如何在 Jquery 中的 event.currentTarget 中选择/查找元素？

Question

I'm using this:

$('.sizeChart').on('vclick', '.entry .ui-btn', function(e){

        console.log( e )
        console.log( e.currentTarget )
        console.log( $( e.currentTarget )
        console.log( $( e.currentTarget ).find('input.qtyInput') )

    var qty = $( e.currentTarget ).find('input.qtyInput');
    // do something

 });

Which works, but $( e.currentTarget ).find(...) seems awkward to me.

I can't bind directly to the input because this binding will go dead on iOS3+4 after a couple of clicks. Binding to the closest ui-btn works throughout.

Question:
Is there a better/easier/faster way to do the binding than what I'm using ?

Answer 1

You can just use this instead of e.currentTarget :

$(this).find(...);

Proof that event.currentTarget and this are the same.

Also the documentation says:

This property will typically be equal to the this of the function.

That's about it. It is pretty common to pass a DOM element directly to jQuery and use DOM traversal methods on it.
