我正在尝试在我正在处理的网站的页脚中创建一个下拉式垂直导航。它有点适用于台式机。 But on the iPhone I'm testing the media query, when a sublink is selected, it choose the main link "below"it and opens up that link's submenu.我的 HTML CSS 和 JS 如下:

JS:

{
    if( !( 'ontouchstart' in window ) &&
        !navigator.msMaxTouchPoints &&

    this.each( function()

        $( this ).on( 'click', function( e )
        {

            if( item[ 0 ] != curItem[ 0 ] )
            {
                e.preventDefault();
                curItem = item;
            }
        });

        $( document ).on( 'click touchstart MSPointerDown', function( e )
        {
            var resetItem = true,
                parents   = $( e.target ).parents();

            for( var i = 0; i < parents.length; i++ )
                if( parents[ i ] == curItem[ 0 ] )
                    resetItem = false;

            if( resetItem )
                curItem = false;
        });
    });
    return this;

顶部的主标题按我希望的方式工作。但是我用于响应式导航的代码来自不同的样式，我不确定如何改进它。我已经编码了大约半年，所以我知道可能有更好的方法来做这些事情，如果我的代码充满了不必要的冗余，我提前道歉。谢谢。

编辑:如果有帮助，这里是该站点的链接: http://vos.societyhq.com/我应该补充一点，我将为其他屏幕宽度添加媒体查询，但我想从(旧的)iPhone 分辨率开始，并首先让它正常工作。

最佳答案

你在使用 JQuery 吗？

如果是这样，您只需在点击(或悬停)时调用函数并传递要展开的列表的 ID。

JQuery:

function showHideNav(elID){
    $("#" + elID).toggle();
}

HTML

<li onclick="showHideNav(dropdown1)">about
  <ul id="dropdown1">
    ...
  </ul>
</li>
