Question

我对此有点新意，所以请原谅我问，但是我正在使用一个稍微修改过的bootstrap导航栏，并且最近已经正确分配了活动类，但由于某种原因它停止使用最后一个我做的改变......（试图恢复它看看是什么搞砸了，无济于事......）一些温柔的灵魂能否启发我如何使其发挥作用呢？

干杯！ T.F。

这是删除了hrefs并更改li内容的代码我的编辑没有改变你的代码如何工作，它似乎工作正常

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">ACAC</a>
    </div>


    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        
        <li class="active"><a>One</a></li>
        <li><a>Two</a></li>
        <li><a>Three</a></li>
        <li><a>Four</a></li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <a href="#" class="lnklang">EN</a>

      </ul>
    </div>
  </div>
</nav>
.....
<script>
  $(".nav a").on("click", function() {

Answer 2

单击菜单页面导航到新页面。活动菜单已更改，但当页面重新加载到新页面时，它将重置为默认值。

您可以检查document.ready上的页面并设置该页面的活动菜单 -

if (window.location.href.indexOf("noticias") > -1) {
     $(".nav").find(".active").removeClass("active");
     $('.nav a[href$="http://www.base_url.com/notice"]').parent().addClass("active");
}

将http://www.base_url.com/更改为您的实际基本网址。

将活动类添加到导航栏
