返回值:Object
{top,left}position()
V1.2概述
获取匹配元素相对父元素的偏移。
返回的对象包含两个整型属性：top 和 left。为精确计算结果，请在补白、边框和填充属性上使用像素单位。此方法只对可见元素有效。
示例
描述:
获取第一段的偏移
HTML 代码:
<p>Hello</p><p>2nd Paragraph</p>
jQuery 代码:
var p = $("p:first");
var position = p.position();
$("p:last").html( "left: " + position.left + ", top: " + position.top );结果:
<p>Hello</p><p>left: 15, top: 15</p>
