$( document ).ready(function() {
$('#handler').on('click', '.selector', function(){
alert( $(this).text());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="handler">
handler content
selector content
</div>
How do I get the #handler inside the on method without explicitly specifying it?
Use the event "delegateTarget" property
$( document ).ready(function() {
$('#handler').on('click', '.selector', function(e){
console.log(e.delegateTarget);
});
});
Working example:-
$( document ).ready(function() {
$('#handler').on('click', '.selector', function(e){
console.log(e.delegateTarget);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="handler">
handler content
child
<div>
grand child
</div>
<div>
<div>
great grand child
</div>
</div>
</div>
In this specific case you can directly use the unique id you have
$("#handler").
In case if that is a class, you have $(this).parent() to the top level.
you can chain it to nth level , till you reach the top. $(this).parent().parent()...
or since you know the selector, you can do $(this).parents("selector")
Use closest() if the parent has hierarchy,
$(this).closest('div')
and use parent() if it is direct parent of target element,
$(this).parent('div');
And the selector is unique and has id like handler then the best option is
$('#handler')
Change it to
$( document ).ready(function() {
$('#handler').on('click', function(){
//$(this) here will be #handler.
});
});
Or if you still want the function to fire when someone clicks on .selector then you can do the following
$( document ).ready(function() {
$('#handler').on('click', '.selector', function(){
var handler = $(this).parent();
});
});

I want to trigger something when I click on a certain class within a div.
I tried this
$("div .event").click(function() {
alert($( this ).text());
});
And
$("div").on("click", $('.event'), function() {
alert($( this ).text());
});
//Or
$(".SimpleCalendar .event").click(function() {
alert($( this ).text());
});
//I do not even know what this is supposed to do ...
$(".SimpleCalendar tbody tr td div .event").click(function() {
alert($( this ).text());
});
And many more but still can not figure out why this is not working
My HTML is the following :
The div that you're selecting is the one that has the class .event, not a descendant of it. Therefore the correct selector is div.event. Try this:
$("div.event").click(function() {
alert($( this ).text());
});
Or just:
//Warning: if elements unlike the div also have the event class then stick to
//the above as the selector is more specific
$(".event").click(function() {
alert($( this ).text());
});
And don't forget that each of these options should be in DOM ready like so:
$(function() {
$("div.event").click(function() {
alert($( this ).text());
});
});
You were making use of parent descendent selector, since event class is on the div itself and not its descendent your selector was incorrect.
One of these should work for you
Try this
$("div.event").click(function() {
alert($( this ).text());
});
or,
$(".SimpleCalendar").on("click", '.event', function() {
alert($( this ).text());
});

I want to change the ID of an element (a <div>) using jQuery. Below is an example of my JavaScript, CSS and HTML. Right now, when I click the <div>, nothing happens.
$( ".pre_div" ).click(function() {
$( ".pre_div" ).attr('id','after_div');
});
$( ".after_div" ).click(function() {
$( ".after_div" ).attr('id','pre_div');
});
#pre_div {width:20px;height:20px;background-color:red;cursor:pointer;}
#after_div{width:20px;height:20px;background-color:blue;cursor:pointer;}
<div id="pre_div">:-)</div>
. is for classes and # is for ids, plus you have to use the .on() function, otherwise it will not work
$(document).on('click','#pre_div',function() {
$(this).attr('id','after_div');
});
$(document).on('click','#after_div',function() {
$(this).attr('id','pre_div');
});
JSFIDDLE DEMO
You should use # – id selector – instead of . – class selector (also, you can use this to access element within it's event listener):
$( "#pre_div" ).click(function() {
$(this).attr('id','after_div');
});
$( "#after_div" ).click(function() {
$(this).attr('id','pre_div');
});
JSFiddle
Please use $(this) to refer to the clicked item otherwise you may give many item the same id. However, with this approach, you are still assiging the same id to each clicked div, which is not good. How about adding the index of the clicked div to make it a unique id:
$(".pre_div").click(function() { //any div with pre_div class
$(this).attr('id'+ $(this).index(),'after_div');
});
$(".after_div").click(function() { //any div with after_div class
$(this).attr('id'+ $(this).index(),'pre_div');
});
"pre_div" and "after_div" are not classes, they are id's of your div
Should access it like this way.
$( "#pre_div" ).click(function() {
$( "#pre_div" ).attr('id','after_div');
});
$( "#after_div" ).click(function() {
$( "#after_div" ).attr('id','pre_div');
});
I'm trying to select a div for a click event but not the inputs within said div. I thought this would do it but it does not work. here is a demo. Thank you
html
<div id = "test"><input></div>
js
$('#test:not(input)').click(function(){
alert();
});
You could check to see if the clicked element is an input element using !$(e.target).is('input')
Updated Example
$('#test').on('click', function (e) {
var $target = $(e.target);
if (!$target.is('input')) {
alert('clicked');
}
});
When you click on the input, the click event bubbles to the div above it.
You can stop this by calling stopPropagation or stopImmediatePropagation on the event object.
http://jsfiddle.net/t66f06oL/1/
$( '#test' ).on( 'click', function() {
alert();
} );
$( '#test' ).on( 'click', 'input', function( e ) {
e.stopImmediatePropagation();
} );
When you click on the input control your click event is actually caught by the parent div. You can fix this by changing your code to this:
$('#test:not(input)').click(function(){
alert();
});
$('#test').find('input').click(function(e){
e.stopPropagation();
});
I have a <div id="myContainer"></div> .
I also have a button: <input type="button" value="Send" id="sendButton">
While clicking at the button: it replaces the DIV with another:
$( "#sendButton" ).click(function() {
$( "#myContainer" ).replaceWith("<div id='calc'><input type=\"text\" id=\"screen\" value=0><button id=\"add\">+</button><button id=\"mul\">*</button><button id=\"settings\">settings</button><button id=\"clear\">clear</button></div>");
});
I want to activate another function after click on a new button I've just put (<button id=\"mul\">*</button>):
$( "#mul" ).click(function() {
console.log(' mul clicked!');
});
Which doesn't work, the fact that I'm waiting for a click on a div that just created have something to do with it?
You need to attach event to #mul. Because it is appended dynamically, $("#mul").click() will not work.
.on() attaches event handlers to the currently selected set of elements.
Try:
$("body").on("click","#mul",function(){
console.log("mul clicked!");
});
More information here.
When you call $( "#mul" ).click(), you're attaching an event handler to #mul as it exists at that point. To fix this, just call $( "#mul" ).click() after you create #mul.
$( "#sendButton" ).click(function() {
$( "#myContainer" ).replaceWith("<div id='calc'><input type=\"text\" id=\"screen\" value=0><button id=\"add\">+</button><button id=\"mul\">*</button><button id=\"settings\">settings</button><button id=\"clear\">clear</button></div>");
$( "#mul" ).click(function() {
console.log( ' mul clicked!' );
});
});
You could also use jQuery's .on method with the optional selector, called a delegated event handler according to the documentation. Take a look at the API for jQuery if that's what you want: jQuery API documentation. The basic usage would be something like
$( document ).on( "click", "#mul", function( ) {
console.log( ' mul clicked!' );
});
use this
$(document).on("click","#mul",function() {
instead of
$( "#mul" ).click(function() {
or
$( "#sendButton" ).click(function() {
$( "#myContainer" ).replaceWith("<div id='calc'><input type=\"text\" id=\"screen\" value=0><button id=\"add\">+</button><button id=\"mul\">*</button><button id=\"settings\">settings</button><button id=\"clear\">clear</button></div>");
$( "#mul" ).click(function() {
console.log(' mul clicked!');
});
});
$( "#sendButton" ).click(function() {
$( "#myContainer" ).replaceWith("<div id='calc'><input type=\"text\" id=\"screen\" value=0><button id=\"add\">+</button><button id=\"mul\">*</button><button id=\"settings\">settings</button><button id=\"clear\">clear</button></div>");
// add listener here
$( "#mul" ).click(function() {
console.log(' mul clicked!');
});
$( "#mul" ).trigger("click"); // add this to your code
});
http://api.jquery.com/trigger/ see detail of trigger()
http://jsfiddle.net/tnnj5/ here is a demo
you must add listener after the new content has insert into dom
You can use .live() method to bind event with dynamically added content.
Try this:
$("#mul").live("click", function() {
console.log(' mul clicked!');
});
Try in fiddle
You can also use jquery .on(), But here you add dynamic content. So you need to use event delegation to register the event handler like:
$(document).on("click","body #mul", function() {
console.log(' mul clicked!');
});
Try in jsfiddle with on
I have index.php and will load index-edit.php with a button click into index.php in a <div class="edit-wrapper"> </div>. I have some input in index.php and some input in index-edit.php. I want to add .active class to them on focus out, but jQuery does not add .active class to the ones in index-edit.php, but rest of them (which are not index-edit.php) works fine.
Look at my script.js.
$( input ).focusout( function() {
$( this ).addClass('active');
});
$( document ).on( "click", ".btn", function() {
$('.edit-wrapper').load('index-edit.php');
});
Since the inputs are added dynamically, you need to use event delegation to register the event handler
// New way (jQuery 1.7+) - .on(events, selector, handler)
$(document).on('focusout', 'input', function(event) {
$(this).addClass('active');
});
Where are you loading script.js ? Try this :
$(document).ready(function(){
$( input ).focusout( function() {
$( this ).addClass('active');
});
$( document ).on( "click", ".btn", function() {
$('.edit-wrapper').load('index-edit.php');
});
});
need to use event delegation
$( document).on('focusout', 'input ', function() {
$( this ).addClass('active');
});
