[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]

实例代码二见：

效果：

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <style type="text/css"> #test{width:200px; height:200px; background:pink; cursor:move; position:absolute; left:100px; top:100px} </style>

实例代码三见（拖动把柄）：

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <style type="text/css"> *{margin:0;padding:0} #testBox{ width:300px; height:300px; background:red; position:absolute; left:0; top:0} #test{width:200px; height:200px; background:pink; cursor:move; margin:30px} </style> <div id="testBox"> <div id="test">在这里才能移动</div> </div>
