javascript - 单击按钮时更改选项卡颜色

Question

我有一个多步骤表单，我想在页面底部添加一个按钮，以便用户可以单击下一步而不是单击顶部的选项卡。

但是该按钮有效，当我单击下一步时，选项卡的背景颜色不会改变。

<div class="right-col">     
    <div class="profile-content"
                <ul id="profile-tabs" class="nav nav-tabs">
                    <li class="active">
                        <a href="#customer-tab" data-toggle="tab">Customer Info</a>
                    </li>
                    <li>
                        <a href="#lead-tab" data-toggle="tab">Lead Info</a>
                    </li>
                </ul>

    <div class="tab-content tab-content-bordered panel-padding">
        <div class="widget-article-comments tab-pane panel no-padding no-border fade in active" id="profile-tabs-board">
           <form class="form-horizontal" action="leads_add_php.php" method="post" name="form1">


                        <div class="form-group">
                            <label for="tag" class="col-sm-3 control-label">Tag</label>
                            <div class="col-sm-9">
                                <input type="text" class="form-control" id="tag" name="tag" placeholder="Tag" onchange="document.getElementById('output_tag').innerHTML = this.value"/>
                            </div>
                        </div>

                        <button type="button" id="next" name="next" class="btn btn-primary">Primary</button>
 <script>

$("#next").click(function(){ 
$("#customer-tab").removeClass("active");
$("#leads-tab").addClass("active");
$("#leads-tab .theme-default .nav-tabs .a").css("background", "red");

});
</script>
        </div> 

BEFORE

AFTER

这是我检查元素时的 CSS

  element.style {
  }
  .theme-default .nav-tabs>li.active>a, .theme-default .nav-tabs>li.active>a:focus, .theme-default .nav-tabs>li.active>a:hover {
  background: #1d89cf;
  border-bottom: 2px solid #1a7ab9;
  }

Answer 1

你必须在 li 标签上设置 id 并给出它的颜色。

$(document).ready(function(){
  $("#next").click(function(){ 
$("#licustomer-tab").removeClass("active");
$("#lileads-tab").addClass("active");
$("#profile-tabs .active a").css("background-color", "red");

});
  });
