New issue 221 by
[hidden email]: JQAutocomplete broken on GemStone
http://code.google.com/p/glassdb/issues/detail?id=221Assignments to temporaries (for inter-callback communication) do not work
in GS-2.4.x
This is done in the JQAutocomplete>>search:labels:callback: method, which
does not work in GS
A workaround for the method is included below:
search: aSearchBlock labels: aLabelsBlock callback: aCallbackBlock
"A one argument block aSearchBlock that will be evaluated with the term
the user currently typed. The block is expected to answer a collection of
objects. aLabelsBlock should answer a string label to be displayed for each
object. aCallbackBlock is evaluated with the selected object and an ajax
script to be performed."
| term mapping |
mapping := IdentityDictionary new.
term := Array new: 1. "In GS, we cannot assign to a temp, so we create a
valueholder"
self source: ((self jQuery getJson
callback: [ :value | term at: 1 put: value ]
value: (JSStream on: 'request.term');
text: [ :stream |
stream json: ((aSearchBlock value: (term at: 1)) asArray collect:
[ :object |
GRSmallDictionary new
at: 'label' put: (aLabelsBlock value: object);
at: 'index' put: (mapping at: object ifAbsentPut: [ mapping size + 1
]);
yourself ]) ];
onComplete: 'response(arguments[0])';
dataType: 'jsonp') asFunction: #('request' 'response')).
self onSelect: ((self jQuery ajax
callback: [ :value | term at: 1 put: value greaseInteger ]
value: (JSStream on: 'ui.item.index');
script: [ :script |
mapping keysAndValuesDo: [ :object :value |
value = (term at: 1)
ifTrue: [ aCallbackBlock value: object value: script ] ] ])
asFunction: #('event' 'ui'))
