I have a Bootstrap modal which is launched from a link. For about 3 seconds it just sits there blank, while the AJAX query fetches the data from the database. How can I implement some sort of a loading indicator? Does twitter bootstrap provide this functionality by default?
EDIT: JS code for modal
<script type="text/javascript">
$('#myModal').modal('hide');
$('div.divBox a').click(function(){
var vendor = $(this).text();
$('#myModal').off('show');
$('#myModal').on('show', function(){
$.ajax({
type: "GET",
url: "ip.php",
data: "id=" + vendor,
success: function(html){
$("#modal-body").html(html);
$(".modal-header h3").html(vendor);
$('.countstable1').dataTable({
"sDom": "T<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
"sPaginationType": "bootstrap",
"oLanguage": {
"sLengthMenu": "_MENU_ records per page"
},
"aaSorting":[[0, "desc"]],
"iDisplayLength": 10,
"oTableTools": {
"sSwfPath": "swf/copy_csv_xls_pdf.swf",
"aButtons": ["csv", "pdf"]
}
});
}
});
});
});
$('#myModal').on('hide', function () {
$("#modal-body").empty();
});
</script>
I solved the same problem following this example:
This example uses the jQuery JavaScript library.
First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML :
<img src="/images/loading.gif" id="loading-indicator" style="display:none" />
And the following to your CSS file:
#loading-indicator {
position: absolute;
left: 10px;
top: 10px;
}
Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:
$(document).ajaxSend(function(event, request, settings) {
$('#loading-indicator').show();
});
$(document).ajaxComplete(function(event, request, settings) {
$('#loading-indicator').hide();
});
This solution is from the following link. How to display an animated icon during Ajax request processing
