2、刚开始的页面效果如下图，是一个只有north,center区域的easyUI easyui-layout布局，单击“打开”按钮，会在center区域再嵌套一个easyUI的布局

3、单击“打开”按钮页面效果如下图所示

4、单击“获取”按钮，获取到嵌套的easyUI中id为pageDetail的iframe

5、主要HTML代码

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
    <link href="Easyui/themes/default/easyui.css" rel="stylesheet" />
    <link href="Easyui/themes/icon.css" rel="stylesheet" />
    <script src="Easyui/jquery-1.7.2.min.js" type="text/javascript"></script>
    <script src="Easyui/jquery.easyui.min.js"></script>
    <script src="Easyui/locale/easyui-lang-zh_CN.js"></script>
    <script src="JS/jquery.cookie.js"></script>
    <script src="JS/sysUtil.js"></script>
    <script type="text/javascript">
        $(function () {
            $('#btnDK').on('click', function () {
                $("#pageUrl").attr("src", "pageDetailInfo.aspx");
            });
            $('#btnHQ').on('click', function () {
                $("#pageUrl").contents().find('#pageDetail').attr("src", "HQInfo.aspx");
                var width1 =  $("#pageUrl").contents().find('#layout2').layout('panel','west').panel('options').width;                
            });
        });
    </script>
</head>
<body id="layoutone" class="easyui-layout">
   <div data-options="region:'north',split:true,title:'north'" style="100%;height:150px;">
    <input type="button" id="btnDK" value="打开" /> &nbsp;&nbsp;&nbsp;<input type="button" id="btnHQ" value="获取" />
   </div>
    <div data-options="region:'center',title:'center'">
        <iframe id="pageUrl" style="border:none;100%;height:100%;" ></iframe>
    </div>
</body>
</html>

6、pageDetailInfo.aspx代码如下

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
    <link href="Easyui/themes/default/easyui.css" rel="stylesheet" />
    <link href="Easyui/themes/icon.css" rel="stylesheet" />
    <script src="Easyui/jquery-1.7.2.min.js" type="text/javascript"></script>
    <script src="Easyui/jquery.easyui.min.js"></script>
    <script src="Easyui/locale/easyui-lang-zh_CN.js"></script>
</head>
<body id="layout2" class="easyui-layout">
 <div data-options="region:'west',title:'west',split:true" style="300px;">
      <iframe id="pageDetail" style="border:none;100%;height:100%;" ></iframe>
 </div>
    <div data-options="region:'center',title:'center'">345435</div>
</body>
</html>

7、HQInfo.aspx代码如下

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    获取成功

    </form>
</body>
</html>
