I'm currently using jQuery to make a div clickable and in this div I also have anchors. The problem I'm running into is that when I click on an anchor both click events are firing (for the div and the anchor). How do I prevent the div's onclick event from firing when an anchor is clicked?
Here's the broken code:
JavaScript
var url = $("#clickable a").attr("href");
$("#clickable").click(function() {
window.location = url;
return true;
})
HTML
<div id="clickable">
<!-- Other content. -->
I don't want #clickable to handle this click event.
</div>
Events bubble to the highest point in the DOM at which a click event has been attached. So in your example, even if you didn't have any other explicitly clickable elements in the div, every child element of the div would bubble their click event up the DOM to until the DIV's click event handler catches it.
There are two solutions to this is to check to see who actually originated the event. jQuery passes an eventargs object along with the event:
$("#clickable").click(function(e) {
var senderElement = e.target;
// Check if sender is the <div> element e.g.
// if($(e.target).is("div")) {
window.location = url;
return true;
});
You can also attach a click event handler to your links which tell them to stop event bubbling after their own handler executes:
$("#clickable a").click(function(e) {
// Do something
e.stopPropagation();
});
Use stopPropagation method, see an example:
$("#clickable a").click(function(e) {
e.stopPropagation();
});
As said by jQuery Docs:
stopPropagation method prevents the event from bubbling up the DOM
tree, preventing any parent handlers from being notified of the event.
Keep in mind that it does not prevent others listeners to handle this event(ex. more than one click handler for a button), if it is not the desired effect, you must use stopImmediatePropagation instead.
Here my solution for everyone out there looking for a non-jQuery code (pure javascript)
document.getElementById("clickable").addEventListener("click", function(e) {
e = window.event || e;
if(this === e.target) {
// put your code here
}
});
Your code wont be executed if clicked on parent's children
If you do not intend to interact with the inner element/s in any case, then a CSS solution might be useful for you.
Just set the inner element/s to pointer-events: none
in your case:
.clickable > a {
pointer-events: none;
}
or to target all inner elements generally:
.clickable * {
pointer-events: none;
}
This easy hack saved me a lot of time while developing with ReactJS
Browser support could be found here: http://caniuse.com/#feat=pointer-events
Inline Alternative:
<div>
<!-- Other content. -->
<a onclick='event.stopPropagation();' href="http://foo.example">I don't want #clickable to handle this click event.</a>
</div>
You can also try this
$("#clickable").click(function(event) {
var senderElementName = event.target.tagName.toLowerCase();
if(senderElementName === 'div') {
// Do something here
} else {
// Do something with <a> tag
}
});
Writing if anyone needs (worked for me):
event.stopImmediatePropagation()
From this solution.
Using return false; or e.stopPropogation(); will not allow further code to execute. It will stop flow at this point itself.
If you have multiple elements in the clickable div, you should do this:
$('#clickable *').click(function(e){ e.stopPropagation(); });
I compare to ev.currentTarget when this is not available (React, etc).
$("#clickable").click(function(e) {
if (e.target === e.currentTarget) {
window.location = url;
return true;
}
})
Here's an example using Angular 2+
For example, if you wanted to close a Modal Component if the user clicks outside of it:
// Close the modal if the document is clicked.
#HostListener('document:click', ['$event'])
public onDocumentClick(event: MouseEvent): void {
this.closeModal();
}
// Don't close the modal if the modal itself is clicked.
#HostListener('click', ['$event'])
public onClick(event: MouseEvent): void {
event.stopPropagation();
}
If it is in inline context, in HTML try this:
onclick="functionCall();event.stopPropagation();
e.stopPropagation() is a correct solution, but in case you don't want to attach any event handler to your inner anchor, you can simply attach this handler to your outer div:
e => { e.target === e.currentTarget && window.location = URL; }
var inner = document.querySelector("#inner");
var outer = document.querySelector("#outer");
inner.addEventListener('click',innerFunction);
outer.addEventListener('click',outerFunction);
function innerFunction(event){
event.stopPropagation();
console.log("Inner Functiuon");
}
function outerFunction(event){
console.log("Outer Functiuon");
}
<!DOCTYPE html>

<div id="inner" style="width:35px;height:35px;background-color:yellow;"></div>
</div>
</body>
</html>
You need to stop the event from reaching (bubbling to) the parent (the div).
See the part about bubbling here, and jQuery-specific API info here.
To specify some sub element as unclickable write the css hierarchy as in the example below.
In this example I stop propagation to any elements (*) inside td inside tr inside a table with the class ".subtable"
$(document).ready(function()
{
$(".subtable tr td *").click(function (event)
{
event.stopPropagation();
});
});
You can check whether the target is not your div-element and then issue another click event on the parent after which you will "return" from the handle.
$('clickable').click(function (event) {
let div = $(event.target);
if (! div.is('div')) {
div.parent().click();
return;
}
// Then Implement your logic here
}
Here is a non jQuery solution that worked for me.
<div style="background:cyan; width:100px; height:100px;" onclick="if (event.srcElement==this) {console.log('outer');}">
<a style="background:red" onclick="console.log('inner');">Click me</a>
</div>
for those that are not using jQuery
document.querySelector('.clickable').addEventListener('click', (e) =>{
if(!e.target.classList.contains('clickable')) return
// place code here
})
In case someone had this issue using React, this is how I solved it.
scss:
#loginBackdrop {
position: absolute;
width: 100% !important;
height: 100% !important;
top:0px;
left:0px;
z-index: 9; }
#loginFrame {
width: $iFrameWidth;
height: $iFrameHeight;
background-color: $mainColor;
position: fixed;
z-index: 10;
top: 50%;
left: 50%;
margin-top: calc(-1 * #{$iFrameHeight} / 2);
margin-left: calc(-1 * #{$iFrameWidth} / 2);
border: solid 1px grey;
border-radius: 20px;
box-shadow: 0px 0px 90px #545454; }
Component's render():
render() {
...
return (
<div id='loginBackdrop' onClick={this.props.closeLogin}>
<div id='loginFrame' onClick={(e)=>{e.preventDefault();e.stopPropagation()}}>
... [modal content] ...
</div>
</div>
)
}
By a adding an onClick function for the child modal (content div) mouse click events are prevented to reach the 'closeLogin' function of the parent element.
This did the trick for me and I was able to create a modal effect with 2 simple divs.
If a child element is clicked, then the event bubbles up to the parent and event.target !== event.currentTarget.
So in your function, you can check this and return early, i.e.:
var url = $("#clickable a").attr("href");
$("#clickable").click(function(event) {
if ( event.target !== event.currentTarget ){
// user clicked on a child and we ignore that
return;
}
window.location = url;
return true;
})
This is what you are looking for
mousedown event. this works on every DOM elements to prevent javascript focus handler like this:
$('.no-focus').mousedown(function (e) {
e.prevenDefault()
// do stuff
}
in vue.js framework, you can use modifier like this:
<span #mousedown.prevent> no focus </span>
Note that using on the input will prevent text selection handler
add a as follows:
....
or return false; from click handler for #clickable like:
$("#clickable").click(function() {
var url = $("#clickable a").attr("href");
window.location = url;
return false;
});
All solution are complicated and of jscript. Here is the simplest version:
var IsChildWindow=false;
function ParentClick()
{
if(IsChildWindow==true)
{
IsChildWindow==false;
return;
}
//do ur work here
}
function ChildClick()
{
IsChildWindow=true;
//Do ur work here
}
<a onclick="return false;" href="http://foo.example">I want to ignore my parent's onclick event.</a>
I have a dropdown menu within a div element. Calling the javascript function HideDropdown() hides the menu when any other main link on the page is clicked (not including links in the dropdown menu itself):
<script>
function HideDropdown() {
$("#dropdown-content-id2").hide();
$("#dropdown-content-id").hide();}
</script>
I also want to call HideDropdown() to hide the menu (if it's open) when I click anywhere on the body except the dropdown menu itself.
In the body tag I inserted this:
<body onload="ShowPage(1)" onclick="HideDropdown()">
That successfully hides the dropdown when I click anywhere on the screen. I want to exclude clicks on the link that shows the dropdown menu and anywhere on the dropdown menu itself, so I revised the body tag:
<body onload="ShowPage(1)" onclick="HideDropdownCall(e)">
and created a new javascript function to call from the body onclick:
<script>
function HideDropdownCall(e) {
if(e.target.id != "dropdown-content-id" ){
HideDropdown();
}
</script>
but that didn't work, so I revised it:
<script>
function HideDropdownCall(e) {
if(e.target.id != "dropdown-content-id" ){
$("#dropdown-content-id2").hide();
$("#dropdown-content-id").hide();}
}
</script>
but that still doesn't work.
So my question is, how can I call the HideDropdown() function from a body click, filtered so that clicks on the dropdown menu itself don't count?
Thanks very much for any help.
EDIT:
After some work, I whittled down my problem to this: I can call the HideDropdown() function from the body tag like this:
<body onload="ShowAjax(1)" onclick="HideDropdown()">
That works. But when I change it to the same function with qualifications and (not if the click event is fired by the dropdown menu), the dev console says "TypeError: e is undefined" so it has something to do with the conditional statement:
<body onload="ShowAjax(1)" onclick="HideDropdown_B()">
<script>
function HideDropdown_B(e) {
if(e.target.id != "dropdown-content-id" ){
$("#dropdown-content-id2").hide();
$("#dropdown-content-id").hide();}
}
</script>
So my problem now boils down to finding out why the new function above returns a type error when the same program without the if statement works.
What you could do is add the property data-prevent='true' on the elements that you want to prevent hiding the dropdown.For example:
Link
and modify your function to filter out those elements like so:
function hideDropdown(evt) {
evt.preventDefault(); // you might not need this (usefull in case of a tags & preventing redirects)
if (!evt.target.getAttribute('data-prevent') || evt.target.getAttribute('data-prevent') === 'false') {
$("#dropdown-content-id2").hide();
$("#dropdown-content-id").hide();
}
}
Here is an example of how it could be done:
let menu = document.getElementById('menu');
document.body.addEventListener('click', e => {
if (!menu.contains(e.target))
console.log('close menu');
});
<div id='menu'><a id='link'>link</a> and menu</div>
document body here
However, you may actually want to close menu depending on which link were clicked.
Another way to do so:
let menu = document.getElementById('menu');
menu.addEventListener('click', e => e.stopPropagation());
document.body.addEventListener('click', e => console.log('close menu'));
<div id='menu'><a id='link'>link</a> and menu</div>
document body here
Thanks to everyone who answered. I solved this problem. Here is the solution:
In the body tag:
<body onload="ShowPage(1)" onclick="HideDropdown_B(event)">
The HideDropdown_B function:
<script>
function HideDropdown_B(event) {
TargetID = event.target.getAttribute('id');
TargetClass = event.target.getAttribute('class');
if((TargetID != "dropdown-content-id") && (TargetClass != "button_01") && (TargetClass != "dropdown") && (TargetClass != "button_dropdown") ) {
$("#dropdown-content-id2").hide();
$("#dropdown-content-id").hide();}
}
</script>
That works to close the menu when clicking anywhere except the excluded elements.
Here's my function,
$(document).ready(function () {
$('.a').click(function () {
var here = $(this).next('.b');
if (here.is(":visible")) {
here.hide();
} else {
here.show();
}
return false;
});
});
So, whenever I click the button it opens a small tab on same webpage & whenever I click it again it closes it. But once I open the tab I can't close it by just clicking somewhere on webpage apart from tab. I have to click the button again to close it.
How can I close tab just by clicking somewhere on webpage also by on the button?
I end up searching for this on almost every project, so I made this plugin:
jQuery.fn.clickOutside = function(callback){
var $me = this;
$(document).mouseup(function(e) {
if ( !$me.is(e.target) && $me.has(e.target).length === 0 ) {
callback.apply($me);
}
});
};
It takes a callback function and passes your original selector, so you can do this:
$('[selector]').clickOutside(function(){
$(this).removeClass('active'); // or `$(this).hide()`, if you must
});
Nice, chainable, elegant code.
On document click, the closest helps to check whether the tab has been clicked or not:
$(document).click(function (e) {
if($('.b').is(':visible')&&!$(e.target).closest('.b').length){
$('.b').hide();
}
});
You want to check for a click on the body :
$("body").click(function(e) {
if(e.target.id !== 'menu'){
$("#menu").hide();
}
});
menu would be the id of the menu.
If the body is clicked and the id of the div clicked doesn't equal that of the menu, then it closes.
Check this implementation
jQuery(document).ready(function() {
$(document).on('click','body, #btn',function(ev){
ev.stopPropagation()
if(ev.target.id== "btn"){
if($('#modal').is(':visible')) {
$('#modal').fadeOut();
} else{
$('#modal').fadeIn();
}
} else {
$('#modal').fadeOut();
}
});
});
html, body {
height: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="btn">
Click Me!
</button>
<div id="modal" style="background-color:red;display:none;">
BLA BLA BLA
</div>
To check if the clicked element is outside of a given container, i.e. a menu, we can simply check if the event target is a child of the container. Using JQuery -
$('body').click(function(e) {
if ( 0 === $(e.target).parents('#container-id').length ) {
/// clicked outside -> do action
}
})
you have to add a click listener to the parent element, like here:
$('.parent-div').click(function() {
//Hide the menus if visible
});
Also because click events bubbled up from child to the parent,
you can exclude the click on the child element to get bubbled up and count as the parent click too. you can achieve this like below:
//disable click event on child element
$('.child-div').click(function(event){
event.stopPropagation();
});
It's a rich-text editor,there is a div show the content users typed in, just like this:
<div class=‘content’>
<iframe data-role=text-editable.></iframe>
</div>
When i click a icon who's used to call the color panel，the panel will show.And i wish when i click outside the panel,it will be hide.so my code is:
var color_panel = $('.color-panel');
color_panel.on("clickoutside", function (e) {
var t = $(e.target);
if ($.contains(color_panel[0], t[0]))
return;
color_panel.hide();
})
It works well when i click outside the panel will disappear except i click the iframe.when i click the ifame,nothing happens,the panel is still shown,
Help......i want to know the reason .please...is the ifame not the dom element outside the panel?
You can listen for outside clicks by listening for clicks on the body element of the webpage (so, clicking on anything element) and then you can exclude your .color_panel from this event by making another event that says "when I get clicked on, ignore any other clicks". The effect will be exactly what you want, that you can listen for outside clicks:
var panelOpen = false;
$('body').click(function(event) {
if (panelOpen) {
panelOpen = false;
color_panel.hide();
}
});
$('.color_panel').click(function(event) {
panelOpen = true;
//callYourMethodToShowThePanelHere();
e.preventDefault(); // these methods will stop the body click event
e.stopPropagation();
return false;
});
I'm trying to write a web app which replaces the context menu (right-click menu) with my own customized ones. I want it so that when the user clicks on a table row, they get one certain context menu and when they click on the background of the page, they get a different one.
I have already written the menus and gotten them working. The problem comes in when trying to figure out how to get the background's menu to show ONLY when clicking on the background and how to get the table row's menu to show when that is clicked.
I tried using document.body.oncontextmenu for the body and and setting the oncontextmenu function for each table row, but the body's oncontextmenu function overrides the row's so I get the wrong menu. The menu for the table rows DOES work if I stop using the body's menu, so that's not the issue.
I could be using the wrong events, so is there a different event for just the background (and not the elements on top of the background)? Or a way to "prioritize" the events so the table row's function takes precedence?
This is how the code looks:
var tableMenu;
var bodyMenu;
window.onload = function()
{
bodyMenu = new rightClickMenu("bodyMenu");
document.body.oncontextmenu = function() { bodyMenu.show(); tableMenu.hide(); }
bodyMenu.add("Add Entry", function()
{
alert("ADD");
});
tableMenu = new rightClickMenu("tableMenu", "tblSims");
simRows = getElementsByClassName("trSimRow");
for (var i in simRows)
simRows[i].oncontextmenu = function() { tableMenu.show(this.id.substring(2)); bodyMenu.hide(); }
tableMenu.add("Delete Entry", function(mac)
{
alert("DELETE");
});
document.body.onclick = function()
{
bodyMenu.hide();
tableMenu.hide();
};
}
You can capture the target element, e.g.:
$('*').click(function(e) {
alert(e.target);
alert(e.target.tagName);
if(e.target.tagName == 'html') {
// show background menu
}
});
You have to work with the Javascript Event Propagation model. What happens is that your click event is automatically passed down the layers of objects on a page that have been registered as event listeners, unless you explicitly tell it to stop, try something like this:
function setupClickHandlers()
{
document.getElementsByTagName('body')[0].onclick = doBodyMenu;
document.getElementById('tableID').onclick = doTableMenu;
}
function doBodyMenu()
{
//do whatever it does
}
function doTableMenu(e)
{
//do whatever it does
//stop the event propagating to the body element
var evt = e ? e : window.event;
if (evt.stopPropagation) {evt.stopPropagation();}
else {evt.cancelBubble=true;}
return false;
}
This should deal with the way each browser handles events.
$( document ).ready(function() {
var childClicked = false;
// myContainer is the nearest container div to the clickable elements
$("#myContainer").children().click(function(e) {
console.log('in element');
childClicked = true;
});
$("#myContainer").click(function(e){
if(!childClicked) {
console.log('in background');
e.preventDefault();
e.stopPropagation();
}
childClicked = false;
});
});
#myContainer {
width:200px;
height:200px;
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myContainer" style="">
link
<div style="width:50px;height:50px;background-color: white;">
another link
</div>
</div>
