了解一下Ext.form.TwinTriggerField组件,他有如下几个属性是用来配置旁边按钮的

trigger1Class : String

An additional CSS class used to style the trigger button. The trigger will always get the class 'x-form-trigger' by default and triggerClass will be appended if specified.

trigger2Class : String

你可以到网上找找也可以下载到这样组件的扩展,在2.0的时候是扩展的.现在3.0直接有支持的了,就是Ext.form.TwinTriggerField类
