Refresh panel javascript on refresh

Question

I need to reload my panel contents via javascript. I have two sections in my web page: a) A list of products and b) A panel with product description. When user clicks on a product I display a panel which reads database information using php code using the variable I passed via product click. (panel-id). I pass the panelId to a javascript which displays a modal notifying user a db read is happening and after that it needs to reload the panel contents with new info. What is the method I need to use to refresh this panel so it is forced to read the new value of php variable? show/hide doesn't seem to do the trick.

Javascript:

$('#getInfoModal').on('show.bs.modal', function(e) {

    var panelId = $(e.relatedTarget).data('panel-id');

    //console.log('Progress bar modal calling: ' + panelId);
    // Hide previous modal if any
    $('#main_panel').parent().hide();
    $('#modalProgressBar').progressbar('reset');

    // Emulate delay and close after progress bar finish
    setTimeout(func, 4000);
        function func() {

            $('#getInfoModal').modal('hide');
            $('#main_panel').parent().show(); // Method to force panel reload?
            $('.modal-backdrop').remove();              
    }

    setTimeout(function(){
       $('#modalProgressBar').progressbar(100);
    }, 1000);

});

HTML code:

   <div class="col-lg-14">                  
                  <!-- START panel-->
                  <div id="main_panel" class="panel panel-default panel-demo">
                  <div class="panel-footer">

Answer 1

To refresh your modal below command is enough

$('#getInfoModal').modal("show");

But As far as I understood , you wanted to update the panel body.So what you do is place a div inside your panel body and update it with the content you get from ajax.

For example

 <!-- START panel-->
<div class="panel panel-info">
    <div class="panel-heading"><em class="fa fa-barcode"></em> Serial number: <strong><?php echo $panel_id?></strong> 
    </div>
    <div class="panel-body">
        <div class="media">
            <div class="pull-left">
                <img src="app/img/switch4ports.png" alt="Image" width="150" height="100" data-toggle="tooltip" data-placement="left" title="2 ports connected" class="media-object">
            </div>
        </div>
        <div id="tablecontents"></div>
    </div>
</div>
</div>
<!-- END panel-->

So assuming you getting cotents from server as json , Loop the json and update the table in tablecontents
