hello there. i want to simplify the usage of rpc and ran into a problem with
the handler. example:
usage:
-------------------------------------------------------------------------------------
var rpc = new qxgui.utils.Rpc;
rpc.callAsync( "doLogin", [ username, userpw ] );
var result = rpc.getResult();
class:
-------------------------------------------------------------------------------------
qx.Class.define("qxgui.utils.Rpc",
{
extend: qx.core.Object,
construct: function( url, service )
{
// standard-paramenter
some statements ...
// konfigurieren
rpc = new qx.io.remote.Rpc( url, service );
rpc.setTimeout( this.__timeout );
rpc.setCrossDomain( this.__crossDomain );
this.__rpc = rpc;
},
members:
{
// eigenschaften
////////////////////////////////////////////////////////////////////////
__url: "xxx",
__service: "xxx",
__timeout: 5000,
__crossDomain: true,
__rpc: null,
__id: null,
__exc: null,
__result: null,
__rpcRunning: null,
// methoden
////////////////////////////////////////////////////////////////////////
callAsync: function( method, args )
{
var handler = function( result, exc, id )
{
if ( exc == null )
{
this.__result = result;
}
else {
alert( "RPC-Exception: " + exc );
}
};
this.__rpcRunning = this.__rpc.callAsync( handler, method, args
);
},
isRpcRunning: function()
{
return this.__rpcRunning;
},
getResult: function()
{
return this.__result;
}
}
});
how do i get the result into the right scope?
