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");
}

</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 = $("#clickable a").attr("href");
window.location = url;
return false;
});
All solution are complicated and of jscript. Here is the simplest version:
var IsChildWindow=false;
function ParentClick()
{
if(IsChildWindow==true)
{
IsChildWindow==false;
return;
}
//do ur work here
}
function ChildClick()
{
IsChildWindow=true;
//Do ur work here
}
<a onclick="return false;" href="http://foo.example">I want to ignore my parent's onclick event.</a>
I am triyng to disable mouse wheel on number inputs because users can make the mistake of scrolling down just after updating the value.
I found this link :
https://gist.github.com/pererinha/aaef044b021bbf7372e5
So i added the directive in my app :
.directive('ignoreMouseWheel', function ($document) {
return {
restrict: 'A',
link: function (scope, element) {
element.bind('mousewheel', function (event) {
var scrollAmount = event.originalEvent.wheelDelta * -1 + $document.scrollTop();
event.preventDefault();
$document.scrollTop(scrollAmount);
});
}
}
});
It works with Chrome but on firefox, when i focus in a field, if i scroll, number is updated.
Can you help me to disable it ?
Thanks
WebKit desktop browsers add little up down arrows to number inputs called spinners. You can insert css code
turn them off visually like this:
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}
Note that some other functionality still exists, like being able to increment the number via the scroll wheel on a mouse.

I am using polymer v1.9.1 and testing on Chrome.
I have a custom element containing a <paper-input>, and I want its text color to depend on some other property. This color is determined by the custom properties --paper-input-container-input-color or --primary-text-color, so I set a class-dependent value for those:
#input { --primary-text-color: red; }
#input.green { --primary-text-color: green; }
<paper-input id='input' class$='[[_getClasses(checked)]]'></paper-input>
_getClasses: function(checked) { return checked ? '':'green'; }
The text is always red, I guess because of this limitation in the shim (which I guess my browser must be using). So I add a call to updateStyles:
_getClasses: function(checked) {
this.async(function() {
this.$.input.updateStyles();
});
return checked ? '':'green'; }
}
Now it works correctly after checked first changes, but the initial state is incorrect (ie if checked is initially false, it is initially red but should be green). I tried adding another async(updateStyles()) to ready but no luck (yet if I call input.updateStyles() from the javascript console it corrects itself). How can I work around this?
Complete example: http://embed.plnkr.co/VC1ZMw9iyUO3K2SQq5Oy/
I've updated the plunk with the fix.
I've updated styles in attached callback instead of ready.
_getClasses: function(checked) {
return checked ? '' : 'green';
},
attached: function() {
this.updateStyles();
}
I have
<ons-toolbar-button id="buttonNext" disabled >Next</ons-toolbar-button>
and I want to programmatically enable it or disable it again.
I found that in ons-button, there is methods like setDisabled(true) but not for ons-toolbar-button.
Could someone shed some light on how to programmatically enable/disable ons-toolbar-button?
thanks.
Toolbar buttons are usually removed or hidden rather than disabled, that's why there are no methods for ons-toolbar-button. setDisabled just adds disabled attribute to the element, nothing else. You can implement it for ons-toolbar-button like this:
setDisabled = function(boolean) {
if (boolean) {
document.querySelector('ons-toolbar-button').setAttribute('disabled', '');
} else {
document.querySelector('ons-toolbar-button').removeAttribute('disabled');
}
}
Then of course you need some CSS:
ons-toolbar-button[disabled] {
opacity: 0.3;
cursor: default;
pointer-events: none;
}

I have an element that appears when the user clicks a button elsewhere on the screen. The element appears to come out of the top of the screen. The element by default needs to be tucked out of view above the screen, so I will have a margin-top style that is based on the height of the element (and will be a negative value). This cannot be hardcoded in css because the element height may vary. When I click the button, I want the element margin-top to change to 0 and I want a transition animation.
The sample shown on angularJS documentation is for adding a removing a class. This would work fine if I knew the values to be set and could code them in CSS, however I cannot. What is the correct way to solve this?
The code below works for displaying and hiding my element using a margin but there is no animation. How do I trigger an animation here when the margin changes?
https://docs.angularjs.org/guide/animations
Quote Total: {{salesPriceTotal + taxesTotal - tradeInsTotal | currency}}
<div class="totals" ng-style="setTopMargin()">
// totals stuff here.
</div>
$scope.setTopMargin = function() {
return {
marginTop: $scope.marginTop
}
};
$scope.$watch('showTotals', function() {
var margin = $scope.showTotals ? 10 : -160 + $scope.modelTotals.length * -200;
$scope.marginTop = margin.toString() + 'px';
});
I added the following code per a suggested solution, but this code is never hit.
myApp.animation('.totals', function () {
return {
move: function (element, done) {
element.css('opacity', 0);
jQuery(element).animate({
opacity: 1
}, done);
// optional onDone or onCancel callback
// function to handle any post-animation
// cleanup operations
return function (isCancelled) {
if (isCancelled) {
jQuery(element).stop();
}
}
},
}
});
As the documentation explains: "The same approach to animation can be used using JavaScript code (jQuery is used within to perform animations)".
So you basically needs to use animate() from jQuery to do what you want.
