学习ExtJS Panel常用方法_extjs-tutorial js-php.cn

一、属性

frame：布尔类型true 或 false ，为true时表示边框为圆角且具有背景色，取false则反之。

xtype：在EXTJS的可视化组件部署中的一种机制，即通过指定xtype的值，来告诉容量如何初始化所包含的级件，如xtype:"textfiled",表示使用Ext.form.TextFile来进行初始化当前组件。

二、方法
add(Ext.Component/Object_component)：添加一个组件到面板中，运行时方法。

addButton( String/Object config, Function handler, Object scope ) :添加一个按钮到面板中，设计时方法（对象在未构造之前调用）。

_panel.addButton({text:"确定"}); //form按默认宽度自适应创建

_panel.addButton(new Ext.Button({text:"取消",minWidth:200}));

三、事件

render：当前对象被构造后触发（设计时事件）。

renderto（构造参数）：将当前对象所生成的HTML对象存放在指定的对象中（运时时事件）。

两者不能同进使用，否则render不起作用。

三、构造参数

items：指定包含在面板中组件的配置数组如textField。

buttons：指定包含面板中按钮的配置数组。

四、应用举例

  Ext.onReady(function(){
        var _panel = new Ext.Panel({
                title:"人员信息",
                frame:true,
                width:400,
                height:300
            })
            _panel.addButton({text:"确定"});
            _panel.addButton(new Ext.Button({text:"取消",minWidth:200}));
            _panel.render(Ext.getBody());
    }) ;

Ext.onReady(function(){
       var _panel=new Ext.Panel({
             title:"登陆",
             renderTo:Ext.getBody(),
             frame:true,
             width:560,
             height:130,
             layout:"form",
             lableWidth:45,
             defaults:{xtype:"textfield",width:180},
             items:[{fieldLabel:"帐号"},{fieldLabel:"密码"}],
             buttons:[{text:"确定"},{text:"取消"}]

             })
    })
