javascript and regularexpression?

Question

hi, i have a doubt that whether javascript expression is better or regularexpression is better. i mean for validation javascript is best or ?How it is different form each other? thank you.

Answer 1

Surya,

Javascript can help you to build some validation but you should madder what implement the same input validation on the server side.

So it's only to make it more user friendly, so you should start implementing your server input validation when you are done and if you have time add the javascript validation.

Answer 2

It depends on the kind of validation that you need.

Suppose if you need to compare two dates then regex won't be enough.
