 <p>只有正则表达式使用了表示全局检索的 "<code>g</code>" 标志时，该属性才会起作用。此时应用下面的规则：</p>
 <ul>
  <li>如果 <code>lastIndex</code> 大于字符串的长度，则 <code>regexp.test</code> 和 <code>regexp.exec</code> 将会匹配失败，然后 <code>lastIndex</code> 被设置为 0。</li>
- <li>如果 <code>lastIndex</code> 等于字符串的长度，且该正则表达式匹配空字符串，则该正则表达式匹配从 <code>lastIndex</code> 开始的字符串。（then the regular expression matches input starting at <code style="font-style: normal;">lastIndex</code>.）</li>
+ <li>如果 <code>lastIndex</code> 等于字符串的长度，且该正则表达式匹配空字符串，则该正则表达式匹配从 <code>lastIndex</code> 开始的字符串。（then the regular expression matches input starting at <code>lastIndex</code>.）</li>

  <li>否则，<code>lastIndex</code> 被设置为紧随最近一次成功匹配的下一个位置。</li>

 <p>返回 <code>["", undefined]</code>，即一个数组，其第 0 个元素为匹配的字符串。此种情况下为空字符串，是因为 <code>lastIndex</code> 为 2（且一直是 2），"<code>hi</code>" 长度为 2。</p>
