代码：

<navigator bindtap=“switchTab” class=’{{switchTabOne==true ? “on”:""}}’ open-type=‘switchTab’ data-order=‘0’  hover-class=‘none’ >未使用</navigator>

<navigator bindtap=“switchTab” class=’{{switchTabTwo==true ? “on”:""}}’ open-type=‘switchTab’   data-order=‘1’ hover-class=‘none’ >已过期</navigator>

两个tab标签切换时就会提示<navigator/> should have url attribute when using navigateTo, redirectTo or switchTab
