--description--

HTML 提供 accesskey 屬性，用於指定激活元素或者使元素獲得焦點的快捷鍵。添加 accesskey 屬性可以讓使用鍵盤的用戶更高效率地導航。

HTML5 允許在任何標籤上使用這個屬性。該屬性尤其適用於鏈接、按鈕、表單組件等元素。

舉個例子：

<button accesskey="b">Important Button</button>

Camper Cat 希望爲他兩篇博客的標題鏈接設置快捷鍵，以使用戶可以快速導航到文章的全文。爲兩個鏈接添加一個 accesskey 屬性，設置第一個的值爲 g（代表 Garfield），設置第二的值爲 c（代表 Chuck Norris）。

--hints--

id 爲 first 的 a 標籤應具有 accesskey 屬性。

assert($('#first').attr('accesskey'));

id 爲 second 的 a 標籤應具有 accesskey 屬性。

assert($('#second').attr('accesskey'));

id 爲 first 的 a 標籤的 accesskey 屬性值應爲 g。注意要使用小寫。

assert($('#first').attr('accesskey') == 'g');

id 爲 second 的 a 標籤的 accesskey 屬性值應爲 c。注意使用小寫。

assert($('#second').attr('accesskey') == 'c');
