公司需要用到秒
但是小程序提供的只到分钟
vantui也只到分钟，真的是有问题啊
从网上找了一个试了试可以用如下：
<picker mode="multiSelector" value="{{dateTime1}}" bindchange="changeDateTime1" bindcolumnchange="changeDateTimeColumn1" range="{{dateTimeArray1}}">
<view class="text">
{{dateTimeArray1[0][dateTime1[0]]}}-{{dateTimeArray1[1][dateTime1[1]]}}-{{dateTimeArray1[2][dateTime1[2]]}} {{dateTimeArray1[3][dateTime1[3]]}}:{{dateTimeArray1[4][dateTime1[4]]}}:{{dateTimeArray1[5][dateTime1[5]]}}
</view>
</picker>
data: {
dateTimeArray1: null,
dateTime1: null,
startYear: null,
endYear: null,
},
onLoad: function(options) {
let that = this;
// 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();
this.setData({
dateTimeArray1: obj1.dateTimeArray,
dateTime1: obj1.dateTime
});
},
// 选择日期时间
changeDateTime1(e) {
this.setData({
dateTime1: e.detail.value
});
},
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
});
},
需要引入的文件： var dateTimePicker = require('../../utils/dateTimePicker.js');
function withData(param) {
return param < 10 ? '0' + param : '' + param;
}
function getLoopArray(start, end) {
var start = start || 0;
var end = end || 1;
var array = [];
for (var i = start; i <= end; i++) {
array.push(withData(i));
}
return array;
}
function getMonthDay(year, month) {
var flag = year % 400 == 0 || (year % 4 == 0 && year % 100 != 0), array = null;
switch (month) {
case '01':
case '03':
case '05':
case '07':
case '08':
case '10':
case '12':
array = getLoopArray(1, 31)
break;
case '04':
case '06':
case '09':
case '11':
array = getLoopArray(1, 30)
break;
case '02':
array = flag ? getLoopArray(1, 29) : getLoopArray(1, 28)
break;
default:
array = '月份格式不正确，请重新输入！'
}
return array;
}
function getNewDateArry() {
// 当前时间的处理
var newDate = new Date();
var year = withData(newDate.getFullYear()),
mont = withData(newDate.getMonth() + 1),
date = withData(newDate.getDate()),
hour = withData(newDate.getHours()),
minu = withData(newDate.getMinutes()),
seco = withData(newDate.getSeconds());
return [year, mont, date, hour, minu, seco];
}
function dateTimePicker(startYear, endYear, date) {
// 返回默认显示的数组和联动数组的声明
var dateTime = [], dateTimeArray = [[], [], [], [], [], []];
var start = startYear || 1978;
var end = endYear || 2100;
// 默认开始显示数据
var defaultDate = date ? [...date.split(' ')[0].split('-'), ...date.split(' ')[1].split(':')] : getNewDateArry();
// 处理联动列表数据
/*年月日 时分秒*/
dateTimeArray[0] = getLoopArray(start, end);
dateTimeArray[1] = getLoopArray(1, 12);
dateTimeArray[2] = getMonthDay(defaultDate[0], defaultDate[1]);
dateTimeArray[3] = getLoopArray(0, 23);
dateTimeArray[4] = getLoopArray(0, 59);
dateTimeArray[5] = getLoopArray(0, 59);
dateTimeArray.forEach((current, index) => {
dateTime.push(current.indexOf(defaultDate[index]));
});
return {
dateTimeArray: dateTimeArray,
dateTime: dateTime
}
}
module.exports = {
dateTimePicker: dateTimePicker,
getMonthDay: getMonthDay
}
