我是小程序初学者，在网上找到了一段选择日期时间的代码，精确到分的，我想改为只选择日期与小时即可，如图，去掉红框的分钟。请问以下代码应该如何修改，谢谢！

const app = getApp()

var dateTimePicker = require(’…/…/utils/dateTimePicker.js’);

Page({

data: {

dateTimeArray: null,

dateTime: null,

dateTimeArray1: null,

dateTime1: null,

startYear: 2000,

endYear: 2050

},

onLoad() {

// 获取完整的年月日 时分秒，以及默认显示的数组

var obj = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);

var obj1 = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);

// 精确到分的处理，将数组的秒去掉

var lastArray = obj1.dateTimeArray.pop();

var lastTime = obj1.dateTime.pop();

//var a=obj1.datetimearray.pop()

this.setData({

dateTime: obj.dateTime,

dateTimeArray: obj.dateTimeArray,

dateTimeArray1: obj1.dateTimeArray,

dateTime1: obj1.dateTime

});

},

changeDate(e) {

this.setData({ date: e.detail.value });

},

changeTime(e) {

this.setData({ time: e.detail.value });

},

changeDateTime(e) {

this.setData({ dateTime: e.detail.value });

},

changeDateTime1(e) {

this.setData({ dateTime1: e.detail.value });

},

changeDateTimeColumn(e) {

var arr = this.data.dateTime, dateArr = this.data.dateTimeArray;

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

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

this.setData({

dateTimeArray: dateArr,

dateTime: arr

});

},

changeDateTimeColumn1(e) {

var arr = this.data.dateTime1, dateArr = this.data.dateTimeArray1;

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

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

this.setData({

dateTimeArray1: dateArr,

dateTime1: arr

});

}

})

//dateTimePicker.js

function withData(param) {

return param < 10 ? ‘0’ + param : ‘’ + param;

}
