将字母附加到变量名上

当我引用它来获取西班牙语或英语XML数据时，我需要将4个字母添加到变量名中。我正在尝试在不写if语句的情况下重用我的函数。将字母附加到变量名上

像这样：

//two options for 
    var spa_my_videos:XMLList; 
    var eng_my_videos:XMLList; 

//APPEND OPTIONS 
    var spanishLang:String = "spa_"; 
    var englishLang:String = "eng_"; 

//CALL FUNCTION AND ADD APPEND OPTION 
    makePlayer (englishLang); 


    function makePlayer (lang:String):void { 

     my_player = new FLVPlayback(); 
     my_player.seekBar = SB; 
     my_player.playPauseButton = PPB; 
     my_player.volumeBar = VB; 

     my_player.x = video_x; 
     my_player.y = video_y; 
     my_player.width = 1023; 
     my_player.height = 630; 

     main_container.addChild (my_player); 

    //THIS IS WERE DEPENDING ON THE VALUE OF LANG I NEED TO USE THE spa_ or eng_ XML data 

     my_player.source = root_path + lang + my_videos[0][email protected]; 
    }

你的问题是一个利特尔混乱，但如果我理解正确的，你，您可以通过使用AS3上提供的Object [“variableName”]功能来解决此问题。此功能允许您通过Object.variable或Object [“variable”]访问变量，因此您可以在字符串上构建变量名称，并使用它来引用您想要的内容。

在makeplayer功能外makeplayer功能

var videos:Object = {}; 
videos[spanishLang] = spa_my_videos[0][email protected]; 
videos[englishLang] = eng_my_videos[0][email protected];

的

my_player.source = root_path + lang + videos[lang][0][email protected];
