javascript：將密鑰從for循環傳遞到另一個函數失敗

Question

我試圖將密鑰從for循環傳遞到另一個函數，並從那裏獲取對象的數據。出於某種原因，當我通過密鑰時，它告訴我它是未定義的。

//this is the for loop from where I call anotherFunction 
for (var key in object) { // note that this is not an array but an object 
    if (object.hasOwnProperty(key)) {    
     console.log("test :"+ anotherObject[key]["anotherProperty"]); //this works 
     anotherFunction(key);    
    } 
} 

function anotherFunction(arg){ 
    console.log("arg: "+arg); //shows the correct argument 
    console.log("test2: "+anotherObject["myProperty"]["anotherProperty"]); //this works, in other words, if I manually type the correct property it works but I want to be able to use the passed along argument 
    console.log("test3: "+anotherObject[arg]["anotherProperty"]); //this doesn't work 
    var arg2 = '"'+arg+'"'; //I tried adding quote characters  
    console.log("test4: "+anotherObject[arg2]["anotherProperty"]); //this doesn't work 
} 

它顯示的錯誤是： 遺漏的類型錯誤：在等

任何想法，爲什麼它不會工作不能讀取屬性未定義「anotherProperty」，我怎麼能得到它的工作？

嘗試console(anotherObject);

可能你的對象小有一點不正確
