Javascript or jQuery - Check field contains numbers AND letters

Hi. I need to check the value entered in a password field contains both letters and numbers.
If the user enters just letters, it needs to throw up an error.
If its just numbers, again, an error.
So some examples:

Password: 43242  = ERROR
Password: deef = ERROR
Password: deef2 = CORRECT

I need the code to be as simple as possible, I dont want to use a pre-defined validation script. Something like..

$("#password").blur(function () {
      var b = document.getElementById("#password").value;
      if(b = NUMBERANDLETTER) {
            alert("Password is valid");
                  }
            else {
                  alert("You need to enter numbers and letters");
            }
});

OBVIOUSLY this code is incorrect, but I need it to be as simple as possible.

Need asap!

Thanks!
