Javascript UTC匹配RegExp

Question

I'm trying to test if passed string is matching the following format (Thu, 08 Dec 2011 18:48:38 GMT), but I really suck in regular expressions. Any suggestions? Thanks.

Answer 1

Here's the regular expression to test what you want:

var t = newDate();
/(Mon|Tue|...|Sun)\,\s\d{2}\s(Jan|Feb|...|Dec)\s\d{4}\s\d{2}:\d{2}:\d{2}\sGMT/.test(t.toUTCString())

of course you have to replace the ... with the remaining day and month names
