Regular Expression: Allow letters, numbers, and spaces (with at least one letter or number)

Question

I\'m currently using this regex ^[A-Z0-9 _]*$ to accept letters, numbers, spaces and underscores. I need to modify it to require at least one number or letter s

Answer 1

This will validate against special characters and leading and trailing spaces:

var strString = "Your String";

strString.match(/^[A-Za-z0-9][A-Za-z0-9 ]\*[A-Za-z0-9]\*$/)
