After appending a button on Html document the jQuery event associated with it not working ?
For example:
$("#mydiv").append('X');//this is button appending
$("#mybutton").click(function(){
alert("hello");
});
Assuming you call the .click() method on #mybutton before it is actually appended to #mydiv, you need to use .on() as the button doesn't exist when you attach the event handler:
$('#mydiv').on('click','#mybutton',function(){
alert('hello');
});
Should work...
Why don't you set the click inside the append?
This way you wouldn't need to concern about the element being added or not to the document's flow, since you'd be setting the event callback on the actual DOM element variable:
$("#mydiv").append(
$('X').click(function() {
alert("hello");
})
);

I tried method :
Attaching click event to a JQuery object not yet added to the DOM
but seems not working in my situation. After I created dom elements by jquery, the newly created elements are not accessible. What I want is to after clicking "click me" button, and the image will show up and I hope click the image and a div (#color-picker-box) to show up.
My code: https://codepen.io/MoMoWongHK/pen/ZXbWYb
add the number sign # when calling the id of your div,
from
$("myDiv").on("click" ,".color-picker-icon" , function(){
alert("hi");
$("#color-picker-box").removeClass("display-none");
});
to
$("#myDiv").on("click" ,".color-picker-icon" , function(){
alert("hi");
$("#color-picker-box").removeClass("display-none");
});
You just missed # while using myDiv as a selector!
Wrong:
$("myDiv").cl....
Corrected:
$("#myDiv").cl.....
You need to use event Delegation since the element is not added to dom yet. You need to capture the click on its parent.
$('#myDiv').on("click", "#color-picker-box", function(e){
console.log('color box clicked');
});

I'm trying to add a some event functions to dynamically generated elements on a page.
I've used the Event delegation as follows.
//For Static Element
$(".get_flickr_image").click(function(){
getFlickrImages();
});
// For Dynamic Element
$(document).on("click", $(".get_more_flickr_image"), function(){
getFlickrImages();
});
But for some reason, the second function is called whenever I click anywhere on the document. Am I doing it wrong?
You should use
// For Dynamic Element
$(document).on("click",".get_more_flickr_image", function(){
getFlickrImages();
});
You're not passing the selector correctly.
on() does not have an overload for passing jQuery objects. Pass the selector as a string instead
$(document).on("click", ".get_more_flickr_image", function(){
getFlickrImages();
});
I have a button that is loaded into my page using ajax:
<button id="submit">Submit</button>
I am using this code on the page that the button is being loaded into:
<script type="text/javascript">
$(function() {
$("button#submit").click(function(){
alert('Submit Clicked');
});
});
</script>
Why is it not detecting the click from the ajax content?
When you attach the click event you attach it to the existent elements in the DOM, when the ajax content comes, new DOM elements are created and the event wasn't attached to them.
One option is to use events delegation a way (but not recommended) to do it is using the document to read the event
$(document).on('click', 'button#submit', function(){
//do something
});
A better way is put the delegation to the element which gets the new content, lets assume is a form with an id formElement, It would be something like
$("#formElement").on('click', 'button#submit', function(){
//do something
});
Using that event delegation the new content from ajax will fire the click event.
PD if you have an ID in a element just use the id, like #submit, It makes a faster selector than tag#id because It used getElementById internaly
In your code you have attached the event handler to buttons before the button is created. You need to attach the handler afterwards. Add the handler in the ajax success() function instead, after you have created the button, and everything will work ok.
Its because its dynamically added button.For that you have to use on() method try following
$(document).on('click', 'button#submit', function(){
alert("hi");
});

I have a simple code that check a select change and alert a message. This is working ok but when I insert new .select-payment elements on the page this method is only available to the first one and not the ones created via javascript
$(document).ready(function() {
return $(".select-payment").on("change", function() {
return alert("hello");
});
});
Any idea how to make it work for any element that is added after the page is loaded that has a .select-payment class?
$(document).on("change", ".select-payment", function() {
alert("hello");
});
Also returning from within the change handler hardly makes sense, even less, returning the result of an alert.
You could use event delegation like below,
$(document).on('change', '.select-payment', function () {..
Replace the document with any closeby container that exist in DOM when executing the above line
Event delegation binds the event to the parent element and executes the handler when event.target matches the specified selector.
When targeting dynamically created elements, you need to use .on()'s delegated syntax:
$(document).on("change", ".select-payment", function() {
From the docs:
Event handlers are bound only to the currently selected elements; they
must exist on the page at the time your code makes the call to .on().
To ensure the elements are present and can be selected, perform event
binding inside a document ready handler for elements that are in the
HTML markup on the page. If new HTML is being injected into the page,
select the elements and attach event handlers after the new HTML is
placed into the page.
why are you putting return statement ? You must attach your event handler to the document and not the existing .select-payment.
Try this : $(document).on("change",".select-payment",function(){...});
$(document).on("change", ".select-payment", function () {
alert("hello"); }
);
You can replace document with any closer parent element which will always exist in DOM for better performance. Like
$('#closestId').on("change", ".select-payment", function () {
alert("hello");
}
);
if you use $("document") jQuery will search for a node/tag named as document like and wont find anything as document is actually an object.
But you could use $("body") as body is a node/element of DOM.
I am a bit confused, I have a bunch of elements that get added via jquery using a ajax call and I want to attach a click handler to them (there could be a lot).
But I have no idea how to even begin this, I looked at .on and it is really confusing. I want to attach a click event handler for a certain class so that when I click on it, I get the this.id and then do stuff with it.
What you're trying to do is called event delegation.
You want to set the event listener on a higher element in the DOM that'll never change, but only fire off the event handler if the child element that has been clicked matches a specific selector.
Here's how it's done with jQuery's .on():
$(document).on('click', '.your-selector', function(){
alert(this.id);
});
P.S. You could probably apply the event listener to an element lower down in the DOM tree...
This will get you the id of a clicked element with the class "test"...
$(".test").on("click", function() {
var id = $(this).attr("id")
});
You'll need to run that after the ajax call returns. It will only bind the click event to elements that exist when it runs, so it's no good at document.ready.
