Question

默认状态为：

<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 add 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>

所以如果班级没有rfr-opened add 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

这样的东西？

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

Answer 2

尝试并测试：http://jsfiddle.net/eMagu/（我使用检查器检查alt值）

jQuery one liner ...

// set all menu items to closed, then filter just the open class and set to open
$('.menu-item').attr('alt','closed').filter('.rfr-opened').attr('alt','open')

Answer 3

这应该有所帮助：

$('.menu-item').each(function () {
    if ($(this).hasClass('rtf-opened')) $(this).attr('alt', 'open');
    else $(this).attr('alt', 'closed');
});

Answer 4

我认为有些事情是这样的。。。

$('a.menu-item')each(function() {

    if($(this).hasClass('rfr-opened')) {

        $(this).attr('alt', 'open');

    } else {

        $(this).attr('alt', 'closed');
    }
});

Answer 5

这对我有用

jQuery("#rfr-topnav a").click(function () {
$('#rfr-topnav a').attr('title', 'closed');
$('#rfr-topnav a.rfr-opened').attr('title', 'open');
  });

根据类添加alt属性到href
