[游戏开发]将时间戳转日期和对应星期几

export function onChange({ value, formGroupId }) {
  
  let time = new Date(this.timedat(value));//调用时间戳转换的日期,重点在new Date()
  console.log(this.getWeek(time))//调用根据转换的日期得到星期几
  // this.$('tableField_kw2u6vsw').getComponent(formGroupId, 'numberField_kw2u6vt1').setValue(total);
}
 //时间戳转换时间
export function timedat(res) {   //res 为传入的时间戳   例：1648310400000

  var time = new Date(res);

  var y = time.getFullYear();

  var m = time.getMonth() + 1;

  var d = time.getDate();

  return y + '-' + m + '-' + d;    //返回格式  "2022-03-27" 字符串
};
//根据时间判断星期几
export function getWeek(timedat) {  //timedat参数格式：   getWeek（new Date("2022-03-27" )）

  var week;

  if (timedat.getDay() == 0) week = "星期日";

  if (timedat.getDay() == 1) week = "星期一";

  if (timedat.getDay() == 2) week = "星期二";

  if (timedat.getDay() == 3) week = "星期三";

  if (timedat.getDay() == 4) week = "星期四";

  if (timedat.getDay() == 5) week = "星期五";

  if (timedat.getDay() == 6) week = "星期六";

  return week;
}
