最近在學習Ext4,記錄一些有關Ext4實現控制項的方法:

Ext4的treePanel和之前3x的版本有一些差別。使用的版本是ext-4.0.7-gpl

html部分:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>無標題文檔</title><link type="text/css" rel="stylesheet" href="css/index.css" /><link type="text/css" rel="stylesheet" href="resources/css/ext-all.css" /><script type="text/javascript" language="javascript" src="ext-all.js"></script><script type="text/javascript" language="javascript" src="locale/ext-lang-zh_CN.js"></script><script type="text/javascript" language="javascript" src="js/index.js"></script></head><body><div id="subMenu"></div></body></html>

js部分:

Ext.onReady(function(){Ext.define('Task', {extend: 'Ext.data.Model',fields: [{name: 'id',  type: 'string'},{name: 'text',  type: 'string'}],});var store = Ext.create('Ext.data.TreeStore',{model: 'Task',proxy: {            type: 'ajax',            url: 'treegrid.json'//必須要搭建個伺服器才可以訪問json,不然會報錯。拒絕訪問    },reader: {            type: 'json'        },root: {            text: 'root',            id: '0',        }});var menuTree = Ext.create('Ext.tree.Panel',{title: '使用者管理',autoScroll:true,  width: "100%",height: "100%",        store: store,        rootVisible: true,        renderTo: 'subMenu',        listeners : {'itemclick' : function(view,record){if(record.data.leaf){alert(record.data.id);}else{if(record.data.expanded){view.collapse(record);}else{view.expand(record);}}}}});menuTree.store.load();});

json資料來源:

{  id:'1',  text:'treenode 1',  expanded:true,  children:[{    id:'11',    text:'treenode 11',    leaf:true  },{    id:'12',    text:'treenode 12',    expanded:true,    children:[{      id:'121',      text:'treenode 121',      leaf:true    },{      id:'122',      text:'treenode 122',      leaf:true    }]  },{    id:'13',    text:'treenode 13',    leaf:true  }]}

一個簡單的treepanel就出現了,至於一些拓展功能,如複選樹,修改,編輯,拖動等功能,可以參照API來實現。
