Bootstrap: load modal with ajax using form param

Question

I page a page with several forms with buttons, like this:

<form name="openconfirm">
    <input type="hidden" name="itemid" value="123">
    <button type="submit" class="btn btn-sm btn-success ">Item 123</button>
</form>
<form name="openconfirm">
    <input type="hidden" name="itemid" value="124">
    <button type="submit" class="btn btn-sm btn-success ">Item 125</button>
</form>
<form name="openconfirm">
    <input type="hidden" name="itemid" value="125">
    <button type="submit" class="btn btn-sm btn-success ">Item 125</button>
</form>

Each button should open a bootstrap modal with more info about the selected item (so the modal content should be loaded from a remote page which has been passed the itemid param using POST or GET ?)

I believe it should be something like this:

<script>
  $(function(){
      $('form[name="openconfirm"]').on('submit', function(){
       itemid = itemid input from form; <- Not actual code
       openModal(#myModal, "file.php?itemid=" + itemid); <- Not actual code
      })
  })
</script>

I hope you can understand what I need and provide me with some solution. I would be thankful if you could provide me actual code since I'm new to javascript. I'm open to better alternatives from the one I've provided.

Many thanks

Try with this HTML markup

<button type="button" data-toggle="modal" data-target="#myModal" id="123" class="btn someclass">Item 123</button>
<button type="button" data-toggle="modal" data-target="#myModal" id="124" class="btn someclass">Item 124</button>
<button type="button" data-toggle="modal" data-target="#myModal" id="125" class="btn someclass">Item 125</button>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">LOADED CONTENT</div>
    </div>
</div>

and this jQuery

$(function () {
    $('.someclass').on('click', function () {
        var itemid = $(this).attr('id');
        $(".modal-content").load("/file.php?itemid=" + itemid);
    });
});

Currently, this doesn't load any new content because URL /file.php?itemid=123 it's not existent, but try it on your existing project.
