - and timeouts are ugly - you only could go doing those actions twice. After the input is changed, save its state and do something. If then - somewhen later - the button is clicked, retrieve the saved state and do the something similar. I guess this is what you actually wanted for your UI behaviour, not all users are that fast. If one leaves the input (e.g. by pressing Tab), and then later activates the button "independently", do you really want to execute both actions?
var inputval = null, changedval = null;
$('form input').on('change', function(e) {
inputval = this.value;
// do some things with it and save them to
changedval = …
// you might use the value property of the input itself
));
$('#foo').on('click', function(e) {
// do something with inputval
});
$('form …').on('any other action') {
// you might want to invalidate the cache:
inputval = changedval;
// so that from now on a click operates with the new value
});
$(function() {
$('#button').on('click', function() {
//use text() not html() here
$('#wtf').text("I don't need to change #input in this case");
});
//fire on blur, that is when user types and presses tab
$('#input').on('blur', function() {
alert("clicked"); //this doesn't fire when you click button
$(this).val($(this).val()+' - changed!');
});
});
Here's the Fiddle
$('form input').on('change', function(e) {
// don't do the thing if the input is #foo
if ( $(this).attrib('id') == 'foo' ) return;
//do some other things
));
UPDATE
How about this:
$().ready(function() {
$('#button').on('click', function(e) {
$('#wtf').html("I don't need to change #input in this case");
});
$('#input').on('change', function(e) {
// determine id #input is in focus
if ( ! $(this).is(":focus") ) return;
$(this).val($(this).val()+' - changed!');
});
});
Made this custom alert box:
<script type="text/javascript">
$(function () {
var $alert = $('#alert');
if ($alert.length) {
var alerttimer = window.setTimeout(function () {
$alert.trigger('click');
});
$alert.animate({ height: $alert.css('line-height') || '80px' }, 200).click(function () {
window.clearTimeout(alerttimer);
$alert.animate({ height: '0' }, 200);
});
}
});
</script>
I want it to be open until the user chooses to click on it or anywhere else on the screen. How do I make this happen?
Assuming that clicking anywhere (in, or out, of the alert box itself) is supposed to hide/remove the alert:
$('body').click(
function(){
if ($alert.is(':visible')){
$alert.hide();
}
});
should work, I think.
If you want to justs get rid of it, try calling the hide() function when an onclick event is triggered.
$.click(function() {
$alert.hide();
});
The top answer here is excellent IMO. It covers the part about anywhere else on the screen.
The way to do it is to bind a click event to the body and stop propagation on any event that happens inside the area that isn't supposed to trigger closing the alert.
