[javascript] How can I show data using a modal when clicking a table row (using bootstrap)?

I'm sort of a beginner on the whole web development thing and after researching a lot I still couldn't get this done. Any help is very much appreciated. I'm using latest rails version and bootstrap to make things prettier.

I have a page with a table which contains orders from a restaurant. If you click a row I want it to show the order details in a modal window using bootstrap. I have managed to open the modal via onclick+javascript function but it looks kinda messy and I still have no clue how to load the content div of the modal with the order info. Here's the code I have for this:

HTML:

<h1>Orders</h1>
<table class="table table-striped"
  <thead>
    <tr>
      <th>ID</th>
      <th>Customer</th>
      <th>Status</th>
    </tr>
  </thead>
  <tbody>
    <% @restaurant.orders.each do |order| %>
    <tr onclick="orderModal(<%= order.id  %>);">
      <td><%= order.id %></td>
      <td><%= order.customer_id %></td>
      <td><%= order.status %></td>
    </tr>
    <% end %>
  </tbody>
</table>

<div id="orderModal" class="modal hide fade" role="dialog" 
     aria-labelledby="orderModalLabel" aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
    <h3>Order</h3>
  </div>
  <div id="orderDetails"class="modal-body"></div>
  
  <div id="orderItems" class="modal-body"></div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
  </div>
</div>

js:

function orderModal(order_id){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static"
    });
};

The best practice is to ajax load the order information when click tr tag, and render the information html in $('#orderDetails') like this:

  $.get('the_get_order_info_url', { order_id: the_id_var }, function(data){
    $('#orderDetails').html(data);
  }, 'script')

Alternatively, you can add class for each td that contains the order info, and use jQuery method $('.class').html(html_string) to insert specific order info into your #orderDetails BEFORE you show the modal, like:

  <% @restaurant.orders.each do |order| %>
  <!-- you should add more class and id attr to help control the DOM -->
  <tr id="order_<%= order.id %>" onclick="orderModal(<%= order.id  %>);">
    <td class="order_id"><%= order.id %></td>
    <td class="customer_id"><%= order.customer_id %></td>
    <td class="status"><%= order.status %></td>
  </tr>
  <% end %>

js:

function orderModal(order_id){
  var tr = $('#order_' + order_id);
  // get the current info in html table 
  var customer_id = tr.find('.customer_id');
  var status = tr.find('.status');

  // U should work on lines here:
  var info_to_insert = "order: " + order_id + ", customer: " + customer_id + " and status : " + status + ".";
  $('#orderDetails').html(info_to_insert);

  $('#orderModal').modal({
    keyboard: true,
    backdrop: "static"
  });
};

That's it. But I strongly recommend you to learn sth about ajax on Rails. It's pretty cool and efficient.

The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:

...
$('#mySelector')
  .on('show.bs.modal', function(e) {
  var mid;


  if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) 
    mid = $(e.relatedTarget).data('id');
  else
    mid = $(event.target).closest('tr').data('id');

...
