Fetching GET parameters from a Seaside component.

I am calling a Seaside component from JavaScript with one parameter. Does

anyone know how to fetch the parameters in a component? Based upon

some documentation on the net I have tried the following without success:

time:=self session fieldsAt: #time.

Thanks.

Re: Fetching GET parameters from a Seaside component.

The GET params are in the request. Try this:

self requestContext request at: #time

You should use strings rather than symbols for accessing those.

self requestContext request at: 'time'

They're actually keyed by strings in the request. Strings and sybmols
are not equivalent on all platforms, particularly Gemstone. Access by
string will be portable. That's not a bug you want to be bitten by
because it's not at all obvious.

As an alternative, you may want to override #initialRequest: in your component.

cheers,

Re: Fetching GET parameters from a Seaside component.

<base href="x-msg://89/">I'd use a js function installed in the (wrapper div of the) element that corresponds to the component. And that function will make a request that can run a normal seaside callback.

I use prototype so a function to change the state of the component (i.e: closing it) it would look like:

AnOpennableClosable>>beClosedFunctionOn: html

^ JSFunction new

add: (html prototype request

callback: [self beClosed ];

yourself);

yourself

But you want a value so you can use the request's callback:value: like this:

AnOpennableClosable>>beClosedFunctionOn: html

^ JSFunction new

add: (html prototype request

callback: [:val| someState := val] value: 'navigate.to().whereverTheValue[is]' asJSObject;

callback: [self beClosed ];

yourself);

yourself

BTW, observing some custom event and make it react with that, is something that usually rocks

have fun
