我有一个Isotope过滤器菜单,我正在使用哈希历史记录,因此如果用户返回页面,过滤器仍会设置。因为我们使用.slideDown来扩展子菜单项,所以当你回到页面时,子菜单项会被隐藏,即使它们中的某些过滤器被选中了。
我正在尝试使用:
if ($('#option1').hasClass('.selected')) {
$('.level-two').slideDown('fast');
}
但是,由于“选择”类是由jQuery过滤器(Isotope)生成的,因此它被忽略。

<li><a href="#filter-mount-wall" data-filter-value=".wall">wall</a></li>
<li><a href="#filter-mount-ground" data-filter-value=".ground">ground</a></li>
</ul>
</div>
</div><!--end options-->
</nav>
CSS:
header nav ul.level-two, header nav ul.level-three {
display:none;
}
JavaScript的:
$(function(){
$('.level-one').hide().fadeIn('fast');
});
$(".trigger-two").one('click', function(){
$(".level-two").slideDown('fast');
});
$(".trigger-three").one('click', function(){
$(".level-three").slideDown('fast');
});
if ($('#option1').is('selected')) {
$('.level-two').slideDown('fast');
}

我猜你错过了'。'
if ($('#option1').is('.selected')) {
$('.level-two').slideDown('fast');
}

不是使用重复的功能复制每次点击的相同过程,而是始终以编程方式触发.selected锚点的点击。
$('.option-combo a.selected').trigger('click');
