My web app contains multiple tree views. Upon loading the page, I first see the unordered lists before the styling of the trees is displayed in the DOM after a brief delay.
Is there a method to mask the web app with a spinner placed in the center of the screen? The spinner would disappear and the mask would fade out once everything on the page has been fully rendered, similar to a semi-transparent mask seen on a lightbox pop-up dialog.
For those dealing with semi-transparent content, the issue may still persist. To resolve this problem, consider adding the following snippet before the closing </body> tag:
<div id="loadingmask"></div>
If necessary, make adjustments to the z-index of the element to ensure compatibility with existing z-index properties.
Here is a sample CSS code to style the loading mask:
#loadingmask
{
width:100%;
height:100%;
position:absolute;
top:0;
background:#000 url(yourspinner.gif) center no-repeat;
}
After completing all other tasks, you can use the following jQuery code:
$('#loadingmask').fadeOut(500, function(){ $(this).remove(); });
