javascript - 如何使用 jQuery 在单击特定链接时切换到特定选项卡面板？

Question

我有一个使用 jQuery 的选项卡面板，一切正常，除了选项卡内容内的 data-anchor 链接应该切换到特定选项卡。标签页切换正常，但标签页内容不显示。

如何解决这个问题？

HTML:

<div class="tab-panels">
  <ul class="tabs">
    <li class="active" rel="panel1">panel1</li>
    <li rel="panel2" id="custpanel2">panel2</li>
    <li rel="panel3">panel3</li>
    <li rel="panel4">panel4</li>
  </ul>
  <div class="panel active" id="panel1">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

  <div class="panel" id="panel4">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    <a href="custpanel2" data-anchor="#custpanel2">
      Click here
    </a>
  </div>
</div>

JS:

$('.tab-panels .tabs li').on('click', function(){
  var $panel = $(this).closest('.tab-panels');

  $panel.find('.tabs li.active').removeClass('active');
  $(this).addClass('active');

  var panelToShow = $(this).attr('rel');

  $panel.find('.panel.active').fadeOut(300, showNextPanel);

  function showNextPanel(){
    $(this).removeClass('active');

    $('#'+panelToShow).fadeIn(300, function(){
      $(this).addClass('active');
    })
  }
});

//Link inside tab content
$('[data-anchor="#custpanel2"]').on('click', function(e){
    e.preventDefault();
    var $panel = $(this).closest('.tab-panels');

    $panel.find('.tabs li.active').removeClass('active');
    $('.tabs li:nth-child(3)').addClass('active');

    var panelToShow = $(this).attr('rel');


    $panel.find('.panel.active').fadeOut(300, showNextPanel);

    function showNextPanel(){
      $(this).removeClass('active');

      $('#'+panelToShow).fadeIn(300, function(){
        $(this).addClass('active');
      })
    }
});

Answer 1

var panelToShow = $(this).attr('rel');
panelToShow 的值是从名为“rel”的属性中检索的，并且该链接没有“rel”属性，您可以在不修改逻辑的情况下解决问题 例如

rel="panel1"
