dom元素的jQuery索引？

Question

I have...

element = document.elementFromPoint(x, y)

then I want to do something like...

index = $(element).index()

The DOM element is a li and I need its position in the list.

Thanks!

EDIT: If what i'm doing is correct then something here is wrong, Touch events over two dom elements?

Any help is much appreciated.

Answer 1

$(element) will work, if you want to know its position you need to select it's preceding siblings.

jQuery than gives you the length property, wich works like on arrays.

$(element).prevAll().length;

Answer 2

What you want is $('li').index(element);

index() ^docs allows you to pass a selector or DOM element as a parameter to work similarly to indexOf .

Answer 3

这适用： index = $(element).index()
