Bootstrap Modal Form Submit

Question

I have implemented a working Modal form using HTML, Bootstrap CSS and PHP, which displays information about a document. In the footer of the Modal I have a 'Delete Document' button which should post to the same page (index.php). The form doesn't react to the submit button.

Reading up on the subject a lot of people are using AJAX to submit from a Bootstrap Modal. This seems unnecessary? Do I really need to implement a JSON post in AJAX just to submit this Modal?

The code:

<div class="modal-footer">
    <form action="index.php" method="post">
        <input type="hidden" name="DocumentID" value="<?php echo $row['DocumentID']; ?>" />
        <input type="hidden" name="top-search" value="<?php echo $_POST['top-search']; ?>" />
        <button type="submit" name="deleteDocument" class="btn btn-w-m btn-danger" onclick="return confirm('Are you sure you want to delete this Document?')">Delete</button>
    </form>
    <button type="button" class="btn btn-white" data-dismiss="modal">Close</button>
</div>

I have an example where a Modal submits successfully although to a different page using a similar method but using target="_blank"

Its not onclick - but onClick.

Also, you need to place the scripts inside {}. The following code should work.

/*
 * A simple React component
 */
class Application extends React.Component {
  render() {
    return (<div class="modal-footer">
    <form action="index.php" method="post">
        <input type="hidden" name="DocumentID" value="<?php echo $row['DocumentID']; ?>" />
        <input type="hidden" name="top-search" value="<?php echo $_POST['top-search']; ?>" />
        <button type="submit" name="deleteDocument" class="btn btn-w-m btn-danger" onClick={ function() {
      return confirm("Yes/No?");
    }}>Delete</button>
    </form>
    <button type="button" class="btn btn-white" data-dismiss="modal">Close</button>
</div>);
  }
}

/*
 * Render the above component into the div#app
 */
React.render(<Application />, document.getElementById('app'));
