how to check digits present in javascript string or not

Question

I need a regex which check the string contains only A-Z, a-z and special characters but not digits i.e. (0-9). Any help is appreciated.

Answer 1

You can try with this regex:

^[^\d]*$

And sample:

var str = 'test123';
if ( str.match(/^[^\d]*$/) ) {
  alert('matches');
}

Answer 2

Simple:

/^\D*$/

It means, any number of not-a-digit characters. See it in action…

The alternative is to reverse your test. Just check if there's a digit present, using the trivial:

/\d/

…and if that matches, your string fails.
