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="0" src="@Url.Content("~/System/MachineConfig")" nodeId="00302" style="width: 100%; height: 750px" name="i" id="urlIframe"
        frameborder="0" 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[0] + ',' + da[1] + '&RowId=' + da[0] + '&m_name=' + da[1] + "' 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=") > -1) {
                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(1);

            var pairs = query.split("?"); // Break at ampersand 
            for (var i = 0; i < pairs.length; i++) {
                var pos = pairs[i].indexOf('=');
                if (pos == -1) continue;
                var argname = pairs[i].substring(0, pos);
                var value = pairs[i].substring(pos + 1);
                value = decodeURIComponent(value);
                args[argname] = value;
            }
            return args[strParame];
        }
