[mapguide-users] AJAX

[Alain Lebatard]

Jason,

 

The use of AJAX by the viewer is tailored for its need, which is mostly
changing map state, handling selection and getting toolip/hyperlink
information. It is not designed to be extentded by user code can extend.
I think that for adding new interactive elements to the viewer you would
be better off using your own mechanism, which is fairly easy to
implement because the XMLHTTP object does most of the work for you. You
can see examples of use of XMLHTTP in ajaxmappane.templ, for example in
RequestHyperlinkData() and related code.

Hi,

 

The AJAX viewer obviously has some existing infrastructure for handling
client-server interactions. I am planning on adding some interactive
user elements such as suggesting street addresses as the user is typing,
etc.

 

I'd appreciate feedback on whether I should be implementing my own
parallel handling mechanism for this (either Atlas for .Net or maybe one
of the PHP JSON classes) or whether there is some reference for plugging
into the mechanism that the AJAX viewer is already using.

 

Thanks,

Jason
