Comment basculer Plusieurs arguments de la fonction

Question

Veuillez vérifier mon programme J Query. J'ai beaucoup d'entrées de paramètres dans un IF Statements. Y a-t-il un moyen de basculer chaque argument? Mon programme actuel fonctionne bien, mais j'ai besoin de plus de combinaisons. Par exemple, il y a quatre combinaisons donc 4 * 4 = 16 Combinaison pour chaque IF donc y a-t-il une solution pour minimiser l'analyse de tous les arguments?

e.g lower && upper && digit && special 
    lower && special && upper && digit 
    upper && special && digit && upper 
    . 
    . 
    . 
    special && digit && upper && lower

(function($) { 

var LOWER = /[a-z]/, 
    UPPER = /[A-Z]/, 
    DIGIT = /[0-9]/, 
    DIGITS = /[0-9].*[0-9]/, 
    SPECIAL = /[^a-zA-Z0-9]/, 
    SAME = /^(.)\1+$/; 

function rating(rate, message) { 
    return { 
     rate: rate, 
     messageKey: message 
    };

     return rating(0, "too-short"); 

    if (username && password.toLowerCase().match(username.toLowerCase())) 
     return rating(0, "similar-to-username"); 

    if (SAME.test(password)) 
     return rating(1, "very-weak"); 

     var lower = LOWER.test(password),

     return rating(5, "very-strong"); 

    if (lower && upper && digit && special && password.length > 8 || lower && upper && digits && special && password.length > 8 || special && upper && lower && digits && password.length > 8 || lower && special && upper && digits && password.length > 8 || lower && upper && special && digits && password.length > 8 || upper && lower && special && digits && password.length > 8)

// manually add class rule, to make username param optional

comment sur l'utilisation d'un système de notation pour les scores acceptables?

var score = 5; 

    if (!(lower && upper)) { 
    score--; 
    } 
    if (passwordlength <= 8) { 
    score--; 
    } 
    if (!digit) { 
    score--; 
    } 

puis pour les bloqueurs, comme ne pas avoir un mot de passe correspondent au nom d'utilisateur, juste un message d'erreur.
