如何根据URL路径添加CSS类？

Question

如何根据我所使用的路径将div类添加到div中，包括如果我有＃在其中它不应该发生？

<div class="popup">
    <ul>
        <li><a href="#vs">Example 1</a></li>
        <li><a href="#bod">Example 2</a></li>
        <li><a href="#ptf">Example 3</a></li>
    </ul>
</div><!-- popup -->

<!-- how would I add the class addMe with javascript depending on the site path? It has to work with # -->

Answer 1

jQuery(function($){
   switch(window.location.hash){
      case "vs":  $(".popup").addClass("class1"); break;
      case "bod":  $(".popup").addClass("class2"); break;
      case "ptf":  $(".popup").addClass("class3"); break;
   }
});

这些都不适合我。这有效：

<script type="text/javascript">
    jQuery(document).ready(function($){
        // Get current url
        // Select an a element that has the matching href and apply a class of 'active'.     Also prepend a - to the content of the link
        var url = window.location.href;
        $('.menu a[href="'+url+'"]').addClass('active');
    });
</script>

菜单结构：

<div class="menu">
    <a href="#" class="menu-element">001</a>
    <a href="#" class="menu-element">002</a>
</div>

这是使用JavaScript＆amp; amp;创建网站动态活动菜单的简单代码。 JQuery的

<style>
.myactive{
     background-color:#F7A751;
    }
    </style>

<script type="text/javascript">
$(function () {
var url = window.location.pathname; 
var activePage = url.substring(url.lastIndexOf('/') + 1);
    activePage === '' ?  $('#home').addClass("myactive") : $('#home').removeClass("myactive") ; // for active index page
    activePage === 'about-us' ? $('#about').addClass("myactive") : $('#about').removeClass("myactive") ; //active about us 
    activePage === 'who-we-are' ? $('#info').addClass("myactive") : 
    $('#info').removeClass("myactive") ; 
});
</script>  

#HTML Part....
 <li id="home"><a href="#">Home</a></li>
 <li id="about"><a href="#">About</a></li>
