A better refreash

[Beffic]

So my chat system uses meta tags like this:

<META HTTP-EQUIV=Refresh CONTENT="4;url=chatmsgs2.php">

Which makes it refresh the iFrame every four seconds. Which also includes a crappy white screen for a second and then it's back to normal. So I want to use Ajax to fix this problem cause the stupid white screen gives headaches. So can anyone fix my problem?

Here is the iFrame if it helps:

<iframe src=chatmsgs2.php frameborder='1' scrolling=no width="80%" height=400 id=ifr name=ifr frameborder=0></iframe>

setup a div (with a unique ID) that is formatted visually the same as your iframe... find yourself the usual AJAX code block that is everywhere on the intraweb

create another JS that runs a 4 second timer calling the ajax, which will run your php on the backend and flush the results out using innerhtml
