jquery - 根据类向 href 添加 alt 属性

Question

默认状态是:

<a  href="./" class="dynamic dynamic-children menu-item"><span class="additional-background"><span class="menu-item-text">Présentation</span></span></a>

所以如果 class = rfr-opened 添加 alt="open"

<a alt="open" href="./" class="dynamic dynamic-children menu-item rfr-opened"><span class="additional-background"><span class="menu-item-text">Présentation</span></span></a>

所以如果类没有 rfr-opened 添加 alt="close"

<a alt="closed" href="./" class="dynamic dynamic-children menu-item"><span class="additional-background"><span class="menu-item-text">Présentation</span></span></a>

Answer 1

类似这样的吗？

$('a').attr('alt', 'closed');
$('a.rfr-opened').attr('alt', 'open');
