EXT Tree叶子节点的ID如何存储到Store的HttpProxy参数中？

Question

我想通过treePanel中的叶子节点打开TabPanel中的Grid，但是后台一直没法得到叶子节点的值
代码如下：
[code="java"]
var ggid;

var store = new Ext.data.Store({
proxy:new Ext.data.HttpProxy({url:'requHandler.htm?m=findRequs&gid='+ggid,method:'GET'}),//这里的ggid在后台一直拿不到 undefined.
reader: new Ext.data.JsonReader({
root: 'objectList',
totalProperty: 'total',
//id: 'threadid',
fields: [
'name', 'coverstatus', 'priority'
]
}),
sortInfo: {
field: 'name',
direction: 'desc'
}
});

var treeTR = new Ext.tree.TreePanel({
    title: 'Test',
    border: false,
    iconCls: 'settings',
    layout:"fit",
    autoScroll:true,
    animate:false,
    enableDD:false,
    rootVisible:false,
    border:false,
    listeners: {  
       'dblclick':function(node,e){  
         if(node.isLeaf()){
             ggid=node.id;//这里我把叶子节点的id存下来了

         tabs.add({
       title: 'Requirment' ,
               iconCls: 'tabs',
               autoScroll:true,
            closable:true,
            items: [gridRequ]  //gridRequ是我gridPanel,store:store
         }).show();
          alert(ggid);//这里也能显示
         store.load({params:{start:0,limited:10}});  
         }
       }  
    } 
});

[/code]
我在页面上设置个变量也无法存储 node.id 该如何解决呢

你应该是要把
var store = new Ext.data.Store({

proxy:new Ext.data.HttpProxy({url:'requHandler.htm?m=findRequs&gid='+ggid,method:'GET'}),//这里的ggid在后台一直拿不到 undefined.

reader: new Ext.data.JsonReader({

root: 'objectList',

totalProperty: 'total',

//id: 'threadid',

fields: [

'name', 'coverstatus', 'priority'

]

}),

sortInfo: {

field: 'name',

direction: 'desc'

}

});

放在
'dblclick':function(node,e){

if(node.isLeaf()){

ggid=node.id;//这里我把叶子节点的id存下来了

         tabs.add({   
       title: 'Requirment' ,   
               iconCls: 'tabs',   
               autoScroll:true,   
            closable:true,   
            items: [gridRequ]  //gridRequ是我gridPanel,store:store   
         }).show();   
          alert(ggid);//这里也能显示   

[color=red]//把store的赋值放在这个地方[/color]
store.load({params:{start:0,limited:10}});

}

}
