While waiting for a response from a .load(), is there any way to change the cursor to the busy/wait cursor?
Change the body's CSS to cursor: progress.
To do this, just make a "waiting" class with this CSS, and then add/remove the class from the body.
CSS:
.waiting {
cursor: progress;
}
Then in your JS:
$('body').addClass('waiting');
You can remove it later with .removeClass.
