Ext JS 树控件事件处理实现

2，在Ext树控件中应用事件处理

tree_03.js

Ext.onReady(function(){
var root = new Ext.tree.TreeNode({ //tree，此处无function，采用json格式
id:1,
text:"linjq"
}); 
var c1 = new Ext.tree.TreeNode({
text:"child 1"
}); 
root.appendChild(c1);
root.appendChild(new Ext.tree.TreeNode({
text:"child 2"}));
var tree = new Ext.tree.TreePanel({
width:100,
renderTo:"content",
root:root
}); 
// c1.on("click",function(node,event){alert(node.text);});
// c1.on("click",function(){document.write('<a href="index.jsp">index.jsp</a>')});
c1.on("click",function(){location.href="index.jsp"});
});

<link type="text/css" rel="stylesheet" href="ext/resources/css/ext-all.css" />
<script type="text/javascript" src="ext/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="ext/ext-all.js"></script>
<script type="text/javascript" src="tree_03.js"></script>
