導航欄鏈接在其他頁面上打開標簽？

Question

您好，我有一個關於 javascript 的問題。 我在導航欄上有一個菜單鏈接下拉菜單和一個帶有標簽的technology.php頁面。

當我單擊菜單時，我想要它，例如 IT 服務。 它將重定向到tehcnology.php頁面並打開 IT Services 選項卡的選項卡和內容。

我已經制作了如下的 javascript 代碼。 但不能正常工作。

有什么問題或遺漏嗎？ 請幫我

    </a>
    <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">

我的 JavaScript

這適用於所有頁面，所以我將此代碼放在 footer.php 文件中。 我將頁眉、頁腳等幾個部分分開

  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

問題是 $(this).attr('id') 只返回 id 而 window.location.hash 還包括“#”字符。

我簡化了一點：

 // 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; }
