i have this HTML page
<html>
<body>
<div>a</div>
<div>b</div>
<div>c</div>
<div>d</div>
<div id='in_or_out'>e</div>
<div>f</div>
</body>
</html>
a,b,c,d,e and f could be divs also not just a plain text.
I want to get the mouse click event, but how could i know if it's inside or outside #in_or_out div ?
EDIT :: guys, i know how to check if the div is click or not, but i want my event to be fired when the click is outside that div
$("body > div").click(function() {
if ($(this).attr("id") == "in_or_out") {
// inside
} else {
// not inside
}
});
EDIT: just learned, that there is a negate:
$("body > div:not(#in_or_out)").click(function(e) {
// not inside
});
If you want to detect whether or not you've clicked inside or outside the div, set the event handler on the documentElement and let it propagate from the other elements upwards:
$("html").click(function (e)
{
if (e.target == document.getElementById("in_or_out"))
alert("In");
else
alert("Out!");
});
Maybe this one will help you
$('body').click(function(){
//do smth
});
$('div#in_or_out').click(function(e){
e.stopPropagation();
// do smth else
});
Depends what you want. If you only want to execute code, when it was inside #in_or_out, you can do:
$('#in_or_out').click(function(){ /* your code here */ });
You can have a status variable that says whether the mouse is in #in_or_out or not:
var inside = false;
$('#in_or_out').hover(function() { inside = true; }, function() { inside = false; });
Then whenever a click occurs you can check with inside whether the click was inside in_or_out or not.
Reference: .hover()
Update:
No matter to which element you bind the click handler, you can always do this:
$('element').click(function() {
if ($(this).attr('id') !== 'in_or_not') {
}
});
for inside it would be
$("#in_or_out").click(function() {
// do something here
});
for outside...I've got no idea.
Edit: You could try to do the same for body-tag (assigning a click-handler to the document itself). But I'm not sure if both events would fire by that.
Like this?
$("#in_or_out").click(function() {
alert("IN DIV!");
});

I have a page which has an event as follows:
$(document).on("click","#div",function(e){
//do the operation
});
This event gets executed on both page load as well as div click.
I need to differentiate between these two calls inside the event, because I have to write a condition extra only on div click and not on load .
How do I know if its from page load or div click?
Edit
On load:
$(default).find('a').trigger("click") ; makes it trigger on load
$(document).on("click", "#div", function(e) {
if (e.originalEvent !== undefined) {//use the originalEvent
alert('human');
} else {
alert('load click')
}
});
$('#div').click();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='div'>click</div>
//You can check for originalEvent element present in event object.
$(document).ready(function() {
$(document).on("click","#div",function(e){
if(e.originalEvent) {
alert('clicked manually');
} else {
alert('page load');
}
});
$('#div').click();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div id="div">
div
</div>
</body>
You could set a boolean variable in each of these like:
var fromPageLoad = false;
var fromDivClick = false;
$(window).load(function() {
fromPageLoad = true;
//do the operation
});
$(document).on("click","#div",function(e){
fromDivClick = true;
//do the operation
});
and then check which condition is true with an if or a switch statement.
[EDIT]
Unless you want alerts popping out of the blue like the other answers suggest settings variables as so is the way to go.
if u need to perform any action on page load you have to specify as below
$(document).load(function(){
alert("event on page load");
});
if the div click event then as below
$(#div).onclick(function(){
alert ("on div click");
})
I have one html div on my jsp page, on that i have put one anchor tag, please find code below for that,
<div class="expandable-panel-heading">
<h2>
<a id="ancherComplaint" href="#addComplaint"
onclick="markActiveLink(this);">ABC</a>
</h2>
</div>
js code
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
function markActiveLink(el) {
alert($(el).attr("id"));
}
here I when I click on div I got alert with 123 message, its fine but when I click on ABC I want message I want to call markActiveLink method.
JSFiddle
what is wrong with my code? please help me out.
The problem was that clicking the anchor still triggered a click in your <div>. That's called "event bubbling".
In fact, there are multiple solutions:
Checking in the DIV click event handler whether the actual target element was the anchor
→ jsFiddle
$('.expandable-panel-heading').click(function (evt) {
if (evt.target.tagName != "A") {
alert('123');
}
// Also possible if conditions:
// - evt.target.id != "ancherComplaint"
// - !$(evt.target).is("#ancherComplaint")
});
$("#ancherComplaint").click(function () {
alert($(this).attr("id"));
});
Stopping the event propagation from the anchor click listener
→ jsFiddle
$("#ancherComplaint").click(function (evt) {
evt.stopPropagation();
alert($(this).attr("id"));
});
As you may have noticed, I have removed the following selector part from my examples:
:not(#ancherComplaint)
This was unnecessary because there is no element with the class .expandable-panel-heading which also have #ancherComplaint as its ID.
I assume that you wanted to suppress the event for the anchor. That cannot work in that manner because both selectors (yours and mine) select the exact same DIV. The selector has no influence on the listener when it is called; it only sets the list of elements to which the listeners should be registered. Since this list is the same in both versions, there exists no difference.
Try this
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
$('#ancherComplaint').click(function (event) {
alert($(this).attr("id"));
event.stopPropagation()
})
DEMO
Try following :
$('.expandable-panel-heading').click(function (e) {
if(e.target.nodeName == 'A'){
markActiveLink(e.target)
return;
}else{
alert('123');
}
});
function markActiveLink(el) {
alert($(el).attr("id"));
}
Here is the working demo : http://jsfiddle.net/JVrNc/4/
Change your jQuery code with this. It will alert the id of the a.
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
markActiveLink();
alert('123');
});
function markActiveLink(el) {
var el = $('a').attr("id")
alert(el);
}
Demo
You need to read up on event bubbling and for sure remove inline event handling if you have jQuery anyway
Test the click on the div and examine the target
Live Demo
$(".expandable-panel-heading").on("click",function (e) {
if (e.target.id =="ancherComplaint") { // or test the tag
e.preventDefault(); // or e.stopPropagation()
markActiveLink(e.target);
}
else alert('123');
});
function markActiveLink(el) {
alert(el.id);
}
I would have used stopPropagation like this:
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
$('#ancherComplaint').on('click',function(e){
e.stopPropagation();
alert('hiiiiiiiiii');
});
Try out this example, the onclick is still called from your HTML, and event bubbling is stopped.
<div class="expandable-panel-heading">
<h2>
<a id="ancherComplaint" href="#addComplaint" onclick="markActiveLink(this);event.stopPropagation();">ABC</a>
</h2>
</div>
http://jsfiddle.net/NXML7/1/
put your jquery function inside ready function for call click event:
$(document).ready(function() {
$("#ancherComplaint").click(function () {
alert($(this).attr("id"));
});
});
when click on div alert key
$(document).delegate(".searchbtn", "click", function() {
var key=$.trim($('#txtkey').val());
alert(key);
});
I am trying to check whether or not a particular element has been clicked but am having trouble doing so. Here is my HTML:
<div id="my_special_id" class="switch switch-small has-switch" data-on="success" data-off="danger">
<div class="switch-on switch-animate"><input type="checkbox" checked="" class="toggle">
<span class="switch-left switch-small switch-success">ON</span>
<label class="switch-small"> </label>
<span class="switch-right switch-small switch-danger">OFF</span>
</div>
</div>
Here is my jQuery:
<script type="text/javascript">
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
</script>
I am guessing that my id "my_special_id" is not what is actually being clicked?
I guess click event should have event parameter.
$(document).ready(function() {
$('#my_special_id').click(function(e) {
if (e.target check condition) {
window.alert('ON!');
}
});
});
parameter 'e' above specified is the event object that has all info about click event.
so if u check all info under 'e.tartget', u will be able to find out which one is clicked.
Hope it's helpful for you.
Cheers :)
Since you are looking for a alert when the checkbox is clicked
$(document).ready(function() {
$('#my_special_id input.toggle').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
Demo: Fiddle
Simply put alert when you click on that particular class switch-on
<script type="text/javascript">
$(document).ready(function() {
$('#my_special_id div:first-child .switch-on').on('click',function() {
window.alert('ON!');
});
});
</script>
Or even try like
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($(this + 'div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
This JavaScript works for me.
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
alert("On!");
}
});
});
You are sure you have JQuery?
Your code looks fine I think either you have a syntax error somewhere else or you do not have JQuert.
does this alert?
$(document).ready(function() {
alert("Jquery works");
});
The click event will trigger to whatever you're bound do. the only time you'd have to be worried is if you bound to both a parent and child (e.g. you had listed #my_special_id,.switch-small--then you'd have to look at e.target).
With that said, you can use scope to limit how jQuery finds the div:first-child. I'm not 100% sure what you're after, but the below appears to do what you're after:
$(document).ready(function() {
$('#my_special_id').click(function() {
// look for div:first-child within `this` (where `this=#my_special_id`
// per the .click selector above)
if ($('div:first-child',this).hasClass('switch-on')) {
window.alert('ON!');
}
});
});
If you're looking to bind to the on/off separately, you may want to change it around a bit. we can still check for .switch-on, just have to traverse differently:
// here we bind to the on/off buttons and not the container
$('#my_special_id .switch-small').click(function(){
// you want the facsimilee of `div:first-child`, so (because we're now
// within that node, we use .parent() to get back up to it
var $firstChild = $(this).parent();
if ($parent.hasClass('switch-on')){
alert('ON!');
}
});
The code below I use to create a sliding menu. I need to know how to unbind the function attached to the click event and re-attach it some other time. (using jQuery 1.7.2)
$(document).ready(function(){
$('.section').hide();
$('.header').click(function(){
if($(this).next('.section').is(':visible'))
{
$('.section:visible').slideUp()
$('.arrows:visible').attr("src","right.gif")
}
else
{
$('.section').slideUp();
$(this).next('.section').slideToggle();
$(this).find('.arrows').attr("src","down.gif")
});
});
The code below is what I have so far
$('#printVers').click(function(){
if($('#formVersion').val() != "Print")
{
$('.header').unbind('click');
}
else
{
//else re-attach functionality?
}
});
Thanks
Simply make a named function. You can go low tech here and back to basics to unbind and reattach specific events.
function doStuff()
{
if($(this).,next('.section').is(':visible'))
...
}
$('.header').on('click', doStuff);
$('.header').off('click', doStuff);
Instead of unbind and re-bind, I suggest you to add a simple class to .header and check for the class in the click handler. See below,
$('#printVers').click(function(){
if($('#formVersion').val() != "Print")
{
$('.header').addClass('dontClick');
} else {
$('.header').removeClass('dontClick');
}
});
And in your .header click handler,
$('.header').click(function(){
if ($(this).hasClass('dontClick')) {
return false;
}
//rest of your code
If you insist on having a unbind and bind, then you can move the handler to a function and unbind/bind the function any number of time..
You can try something like this.
$('#printVers').click(function(){
if($('#formVersion').val() != "Print")
{
$('.header').addClass('clickDisabled');
}
else
{
$('.header').removeClass('clickDisabled');
}
});
And then in the click handler check for this class.
$(document).ready(function(){
$('.section').hide();
$('.header').click(function(){
if(!$(this).hasClass('clickDisabled')){
...
...
}
});
});
Why not make that top section a function, and then call it in your else statement?
You could try setting a variable as a flag. var canClick = ($('#formVersion').val() != 'Print'); Then in the click handler for your .header elements check to see if canClick is true before executing your code.
If you still want to remove the handler you can assign the events object to a variable. var eventObj = #('.header').data('events'); That will give you an object with all the handlers assigned to that object. To reassign the click event it would be like $('.header').bind('click', eventObj.click[0]);
After trying so hard with bind, unbind, on, off, click, attr, removeAttr, prop I made it work.
So, I have the following scenario: In my html i have NOT attached any inline onclick handlers.
Then in my Javascript i used the following to add an inline onclick handler:
$(element).attr('onclick','myFunction()');
To remove this at a later point from Javascript I used the following:
$(element).prop('onclick',null);
This is the way it worked for me to bind and unbind click events dinamically in Javascript. Remember NOT to insert any inline onclick handler in your elements.
You could put all the code under the .click in a separated function
function headerClick(){
if($(this).next('.section').is(':visible'))
{
$('.section:visible').slideUp()
$('.arrows:visible').attr("src","right.gif")
}
else
{
$('.section').slideUp();
$(this).next('.section').slideToggle();
$(this).find('.arrows').attr("src","down.gif")
}
}
and then bind it like this:
$(document).ready(function(){
$('.section').hide();
$('.header').click(headerClick);
});
$('#printVers').click(function(){
if($('#formVersion').val() != "Print")
{
$('.header').unbind('click');
}
else
{
$('.header').click(headerClick);
}
});
I want to stop propagation of this div's onclick event to the document? When the user click on the "div", both alerts appear: 1) the div's alert and 2) the document's alert. I want to suppress the document alert.
I know how to do it using addEventListener, but is there another way to to do it? The problem below is that I don't know how to get ahold of the event -- I tried "event = element.onclick", shown below, but that doesn't work. How do I get the event?
<head>
<script>
function showMenu(element) {
alert("div clicked");
event = element.onclick; // HOW TO GET HOLD OF THE EVENT?
// Don't propogate the event to the document
if (event.stopPropagation) {
event.stopPropagation(); // W3C model
} else {
event.cancelBubble = true; // IE model
}
}
document.onclick = function() {
alert('document clicked');
};
</script>
</head>
<body>
<div id="foodmenu" onclick="showMenu(this);">Click inside this div</div>
or click outside the div.
</body>
Change your function definition to include the event:
function showMenu(event, element) {
alert("div clicked");
// Don't propogate the event to the document
if (event.stopPropagation) {
event.stopPropagation(); // W3C model
} else {
event.cancelBubble = true; // IE model
}
}
Then change the call to pass in the event:
div id="fooddmenu" onclick="showMenu(event, this);">Click inside this div</div>
Try EventListeners:
html:
<div id="fooddmenu">Click inside this div</div>or click outside the div.
js:
function showMenu(e) {
alert("div clicked");
}
document.onclick = function() {
alert('document clicked');
};
window.onload = function(){
document.getElementById("fooddmenu").addEventListener("click", function(e){
showMenu(this);
e.stopPropagation();
});
};
Add the onclick to the body element.
Douglas,
It does stop the event from getting bubbled up.
Check this out http://jsbin.com/ahoyi/edit
here, if you comment the alert statement, it will show 2 alerts on clicking the smaller box else only one.
Hope this helps.
well, that's a jquery code.
$("#id") same as document.getElementById("id")
.click function is same as addEvent("click", function() { ... } );
so basically both the functions there are click handlers for Parent and Child DIVs.
Observe the output by commenting / uncommenting the "return false;" statement.
Hope that helps.
By the way, sorry for that "$" confusion.
$("div").click(function(){
...
...
...
return false; //this will stop the further propagation of the event
});
Add Pointer-events: none to the particular element will help to stop pointer events.
event.StopPropagation() will help us to avoid child propagating
