[Seaside] script: [...] value parameter

[Johan Brichau]

I copy/paste my response on the Discord channel:

An ajax request with Seaside JQuery can combine multiple secondary callbacks and a single primary callback. You can find out which are which in the method comments on JQAjax. In short: a primary callback is a response-generating callback, while secondary callbacks are callbacks that pass values from the client to the server. 
As such, you can construct what you want already as follows:
| value |
html jQuery ajax 
   callback: [ :v | value := v ] value: (html jQuery this propertyAt: 'id');
   script: [ :s | ...use value in the generation of the script... ]

Also, take a look at passengers if you want to store objects and retrieve them by id. Seaside has this mechanism built-in for you:
| value |
html button
   passenger: self;
   onClick: (html jQuery ajax 
       callback: [ :v | value := v ] passenger: (html jQuery this);
