Hi All,
Quick question about the Ajax Slider component in Wonder. What
is the rationale behind the OnChangeServer binding? The behavior
seems to be that if the binding is set - regardless of its value
- an ajax post occurs to set the value. A quick peek at the
source confirms that's what's going on...and the value of the
binding is being ignored. Was this the intended behavior and I'm
missing something? Or would this binding be better expressed as
a boolean?
The binding is supposed to return a JavaScript snippet to be run
in the browser after the slider changes.
Thanks Chuck. How does OnChangeServer differ from OnChange then?
onChange is static JavaScript, it does not make a trip to the
server. onChangeServer sends the current slider position/value back
to the server and has the application dynamically generate the
JavaScript to return to and execute on the client.
[...snip...]
Does that code make more sense with the above explanation?
Sure does, you're absolutely correct.
I hadn't looked hard enough at the Javascript that was generated with
the slider...when onChangeServer is bound, the value it returns is
injected into the event before the script from the onChange binding
(wrapped as parentFunction). Makes sense now.
Thanks!
