如何使现有水平菜单处于活动状态

Question

有人可以帮我做水平菜单吗？我想在这个菜单上制作一个页面，我需要向css文件添加新类。我希望你能理解我。谢谢

这就是我现在拥有的：菜单主题2.css

    <ul class="theme2">
        <li><a href="index.php"><span>HOME</span></a></li>
        <li><a href="kredity.php"><span>KREDITY</span></a></li>
        <li><a href="shop.php"><span>SHOP</span></a></li>
        <li><a href="aukce.php"><span>AUKCE</span></a></li>
        <li><a href="servery.php"><span>SERVERY</span></a>
        <li><a href="forum"><span>FORUM</span></a></li>
    </ul>

我希望这个在索引.php：

        <ul class="theme2">
        <li><a class="active" href="index.php"><span>HOME</span></a></li>
        <li><a href="kredity.php"><span>KREDITY</span></a></li>
        <li><a href="shop.php"><span>SHOP</span></a></li>
        <li><a href="aukce.php"><span>AUKCE</span></a></li>
        <li><a href="servery.php"><span>SERVERY</span></a>
        <li><a href="forum"><span>FORUM</span></a></li>
    </ul>

Answer 1

尝试这样的事情。

对于水平菜单，您可以在 css 文件中放置以下 css 规则。

.theme2 li {
    float: left;
    list-style: outside none none;
    margin-left: 10px;
}

对于活动类。

 $(function(){
    var url = window.location.pathname;
    alert(url);
    urlRegExp = new RegExp(url.replace(//$/,'') + "$"); 
    // create regexp to match current url pathname and remove trailing slash if present as it could collide with the link in navigation in case trailing slash wasn't present there
    // now grab every link from the navigation
    $('.theme2 ul li a').each(function(){
    // and test its normalized href against the url pathname regexp
        if(urlRegExp.test(this.href.replace(//$/,''))){
            $(this).addClass('active');
        }
    });
  });

Answer 2

index.php
<?php $page = "index"; ?>
shop.php
<?php $page = "shop"; ?>
<ul>
<li><a <?php if($page == 'index') {echo 'class="active"';} ?> href="index.php"><span>HOME</span></a></li>
 <li><a <?php if($page == 'shop') {echo 'class="active"';} ?> href="index.php"><span>SHOP</span></a></li>
</ul>

Answer 3

按照 Nikit 的解决方案，您可以使用 PHP 的 __FILE__ 常量执行以下操作，而无需在每个页面中设置$page变量值：

<ul>
<li><a <?php if(basename(__FILE__, '.php') == 'index') {echo 'class="active"';} ?> href="index.php"><span>HOME</span></a></li>
 <li><a <?php if(basename(__FILE__, '.php')== 'shop') {echo 'class="active"';} ?> href="index.php"><span>SHOP</span></a></li>
</ul>
