[ka-Map-users] XMLOverlay Multiple Items at Same Point

Sat Oct 21 05:08:35 EDT 2006

hi Wayne,
Thanks for your replies and help you have provided me , Wayne I am not using Xml, and my PHP file doesn't return XML document , it simply return javascript code ,my earlier application had Xml involved, reason I of skipping XML document is I wanted so perform some Mouse Over and No click  actions on POINT, so i used kaxmlPoint.setInnerHtml to add my own html code in POINT , I am wondering if i can do it using XML document,
and other thing is setInterVal needs a javascript function and interval time as argument, and I have to call my PHP file using some javscript function, xmlOverly.loadXml actually needs some XML document that I am generating rather i am generating JavaScript file that manually writes KxmPoints on Map, 

You are right about 
var newScr = document.createElement("SCRIPT");newScr.src = "test.php?scale="+scale+"&lot_id="+lot_id;newScr.type="text/javascript";document.getElementsByTagName("head")[0].appendChild(newScr);

it may keep my html expanding, I checked out in FireFox too, its working fine there but not showing Mouse Over function, is there any alternate of LoadXml, any thing that let application load JavaScript Or PHP file on the fly.

Thanks a lot for your kind response
