<p>废弃的 <code><strong>escape()</strong></code> 方法生成新的由十六进制转义序列替换的字符串. 使用 <a href="Reference/Global_Objects/encodeURI" title='encodeURI() 函数通过将特定字符的每个实例替换为一个、两个、三或四转义序列来对统一资源标识符 (URI) 进行编码 (该字符的 UTF-8 编码仅为四转义序列)由两个 "代理" 字符组成)。'><code>encodeURI</code></a> 或 <a href="Reference/Global_Objects/encodeURIComponent" title="encodeURIComponent()是对统一资源标识符(URI)的组成部分进行编码的方法。它使用一到四个转义序列来表示字符串中的每个字符的UTF-8编码(只有由两个Unicode代理区字符组成的字符才用四个转义字符编码)。"><code>encodeURIComponent</code></a> 代替.</p>

<p>字符的16进制格式值,当该值小于等于0xFF时,用一个2位转移序列: %xx 表示. 大于的话则使用4位序列:%<strong>u</strong>xxxx 表示.</p>
