RegExp.test not working?

Asked 2011-07-22T17:25:37.603

I am trying to validate year using Regex.test in javascript, but no able to figure out why its returning false.

var regEx = new RegExp("^(19|20)[\d]{2,2}$");

regEx.test(inputValue) returns false for input value 1981, 2007

Thanks

Found the REAL issue:

Change your declaration to remove quotes:

var regEx = new RegExp(/^(19|20)[\d]{2,2}$/);

I've noticed, for reasons I can't explain, sometimes you have to have two \\ in front of the d.

so try [\\d] and see if that helps.
