使用jquery获取div的底值

Question

<div id="xx" style="bottom:20px;"></div>

我如何获得#xx的底值

Answer 1

You may use

document.getElementById('xx').style.bottom;

You'll get the string '20px' .

If you want it as a number, you'll have to parse it :

var nb = parseInt(document.getElementById('xx').style.bottom, 10);

Answer 2

在 jQuery 中：

$('#xx').css('bottom');
