如何通过提供日期格式'yyyy-mm-dd'来获取当天的名字？

根据correct format，我的'2015-03-03'日期为new Date(dateString); {{1}}构造函数。

如何获取星期二的日期名称？

Answer 1

我找到了这个问题的解决方案，所以我想与大家分享一下，使用日期格式获取当天的名字＆＃39; yyyy-mm-dd＆＃39;你必须使用javascript文件moment.js并使用此函数获取所有一天的信息：

var dayInformation = String(moment('2015-03-10'));

Answer 2

由于时区偏离设置，您可能在一周中遇到错误的一天。您可以通过将本地时区偏移（以分钟为单位）乘以一分钟内的毫秒数来纠正此问题。

＆＃13;

var getDayOfWeek = (function () {
  var days = ['Sunday','Monday','Tuesday','Wednesday',
              'Thursday','Friday','Saturday'];
  return function (date) {
    return days[date.getDay()];  
  };
}());

function getLocalizedDate(dateStr) {
  var d = new Date(dateStr);
  return new Date(d.getTime() + d.getTimezoneOffset() * 60000);
}

function daysInMarch() {
    var display = document.querySelector('#display'),
        i = 1,
        dateStr, date, formatted;

    for (; i <= 31; i++) {
        dateStr = '2015-03-' + (i < 10 ? '0' + i : i),
        date = getLocalizedDate(dateStr),
        formatted = 'March ' + date.getDate() + ' 2015 was a ';
  
        display.innerHTML += formatted +  getDayOfWeek(date) + '<br />';  
    }
}

daysInMarch();

＆＃13;

<div id="display"></div>

＆＃13;

var dateName = function ( yyyy, mm, dd ) {
    var monthNames = [
        "January",
        "February",
        "March",
        "April",
        "May",
        "June",
        "July",

    var dayNames = [
        "Monday",
        "Thuesday",
        "Wednesday",
        "Thursday",
        "Friday",
        "Saturday",
        "Sunday"
    ];
    var today = new Date( yyyy, mm-1, dd );
    var dd = today.getDate();
    var dayname = dayNames[today.getDay()-1];
    var mm = monthNames[today.getMonth()];
    var yyyy = today.getFullYear();
    var fullDate = dayname + " " + dd + " " + mm + " " + yyyy;

    alert( "the current date is: " + fullDate );
};

dateName( 2015, 06, 02 );

你可以任何你想要的方式改变它，它完美无瑕
