jquery - Javascript RegEx: validate time -


I have a stopwatch variable that can get value in the following format: HH: MM: SS Most of the time. 'HH' can go up to the last 24 hours - basically a valid number

I'm not that good with this regex thingy, but something that is for the most part Well was able to write but failed to validate if the hour is a single digit. Pass the regex near 1:10:09 , although it is invalid it should be part of the valid hour 01 . 

  // var stopWatchTime = '02: 10: 09 '; // valid // var stopwatchtime = '00: 10: 09 '; // valid // var stopwatchtime = '1234: 10: 9'; // valid // var stopWatchTime = ': 10: 09'; // invalid // var stopWatchTime = 'ax: 10: 09'; // invalid var stopWatchTime = '1:10:09'; // invalid, should be 01:10:09. If (! Stopwatchtime match (/ ^ \ d +: \ d {2}: \ d {2} $ /)) {Warning ('Invalid Time -' + Stopwatchtime); } And {alert ('valid time -' + stopwatchtime); }   
 What should I change in regex to say that it should check any number, but should the fraction of the hour be 2 digits or more?  
  
 
  / ^ \ d {2,}: \ d {2}: \ d { 2} $ /   
 Allow it to contain {2,} two or more characters  
 If you want to see things that match And if you can not match, you can play with it  
 Edit: Also, if you want to match up to only 59 in the hour / minute portion then  
 < Code> ^ \ d {2,}: (?: [0-5] \ D): (?: [0-5] \ d) $
