如何获得一个月的星期六和星期日(日期)+ JAVASCRIPT

Question

如果给定日期(例如-“2014-01-07”)，我希望访问该特定月份(2014年1月)，并获取该月份的date number of the Sundays和Sunday。

在这种情况下，4,11,18,25 -星期六5,12,19,26 -星期日

我想使用java脚本，因为这是一个前端开发。帮我解决this..Thnkz问题

Answer 1

尝试使用这个小提琴

var d = new Date();
var getTot = daysInMonth(d.getMonth(),d.getFullYear()); //Get total days in a month
var sat = new Array();   //Declaring array for inserting Saturdays
var sun = new Array();   //Declaring array for inserting Sundays

for(var i=1;i<=getTot;i++){    //looping through days in month
    var newDate = new Date(d.getFullYear(),d.getMonth(),i)
    if(newDate.getDay()==0){   //if Sunday
        sun.push(i);
    }
    if(newDate.getDay()==6){   //if Saturday
        sat.push(i);
    }

}
console.log(sat);
console.log(sun);


function daysInMonth(month,year) {
    return new Date(year, month, 0).getDate();
}

在sat和sun Array()中，您可以得到特定月份的星期六和星期日。

Answer 2

使用getDate方法非常容易：

var my_date = "2014-01-07".split('-')
var year = parseInt(my_date[0]);
var month = parseInt(my_date[1])-1;

var saturdays = [];
var sundays = [];

for (var i = 0; i <= new Date(year, month, 0).getDate(); i++) 
{    
    var date = new Date(year, month, i);

    if (date.getDay() == 6)
    {
       saturdays.push(date);
    } 
    else if (date.getDay() == 0)
    {
        sundays.push(date);    
    }
};

console.log(sundays, saturdays);

Answer 3

var d = new Date();
var pred = new Date(d.getFullYear(),d.getMonth()+1,0).getDate();

var nowd;
var sat_array = "";
var sun_array = "";


for (i=1;i<=pred;i++) {

  try {
    console.log(d.getFullYear()+ "-" + (d.getMonth()+1) + "-" + i);
    nowd = new Date(d.getFullYear()+ "-" + (d.getMonth()+1) + "-" + i)

    if (nowd.getUTCDay() == 5)
    {
        sat_array = sat_array + "," + i;
    }

    if (nowd.getUTCDay() == 6)
    {
        sun_array = sun_array + "," + i;
    }


  }
  catch(e) {
      return;
  }

}

console.log("SAT list : " +sat_array);
console.log("SUN list : " +sun_array);
