It doesn't matter how many letters and digits, but string should contain both.

Jquery function $('#sample1').alphanumeric() will validate given string is alphanumeric or not. I, however, want to validate that it contains both.

So you want to check two conditions. While you could use one complicated regular expression, it's better to use two of them:

if (/d/.test(string) && /[a-zA-Z]/.test(string)) {

This makes your program more readable and may even perform slightly better (not sure about that though).
