在实际应用中，我们有时候会遇到“基于JS如何写时间选择器，代码是什么”这样的问题，我们该怎样来处理呢？下文给大家介绍了解决方法，希望这篇“基于JS如何写时间选择器，代码是什么”文章能帮助大家解决问题。

dateTime.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
 }
}

      var date = dateTimePicker(stryear,endyear); //调用dateTimePicker方法获取时间(开始时间，结束时间）

   //定义日期时间
      var year = date.dateTimeArray[0]; //年
      var month = date.dateTimeArray[1];//月
      var day = date.dateTimeArray[2];//日
      var time = date.dateTimeArray[3];//时
      var minute = date.dateTimeArray[4];//分

      for (var i = 0; i < year.length; i++) {
        yearInner += '<option>' + year[i] + '</option>'
      }
      document.getElementById("yearSelect").innerHTML = yearInner;
      //月
