treepanel getChecked问题

Question

[code="java"]
这是树的代码 我想用下面的代码来获得选中的id
var b = Ext.tree.getChecked();
var check = new Array();
for (var i = 0; i < b.length; i++) {
check.push(b[i].id);

}

for (var i = 0; i < check.length; i++) {
Ext.DomHelper.append('form1',{tag:'input',name:'checks',type:'hidden',value:check[i]})
}
//把获得的id通过form提交到action 上面这些代码 应该放到什么地方？
Ext.onReady(function() {
Ext.BLANK_IMAGE_URL = "/dtjcsy/pages/js/ext/resources/images/default/s.gif";
var Tree= Ext.tree;
var form =Ext.get('form1');

var loader = new Ext.tree.TreeLoader;
var tree = new Tree.TreePanel({
    el:'tree-div',

    autoScroll:true,
    animate:true,
    enableDD:true,
    frame:false,
    border:false,
    useArrows:true,
    checkModel:'cascade',
    onlyLeafCheckable:false,
    rootVisible:true,

    bodyStyle:'background-color:#b4d5f5',
    containerScroll: true,
    loader: new Tree.TreeLoader({
        dataUrl:'rightAction.action',
        baseParams:{roleId:2},
        baseAttrs: { uiProvider: Ext.ux.TreeCheckNodeUI }
    }),listeners:{
        load:function(loader,node,response){

        },
        checkchange:function(node,checked){

        }

    }

});

var root =new Tree.AsyncTreeNode({
    text:"可用权限列表",
    draggable:false,
    id:'0'
});

tree.setRootNode(root);
tree.render();
root.expand(true);

});

哦，有点问题，把[code="java"]form.submit = function() { [/code]改成[code="java"]form.dom.submit = function() { [/code]
