推荐答案

您传递的是表示日期的字符串。没有一些帮助，Date对象无法理解它...

但是JavaScript Data对象有一个帮助方法 - 解析（） [ ^ ] .. 。

使用它你可以将你的字符串转换为JavaScript日期...

You are passing a string that represents a date. Date object can not understand it without some help...
However JavaScript Data object has a helper method - parse()[^]...
Using it you can convert your string to JavaScript date...

var myDate1 = new Date(Date.parse(dateString1));

您可以使用

YOURDATE.replace(/-/gm, '/')

instead of

Date.parse(YOURDATE.replace('-', '/').replace('-', '/')

Javascript is best but weird.

Try following and you will not get Invalid date in any browser.

var NEWDATE = Date.parse(YOURDATE.replace('-', '/').replace('-', '/'));
                if (!isNaN(NEWDATE)) {
                    NEWDATE= new Date(NEWDATE);
                   console.log(NEWDATE.getDate());
                   }
