Question

我在点击第一个按钮时如何禁用标签3时遇到问题。单击Activate 2nd tab时，将启用第二个选项卡，但也会启用第三个选项卡;单击Activate 3rd tab时应启用它。

我该怎么办？

<div class="tab-wrapper" id="tab-wrapper">
  <div class="tab-header">
    <ul class="tabs">
      <li><a href="#tab1">Step 1</a></li>
      <li><a href="#tab2">Step 2</a></li>
      <li><a href="#tab3">Step 3</a></li>
    </ul>
  </div>
  <div class="tab_container">
    <div id="tab1" class="tab_content">
      this is tab 1
      <button id="button2">Activate 2nd tab</button>
    </div>
    <div id="tab2" class="tab_content">
      this is tab 2
      <button id="button3">Activate 3rd tab</button>
    </div>

    <div id="tab3" class="tab_content">
      This is tab3

    </div>
  </div>
</div>

</body>

<script type="text/javascript">

  $(function() {

    var activate = false,
    tabLinks = $('.tabs a'),
    tabContent = $('.tab_container').children();

    tabLinks.eq(0).addClass('active'); // Add active class, could possibly go in markup
    $('#tab2').hide();
    $('#tab3').hide(); // Hide second tab


    tabLinks.bind('click', function(e) {
      e.preventDefault();
      if(activate === true) { // Only do something if button has been clicked
        var target = this.hash,
          el = $(this);

        tabLinks.filter('.active').removeClass('active');
        el.addClass('active');

        tabContent.hide(); // Hide all
        $(target).show(); // Show selected
      }
    });

    $('#button2').bind('click', function() {
      activate = true; // Activate tab functionality
      tabLinks.eq(1).trigger('click'); // Trigger a click on the second tab link
    });

    $('#button3').bind('click', function() {
      activate = true; // Activate tab functionality
      tabLinks.eq(2).trigger('click'); // Trigger a click on the third tab link
    });

  });
</script>
</html>

您可以执行以下操作（使用数组来了解选项卡是否已激活而不是仅一个布尔值）：

$(function() {


  var activate = [true, false, false],
    tabLinks = $('.tabs a'),
    tabContent = $('.tab_container').children();

  tabLinks.eq(0).addClass('active'); // Add active class, could possibly go in markup
  $('#tab2').hide(); // Hide second tab
  $('#tab3').hide(); // Hide second tab

  tabLinks.on('click', function(e) {
    e.preventDefault();
    var idx = $(this).data('index');
    if (activate[idx] === true) { // Only do something if button has been clicked
      var target = this.hash,
        el = $(this);

      tabLinks.filter('.active').removeClass('active');
      el.addClass('active');

      tabContent.hide(); // Hide all
      $(target).show(); // Show selected
    }
  });

  $('button').on('click', function() {
    var index = $(this).data('index');
    activate[index] = true; // Activate tab functionality
    tabLinks.eq(index).trigger('click'); // Trigger a click on the second tab link
  });

});

 * {
   padding: 0;
   margin: 0;
 }
 
 body {
   margin: 30px;
 }
 
 .tab-wrapper {
   width: 500px;
 }
 
 .tabs {
   overflow: hidden;
   list-style: none;
 }
 
 .tabs li {
   float: left;
   margin-right: 10px;
   border: 1px solid #ccc;
   border-bottom: 0;
 }
 
 .tabs a {
   display: block;
   padding: 5px;
   width: 100px;
 }
 
 .tabs a.active {
   background: #efefef;
 }
 
 .tab_container > div {
   padding: 10px;
   border: 1px solid #ccc;
 }
 
 button {
   padding: 5px;
 }
