on() doesn't recognize a class [duplicate]

Event binding on dynamically created elements?
(23 answers)
Closed 6 years ago.
I am facing a problem with on(). Here is my code:
<span class="add" id="id_foo" >add this stuff</span>
$(".add").on('click', function() {
$.post("/toto.com/add.php", { trainning: this.id }, function() {});
$(this).html("Remove this stuff");
$(this).removeClass("add").addClass("remove");
//alert($(this).attr("class"));-->give the good class
});
$(".remove").on('click', function() {
//doesn't work
$.post("/toto.com/remove.php", { trainning: this.id }, function() {});
$(this).html("add this stuff");
$(this).removeClass("remove").addClass("add");
});
The selector for the class remove doesn't recognize it whereas when I click on the button with the add class, the class is changing. Do you know what the problem is?
Thank you for your help!

You need to use delegated event handlers as you're dynamically changing the classes the handlers are attached to. Try this:
$(document).on('click', ".add", function() {
$.post("/toto.com/add.php", { trainning: this.id });
$(this).html("Remove this stuff").toggleClass("add remove");
});
$(document).on('click', ".remove", function() {
$.post("/toto.com/remove.php", { trainning: this.id });
$(this).html("add this stuff").toggleClass("remove add");
});
Depending on the location of the script tag this JS code is in you may also need to wrap your code in a document.ready handler. If it's just before the </body> tag it will work fine, if it's in the head, place it inside $(function() { /* your code here */ });

Add/Remove classes not working for some reason [duplicate]

var vaStyle = $("nav.global_nav, .rsGCaption .intro-caption");
var vid_detach = $("div.rsCloseVideoBtn");
var vid_launch = $("h1#vidLaunch");
vid_launch.click(function () {
vaStyle.addClass("hprs-video-active");
});
vid_detach.click(function(){
vaStyle.removeClass("hprs-video-active");
});
Why isn't my removeClass working? Is there a better method?
Also, when you declare a var does it work document-wide?

Sounds like your elements are getting added dynamically. Use event delegation for solving this. I made changes to the event binding.
var vaStyle = $("nav.global_nav, .rsGCaption .intro-caption");
var vid_detach = "div.rsCloseVideoBtn";
var vid_launch = "h1#vidLaunch";
$(document).on('click', vid_launch, function () {
vaStyle.addClass("hprs-video-active");
});
$(document).on('click', vid_detach, function () {
vaStyle.removeClass("hprs-video-active");
});

Jquery appended item click function not working [duplicate]

Ok so I have a button that when someone clicks it appends some info to a section.
like so:
function() {
$(".blend-tile").click(function() {
$(this).hide();
var li = $('<li><div class="align-table"><div class="color-img t-align"></div><div class="t-align"><div class="infora"></div><div class="percent-mix"></div><div class="mix-value"></div></div></div><div class="clear-tile">X</div></li>');
$('#mixers').append(li);
$('.tpic', this).clone(true, true).contents().appendTo(li.find('.color-img'));
$('.infora', this).clone(true, true).contents().appendTo(li.find('.infora'));
if ($('#mixers li').length === 6) {
$(".tiles").hide();
$(".nomore").show();
}
});
});
Which is all good work's fine.
But I also want all of this to remove() when I click <div class="clear-tile">X</div>.
and for that I am using:
$(function() {
$(".clear-tile").click(function() {
$(this).parent().remove();
});
});
But nothing happens no error nothing.
I also have similar function's in my file that use remove() and such which work fine. It's just anything that I try to trigger from .clear-tile just doesn't work at all.
I have a feeling it's down to me appending it but I'm not sure any help would be much appreciated

You need to use event delegation:
$("#mixers").on("click", ".clear-tile", function() {
$(this).parent().remove();
});
Instead:
$(".clear-tile").click(function() {
$(this).parent().remove();
});

jquery click elsewhere function [duplicate]

How do I detect a click outside an element?

I'm trying to remove the css when somewhere on the page has been clicked. I know how to implement the css changes but can't figure out how to or where to place the listener for a mouse click.
Any suggestions would be great.
$(document).ready(function() {
var friends = false;
$('#friends').click(function() {
friends = true;
$('#cont').css({'left':'502px'});
$('#members').css({'left':'251px','display':'inline','opacity':'1'});
alert(friends);
});
if($(document).click() && friends){
alert('here');
};
});

Got it working eventually using this but modified it alot:
jQuery().ready(function(){
$('#nav').click(function (event) {
$(this).addClass('activ');
event.stopPropagation();
});
$('html').click(function () {
if( $('#nav').hasClass('activ') ){
$('#nav').removeClass('activ');
}
});
});

Dynamic click event for buttons [duplicate]

Jquery dynamic button : how to bind to exisitng click event by class
(2 answers)
Closed 9 years ago.
I have a button which calls a function via data-bind and generates a new button.
self.submitNewPopUp = function(data, event) {
var butnId = event.srcElement.form.id.replace('style-', '');
var styleButton = $('<input/>').attr({type: 'button', value: data.styleData, id: butnId});
styleButton.onclick = function() {
alert("blabla");
};
$("#showButtons").append(styleButton);
$('#' + event.srcElement.form.id).hide();
};
But the new button has no click event. How to do it?

You'd assign a click event listener to an ancestor of the button using jQuery's on() method. For instance, if your markup was:
<div id="showButtons">
<input type="button" />
</div>
You'd use:
$('#showButtons').on('click', 'input[type=button]', function() { ... });

styleButton button is a jQuery object, not a dom element so it does not have a onclick property. You need to use the click(function(){}) event registration method to register the event handler
styleButton.click(function() {
alert("blabla");
});

Use jquery.on() for the dynamic created elements
$("#div").on("click", "button", function(event){
alert($(this).text());
});
