使用 js 日期，给你：w3schools.com/jsref/jsref_obj_date.asp

标签： javascript jquery node.js date

【解决方案1】：

您可以在Date 对象上使用toLocaleString()

date = new Date();

newDate = date.toLocaleString('en-US', {year: 'numeric', month: 'long'});

console.log(newDate);

更多信息在这里：Date.prototype.toLocaleString()

【解决方案2】：

试试这个：D

function myFunction() {
    var month = new Array();
    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";

    var d = new Date();
    var month = month[d.getMonth()];
    var year = d.getFullYear();
    document.getElementById("demo").innerHTML = month+year;
}

<button onclick="myFunction()">Try it</button>

<p id="demo"></p>

【解决方案3】：

var date = new Date('Sat Jan 28 2017 05:30:00 GMT+0530 (IST)');
var months = ["January", "February", "March", "April", "May", "June","July", "August", "September", "October", "November", "December"
];
console.log(months[date.getMonth()],date.getFullYear());

【解决方案4】：

考虑使用 moment.js 来格式化/解析日期。这将允许您将输入/输出格式存储在配置中，而不是硬编码解析器实现。 http://momentjs.com/docs/#/parsing/

【解决方案5】：

var arr = ["January","February","March","April","May","June","July","August","September","October","November","December"];

var str=arr[d.getMonth()]+""+d.getFullYear();

console.log(str);
