引导选项卡:Next &以前的表单按钮

问题描述

我正在尝试(最终)将表单拆分为多个 Bootstrap 3.x 选项卡，但我在使用上一个和下一个按钮时遇到问题.只有第一个下一个按钮起作用，有时当手动单击选项卡或使用按钮时，选项卡内容在选项卡之间根本不会改变.

I am trying to (eventually) split a form over several Bootstrap 3.x tabs, but I am having trouble with the previous and next buttons. Only the first next button functions and sometimes the tab content doesn't change at all between tabs when the tabs are manually clicked OR using the buttons.

<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>

推荐答案

想要在标签上执行下一个先前操作的任何人，请按照以下步骤操作:

Anyone who want to perform next previous operations on tab, follow following steps:

a) 在每个选项卡面板中放置下一个上一个按钮

a) Put next prev buttons in each tab-panel

b) 将按钮点击绑定到正文，以便在点击时调用它

b) Bind the buttons clicks to body so that it will be called on click

c) 在点击触发点击下一个/上一个标签

c) On click trigger click of next/prev tab

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)

d) If it is last tab redirect user to appropriate tab (Call show events of first or last tab)

/**** 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 *********/
