jQuery淡出事件监听器

Question

I have an existing self coded accordian that i now need to attach an event listener to an existing fadeout event. Can I bind a new fadout listener to an existing one? And how is this done? Here is the accordian ia jsFiddle

Answer 1

As others have said there isnt a fadeout event - you could create your own event though - you would add it to the callback for fadeout :

$(currentSlide).fadeOut("normal", function () {
    // your other code
    $(this).trigger('myFadeOutEvent');
});    

then you would need to listen for the event

 $('.class').on('myFadeOutEvent',function() {
    // do something
 });

See the docs for .trigger() for details

Answer 2

FadeOut does not have an even listener. However, it has a callback, a function that fires after the fadeout is finished. The downside with this is that you will have to specify what should happen every time you use fadeout.

This has caused miles of code for me earlier.

$('.element').fadeOut(400,function () {
    //Whatever you want to do after the fade
});

Answer 3

您可以将函数绑定到要侦听的该元素上，然后进行淡出调用，将要用作回调函数的操作

Answer 4

Refer to the doc http://api.jquery.com/fadeOut/

It says about 2 syntaxes .fadeOut( [duration] [, callback] ) and .fadeOut( [duration] [, easing] [, callback] )

You can apply any callback function
