当当前链接用跨度标识时，我一直在尝试从列表中创建一个菜单，并且当我浏览网站时，我会在所有分支上显示父级别和当前级别。我对脚本相当陌生，非常感谢任何帮助示例如果列表是：AA b A bc A b

当前分支跨度在 c 上。我希望列表是：bbcb

-HTML 列表 -

<ul>
    <li><span class="currentbranch0"><a href="/site/">Home</a></span>
    <ul class="multilevel-linkul-0">
        <li><a href="/site/news/">News</a>
        <ul class="multilevel-linkul-1">
            <li><a href="/site/news/internal/">Internal</a>
            <ul class="multilevel-linkul-2">
                <li><a href="/site/news/internal/archive/">Archive</a></li>

脚本

     (document).ready(function() {  var output = '<ul>';
output += $("#side_nav span").last().parent().parent().parent().parent().html();
        output += '</ul>';
        document.getElementById('side_nav').innerHTML = output;
    });$("#side_nav li").ready(function() {
    var count = [];
        $("#side_nav ul[class^='multilevel-']").each(function(){
            var item = $(this).attr('class')
            count.push(item);
            count.sort();
        });


        $('#side_nav li').each(function(){
        if($(this).parent('ul').hasClass(count[count.length-1])){

            $(this).remove();
            };
        });
    });
