将指向当前页面的带有href的链接设置为活动链接（如果在subnav中，则将其父级设置为活动链接）

Posted 2021-02-24

look through the list items in your main nav and based on href of anchor tags this will set the top level link to have an 'active' class.

<script type="text/javascript">
        $(document).ready(function(){
            $(".sf-menu li").children("a").each(function() {
                if(window.location.href == $(this).attr('href')){
                    if($(this).parent().hasClass('main_link')){
                        $(this).addClass('active');                        
                    }else{
                        var topLink = $(this).parents('.main_link');
                        topLink.find('a').first().addClass('active')
                    }
                }
            });
        });
    </script>
