jQuery - 在ul中获取li的position（）

Question

I'm trying to figure out how to get the left position of the li relative to its ul parent tag. Any idea?

Answer 1

You can make the ul tag the li 's offset parent by giving it position: relative . This will allow you to call position on the li , which will tell you what you want to know.

var pos = $("#target").position();
$("#target").text("This li is positioned " + pos.top
                + "px from the top and " + pos.left
                + "px from the left edge of the ul");

See it in action .

Answer 2

比较.offset()的的li与.offset()的的ul或.parent()

Answer 3

It should be possible to get this using jQuery's .position().

$('li').position()
