AJAX Evaluator and Event Handler

Hi group,
I use the following code to insert something via AJAX, but I have
to trigger a alert("insertion complete") if the insertion is completed.
How can I do this? There are no Event Handler here - right?

html evaluator
triggerFormElement: myElement;
callback: [ :script |
script insertion top id: #xyz; with: [ :r| r text 'TOP'].
script insertion bottom; id: #xyz; with: [ :r| r text 'BOTTOM'].
]
.

salute
Thomas

triggerFormElement: myElement;
callback: [ :script |
script insertion top id: #xyz; with: [ :r| r text 'TOP'].
script insertion bottom; id: #xyz; with: [ :r| r text 'BOTTOM'].
script alert: 'Insertion complete'
]

Regards,
John

Yes, that's the solution.

Most JavaScript code is not asynchron and is evaluated from top top
bottom. The exceptions are the AJAX request/updater/evaluator's that
tigger a HTTP request in the background while the JavaScript
evaluation immediately continues (it normally doesn't wait to
complete). That's why you only need an event in those cases.

Hi thomas,

I saw Jhon answer your question but I wanted to add questioning
about the real need to use insertion at all. I use to update the whole
component even if I had to insert or modify 1 row mostly because is more
simple to do it and almost allways a more complete solution to the problem.

just my 2 cents

Sebastian

Thanks for your answers!
In fact I need not a simple alert but some JS code, so I use now:

script insertion top id: locationsId; with: [ :r | r text: 'TOP' ]
script add: (SUStream on: ' some JavaScript Code ')

RE: AJAX Evaluator and Event Handler

Take a look if #text: is a deprecated message. Modern canvas uses #render:

#text: is not deprecated for rendering text directly off the canvas, only
for what should be #with: on things like buttons and anchors. Object
renderOn: is implemented as

renderOn: aRenderer
aRenderer text: self

So #text: is perfectly valid the way he was using it.
