jQuery: Getting px position of an element in Integer format

问题

This code works in FF, but not in IE:

parseInt($('.scroller').css('left');

In FF it returns 0px;

In IE it returns NaN.

What's a good way to get a pixel position of an element?

<div class="holder">
    <div class="scroller">
    </div>
</div>

回答1:

Use offset:

$('.scroller').offset().left;

offset() returns an object containing the properties left and top, which are the position values relative to the document in pixels.

If you want the position relative to the parent element, use position instead.

回答2:

It would be however always relative to document, therefore position() (relative to parent, i.e. holder) would sometimes be rather accurate and sometimes none of them.
