Hi Aiders,
a friendly debugger stopped by and told me that I might need
WebElement>>onClickDo: aBlock andUpdateMany: anElementOrIdCollection
inside components which sometimes have to update noting at all while
they usually update several elements.
So I changed for category events-ajax:
onClickDo: aBlock andUpdateMany: anElementOrIdCollection
| |
self registerId;
otherAt: #onClickBlock put: aBlock;
onClick: (self dependentInformation: anElementOrIdCollection)
all the ugly details are now in private-Ajax:
dependentInformation: anElementOrIdCollection
"necessary information of elements to update is collected here."
| dependentIds url dependentParms onClickStream |
anElementOrIdCollection ifNil: [^''].
url := self ajaxCallUrl.
dependentIds := anElementOrIdCollection collect:
[:each |
each isSymbol
ifTrue: [each]
ifFalse:
[each registerId.
each id]].
dependentParms := anElementOrIdCollection
collect: [:each | self ajaxCallUrlParametersFor: each].
dependentParms := dependentParms collect:
[:parm |
parm , '&blockElementId=' , self id , '&blockName=onClickBlock'].
onClickStream := WriteStream on: String new.
1 to: dependentParms size
do:
[:index |
onClickStream
nextPutAll: 'new Ajax.Updater(''';
nextPutAll: (dependentIds at: index) asString;
nextPutAll: ''', ''';
nextPutAll: url;
nextPutAll: ''', {method: ''post'', postBody: ''';
nextPutAll: (dependentParms at: index);
nextPutAll: ''', evalScripts: true});'].
^onClickStream contents
Cheers,
