I want to check an time value string 08:00 or 09:10 etc.

I tried var patt = new RegExp('^[0-9][0-9][:][0-9][0-9]');

but this matches 08:00000 etc.

How do I get it to only march for the five character?

• You don't need to enclose single characters in []. – gen_Eric Commented Feb 25, 2014 at 17:42

Add a dollar sign at the end like that:

var patt = new RegExp('^[0-9][0-9][:][0-9][0-9]$');

Anyway here's a more pact regex to that does the same:

var patt = /^\d{2}:\d{2}$/;
