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 =服务器托管网 lastMonday.getFullYear();
StarDate = lastMondayYear + “-” + lastMondayMonth + “-” + lastMondayDate + ” 00:00:00″;

}

if (new Date().getDay() === 3) {
week = ‘星期三’
las服务器托管网tMonday = 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)
});
