Question

我有一个包含各种通知的数组，其中包括各自的标题和说明。我希望通过标题访问某个通知，但我似乎无法在数组中找到匹配项，即使它应该存在。

NotificationMenu = function()
{
   var NotificationItems = new Array();

   this.Application = function(title, description, functionName)
   {
       this.mTitle = title;
       this.mDescription = description;
       this.mFunction = functionName;
       this.mIsActive = true;
   }

   this.registerNotification = function(title, description, functionName)
   {
       NotificationItems.push(new this.Application(title, description, functionName));
   }

   this.activateNotification = function(title)
   {
       console.log("-NotificationMenu: Activating notification " + title);

       // Check through the list of notifications for the one called to be shown
       for(var i = 0; i < NotificationItems.length; ++i)
       {
           if (NotificationItems[i].mName === title)
           {
               // This is never getting called
               console.log("-NotificationMenu: Successful entry");
           }
       }
   }
}

我访问数组的方式有什么问题，以至于无法匹配两个游戏？特别是，行if(NotificationItems[i].mName === title)永远不会返回true。

mName构造函数中没有定义Application()。也许你的意思是使用mTitle：

if (NotificationItems[i].mTitle === title)

JS阵列无法正常访问
