这是页面代码，

//计划发车时间 选择时候触发

changeDateTimeColumn1(e) {

var arr = this.data.planStartTime, dateArr = this.data.dateTimeArray1;

arr[e.detail.column] = e.detail.value;

dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]]);

var beginTime = this.data.dateTimeArray1[0][arr[0]] + "-" + this.data.dateTimeArray1[1][arr[1]] + "-" + this.data.dateTimeArray1[2][arr[2]] + " " + this.data.dateTimeArray1[3][arr[3]] + ":" + this.data.dateTimeArray1[4][arr[4]];

var planBeginTime = new Date(Date.parse(beginTime))

var t = new Date();

if (t > planBeginTime) {

wx.showToast({

title: '计划开始时间不能小于当前时间',

icon: 'none',

duration: 2000

})

return;

}

this.setData({

dateTimeArray1: dateArr,

planStartTime: arr

});

},

planStartTime是在这个函数里面修改的，

//计划结束时间 选择时候触发

planEndTimeColumn1(e) {

var arr = this.data.planEndTime, dateArr = this.data.dateTimeArray1;

var arr1 = this.data.planStartTime;//在这里获取，

console.log(arr)

console.log(arr1)

for (var i = 0; i < arr.length ; i++){

if (arr[i] < arr1[i]){

wx.showToast({

title: '计划到达时间不得小于计划发车时间',

icon: 'none',

duration: 2000

})

return;

}

}

}

为什么在后面这个函数里面planStartTime也会被修改，我只是获取数据而已
