单击li后，e.preventDefault将阻止锚定标记

Question

你好，朋友们，我的项目页眉和页脚部分是不同的&我想使页面链接在页眉上的每个页面链接的点击活动。代码正在工作，但是，由于e.preventDefault()，锚标记不工作，如果它被移除，活动类将被添加到li中。处理这种情况的解决方案是什么？

HTML：

<nav class="navbar navbar-default">
    <div class="navbar-header navbar-left">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
        <!-- <h1><a class="navbar-brand" href="home.php"> <span>L</span>ifer</a></h1> -->
        <span><a href="home.php"><img src="images/sv_logo.webp" class="navbar-brand" alt="digital-marketing-logo" ><!-- The Inside Story 100*180--></a></span>
    </div>
    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse navbar-right" id="bs-example-navbar-collapse-1">
        <nav class="link-effect-2" id="link-effect-2">
            <ul class="nav navbar-nav">
                <li class="active"><a href="home.php" class="effect-3">Home</a></li>
                <li><a href="about.php" class="effect-3">About</a></li>
                <li><a href="services.php" class="effect-3">Services</a></li>
                <!-- <li><a href="blog.php" class="effect-3">Blog</a></li>
                <li class="dropdown">
                    <a href="services.php" class="dropdown-toggle effect-3" data-toggle="dropdown">Services<b class="caret"></b></a>
                    <ul class="dropdown-menu agile_short_dropdown">
                        <li><a href="icons.php">Web Icons</a></li>
                        <li><a href="typography.php">Typography</a></li>
                    </ul>
                </li> -->
                <li>
                    <a href="contactus.php" class="effect-3">Contact Us</a>
                </li>
            </ul>
        </nav>
    </div>
</nav>

jQuery：

<script type="text/javascript">
    $(document).ready(function() {
        $(document).on('click', 'li', function() {
            e.preventDefault();
            $(this).closest("ul").find("li").removeClass("active"); 
            $(this).addClass("active"); 
        });    
    });
</script>

忽略我的评论，你可以像这样在你的CSS中定位锚标签：

​

$(document).ready(function() {
  $(document).on('click', 'li', function(e) {
    e.preventDefault();
    $(this).closest("ul").find("li").removeClass("active");
    $(this).addClass("active");
  });
});

.active a {
  color: red;
  text-decoration: none;
}

      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <span><a href="home.php"><img src="images/sv_logo.webp" class="navbar-brand" alt="digital-marketing-logo" ><!-- The Inside Story 100*180--></a></span>

    <nav class="link-effect-2" id="link-effect-2">
      <ul class="nav navbar-nav">
        <li class="active"><a href="home.php" class="effect-3">Home</a></li>
        <li><a href="about.php" class="effect-3">About</a></li>
        <li><a href="services.php" class="effect-3">Services</a></li>
        <li>
          <a href="contactus.php" class="effect-3">Contact Us</a>
        </li>
      </ul>
    </nav>
  </div>
</nav>
