Displaying page loading gif in javascript
<p>I am making a ajax submit using dojo.xhrpost. <br>
It takes quite a while to get the response. <br>
So i want to display a page loading gif till i get the response.<br>
At the same time I kinda want to hide or reduce the visibility of the page so that the user cant click anything on the page till the response has been received. <br>
I want to overlay the page loading gif over the entire web page till the response is received. <br></p>
