Date.prototype.getMonthName = function() {
    var monthNames = [ "January", "February", "March", "April", "May", "June", 
                       "July", "August", "September", "October", "November", "December" ];
    return monthNames[this.getMonth()];
}

它可以被用作

var month_Name = new Date().getMonthName();

Try:

var objDate = new Date("10/11/2009");

var strDate =
    objDate.toLocaleString("en", { day: "numeric" }) + ' ' +
    objDate.toLocaleString("en", { month: "long"  }) + ' ' +
    objDate.toLocaleString("en", { year: "numeric"});

我想到了一个部分解决方案。它使用正则表达式提取月份和日期名称。但当我查看区域和语言选项(窗口)时，我意识到不同的文化有不同的格式顺序……也许更好的正则表达式模式会有用。

function testDateInfo() {
        var months = new Array();
        var days = new Array();
        var workingDate = new Date();
        workingDate.setHours(0, 0, 0, 0);
        workingDate.setDate(1);
        var RE = new RegExp("([a-z]+)","ig");
        //-- get day names 0-6
        for (var i = 0; i < 7; i++) {

            var day = workingDate.getDay();
            //-- will eventually be in order
            if (days[day] == undefined)
                days[day] = workingDate.toLocaleDateString().match(RE)[0];
            workingDate.setDate(workingDate.getDate() + 1);
        }
        //--get month names 0-11
        for (var i = 0; i < 12; i++) {
            workingDate.setMonth(i);
            months.push(workingDate.toLocaleDateString().match(RE)[1]);
        }
        alert(days.join(",") + " \n\r " + months.join(","));
    }

我用了一个很有效的小窍门:

const monthNumber = 8; const yearNumber = 2018; const date = ' ${['Jan'， 'Feb'， 'Mar'， 'Apr'， “五月”，“六月”，“七月”，“八月”， 'Sep'， 'Oct'， 'Nov'， 'Dec'][monthNumber - 1] } $ {yearNumber} '; console.log(日期);

如果我们需要传递输入，那么我们需要使用以下方式

输入:“2020-12-28”

代码:

new Date('2020-12-28').toLocaleString('en-us',{month:'short', year:'numeric'})

输出:“2020年12月”

将名称存储在一个数组中，并根据月份的索引进行查找。

var month=new Array(12);
month[0]="January";
month[1]="February";
month[2]="March";
month[3]="April";
month[4]="May";
month[5]="June";
month[6]="July";
month[7]="August";
month[8]="September";
month[9]="October";
month[10]="November";
month[11]="December";

document.write("The current month is " + month[d.getMonth()]);
