Hi Craig, This can happen ;) a) Most modern browsers have a built in "feature" that warns you if a js programm goes wild [1]. eg: FF automatically stopps "long running scripts" with a message. May be you disabled this behaviour at your browser? If so, you should enable it again.
b) Some time ago, I did find some nice articles, about optimizing loop handling in the browser [2]. Especially the blog posts "part 1"[3] and "part 4"[4] may be interesting for you. ==== c) I'd try this mechanism first. With TW, the DOM handling (as described in part 4) can be a reason, why your loops are "slow". If something changes the TW layout. Eg: if you programmatically create a new tiddler. The TW core needs to update the right sidebar ..., which is "slow", if it needs to be done very often. In TW there are 3 functions to temporary stop this browser layout redraw. store.suspendNotifications(); // your loop goes here! store.resumeNotifications(); store.notifyAll(); see tiddlywiki.org [5] for more info ==== d) Using the search term >> non blocking loop javascript << with google, It did point me to a little library called "Clumpy" [6] I had a short look, and it is the wrapper function you requested :) You should start with the "for_loop" [7]. The library contains functions to create user feedback. eg: 10% - 20% .... 100% done! Stopping, starting a loop is possible too. So this would be worth a try. ==== c) and d) may also work, with fET. Note: may work. hope this helps -mario [1] http://www.nczonline.net/blog/2009/01/05/what-determines-that-a-script-is-long-running/ [2] http://www.nczonline.net/blog/2010/02/09/announcing-high-performance-javascript/ [3] "part 1" http://www.nczonline.net/blog/2009/01/13/speed-up-your-javascript-part-1/ [4] "part 4" http://www.nczonline.net/blog/2009/02/03/speed-up-your-javascript-part-4/ [5] http://tiddlywiki.org/#TiddlyWiki.prototype.notifyAll%20TiddlyWiki.prototype.suspendNotifications%20TiddlyWiki.prototype.resumeNotifications [6] http://www.tumuski.com/code/clumpy/overview/ [7] http://www.tumuski.com/code/clumpy/reference/#for_loop -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
