Javascript-如何从ajax responsetext中提取日期时间

Question

Javascript-如何从此Ajax响应文本中提取日期时间：

This text was brought to you by AJAX 
Your request was received at:
Sunday 11 November 2018, 02:40:00 am

Answer 1

我将使用正则表达式来完成此操作。正则表达式：

/\w{3,6}day.*(?:am|pm)$/i

首先匹配3或4个Word chars，然后匹配'day'，然后匹配任意数量的any char，直到达到'am'或'pm'为止，然后字符串的结尾。它使用不区分大小写的匹配。

使用方法：

var text = 'This text was brought to you by AJAX' 
    + 'Your request was received at:'
    + 'Sunday 11 November 2018, 02:40:00 am'

var dateStr = text.match(/\w{3,4}day.*(?:am|pm)$/i);
var date = new Date(dateStr);

修改：

将量词更改为{3,6}，使其也与Wednesday匹配。
