Attaching click event to a JQuery object not yet added to the DOM [duplicate]

People also ask

Which method is used to bind a callback method for an event for DOM elements added at runtime?

You can use the live() method to bind elements (even newly created ones) to events and handlers, like the onclick event.

How do you add an event handler to a dynamic button?

To attach event handlers to the dynamically created button, we need to select the button with a class of btn and add an event listener of click . We're saying that onclick of the button, the p tag with a class of moreInfo should display block .

How do you add an event dynamic to an element?

Attaching the event dynamicallyclassName = 'dynamic-link'; // Class name li. innerHTML = dynamicValue; // Text inside $('#links'). appendChild(li); // Append it li. onclick = dynamicEvent; // Attach the event!


Use this. You can replace body with any parent element that exists on dom ready

$('body').on('click', '#my-button', function () {
     console.log("yeahhhh!!! but this doesn't work for me :(");
});

Look here http://api.jquery.com/on/ for more info on how to use on() as it replaces live() as of 1.7+.

Below lists which version you should be using

$(selector).live(events, data, handler); // jQuery 1.3+

$(document).delegate(selector, events, data, handler); // jQuery 1.4.3+

$(document).on(events, selector, data, handler); // jQuery 1.7+


I am really surprised that no one has posted this yet

$(document).on('click','#my-butt', function(){
   console.log('document is always there');
}) 

If you are unsure about what elements are going to be on that page at that time just attach it to document.

Note: this is sub-optimal from performance perspective - to get maximum speed one should try to attach to the nearest parent of element that is going to be inserted.


Try this.... Replace body with parent selector

$('body').on('click', '#my-button', function () {
    console.log("yeahhhh!!! but this doesn't work for me :(");
});

Try:

$('body').on({
    hover: function() {
        console.log("yeahhhh!!! but this doesn't work for me :(");
    },
    click: function() {
        console.log("yeahhhh!!! but this doesn't work for me :(");
    }
},'#my-button');

jsfiddle example.

When using .on() and binding to a dynamic element, you need to refer to an element that already exists on the page (like body in the example). If you can use a more specific element that would improve performance.

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. Or, use delegated events to attach an event handler, as described next.

You have to append it. Create the element with:

var $div = $("<div>my div</div>");
$div.click(function(){alert("clicked")})
return $div;

Then if you append it will work.

Take a look at your example here and a simple version here.


Complement of information for those people who use .on() to listen to events bound on inputs inside lately loaded table cells; I managed to bind event handlers to such table cells by using delegate(), but .on() wouldn't work.

I bound the table id to .delegate() and used a selector that describes the inputs.

e.g.

HTML

<table id="#mytable">
  <!-- These three lines below were loaded post-DOM creation time, using a live callback for example -->
  <tr><td><input name="qty_001" /></td></tr>
  <tr><td><input name="qty_002" /></td></tr>
  <tr><td><input name="qty_003" /></td></tr>
</table>

jQuery

$('#mytable').delegate('click', 'name^=["qty_"]', function() {
    console.log("you clicked cell #" . $(this).attr("name"));
});
