Hi Eric....thanks...I am sure we are really close...but I cant get it to
work..... seems the onclick is not firing.... the code I am testing is -
<html><iframe src="AAA/testMysql.php" id="testMYSQL"
style="width:100%;height:200px;"></iframe>
<a href="javascript:void(0)" onclick="
var frame=this.previousSibling;
var txt=frame.contentDocument.body.innerHTML;
localStorage.mysql=txt;
">check this out!</a></html>
<<wikify {{localStorage.mysql}}>>
..for now I am just putting the txt into a localStorage so I can quickly
see if it worked...
the php code is returning the text...but clicking the link does do
anything....
note that the TW where this code is embedded is on the same domain as the
php script....hence the reletaive link!
Why does this code work?
Thanks
Skye
