調用者和Calee返回錯誤

Question

我正在學習JavaScript並嘗試檢查Arguments對象的調用者和calle屬性。

這裏是我的代碼

function showFunc() { 
    var funcname = arguments.calee.name; 
    console.log(funcname); 
} 
showFunc(); 

現在顯示在控制檯說

Uncaught TypeError: Cannot read property 'name' of undefined

請告訴我，我要去哪裏錯了一個錯誤。

Answer 1

其callee不calee

Warning: The 5th edition of ECMAScript (ES5) forbids use of arguments.callee() in strict mode. Avoid using arguments.callee() by either giving function expressions a name or use a function declaration where a function must call itself. more details on caller callee

Why was the arguments.callee.caller property deprecated in JavaScript?

function showFunc() { 
    var funcname = arguments.callee.name; 
    console.log(funcname); 
} 
showFunc();
