jQuery获得页面元素的绝对/相对位置即绝对X,Y坐标

获取页面某一元素的绝对X,Y坐标，可以用offset()方法：

复制代码 代码如下:

<span>var</span> X <span>=</span> $<span>(</span><span>'#DivID'</span><span>)</span>.<span>offset</span><span>(</span><span>)</span>.<span>top</span><span>;</span>
<span>var</span> Y <span>=</span> $<span>(</span><span>'#DivID'</span><span>)</span>.<span>offset</span><span>(</span><span>)</span>.<span>left</span><span>;</span>

复制代码 代码如下:

<span>var</span> X <span>=</span> $<span>(</span><span>'#DivID'</span><span>)</span>.<span>position</span><span>(</span><span>)</span>.<span>top</span><span>;</span>
<span>var</span> Y <span>=</span> $<span>(</span><span>'#DivID'</span><span>)</span>.<span>position</span><span>(</span><span>)</span>.<span>left</span><span>;</span>
