Question

您好，我有一个关于javascript的问题。我在导航栏上有一个菜单链接下拉菜单，并且在technology.php页面上有标签。

当我单击菜单时需要它，例如IT服务。它将重定向到tehcnology.php页，并打开“ IT服务”标签的标签和内容。

我做了如下的javascript代码。但不能正常工作。

有什么问题或遗漏吗？请帮助我

导航栏上的链接

<li class="nav-item dropdown" id="technologyMenu">
    <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
         Solutions
    </a>
    <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
         <a class="dropdown-item" href="technology.php">Technology</a>
         <a class="dropdown-item" href="technology.php#datcom">Data Communication & Internet</a>
         <a class="dropdown-item" href="technology.php#it-services">IT Services</a>
         <a class="dropdown-item" href="technology.php#managed-services">Managed Services</a>
         <a class="dropdown-item" href="technology.php#smart-city">Smart City</a>
    </div>
</li>

我的Javascript

这适用于所有页面，因此我将此代码放在footer.php文件中。我将几个部分分开，例如页眉，页脚

  var hash = window.location.hash;
  
  if (hash != "") {
    
    $('.tab-button').each(function() {
      $(this).removeClass('active');
    });

    $('.tab-box-content').each(function() {
      $(this).removeClass('active');
    });
    
    var link = "";
    $('.tab-button').each(function() {
      link = $(this).attr('id');
      if (link == hash) {
        $(this).addClass('active');
      }
    });

    $('.tab-box-content').each(function() {
      link = $(this).attr('id');
      if ('.'+link == hash) {
        $(this).addClass('active-block');
      }
    });
  }

Answer 1

问题是$（this）.attr（'id'）仅返回id，而window.location.hash还包含“＃”字符。

我简化了一点：

// I have to force a hash for the example here to work
location.hash = "it-services";

// As well as get the hash I remove "#" character. It will make things easier
var hash = window.location.hash.slice(1);

if (hash > "") {
  $('.tab-button').removeClass('active');
  $('.tab-box-content').removeClass('active-block');
  $(`#${hash}`).addClass('active');
  $(`.${hash}`).addClass('active-block');
}

.active, .active-block {
  background: red;
}

导航栏链接在其他页面上打开选项卡吗？
