js获取当前时间,当日零点,前一周时间

项目场景：

根据时间进行数据的快捷筛选

---

解决方案：

1.获取当前时间和当日零点时间

 //当日
 $("#today").click(function () {
     var currentTime = new Date(Date.now());
     var formattedCurrentTime = currentTime.toLocaleString('zh-CN', { year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' }).replace(/年|月/g, "-").replace(/日/g, " ");
   var  EndDate = formattedCurrentTime.replace(/\//g, "-"); // 将斜线替换为横线

     // 获取当天零点时间并以指定格式展示
     var currentZero = new Date();
     currentZero.setHours(0, 0, 0, 0);
     var formattedZeroTime = currentZero.toLocaleString('zh-CN', { year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' }).replace(/年|月/g, "-").replace(/日/g, " ");
    var  StarDate = formattedZeroTime.replace(/\//g, "-"); // 将斜线替换为横线

     console.log("当前时间：", EndDate);
     console.log("当天零点时间：", StarDate);

     LoadHeatStationCharTime(StarDate, EndDate)
 });

2.获取上周时间

 $("#btnUp").click(function () {
     // 获取当天所在月、日、周
     var week = "";
     var lastMondayMonth = "";
      var lastMondayDate = "";
     var lastMondayYear = "";
   var  getDataTime = "";
   var  currentDate = "";
     // 获取当前星期（0-6，0代表星期天）
     if (new Date().getDay() === 0) {
         week = '星期日'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 6));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate+ " 00:00:00";
     }
     
     if (new Date().getDay() === 1) {
         week = '星期一'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 7));
          lastMondayMonth = lastMonday.getMonth() + 1;
          lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
         console.log("前几天的日期：" + StarDate);
     }
     
     if (new Date().getDay() === 2) {
         week = '星期二'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 1));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
         
     }
    
     if (new Date().getDay() === 3) {
         week = '星期三'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 2));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
     }
     
     if (new Date().getDay() === 4) {
         week = '星期四'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 3));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
     }
    
     if (new Date().getDay() === 5) {
         week = '星期五'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 4));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
     }
     
     if (new Date().getDay() === 6) {
         week = '星期六'
          lastMonday = new Date(new Date().setDate(new Date().getDate() - 5));
          lastMondayMonth = lastMonday.getMonth() + 1;
         lastMondayDate = lastMonday.getDate();
         lastMondayYear = lastMonday.getFullYear();
         StarDate = lastMondayYear + "-" + lastMondayMonth + "-" + lastMondayDate + " 00:00:00";
     }
     var formattedCurrentTime = currentTime.toLocaleString('zh-CN', { year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' }).replace(/年|月/g, "-").replace(/日/g, " ");
     EndDate = formattedCurrentTime.replace(/\//g, "-"); // 将斜线替换为横线
    
    // console.log(EndDate)
     
     LoadHeatStationCharTime(StarDate, EndDate)
 });
