把click事件放到外层，是treepanel的事件var store = new Ext.data.TreeStore({
    listeners: {
          click: function() {
              alert("adfasdf");
              loadPage(this.text, 'page/fucking.jsp');
          }
      },
    root: {
        children: [
  {
      text: "root",
      expanded: true,
      children: [{
          text: "工资管理",
          //展开
          //expanded: true,
          children: [{
              text: "book",
              //叶子节点
              leaf: true,
              //  handler: function(){
              //  alert("adsfsdf");
              // loadPage(this.text,'page/fucking.jsp');
              // }
          }, {
              text: "fucking",
              leaf: true
}]
          }, {
              text: "员工管理",
              children: [{
                  text: "alegrbra",
                  leaf: true
}]
              }
  ]
          },
  { text: "buy lottery tickets", leaf: true }
  ]
    }
});
//树的panel
var tree = new Ext.tree.Panel({
    width: 150,
    height: window.screen.availHeight,
    store: store,
    border: 0,
    rootVisible: false
