Did you read ThomThom's: WebDialogs - The Lost Manual — R1 2009NOV09
specifically the section on "Async vs sync Communication"

@thomthom said:

Callbacks from WebDialog Javascript under OSX is asynchronous - so sending multiple callbacks rapidly will eat some of the messages. You'd have to have a messagepump system to verify each message is received by Ruby before sending a new callback from Javascript.

Do you know if anyone has yet managed to build such a system? I searched around a little on the forums and all I could seem to find was stuff like this: http://forums.sketchucation.com/viewtopic.php?f=180&t=22698

The javascript code in the Dynamic Components folder shows what seems to be one half of such a system, and thus gives a bit of a starting point, but it would be nice to have something a little more substantial to start from...

[quote="Myhand":31wco2xd]I see that %(#8000BF)[escape()] and %(#8000BF)[unescape()] are deprecated (in Javascript,) though, and that you are recommending to use [them]

](http://msdn.microsoft.com/en-us/library/dz4x90hk(v)":31wco2xd]The unescape function should not be used to decode Uniform Resource Identifiers (URI). Use decodeURI and decodeURIComponent functions instead.
%(#8000BF)[decodeURI()]
%(#8000BF)[decodeURIComponent()]

Which do you recommend or should I continue with %(#8000BF)[unescape()]?

The old functions are ASCII, the new ones are Unicode.

Taking a look at the most recent released ECMA-262 (but not the latest proposed revision,) the old functions are no longer listed.

see: ECMA-262, 5.1, Global Object: 15.1.3 URI Handling Function Properties
ECMAScript Language Specification
Standard ECMA-262
5.1 Edition / June 2011

Link to the downloadable PDF of the specification.

But you need to handle the situation where an older browser does not have these functions so, write a wrapper in JS:

var unesc = function(uri) { var test = false; if (typeof(decodeURI) == "function") test = true; return test ? decodeURI(uri) ; unescape(uri); }

I use the jQuery .ready() event that loads when the DOM is ready to make a callback back to Ruby. Then I can 100% sure I can use execute_script. Works on both platforms. No need for sleep or timers.

I've made a few notes about WebDialogs: http://forums.sketchucation.com/viewtopic.php?f=180&t=23445

Wowsers, thanks for all the responses. Question answered!

Yes. I gave him a nudge in this direction.

Awesome -- just stuck that into my code and it seems to be working great. Many thanks to both of you for your help.

For instance: iterating through a collection of entities and deleting some:

Example - deleting faces.

This is slow
entities.each { |e| e.erase! if e.is_a?(Sketchup::Face) }

This is faster:
faces = [] entities.each { |e| faces << e if e.is_a?(Sketchup::Face) } entities.erase_entities(faces)

Same goes for selection/deselecting.
Anything where SU offers to do either per item or as an array of items - try to pass array of items.
