js中iframe的用法

最近遇到的项目总是习惯左边一个树，点击每个树的节点右边出现相应的信息，遇到这种情况用iframe还是很简单的，

例如 ： 页面文件

 @section Tree{
     <ul id="tree">
     </ul>

 }
 @section Search
 {
 }
 <input id="clickassets" type="hidden" value="@ViewBag.url" />
 <div class="g_tgCenterGrid" data-options="region:'center',border:1" id="dvGrid">
     <iframe marginwidth="" src="@Url.Content("~/System/MachineConfig")" nodeId="" style="width: 100%; height: 750px" name="i" id="urlIframe"
         frameborder="" scrolling="no"></iframe>
 </div>

js文件

    $.ajax({
                     dataType: "text",
                     url: TY.Root + "System/MachineConfigInfo?RowId=" + nodeid + "&m_name=" + noidtext,
                     type: "post",
                     success: function (result) {

                         if (result != null && result != "") {
                             var da = result.split(",");
                             var me = this;
                             $("#dvGrid").html("<iframe marginwidth='0' src='MachineConfig?nodeId=" + da[] + ',' + da[] + '&RowId=' + da[] + '&m_name=' + da[] + "' style='width: 100%; height: 750px' name='i' id='urlIframe' frameborder='0' scrolling='no'></iframe>");

                         }
                     }

                 });

传递到该页面后，接收iframe传递过来的参数

       if (location.href.indexOf("?nodeId=") > -) {
                 var ids = request('nodeId');
                 var da = ids.split(",");
                      }

 //获取url的参数
         function request(strParame) {
             var args = new Object();
             var query = location.search.substring();

             var pairs = query.split("?"); // Break at ampersand
             for (var i = ; i < pairs.length; i++) {
                 var pos = pairs[i].indexOf('=');
                 if (pos == -) continue;
                 var argname = pairs[i].substring(, pos);
                 var value = pairs[i].substring(pos + );
                 value = decodeURIComponent(value);
                 args[argname] = value;
             }
             return args[strParame];
         }
