How to reset the bootstrap modal when it gets closed and open it fresh again?

Just reset any content manually when modal is hidden:

$(".modal").on("hidden.bs.modal", function(){
    $(".modal-body1").html("");
});

There is more events. More about them here

$(document).ready(function() {
  $(".modal").on("hidden.bs.modal", function() {
    $(".modal-body1").html("Where did he go?!?!?!");
  });
});

<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch modal
</button>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span>
        </button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <div class='modal-body1'>
          <h3>Close and open, I will be gone!</h3>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>


Tried it and working well

$('#MyModal').on('hidden.bs.modal', function () {
    $(this).find('form').trigger('reset');
})

reset is dom build-in funtion, you can also use $(this).find('form')[0].reset();

And Bootstrap's modal class exposes a few events for hooking into modal functionality, detail at here.

hide.bs.modal This event is fired immediately when the hide instance method has been called.

hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).


What helped for me, was to put the following line in the ready function:

$(document).ready(function()
{
    ..
    ...

    // codes works on all bootstrap modal windows in application
    $('.modal').on('hidden.bs.modal', function(e)
    { 
        $(this).removeData();
    }) ;

    ...
    ..
});

When a modal window is closed and opened again, the previous entered and selected values, will be reset to the initial values.

I hope this will help you as well!
