[SOLVED] Can not call API action in JavaScript

[jean_marie]

Hi,

i'm exploring Ext.Direct and stumble when calling the API actions in JavaScript. I'm using this PHP stack http://extjs.com/forum/showthread.php?t=68186.

On server side i have coma_api.php which runs this code after all the default stuff:

$api = new ExtDirect_API();

$api->setRouterUrl('coma_router.php'); // default
$api->setNamespace('Ext.app');
$api->setDescriptor('Ext.app.REMOTING_API');

$api->add(
    array(
    'COMA_API_ViewHandler'
    )
);
... 

Within my test index.php i have this at the end of the file:

    <script type="text/javascript" src="coma_api.php"></script>
    <script type="text/javascript">
        window.onload = function(){
            Ext.Direct.addProvider(Ext.app.REMOTING_API);

            COMA_API_ViewHandler.getUI(function(provider, response){
                alert('tell todd');
            });
        };
    </script>    

When i open index.php Firebug tells me:

Ext.ns('Ext.app');
Ext.app.REMOTING_API = {"url":"coma_router.php","type":"remoting","actions":{"COMA_API_ViewHandler":[{"name":"getUI","len":0,"serverMethod":"getUI"}]},"namespace":"Ext.app"};

But calling COMA_API_ViewHandler gives me an JS error:

Fehler: COMA_API_ViewHandler is not defined
Quelldatei: https://myserver/index.php
Zeile: 46

What i'm doing wrong? Do i miss anything?

Thanks in advance and best regards,
Jean Marie

Off the top of my head, have you tried Ext.app.COMA_API_ViewHandler.getUI?

[jean_marie]

Thanks, using the defined namespace makes sense and works!

When i

console.log(Ext.app);

Firebug tells me:
firebug_ext.direct.jpg

I ran into this error because i followed the official Ext.Direct description (http://extjs.com/products/extjs/direct.php). See chapter Client Side portions of Ext.Direct:

Ext.Direct.addProvider(Ext.app.REMOTING_API);
AlbumList.getAll(function(provider, response) {
 // process response
});

???

Thanks and best regards,

Jean Marie -

If you specified no namespace your client-side stubs would have been generated in the window namespace. Because you specified "Ext.app", they are available there.

Because you specified "Ext.app", they are available there.

100% ;-). I got it.

I tried it without specifying the namespace on server side within the PHP stack implementation and than it works like the documentation example.

But i would prefer the namespace variant.

Thanks and best regards,
