<p><code><font face="Open Sans, Arial, sans-serif">废弃的 </font><strong>arguments.caller</strong></code> 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。</p>

<h2 id="描述">描述</h2>

<p><code>arguments.caller 已经不可使用了，但是你还可以使用</code> {{jsxref("Function.caller")}}。</p>

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

<h3 id="Examples" name="Examples">示例</h3>

<p>下例演示了<code>arguments.caller</code>属性的作用.</p>

<pre class="brush: js example-bad">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!');
}</pre>

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