Javascript从日期中删除日期名称 [英] Javascript Remove Day Name from Date

问题描述

我想问一下是否有人从以下示例中删除日期名称"，该警报返回2020年2月29日星期六，我不仅使用Moment.js jQuery，因为我只需要能够处理日期即可下面写为代码的格式.

i wanted to ask if someone knows how to remove the Day Name from the following example,the alert returns Sat Feb 29 2020, im not using Moment.js only Jquery because i only need to be able to handle the date in the format that is written below as code.

var mydate = new Date('29 Feb 2020');
alert(mydate.toDateString());

感谢您阅读此问题，希望我弄清楚我的问题是什么

Thank you for reading this question and hope i make clear what my problem is

推荐答案

The Date#toDateString method would result always returns in that particular format.

因此，您需要使用其他可用的方法来生成，或者可以使用几种方法来删除，

So either you need to generate using other methods available or you can remove using several ways,

---

1.使用 String#split ， Array#slice 和 Array#join

var mydate = new Date('29 Feb 2020');
// split  based on whitespace, then get except the first element
// and then join again
alert(mydate.toDateString().split(' ').slice(1).join(' '));

---

2.使用 String#replace

var mydate = new Date('29 Feb 2020');
// replace first nonspace combination along with whitespace
alert(mydate.toDateString().replace(/^\S+\s/,''));

---

3.使用 String#indexOf 和 String#substr

var mydate = new Date('29 Feb 2020');
// get index of first whitespace
var str = mydate.toDateString();
// get substring
alert(str.substr(str.indexOf(' ') + 1));
