+<p>{{domxref("HTMLElement")}} 接口的 <strong><code>nonce</code></strong> 属性返回只使用一次的加密数字，被内容安全政策用来决定这次请求是否被允许处理。</p>

+
+<p>以前，并不是所有的浏览器都支持 <code>nonce</code> IDL属性，因此在实际应用场景中，尝试使用<code><a href="https://wiki.developer.mozilla.org/en-US/docs/Web/API/Element/getAttribute">getAttribute</a></code> 作为备选：</p>
+
+<pre class="notranslate">let nonce = script['nonce'] || script.getAttribute('nonce');</pre>
+
+<p>然而，最新的浏览器版本都隐藏了 <code>nonce</code> 值（返回一个空值）。IDL属(<code>script['nonce']</code>)成为唯一的访问方式。</p>
+
+<p>隐藏Nonce是为了阻止攻击者通过某种机制提取出nonce值，比如下面这种方式：</p>

+<pre class="notranslate">script[nonce~=whatever] {
