Javascript-将字符串转换为日期并比较日期 [英] Javascript - Convert string to date and compare dates

问题描述

我有我要访问的日期选择器中的日期-

I have date from the date picker which I am accessing as -

var transdate = $j("input[name='enterdate']").val();

导致 transdate = 6/22/2015

我需要测试输入的日期是否在定义为
startdate ='2015-02的两个日期之间-01'和 enddate ='2015-07-30'

I need to test if the entered date is between two dates which are defined as startdate = '2015-02-01' and enddate = '2015-07-30'

怎么办我在以下代码中将转换日期转换为yyyy-mm-dd格式-

How do I convert the transdate in yyyy-mm-dd format in the following code -

if ((new Date('transdate')>= startdate ) && (new Date('transdate') <= enddate )) {

alert("correct date entered");
}

推荐答案

类似的问题已经问了很多，很多次，但我似乎找不到重复的副本。鉴于Date构造函数解析字符串的可靠性，最简单的解决方案是自己解析字符串：

Similar questions have been asked many, many times but I can't seem to find a duplicate. Given the unreliability of the Date constructor to parse strings, the simplest solution is to parse the string yourself:

function parseMDY(s) {
  var b = s.split(/\D/);
  return new Date(b[2], b[0]-1, b[1]);
}
