Bootstrap选项卡:表单的下一个和上一个按钮

Question

我试图(最终)在几个Bootstrap 3.x选项卡上分割一个表单,但我遇到上一个和下一个按钮的问题.当手动单击选项卡或使用按钮时,只有第一个下一个按钮起作用,有时选项卡内容在选项卡之间根本不会更改.

<ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Shipping</a></li>
    <li><a href="#tab2" data-toggle="tab">Quantities</a></li>
    <li><a href="#tab3" data-toggle="tab">Summary</a></li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="tab1">
        <a class="btn btn-primary" id="btnNext">Next</a>
    </div>
    <div class="tab-pane" id="tab2">
        <a class="btn btn-primary" id="btnNext">Next</a>
        <a class="btn btn-primary" id="btnPrevious">Previous</a>
    </div>
    <div class="tab-pane" id="tab2">
        <a class="btn btn-primary" id="btnPrevious">Previous</a>
    </div>
</div>
<script>
  $('#btnNext').click(function(){
  $('.nav-tabs > .active').next('li').find('a').trigger('click');
});

  $('#btnPrevious').click(function(){
  $('.nav-tabs > .active').prev('li').find('a').trigger('click');
});
</script>

首先是全部:ID必须是独一无二的

这是您的工作代码:http://www.bootply.com/120472

HTML:

<ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Shipping</a></li>
    <li><a href="#tab2" data-toggle="tab">Quantities</a></li>
    <li><a href="#tab3" data-toggle="tab">Summary</a></li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="tab1">
        <a class="btn btn-primary btnNext" >Next</a>
    </div>
    <div class="tab-pane" id="tab2">
        <a class="btn btn-primary btnNext" >Next</a>
        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
    <div class="tab-pane" id="tab3">
        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
</div>

JS:

 $('.btnNext').click(function(){
  $('.nav-tabs > .active').next('li').find('a').trigger('click');
});

  $('.btnPrevious').click(function(){
  $('.nav-tabs > .active').prev('li').find('a').trigger('click');
});

片段:

 $('.btnNext').click(function(){
  $('.nav-tabs > .active').next('li').find('a').trigger('click');
});

  $('.btnPrevious').click(function(){
  $('.nav-tabs > .active').prev('li').find('a').trigger('click');
});

        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
    <div class="tab-pane" id="tab3">
        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
</div>

Answer 2

任何想要在选项卡上执行下一个先前操作的人，请按照以下步骤操作：

a) 在每个选项卡面板中放置下一个上一个按钮

b) 将按钮点击绑定到正文，以便在点击时调用它

c）点击触发点击下一个/上一个选项卡

d) 如果是最后一个选项卡，则将用户重定向到适当的选项卡（调用第一个或最后一个选项卡的显示事件）

/**** JQuery *******/
jQuery('body').on('click','.next-tab', function(){
      var next = jQuery('.nav-tabs > .active').next('li');
      if(next.length){
        next.find('a').trigger('click');
      }else{
        jQuery('#myTabs a:first').tab('show');
      }
});

jQuery('body').on('click','.previous-tab', function(){
      var prev = jQuery('.nav-tabs > .active').prev('li')
      if(prev.length){
        prev.find('a').trigger('click');
      }else{
        jQuery('#myTabs a:last').tab('show');
      }
});

/******* CSS *********/

Answer 3

对于bootstrap 4

<button class="btn btn-info btn-lg previous">Previous</button>
<button class="btn btn-info btn-lg next">Next</button>


$('.next').click(function () {
    $('.nav-tabs > .nav-item > .active').parent().next('li').find('a').trigger('click');
});

$('.previous').click(function () {
    $('.nav-tabs > .nav-item > .active').parent().prev('li').find('a').trigger('click');
});
