<script type="text/javascript" src="js/extjs/ext-all.js"></script>
<script type="text/javascript">
Ext.onReady(function(){
//创建一棵树
var tree = new Ext.tree.TreePanel(
{
el: 'tree', //表示渲染的DOM的id.界面中有<div id = "tree"></div>相对应最后这棵树就出现在这个div位置上
//TreeLoader完成数据转换和装配节点的功能
loader: new Ext.tree.TreeLoader({dataUrl: 'tree.txt'})
}
);
//设置根节点
var root = new Ext.tree.AsyncTreeNode({text:'中国'});
tree.setRootNode(root);
tree.render(); //对树进行渲染
//只展开第一层节点
//root.expand();
//展开全部节点
root.expand(true,true);
}
);
</script>
</head>
<body>
<div id="tree" ></div>
</body>
