Jquery Remove All Event Handlers Inside Element

Question

I have a div element with several elements inside it like buttons and so forth which have event handlers attached to them. I know its possible to go:

$("#button1").off()

To remove the handler for a button but I would like to do something like this if possible:

$("#div1").removeChildHandlers();

Is there a native function in JQuery to do this or would I have to loop them all the elements and remove 1 by 1?

Storey

is maybe .find('button').off() what are you looking for? – Attorn

Nope something less specific – Storey

Answer 1

jQuery will do the looping for you for just the direct children:

$("#div1").children().off();

or if you want all descendants:

$("#div1").find("*").off();

Thanks I think that covered just about all possibilities I was looking for. – Storey

Thanks for this. I found it's hard to determine whether an event handler already exists without manually tracking it. Turning all the descendant handlers off allows me to just re-apply them right after. Likely not good for performance, but a quick solution is great to have! – Tsana

what is the main difference between $("#div1").children().off() from $("#div1").off()? – Tormentor

@Malky.Kid - $("#div1").off() removes event handlers from only the #div1 element itself. $("#div1").children().off() operates on only the children of #div and does not operate on #div at all. So, it depends upon which elements you want to operate on. – Maun

@Maun my gratitude – Tormentor

Answer 2

Does this help:

$("#div1").find('*').off();

Edyth

Instead of $("#div1").find('*') one can use CSS selector $("#div1 *"). – Atmosphere

Answer 3

Try with

$("#div1 >* ").off();

Or:

$("#div1").find('button').off();

if you're talking about <button> elements

IMHO the better practice and better performant option would be to attach the handler to the outside parent with the on method...

$("#div1").find("click", ".childButton", magicFunction);

Then to remove all listeners you can call off on just the parent element.

$("#div1").off();
