we didn't use waitpupop control, instead we reference JS essential library directly. the gif image is loaded directly from css from your image folder. I did some testing in Edge, it appears that the gif image only showing properly if i stop the thread after popUpObj.show() command (eg, put alert ("aaa')) . It works fine in firefox and chrome.
<link rel='nofollow' href="Content/ej/web/default-theme/ej.web.all.min.css" rel="stylesheet" />
<script src="Scripts/ej/ej.web.all.min.js"></script>
<style type="text/css">
.e-waitpopup-pane {
z-index:20 !important;
color:white;
background-color:#444242;
}
</style>
<script type="text/javascript">
$(document).ready(function () {
$("#waitingPopUp").ejWaitingPopup({
showOnInit: false,
showImage: true,
target: "#page",
text: "Loading your address info... Please wait.."
});
var popUpObj = $("#waitingPopUp").data("ejWaitingPopup");
$("#btnCheckout").click(function () {
popUpObj.show();
}
});
</script>
<div id="page">
<input type="button" id="btnCheckout" value="Check Out"/>
<div id="waitingPopUp"></div>
</div>
Thanks for your supporting, I think this is a known issue in Microsoft edge/internet explorer for supporting animation from gif file.
