1：简单工具栏演示

Ext.onReady(function () {            var tb = new Ext.Toolbar({                renderTo: 'id1',                width:300            });            tb.add([                {text:'新建', handler:tbClick,iconCls:'newIcon'},                { text: '打开', handler: tbClick, iconCls: 'openIcon' },                { text: '保存', handler: tbClick, iconCls: 'saveIcon' }            ]);            function tbClick(btn) {                alert(btn.text);            }        });

2：禁用和启用工具栏

Ext.onReady(function () {            var tb = new Ext.Toolbar({                renderTo: 'id1',                width:300            });            tb.add([                {text:'新建', handler:tbClick,iconCls:'newIcon'},                { text: '打开', handler: tbClick, iconCls: 'openIcon' },                { text: '保存', handler: tbClick, iconCls: 'saveIcon' }            ]);            function tbClick(btn) {                alert(btn.text);            }            Ext.get("enableBtn").on('click', function () { //get里面的参数是一个id为enableBtn的Button                tb.enable();            });            Ext.get("disableBtn").on('click', function () { //get里面的参数是一个id为enableBtn的Button                tb.disable();            });

3：菜单栏初体验,这代码写的容易想砸电脑。脾气不好者慎重

 

Ext.onReady(function () {            //1创建一个Toolbar            var Toolbar = new Ext.Toolbar({                renderTo: 'id1',                width:300            });            //2创建一个Menu对象            var infoMenu = new Ext.menu.Menu({                ignoreParentClicks: true, //忽略父菜单的单击事件                plain: true,                items: [{                    text: '个人信息',                    menu: new Ext.menu.Menu({
    //二级菜单                         ignoreParentClicks: true,                        items: [{                            text: '基本信息',                            menu: new Ext.menu.Menu({ //啊啊啊。好多括号。好咪咪疼                                items: [{                                     text: '身高', handler: onMenuClick },                                        { text: '体重', handler: onMenuClick }]                                                            })                        }]                    })                }]            });            Toolbar.add({ text: '设置', menu: infoMenu })            function onMenuClick(item) {                alert(item.text);            }        });
