html - 双击问题导航

标签 html css responsive-design nav flexslider

我创建了一个响应式导航菜单，但在平板电脑上，它有“双击”问题。当您点击主标题时，它会在您单击子标题之前重新加载页面。我尝试了一些 jquery 插件，但它们使我的导航栏下方的 Flexslider 不显示(我不知道它们是否隐藏了它或发生了什么)。有想法该怎么解决这个吗？谢谢

代码笔:http://codepen.io/caguilera0001/pen/jrBgdG (不幸的是，我的 flex slider 没有在代码笔中显示)

 $(window).load(function() {
   $('.flexslider').flexslider({
     animation: "slide",
     directionNav: false,
     slideshowSpeed: 4000,
   });
 });


 //to hide the control arrows 
 $('#carousel-home').flexslider({
   animation: "slide",
   controlNav: false,
   animationLoop: false,
   slideshow: false,
   itemWidth: 170,
   itemMargin: 5,
   asNavFor: '#slider',
   start: function(slider) {
       //HIDE THE ARROWS BY DEFAULT...
       $('#slider .flex-direction-nav').css({
         visibility: 'hidden'
       });

       //THEN INSERT YOUR CUSTOM JQUERY CLICK ACTIONS TO REVEAL THEM AGAIN
       slider.find('a').on('click', function() {
         $('#slider .flex-direction-nav').css({
           visibility: 'visible'
         });
       });
     } //end start function
 }); //end carousel

 $('#slider').flexslider({
   slidshow: false,
   animation: "slide",
   controlNav: false,
   animationLoop: false,
   slideshow: true,
   sync: "#carousel-home"
 }); //end slider

最佳答案

它看起来像 href父项中的 anchor <li>这引起了问题。使用 href="/" ，如您所见，重新加载页面。我用 href="#"当我有子导航时。这会导致另一个问题(虽然可以修复!):单击/触摸它会将您带到当前页面的顶部。然而，一点点 jQuery 就可以解决这个问题:

$('.has-subnav a').on('click touchstart', function(e){
    e.preventDefault();
});

对于您的子导航，我建议在父类上放置一个类 <li>并更改 href="/"至 href="#" :

<nav id="nav" role="navigation"> <a href="#nav" title="Show navigation">Show navigation</a> <a href="#" title="Hide navigation">Hide navigation</a>

<ul class="clearfix">
    <li><a href="index.html">Home</a></li>

    <li class="has-subnav"><a href="#"><span>About Us</span></a>
        <ul>
        <li><a href="principal's_message.html">Principal's Message</a></li> 
        <li><a href= "mission_and_vision.html">Mission and Vision</a></li> 
        <li><a href= "our_history.html">Our History</a></li> 
        <li><a href= "staff_directory.html">Staff Directory</a></li> 
        <li><a href= "links.html">Links</a></li> 
        <li><a href= "photo_gallery.html">Photo Gallery</a></li> 
</ul>
</li>
... etc
