通配符於JavaScript（也許這是沒有道理的？）

Question

player.obj.speed = 20; 
computer1.obj.speed = 20; 
computer2.obj.speed = 20; 

到

*.obj.speed =20; //once and for all! 

我覺得這裏我的問題是不夠清楚理解。 我會安裝自動化軟件包，如果需要......但我認爲有最簡單的方法，讓我facepalm ... 反正謝謝！

Answer 1

objectArray = [ //Array of the objects (not their speeds as integers don't get passed by reference, but objects do) 
    player.obj, 
    computer1.obj, 
    computer2.obj 
] 

function setAll(X) 
{ 
    //Go over all the objects 
    for(var i = 0; i < objectArray.length; i++) 
    { 
     objectArray[i].speed = X; 
    } 

} 

這很簡單：創建一個對象數組（將更新原始數據，如同整數或浮點數組一樣）。然後，當您想要更改它們時，只需遍歷數組並設置每個人的速度屬性即可。
