無法設置的不確定

Question

我有這樣的代碼財產「密碼強度」，並獲得在第一行JavaScript錯誤：

錯誤是「無法設置屬性‘密碼強度’的未定義」

代碼：

window.myProject.passwordStrength = function ($, window, document) { 
var desc = new Array(); 
desc[0] = "Very Weak"; 
desc[1] = "Weak"; 
desc[2] = "Better"; 
desc[3] = "Medium"; 
desc[4] = "Strong"; 
desc[5] = "Very Strong"; 
return { 
    maxScore: 5, 
    allowedScore: 4, 
    getStrengthDescription: function(score){ 
     return desc[score]; 
    }, 
    getStrength: function(password){ 


     var score = 0; 

     //if password bigger than 6 give 1 point 
     if (password.length > 6) score++; 

     //if password has both lower and uppercase characters give 1 point 
     if ((password.match(/[a-z]/)) && (password.match(/[A-Z]/))) score++; 

     //if password has at least one number give 1 point 
     if (password.match(/\d+/)) score++; 

     //if password has at least one special caracther give 1 point 
     if (password.match(/.[!,@,#,$,%,^,&,*,?,_,~,-,(,)]/)) score++; 

     //if password bigger than 12 give an other 1 point 
     if (password.length > 12) score++; 
     return score; 
    } 
}; 
}(jQuery, window, document); 

我在我的頁面調用此爲：

<script> 
    $(function() { 
     $(document).ready(function() { 
      var passwordStrength = window.myProject.passwordStrength(); 
      $('#Password').keyup(function() { 
       var strength = passwordStrength.getStrength($(this).val()); 
} 
</script> 

Answer 1

你必須定義對象你定義一個新的屬性到該對象

window.myProject = {}; 
window.myProject.passwordStrength = function ($, window, document) {
