下面这段代码用了viewport布局，在west那块我加了个树形菜单，现在要实现单击树的节点，在center块中显示不同页面，可是用了hrefTarget好像不管用，都是新打开一个窗口，大家帮我看看哪里有问题...
<script type="text/javascript">
Ext.onReady(function(){
var root=new Ext.tree.TreeNode({
id:'root',
text:'点餐系统'});
var node1=new Ext.tree.TreeNode({text:'桌台信息维护',href:'table_list.html',hrefTarget:'mainFrame'});
var node2=new Ext.tree.TreeNode({text:'菜品信息维护',href:'vegetable_list.html',hrefTarget:'mainFrame'});
root.appendChild(node1);
root.appendChild(node2);
var tree=new Ext.tree.TreePanel({
animate:true,
rootVisible:true,
autoScroll:true,
autoHeight:true,
useArrows:true,
root:root,
autoHeight:true
});
new Ext.Viewport({
layout: 'border',
items: [
{
frame:true,
title:"点餐系统",
region:"west",
items:tree,
width:200,
collapsible:true,
split:true
},{
region:'center',
id:'mainFrame',
autoScroll:true,
collapsible: true
},{
region: 'north',
frame:true,
contentEl:headdiv,
split: true,
height: 100,
minHeight: 100
}]
});
});
</script>
