未捕获的ReferenceError：isApp未定义

我在控制台中得到“未捕获的ReferenceError：isApp未定义”，我试图从早上早些时候找到此错误的解决方案，但无法获得太多，我isApp.js和mApp.js保存在命名为“JS”的文件夹，有人可以帮我摆脱这个东西....在此先感谢未捕获的ReferenceError：isApp未定义

//"......isApp.js file code starts from here..............." 
 
var iA = function() { 
 
    var t = this; 
 
    this.user; 
 
    var IsInvite = false; 
 
    this.serverUrl = someLocalhostUrl; 
 
    //some function - structure of functions is shown below 
 
    
 
    //this.function1 = function(){ 
 
     //do something 
 
    
 
    //}; 
 
    
 
    //lot of function 
 

 
    this.initialize = function() { 
 
     t.getUser(); 
 
     var pk = typeof t.user; 
 
     if (!(typeof t.user === 'object')) { 
 
      t.user = null; 
 
      t.setUser(); 
 
     } 
 
    }();

你在您的isApp.js文件之前加载您的mApp.js文件，并且两个脚本都正确执行当然，当执行mApp.js时，函数还没有定义。帮了我

<script src="js/mApp.js"></script> 
<script src="js/isApp.js"></script>

感谢兄弟，你的答案救了我的一天，我可能没有甚至花费10多天 –

@ManjeetSingh当事情没有定义，通常是约或者为了执行或不正确的作用域后，注意到这一点。 – Nit

下次我会记住这个提示 –
