我怎么才能跳到"Backstage/test"这里呀？

Question

<script>
BUI.use('common/main',function(){
var config = [{id:'1',menu:[{text:'用户管理',items:[{id:'12',text:'测试',
href:'{:U("Backstage/test")}'},
{id:'3',text:'角色管理',href:'Role/index.html'},{id:'4',text:'用户管理',href:'User/index.html'},{id:'6',text:'菜单管理',href:'Menu/index.html'}]}]}];
new PageUtil.MainPage({
modulesConfig : config
});
});
</script>
其中，href:'{:U("Backstage/test")}'}这一句提示：
非法操作:{:U("Backstage

Answer 1

将href:'{:U("Backstage/test")}'修改为href:{:U("Backstage/test")}
