bootstrap.Tab.getInstance(triggerEl) who should triggerEL

[ZhangChengLin]

Navs Tab getInstance()
List Group getInstance()

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getInstance(triggerEl) // Returns a Bootstrap tab instance

triggerEl should be the target element div, not the trigger element? Because the target element will be more accurate.

The target element refers to the following'div.tab-pane' and should not be obtained from the triggered "#myTab a" element.

<!-- Nav tabs -->
<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item" role="presentation">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
  </li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
  <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
  <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
  <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>

Hi @ZhangChengLin,

It's the same for our other plugins (Tooltip, Popover, Dropdown), the needed element is always the trigger element

Hello, @Johann-S

Other things I don’t know, Modal is not, Modal is obtained from the ".modal" element.
