Your regular expression is wrong. If you want only numbers and letter, use this: ^[a-zA-Z0-9]*

In your case:

function cbprValidateUser(username){
    var username = username || '';
    var reg = /^[a-zA-Z0-9]+$/
    if (reg.test(username)){
        return true; }
    else{
        return false;
    }
}

Btw. this code is pure JavaScript ( no jQuery). Cheers
