Regular Expression for checking if a string contains at least one [a-z] & [0-9]

  • 0

Regular Expression for checking if a string contains at least one [a-z] & [0-9]. Two [A-Z] and the length of entire stringenter code here should be 4 to 10 CHARS.

I’ve been trying this for long…but am not able to.

    /^(?=.*?[a-z])(?=.*?[0-9])(?=.*?[A-Z].*?[A-Z]).{4,10}$/

    However, doing the four tests separately with single regexes or getStringLength() would be much more readable and maintainable.
