I have strange problem with the delay function here using the HTML function with it.
I set an HTML text by using $( \'#element\').html( \'Hello World\');
delay() defaults to the animation queue, for effects like fadeOut(), etc. You should use setTimeout() instead:
window.setTimeout(function () {
$("#element").html(' ');
}, 3000);
From http://api.jquery.com/delay/:
jQuery.delay() is best for delaying between queued jQuery effects and such, and is not a replacement for JavaScript's native setTimeout function, which may be more appropriate for certain use cases.
