extjs 文本框后加一个按钮或 文字

项目中用到需要有时在一个文本框后面加一个按钮,网上找了一个。发现宽度太宽了。自己改了改。可以用了。贴个图吧。

  Ext.onReady(function(){
           new Ext.FormPanel({
                     id:'typeForm',
                     renderTo: Ext.getBody(),
                   frame: true,
                   height: 'auto',
           width:400,
           buttonAlign:"center",
         //  labelAlign: "right",
             		 frame: true,
                     labelWidth: 100,
                      title: '函数',
                         items: [
              {name: "username", xtype:'textfield', fieldLabel: "函数名"},
