ExtJs的一个问题

Question

Ext.onReady(function(){
var DivItems = ""
var MenuItems = ""
//**************************************************************
//就是这里 用MenuItems.asp输出的就是下面两行的东西,但是就是不行
// $.getScript("/MenuItems.asp")
MenuItems={contentEl:'DBManage',title:'DBManage',border:false,iconCls:'nav'};
DivItems="<div id='DBManage'>111</div>"
//**************************************************************
$("body").html(DivItems)
Ext.state.Manager.setProvider(new Ext.state.CookieProvider());  
var viewport = new Ext.Viewport({
        layout:'border',
        items:[{
                region:'east',
                title: 'East Side',
                collapsible: true,
                split:true,
                width: 225,
                minSize: 175,
                maxSize: 400,
                layout:'fit',
                margins:'0 5 0 0',
                items:
                    new Ext.Panel({
                        border:false,
                        html:"123"
                    })
             },{
                region:'west',
                id:'west-panel',
                title:'West',
                split:true,
                width: 200,
                minSize: 175,
                maxSize: 400,
                collapsible: true,
                margins:'0 0 0 5',
                layout:'accordion',
                layoutConfig:{
                    animate:true
                },
                items: [MenuItems]
            },
            new Ext.TabPanel({
                region:'center',
                deferredRender:false,
                activeTab:0,
                items:[{
                    title: 'Close Me',
                    closable:false,
                    autoScroll:true,
                    html:'123'
                }]
            })
         ]
    });
});
直接把
       MenuItems={contentEl:'DBManage',title:'DBManage',border:false,iconCls:'nav'};
       DivItems="<div id='DBManage'>111</div>"
写在里面就没有问题
但是想说用jQuery的方法去读取这样就不行了?
哪位对EXT比较熟悉的高手指点下吧

Answer 1

不行就用其他方法替换，没必要非得这样
1、用ext做ajax请求，然后用eval()来生产这两个对象
2、在cs文件中直接拼装一段js，js直接包含那两个对象，页面顶部<%=js对象%>

Answer 2

后台输出：
MenuItems=eval([{contentEl:'DBManage',title:'DBManage',border:false,iconCls:'nav'}]);
前台js
                region:'west',
                id:'west-panel',
                title:'West',
                split:true,
                width: 200,
                minSize: 175,
                maxSize: 400,
                collapsible: true,
                margins:'0 0 0 5',
                layout:'accordion',
                layoutConfig:{
                    animate:true
                },
                items: MenuItems
如果是后台输出的，前台items里的必须是json对象，所以必须用eval转义。
