The problem is some event are not handled in the same way, so simply faking
a post via ajax will not effectively trigger the event.
And also Im not even talking about the returned value(s) which are not
formated in the same way.
For the fullextent, this was already discussed :
http://lists.maptools.org/pipermail/cartoweb-users/2007-February/002058.html
http://lists.maptools.org/pipermail/cartoweb-users/2007-April/002402.html
For mapsize, the idea is the same, but a bit more complicated, as there are
more element in the template that must be updated.
The mapsize change is intercepted in the "images" coreplugin. What you
should do is :
- change the mapsize template so the change trigger an ajax action (look at
other template for example),
- add new functions in images.ajax.js to update the corresponding elements
in the page with the new values. Simply look in the templates files
(cartoclient.tpl and maybe others) where the variables returned by the
images coreplugin (you can see these in function renderFormPrepare) are used
and do the same but with javascript.
I dont think you need to modify the ClientImages.php, as it already contain
the corresponding ajax related functions.

Hi
Thank for your answer. The functionnalities i need in ajax are fullExtent
and mapSize.
Well by now i'm trying to implement it on the full extent function. Maybe
you could tell me wether i took a wrong path.
On the doSubmit function, instead of the myform.submit(); i do a
x_submitForm(); wich looks like this:
/function x_submitForm(){
xShow(xGetElementById('loadbarDiv'));
var param = AjaxHandler.buildPostRequest();
var laRequete = new Ajax.Request('/cw/htdocs/x_aeag.php', {method:
'post',parameters: param,onComplete: afficherReponse} );
}
/The file x_aeag.php looks like this:
/<?php
$_ENV['CW3_PROJECT'] = 'aeag';
require_once('client.php');
header('Content-Type: text/xml');
?>/
And then i modified the cartoclient.tpl so it produces an xml stream:
/<?xml version="1.0" encoding="UTF-8"?>/
/<reponse>
<bbox>{$bboxMinX},{$bboxMinY},{$bboxMaxX},{$bboxMaxY}</bbox>
<factor>{$factor}</factor>
<mapunits>{$mapUnits}</mapunits>
<scalebarUnits>{$scalebarUnits}</scalebarUnits>
<currentScale>1:{$currentScale}</currentScale>
<mainmap_path>{$mainmap_path}</mainmap_path>
<mainmap_width>{$mainmap_width}</mainmap_width>
<mainmap_height>{$mainmap_height}</mainmap_height>
<scalebar_path>{$scalebar_path}</scalebar_path>
<keymap_path>{$keymap_path}</keymap_path>
</reponse>/
Now my problem is that cartoweb doesn't produce the full extent map image.
A new image is yet generated but with still the same extent. I can't find
why...

Hi
Some plugins and maybe some core functionnalities are not compatible with
ajax.
Simply changing the doSubmit function to only return xmlhttprequest
(ajax) is probably not a good idea as it will break in the cases said
above.
I would suggest to first identify precisely which functionnalities you
use are still using non-ajax mode and then see how to modify these
functionnalities so they work with ajax (if possible)

Hi,
I'm trying to set Cartoweb as a full Ajax application. So i try to
change the doSubmit function of dhtmlInit.js to make it send the form
through an ajax function.
I'd like to know if someone as already done this work, and if possible
to post the code in the list.
Thanks
