How Ajax implements a QQ-like online chat plugin

Ajax implementation of the No-refresh online chat plugin, the effect is very similar to the QQ chat interface-on the original basis of the transformation, the Internet has not been implemented like this.
A period of time to do a forum, is the Phpwind source-5.0, later from the Internet under an online chat plug-in, feeling is not very perfect, on the transformation. Now, my forum is not (now the site is http://www.shou163.com/, Welcome to set the homepage), but the source is still on the hard disk, think should be able to come out to share, so good things can not be buried, ^-^

The implementation code is as follows:
The template file index.htm Insert the following paragraph (note back up first!)

<!--find a place to plug-in

<div class= "T" >
<!--chat Templates--
<table width=98% border=0 align=center cellspacing=1 cellpadding=1>
<tr bgcolor= #F4FBFF >
<TD width= "98%" class= "H" height=25 align=left>
<H2> Online Instant Chat </H2>
</td>
</tr>
<tr height=230>
<TD class=f_two align=center width=5% rowspan=1>
</td>
<TD Class=f_one width=53% height=230>
<iframe NAME=GGB src=bbfc_chat.php frameborder=0 width= "100%" Scrolling=no height= "></IFRAME>"
</td>
</tr>
</table><br>
<!--chat Templates--
</div>
<!--find a place to plug -in

Unzip the following package to the root directory. Note: At that time, the Phpwind 5.0 is now 6 only to change a little, should also be no problem. (No files will be overwritten)
