直接上代码了：

<input bindfocus=“getstart” value="{{start}}" placeholder=“始发地” type=“text” />

getstart: function (e) {

    var that = this

    page = 1

    wx.chooseLocation({

      success: function (res) {

        that.getList(that.data.date, res.name, that.data.over)

      }

    })

  }

选择完地点之后，回到页面，点击任意位置bindfocus又会被触发一次，期望bindfocus不被触发
