When we use HTML, the page starts to appear once the HTML is downloaded. So, the text appears, the pictures start to appear and the IFRAME does its job such as the Google Map which will start appearing while the rest of the page has been processed. So, the user can get a feeling of the page while it is in progress until it is completed.

When we do DHTML, such as replacing a DIV element with GetElementById(), which will be fired only from a Javascript function by the use of an onload event of an IFRAME, the page will only appear once everything has been downloaded and processed. Because, the onload event of an IFRAME only gets processed on completion. So, basically, whatever is processed that way gives an impression to the user that it takes longer because, even if the HTML is downloaded because nothing appears until the onload event fires.

So, basically, I am looking at enhancing that part so to get the same behavior as a regular HTML page. The concept is having a HTML which contains a DIV. Once a click is done somewhere, this fires a hit into an IFRAME, which is the worker process. This is done in the background, thus invisible to the user. Once the onload event fires from the IFRAME, this will replace that HTML, the one that was returned, into the DIV of the initial page. That is why I am this situation right now. So, I am trying to see if I can enhance that.
