I have this code
<style>
.Parent {width:500px;height:500px;background:#000}
.Parent .Child {width:250px;height:250px;background:#F00}
</style>
<div class="Parent">
<div class="child"></div>
</div>
<script>
$(document).ready(function() {
$('.Parent').click(function () {
$(this).hide()
});
/*
But if i click on <div class="Child"></div> ,
<div class="Parent"></div> won't get hidden .
*/
});
</script>
I want my code to hide'.parent',
When I click on areas in .Parent witch doesn't include .Child elementand if the areas I click was included in '.child' area , it don't do anything .
so what would u guys suggest ?
Simply make of event.stopPropagation(); to stop event of child from propagating to parent.
So script becomes:
$('.Parent').click(function () {
$(this).hide();
});
$('.child').click(function (e) {
e.stopPropagation();
});
See the fiddle: "http://jsfiddle.net/sftknxeo/1/"
just do this:
$('.Parent, .child').click(function(e) {
if ($(this).hasClass('child')) {
return false;
}
$(this).hide();
});
$('.Parent, .child').click(function(e) {
if ($(this).hasClass('child')) {
return false;
}
$(this).hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='Parent' style='width:auto; padding:50px; border:red solid 1px;'>
<div class='child' style='width:200px; height:200px;border:green solid 1px;'>
child
</div>
</div>
You can use the event's target to determine what you have clicked on. This way you can also assign an event to happen if you have clicked on the child. (If need be.)
$('.Parent').click(function(e){
if(e.target == this){
$(this).hide()
}
});
DEMO
Quick and dirty version would be simply to add another event handler. Add a click handler to child that hides parent. Then if you click on parent, it hides itself, and if you click on child, it hides parent.
$('.child').click(function (e) {
$('.parent').hide();
});
Not the most elegant solution, sure, but it's quick and easy and should get the job done.
$('.Parent').click(function () {
$(this).css("visibility", "hidden");
$(".Parent" ).children().css("visibility", "visible");
});
If you just want to hide parent then it will do the needful.
Check for the clicked element by looking at the target property of the event object. Here is something you might want to do:
$(function () {
$('.Parent').click(function (e) {
if ($(e.target).hasClass("child")) {
return false;
}
$(this).hide();
});
});
$('.parent').click(function(e) {
if ($(this).hasClass('child')) {
return false;
}
$(this).hide();
});

After the page is loaded, I can add a class with jquery as follows.
$(document).ready(function() {
$("#parent").click(function(){
$(".child").addClass("active");
});
});
but I can't catch the click on the added class, it doesn't work.
$(".child.active").click(function(){
alert('this is clicked');
});
would you please help me.
Since the child isn't .active when the DOM loads, .child.active does not select any elements, so the event handler to the child isn't added. Add the handler to the .child alone instead, and inside the handler, check if it's active:
$(document).ready(function() {
$("#parent").click(function() {
$(".child").addClass("active");
});
});
$('.child').on('click', function() {
if ($(this).is('.active')) {
console.log('this is clicked');
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="parent">
parent
<div class="child">
child
</div>
</div>
Or add the listener inside the parent click handler instead:
$(document).ready(function() {
$("#parent").click(function() {
$(".child")
.addClass("active")
.off('click')
.on('click', function() {
if ($(this).is('.active')) {
console.log('this is clicked');
}
});
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="parent">
parent
<div class="child">
child
</div>

I have this code:
$(function() {
$('#toggle4').click(function() {
$('.toggle4').slideToggle('fast');
return false;
});
});
Which works great and shows the '.toggle4' div but I want to hide it again when clicking outside/away from it.
So I added this:
$(document).click(function() {
$(".toggle4").hide();
});
Which works but it hides the div even when I click inside of the '.toggle4' div (it's an input box for a search form).
Any ideas? Thanks.
That's because when you click inside of .toggle4 that click event bubbles up the DOM and triggers the event you bound to the document. You should be able to fix that with something like:
$('.toggle4').click(function(e){
e.stopPropagation()
})
One possibility is to prevent the click event from bubbling up to the document if it took place inside the toggle.
$(function() {
$('#searchField').click(function() {
$('#toggle').slideToggle('fast');
return false;
});
});
$(document).click(function() {
$("#toggle").hide();
});
$("#toggle").click(function(e) {
e.stopPropagation();
});
#toggle {
width: 100px;
height: 100px;
background: red;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="searchField">
<div id="toggle" class="toggle4"></div>
I have a JS global event handler which looks like this (this is temp code):
$(document).on('click', '.my-class, #box-in-my-class', function(e) {
console.log($(this), 'was clicked!');
if ($(this).is('my-class')) {
$(this).children('.dropdown').toggleClass('active');
}
if ($(this).is('#box-in-my-class')) {
$('#expander').toggleClass('active');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="my-class">
<div class="other-bit"></div>
<div class="dropdown">
<div id="box-in-my-class"></div>
</div>
</div>
<div id="expander"></div>
(the .active class added makes the div bigger - through css).
However, in running this, when I click the #box-in-my-class, I get this in the console:
#box-in-my-class was clicked!
.my-class was clicked!
which toggles the dropdown (closing it).
How do I set it so that when you click the child of an element it does not bubble/propagate/etc. so that I can click the #box-in-my-class w/o running .my-class
Because your event bubbles. In the code you must call e.stopPropagation(); And also you have some missed ')'.
$(document).on('click', '.my-class, #box-in-my-class', function(e) {
e.stopPropagation();
console.log(e.target, 'was clicked!');
if ($(this).is('my-class')) {
$(this).children('.dropdown').toggleClass('active');
}
if ($(this).is('#box-in-my-class')) {
$('#expander').toggleClass('active');
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="my-class">
<div class="other-bit"></div>
<div class="dropdown">
<div id="box-in-my-class">Test 1</div>
</div>
</div>
<div id="expander">Test 2</div>
For more see event bubbling
and e.stopPropagation()
try the following
$(document).on('click', '.my-class, #box-in-my-class', function(e) {
if ($(this).is('.my-class') && $(e.target).is(':not(#box-in-my-class')) {//check if the clicked element is not box-in-my-class
console.log($(this), 'was clicked!');
$(this).children('.dropdown').toggleClass('active');
}
if ($(this).is('#box-in-my-class')) {
$('#expander').toggleClass('active');
}
}

I think you shouldn't use 2 if class when you only need one response.
If I were you, I would write my JS function like this:
if ($(this).is('#box-in-my-class') {
$('#expander').toggleClass('active');
return;
}else if ($(this).is('my-class') {
$(this).children('.dropdown').toggleClass('active');
return;
}
I will check this $('#box-in-my-class') first due to the reason that $('#box-in-my-class') is the child of $(.'my-class').
In this case, if it detected $('#box-in-my-class') is clicked, it will stop the loop. instead of checking $(.'my-class') too.

I'm trying to add this the active class to the element when the user clicks it. Why does it not work? Is there something wrong with the syntax?
HTML code:
<div class="accordion">
<h3>a</h3>
<p class="active">b</p>
<h3>a</h3>
<p>b</p>
<h3>b</h3>
<p>b</p>
<h3>b</h3>
<p>b</p>
</div>
jQuery code:
jQuery(function($) {
$('div.accordion').click(function(e) {
e.preventDefault();
$(this).addClass("active");
});
});
What i wanna do is when the user clicks h3, thats when it sets the p tag below it the active class
You need to bind click event to H3 elements. Also make sure you remove previously active elements:
var $h3 = $('.accordion > h3').click(function(e) {
e.preventDefault();
$h3.next('p').removeClass('active');
$(this).next('p').addClass('active');
});
Demo: http://jsfiddle.net/2DB37/
I'm trying to add the active class to the p tag.
You forgot to add a click event to the p tag:
jQuery(function($) {
$('div.accordion h3').click(function(e) {
e.preventDefault();
$(this).next('p').addClass("active");
});
});
WORKING DEMO
change jQuery to like this
jQuery(function($) {
$('div.accordion p').click(function(e) {
e.preventDefault();
$(this).addClass("active");
});
});
UPDATED DEMO
jQuery(function($) {
$('div.accordion h3').click(function(e) {
e.preventDefault();
$(this).next().addClass("active");
});
});
I would like to change the style on a div with an onclick... and remove the style when clicking somewhere outside of the div.
I have the following code setup... can someone help me to remove the style on the divs if you click anywhere else on the page?
<head>
<style type="text/css">
.account{
width: 100px;
height: 100px;
border: 1px solid #000;
}
.selected{
border: 2px solid #F00;
}
</style>
<script type="text/javascript">
$(document).ready(function(){
$(".account").click(function(){
$(".selected").removeClass("selected");
$(this).addClass("selected");
});
});
</script>
</head>
<body>
<h1>the test</h1>
<div class="account">test 1</div>
<div class="account">test 2</div>
</body>
Thank you very much for any help you can give me!!!
The following should do it:
$(document).on('click', function(e) {
if($(e.target).hasClass('account')) {
// do style change
}
else {
// undo style change
}
});
It binds the event handler to the entire document, so you'd have problems with any event handlers on more specific elements that call e.stopPropagation().
Try this.
$(document).ready(function(){
$(".account").click(function(e){
$(".selected").removeClass("selected");
$(this).addClass("selected");
e.stopPropagation();//This will stop the event bubbling
});
//This event handler will take care of removing the class if you click anywhere else
$(document).click(function(){
$(".selected").removeClass("selected");
});
});
Working demo - http://jsfiddle.net/yLhsC/
Note that you can use on or delegate to handle click event on account elements if there are many on the page.
Something like this.
Using on if using jQuery 1.7+
$('parentElementContainingAllAccounts').on('click', '.account', function(e){
$(".selected").removeClass("selected");
$(this).addClass("selected");
e.stopPropagation();//This will stop the event bubbling
});
Using delegate
$('parentElementContainingAllAccounts').delegate('.account', 'click', function(e){
$(".selected").removeClass("selected");
$(this).addClass("selected");
e.stopPropagation();//This will stop the event bubbling
});
You can achieve this behavior with attaching click listener on body element e.g.:
$("body").click(function(){
});
Try this:
$(document).ready(function() {
$('.account').click(function(e) {
e.stopPropagation();
$(this).addClass("selected");
});
$(document).click(function(){
$('.selected').removeClass('selected');
});
});
