    Default [SOLVED] Can not call API action in JavaScript

    [SOLVED] Can not call API action in JavaScript


    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:

    PHP Code:
    $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:
    HTML Code:
        <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:

    Code:
    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:
    HTML Code:
    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?

    Thanks, using the defined namespace makes sense and works!

    When i
    HTML Code:
    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:

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

    Thanks and best regards,
    Jean Marie

    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.

    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.
