====== Bootstrap Confirmation ======
Bootstrap confirmation [[http://bootstrap-confirmation.js.org/]] is a JavaScript library that pop up a small confirmation box on something clicked. It requires jQuery, and Bootstrap 3 (or Popper.js + Bootstrap 4) installed.

===== My Typical Use =====
In ''Grails GSP''. Assume we have a controller in Grails that has a function ''def doSomething(CommandObject commandObject){...}'' that take a commandObject with field variable xxx. {{ :bootstrap_confirmation_1.png?direct&200 |}}
<code>
<g:form action="doSomething">
   <g:hiddenField name="commandObject.xxx" value="${commandObject.xxx}"/>
   <button id="delete-btn" type="button" class="btn btn-danger">Delete</button>
</g:form>
</code>

In ''JavaScript''. The following js will find out the closest form from the button that has been clicked if the use click the OK button.
<code>
$(document).ready(function () {
   $("#delete-btn").confirmation({
      rootSelector: '[data-toggle=confirmation]',
      container: 'body',
      popout: true,
      title: "Confirm to delete?",
      btnOkClass: "btn btn-danger",
      btnCancelClass: "btn btn-default",
      onConfirm: function () {
         $(this).closest('form').get(0).submit();
      }
   });
});
</code>

===== Interesting Options =====
Here only listed a few, for more options, go see [[http://bootstrap-confirmation.js.org/#options]].
==== Singleton ====
Instead of using id to select a html component, we can use class name to select multiple html components. Singleton option make sure only of confirmation box shows up.
<code>
singleton: true
</code>
==== Popout ====
Popout allows the confirmation box to be dismissed if it is on blur(Clicking elsewhere other than the confirmation box).
<code>
popout: true
</code>
