Re: Tapestry 5 Mixins Remoting JSON
Better have getUrlFromClass generate a url for a {0} parameter (insted of
jsmith)
then (at runtime) have javascript that replaces {0} with whatever value you
want.

the parameter "jsmith" is of course the runtime text the user enters as

username is at the time of checking. Can I use the getUrlFromClass, as
described before, have it generate the url on my template and then have
javascript append jsmith to the url?
So url I get from tapestry component:
var url = ${urlFromClass}
At runtime:
var url = ${urlFromClass} + "/" + username;
Would that work? And what can the method rpcTrigger expect as incoming
parameter for username?

Re: Tapestry 5 Mixins Remoting JSON
Just a small comment on this and a quick way to make it more elegant -
make it generate
href="yourlink/parameter1/parameter2" onclick="rpcFunction(this.href);retrurn
false"
On 5/8/07, Alexandru Dragomir <[EMAIL PROTECTED]> wrote:
The parameters should be in the "urlFromClass" above.
So you could have it like this :
public String getUrlFromClass() {
return resources.createActionLink
("rpcTrigger",false,"jsmith").toString();
}
In my workspace i made a dirty ajax version of actionLink which generates
as href attribute this :
href="javascript:rpcFunction('yourlink/parameter1/parameter2')"
instead of
href="yourlink/parameter1/parameter2"
So , the parameters should be passed in the same way you do it for
ActionLink component(and you have 2 options : use the actionLink
component
or build the link in your class as shown above). The only difference is
that
there is a javascript function that does the request.

The parameters should be in the "urlFromClass" above.
So you could have it like this :
public String getUrlFromClass() {
return resources.createActionLink("rpcTrigger",false,"jsmith").toString();
}

Re: Tapestry 5 Mixins Remoting JSON
The function rpcFunction() is the async part.
I'm using dojo , so the function looks like :
function rpcFunction() {
var kw = {
url:"${urlFromClass}",
load:function(type, data, evt) {
// do what you want with "data" retrieved from server
side
},
method: "GET",
mimetype:"text/json"
};
dojo.io.bind(kw);
}

Re: Tapestry 5 Mixins Remoting JSON
Yes , you could do like this :
template:
rpcFunction() {
var yourUrl=${urlFromClass}
.
}
component class :
@Inject
private ComponentResources resources;
public String getUrlFromClass() {
return resources.createActionLInk("rpcTrigger",false).toString();
}
StreamResponse onRpcTrigger() {
//build your json object and wrapp it in a StreamResponse
return streamResponse;
}
hope i haven't forgot anything.

Re: Tapestry 5 Mixins Remoting JSON
I didn't get what you meant by jsonrpc bridge.
The way i do it and it works fine is implementing an "onAction" method that
returns StreamResponse :
StreamResponse onActionFromYourComp() {}
The method returns a json object wrapped by the StreamResponse.
Mixins are useful when you want to add new ajax behavior to already existent
"non ajax" aware components(if i'm not wrong.. ).
hope it helps,
Alex

webapp I would integrate JSON-RPC. I started out doing this with my t5 app
and quickly realized I had to write something to put the jsonrpc bridge in
the session (like a listener) and then some component that would have
access
to the session and use the bridge. Then I thought of the mixins, which I
admittedly don't yet fully understand. but then again I guess it's not
fully implemented either ;-)
How would something like auto-complete and validation be done with t5
using
mixins or is it still better to use jsonrpc as I described above? I am
looking at the mixin page and don't really find anything useful there.
thx

Tapestry 5 Mixins Remoting JSON
I have a front-end that wants JSON data from the back-end. Using a regular webapp I would integrate JSON-RPC. I started out doing this with my t5 app and quickly realized I had to write something to put the jsonrpc bridge in the session (like a listener) and then some component that would have access to the session and use the bridge. Then I thought of the mixins, which I admittedly don't yet fully understand. but then again I guess it's not fully implemented either ;-) How would something like auto-complete and validation be done with t5 using mixins or is it still better to use jsonrpc as I described above? I am looking at the mixin page and don't really find anything useful there. thx bjorn -- View this message in context: http://www.nabble.com/Tapestry-5-Mixins-Remoting-JSON-tf3676880.html#a10274739 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
