`废弃的 arguments.caller` 属性原先用在函数执行的时候调用自身。本属性已被移除且不再有用。

## 描述

`arguments.caller 已经不可使用了，但是你还可以使用` `Function.caller`。

    function whoCalled() {
       if (whoCalled.caller == null)
          console.log('I was called from the global scope.');
       else
          console.log(whoCalled.caller + ' called me!');
    }

### 示例

下例演示了`arguments.caller`属性的作用.

    function whoCalled() {
       if (arguments.caller == null)
          console.log('该函数在全局作用域内被调用.');
       else
          console.log(arguments.caller + '调用了我!');
    }

## 规范

无相关标准。JavaScript 1.1 实现，{{bug(7224)}} 移除 caller，因为潜在的不安全性。
