html規定元素的tab（用於導航時）鍵控制次序的屬性tabindex

實例

帶有指定tab 鍵順序的連結：

<a href="http://www.w3school.com.cn/" tabindex="2">W3School</a>
<a href="http://www.google.com/" tabindex="1">Google</a>
<a href="http://www.microsoft.com/" tabindex="3">Microsoft</a>

瀏覽器支援

幾乎所有瀏覽器均tabindex 屬性，除了Safari。

定義和用法

tabindex 屬性規定元素的 tab 鍵控制順序（當 tab 鍵用於導航時）。

提示與註解

註解：以下元素支援tabindex 屬性：, , , , , , , < ;object>, 以及。 </p><p style="margin: 0px; padding: 0px; border: 0px; font-size: 18px; color: rgb(63, 63, 63); font-family: 微软雅黑; white-space: normal; background-color: rgb(253, 252, 248);">語法</p><div class="code" style="position:relative;
