代码：/**模仿tabpanel导航栏*/Ext.define('ux.TabBar', { alternateClassName: 'tabBar', extend: 'Ext.Toolbar', xtype: 'tabBar', config: { docked: 'bottom', cls: 'navToolbar', layout: { align: 'stretch' }, defaults: { flex: 1 }, //被选中的按钮 selectButton: null }, initialize: function () { var me = this; me.callParent(); //监听按钮点击事件 me.on({ delegate: '> button', scope: me, tap: 'onButtonTap' }); }, //更新被选中按钮 updateSelectButton: function (newItem, oldItem) { console.log(oldItem); if (oldItem) { oldItem.removeCls('x-tabBar-pressing'); } if (newItem) { newItem.addCls('x-tabBar-pressing'); } }, //当按钮被点击时 onButtonTap: function (button) { this.setSelectButton(button); }, /** * @private *执行添加项，调用add方法后自动执行 */ onItemAdd: function (item, index) { if (!this.getSelectButton() && item.getInitialConfig('selected')) { this.setSelectButton(item); } this.callParent(arguments); }});需要的css：复制代码 代码如下:.navToolbar { padding:0;}.navToolbar .x-button { border:0; margin:0; border-right:1px solid #585B5B; border-radius:0; padding:0;}.navToolbar .x-button .x-button-label { font-weight:normal; color:White; font-size:0.6em;}.navToolbar .x-tabBar-pressing { background-image:none; background-color:#0f517e; background-image:-webkit-gradient(linear,50% 0%,50% 100%,color-stop(0%,#0a3351),color-stop(10%,#0c4267),color-stop(65%,#0f517e),color-stop(100%,#0f5280)); background-image:-webkit-linear-gradient(top,#0a3351,#0c4267 10%,#0f517e 65%,#0f5280); background-image:-moz-linear-gradient(top,#0a3351,#0c4267 10%,#0f517e 65%,#0f5280); background-image:-o-linear-gradient(top,#0a3351,#0c4267 10%,#0f517e 65%,#0f5280); background-image:linear-gradient(top,#0a3351,#0c4267 10%,#0f517e 65%,#0f5280);}使用：复制代码 代码如下:Ext.define('app.view.MyBar', { alternateClassName: 'myBar', extend: 'ux.TabBar', xtype: 'myBar', config: { items: [ { xtype: 'button', text: '问卷调查', //只有第一个设置的属性有效 selected: true }, { xtype: 'button', text: '我的积分' }, { xtype: 'button', text: '开奖大厅' }, { xtype: 'button', text: '幸运号码' }, { xtype: 'button', text: '更多' }] }});
