Question

我想显示当前周的开始日期和结束日期。（周开始=周一，周末=周日）我设法显示星期一。

但是我无法得到星期天的约会。如果有人有解决方案，请发帖给我。

Answer 1

<script>
Date.prototype.getWeek = function(start)
{
        //Calcing the starting point
    start = start || 0;
    var today = new Date(this.setHours(0, 0, 0, 0));
    var day = today.getDay() - start;
    var date = today.getDate() - day;

        // Grabbing Start/End Dates
    var StartDate = new Date(today.setDate(date));
    var EndDate = new Date(today.setDate(date + 6));
    return [StartDate, EndDate];
}

// test code
var Dates = new Date().getWeek();
alert(Dates[0].toLocaleDateString() + ' to '+ Dates[1].toLocaleDateString())
</script>

我相信这有效。

Answer 2

以下功能可以解决问题：

// return an array of date objects for start (monday)
// and end (sunday) of week based on supplied 
// date object or current date
function startAndEndOfWeek(date) {

  // If no date object supplied, use current date
  // Copy date so don't modify supplied date
  var now = date? new Date(date) : new Date();

  // set time to some convenient value
  now.setHours(0,0,0,0);

  // Get the previous Monday
  var monday = new Date(now);
  monday.setDate(monday.getDate() - monday.getDay() + 1);

  // Get next Sunday
  var sunday = new Date(now);
  sunday.setDate(sunday.getDate() - sunday.getDay() + 7);

  // Return array of date objects
  return [monday, sunday];
}

// Mon Nov 12 2012 00:00:00
// Sun Nov 18 2012 00:00:00
alert(startAndEndOfWeek(new Date(2012,10,14)).join('\n'));

Answer 3

试试这个：

var current = new Date();     // get current date    
var weekstart = current.getDate() - current.getDay() +1;    
var weekend = weekstart + 6;       // end day is the first day + 6 
var monday = new Date(current.setDate(weekstart));  
var sunday = new Date(current.setDate(weekend));

Answer 4

SetDate将设置该月的某一天。在月初和月末使用setDate将导致错误的一周

var curr = new Date("08-Jul-2014"); // get current date
var first = curr.getDate() - curr.getDay(); // First day is the day of the month - the day of the week
var last = first + 6; // last day is the first day + 6
var firstday = new Date(curr.setDate(first)); // 06-Jul-2014
var lastday = new Date(curr.setDate(last)); // 12-Jul-2014

如果设置日期为2014年7月1日，则将显示第一天为2014年6月29日，最后一天为2014年6月5日，而不是2014年7月5日。所以为了解决这个问题，我用了

var curr = new Date();
day = curr.getDay();
firstday = new Date(curr.getTime() - 60*60*24* day*1000); // will return firstday (i.e. Sunday) of the week
lastday = new Date(curr.getTime() + 60 * 60 *24 * 6 * 1000); // adding (60*60*6*24*1000) means adding six days to the firstday which results in lastday (Saturday) of the week

Answer 5

在其他例子中，当星期天在其他月份下降时，你会遇到问题。这应该可以解决问题：

var today, todayNumber, mondayNumber, sundayNumber, monday, sunday;
    today = new Date();
    todayNumber = today.getDay();
    mondayNumber = 1 - todayNumber;
    sundayNumber = 7 - todayNumber;
    monday = new Date(today.getFullYear(), today.getMonth(), today.getDate()+mondayNumber);
    sunday = new Date(today.getFullYear(), today.getMonth(), today.getDate()+sundayNumber);

Answer 6

根据RobG的回答，我最终得到这个星期一，从星期一午夜开始，星期日23：59：59.999结束。

  var weekMap = [6, 0, 1, 2, 3, 4, 5];

  function startAndEndOfWeek(date) {
    var now = new Date(date);
    now.setHours(0, 0, 0, 0);
    var monday = new Date(now);
    monday.setDate(monday.getDate() - weekMap[monday.getDay()]);
    var sunday = new Date(now);
    sunday.setDate(sunday.getDate() - weekMap[sunday.getDay()] + 6);
    sunday.setHours(23, 59, 59, 999);
    return [monday, sunday];
  }

Answer 7

@ReadWriteCode的略微修改答案，这也适用于不同月份。

Date.prototype.getWeek = function()
{
    var today = new Date();
    var day = today.getDay();
    var date = today.getDate() - day;

        // Grabbing Start/End Dates
    var StartDate = new Date();
    var EndDate = new Date();
    StartDate.setHours(0,0,0,0); EndDate.setHours(0,0,0,0);
    StartDate.setDate(today.getDate()-day);
    EndDate.setDate(today.getDate()-day+6);
    return {
        startDate:StartDate,
        endDate: EndDate
    };
} 
var thisWeekDates=new Date().getWeek();

Answer 8

您可以修改返回值以满足您的需求，现在它只返回星期日的完整对象。

Date.prototype.endWeek=function(){
  return new Date(this.getFullYear(), this.getMonth(),(7-this.getDay())+this.getDate());
}

//call like this
var myDate = new Date(); 
var Sunday = myDate.endWeek();
alert("Sunday falls on "+ Sunday.getDate());

Answer 9

我希望这对你有用：

Date.prototype.getWeekEndDate = function () {
    diff = 6 - this.getDay();
    if (diff < 0) {
        diff += 6;
    }
    this.setDate(this.getDate() + (1 * diff));
    return this;
}
Date.prototype.getWeekStartDate = function () {
    diff = this.getDay() - 6;
    if (diff < 0) {
        diff += 7;
    }
    return this.setDate(this.getDate() + (-1 * diff));
}

这些方法将返回一周的开始日期和结束日期。

Answer 10

以下代码也修复了不同月份的问题。

添加了格式“M.dd.yyyy”功能。

function startAndEndOfWeek（setDate） { var day = null; var date = null; var month = null; var year = null; var mon = null; var tue = null; var wed = null; var thu = null; var fri = null; var sat = null; var sun = null;

var now = setDate ? new Date(setDate) : new Date();
now.setHours(0,0,0,0);

var monday = new Date(now); var tuesday = new Date(now); var wednesday = new Date(now); var thursday = new Date(now);
var friday = new Date(now); var saturday = new Date(now); var sunday = new Date(now); 

if(new Date(now).getDay() == 0)
{
    monday.setDate(monday.getDate() - 6);
    tuesday.setDate(tuesday.getDate() - 5);
    wednesday.setDate(wednesday.getDate() - 4);
    thursday.setDate(thursday.getDate() - 3);
    friday.setDate(friday.getDate() - 2);
    saturday.setDate(saturday.getDate() - 1);
    sunday.setDate(sunday.getDate() - 0);
}
else
{
    monday.setDate(monday.getDate() - monday.getDay() + 1);
    tuesday.setDate(tuesday.getDate() - tuesday.getDay() + 2);
    wednesday.setDate(wednesday.getDate() - wednesday.getDay() + 3);
    thursday.setDate(thursday.getDate() - thursday.getDay() + 4);
    friday.setDate(friday.getDate() - friday.getDay() + 5);
    saturday.setDate(saturday.getDate() - saturday.getDay() + 6);
    sunday.setDate(sunday.getDate() - sunday.getDay() + 7);
}

date = monday.getDate();
month = monday.getMonth();
year = monday.getFullYear();
mon = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = tuesday.getDate();
month = tuesday.getMonth();
year = tuesday.getFullYear();
tue = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = wednesday.getDate();
month = wednesday.getMonth();
year = wednesday.getFullYear();
wed = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = thursday.getDate();
month = thursday.getMonth();
year = thursday.getFullYear();
thu = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = friday.getDate();
month = friday.getMonth();
year = friday.getFullYear();
fri = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = saturday.getDate();
month = saturday.getMonth();
year = saturday.getFullYear();
sat = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

date = sunday.getDate();
month = sunday.getMonth();
year = sunday.getFullYear();
sun = getMonthValue(month) + "." + getDateValue(date) + "." +  year;

return [mon, tue , wed, thu, fri, sat, sun];

}

function getMonthValue（month） { 开关（月） { 案例0：返回“Jan”; 打破; 案例1：返回“2月”; 打破; 案例2：返回“Mar”; 打破; 案例3：返回“4月”; 打破; 案例4：返回“五月”; 打破; 案例5：返回“君”; 打破; 案例6：返回“Jul”; 打破; 案例7：返回“8月”; 打破; 案例8：返回“九月”; 打破; 案例9：返回“十月”; 打破; 案例10：返回“11月”; 打破; 案例11：返回“Dec”; 打破; } } function getDateValue（day） { if（parseInt（day）＆lt; 10） { 返回“0”+天; } 返回日; }

Answer 11

使用https://momentjs.com使其更简单。

要获取周从周日开始到周六，然后使用：moment（）。startOf（“ week”）。toDate（）和 moment（）。endOf（“ week”）。toDate（）
要获取一周从星期一开始到星期日结束，然后使用：moment（）。startOf（“ isoWeek”）。toDate（）和moment（）。endOf（“ isoWeek”）。toDate（）

在v2.18.1时刻进行了尝试，可以正常工作。

希望这会有所帮助，有关更多信息，您可以参考一下相关文档。

Answer 13

纯香草JS。没有第三方库。周日至周日上午 00 点返回。

const now = new Date()
const startOfWeek = new Date(now.getFullYear(), now.getMonth(), now.getDate() - now.getDay())
const endOfWeek = new Date(now.getFullYear(), now.getMonth(), startOfWeek.getDate() + 7)

获取当前周的开始日期和结束日期（星期一从星期一开始，到星期日结束）
