[Javascript] Validate date via Regular Expression

[grzegorz.stasica at delphiauto.com]

Hi,

What is wrong with this regular expression:
var re=/\b((19|20)\d{2})[\-](1[0-2]|0?[1-9])[\-](0?[1-9]|[12][0-9]|3[01])/

I'm trying to check if date is correct.Date format should by YYYY-MM-DD but when
I validate  somethig like this: 2002-12-54 the test expression doesn't see any
error ?
