I am new to javascript and need to check if a password field has at least 2 alpha and 2 numeric

Here is my script to check for at least one of each but how do I change it to check for at least 2

 if(!theForm.Password.value.match(/^([a-z]+[0-9]+[a-z0-9]*)|([0-9]+[a-z]+[a-z0-9]*)$/i)){
     alert("Password has to have at least one number and one letter character.");
     theForm.Password.focus();
     return false;
  }
return true;

thanks

I think you 're better off with two separate matches, something like these regexp's:

    match(/[a-zA-Z].*[a-zA-Z]/)
    match(/[0-9].*[0-9]/)

Anyway, if this doesn't help, ask Community Support to move your question form this Notes TA to the JavaScript Topic Area.

You need to use a bracket notation that includes all the possible characters [0-9A-Za-z]
