js获取当前时间,当日零点,前一周时间

项目 场景：

解决方案：

//当日
$(“#t o day“).click(function () {
var currentTi m e = new Date(Date.now());
var formatte dCu r re ntTi m e = currentTi me.toLoc aleStri n g(‘zh-CN’, { year: ‘num er ic‘, month: ‘2-digit‘, day: ‘2-digit‘, h o ur: ‘2-digit‘, min ute: ‘2-digit‘, second: ‘2-digit‘ }).replace(/年|月/g, “-“).replace(/日/g, ” “);
var EndDate = formattedCurre ntTime.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();
currentZer o.setHo u rs(0, 0, 0, 0);
var formattedZeroTime = currentZero.toLocaleStr in g(‘zh-CN’, { year: ‘numeric‘, month: ‘2-digit‘, day: ‘2-digit‘, h o ur: ‘2-digit‘, min ute: ‘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);

Loa dHeatStationCh arTime(StarDate, EndDate)
});

2.获取上周时间

$(“#btnUp“).click(function () {
// 获取当天所在月、日、周
var w ee k = “”;
var lastMon dayMonth = “”;
var lastMon dayDate = “”;
var lastMondayYear = “”;
var getDataTime = “”;
v ar currentDate = “”;
// 获取当前星期（0-6，0代表星期天）
if (new Date().getDay() === 0) {
wee k = ‘星期日’
lastMonday = new Date(new Date().setDate(new Date().getDate() – 6));
lastMondayMon th = lastMon day.getMon th() + 1;
lastMon dayDate = lastMon day.getDate();
lastMon dayYear = lastMon day.getFullYear();
StarDate = lastMondayYear + “-” + lastMondayMon th + “-” + lastMondayDate+ ” 00:00:00″;
}

if (new Date().getDay() === 1) {
wee k = ‘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) {
wee k = ‘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.getFu llYear();
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.getFu llYear();
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-di git‘, day: ‘2-di git‘, hour: ‘2-di git‘, minute: ‘2-digit’, second: ‘2-digit’ }).replace(/年|月/g, “-“).replace(/日/g, ” “);
EndDate = formattedCurrentTime.re place(///g, “-“); // 将斜线替换为横线

// console.log(EndDate)

LoadHeatStationCharTime(StarDate, EndDate)
});
