Hi everyone,
I need to trigger a Rails action after the autocompletion is completed
(when the user has selected an option).
From the scriptaculous doc, I figured out
''afterUpdateElement'' is the
place to be but I wonder if/how and where I can hook my javascript code
to this event in Rails code (I''d like to keep using the helper, if
possible)?
I tried passing many variations of
:after_update_element=>
"alert(''after_update_element action'')"
in _text_field_with_auto_complete_ and _auto_complete_field_ to no avail.
Any hint?
TIA

(SOLVED) Re: autocompletion: hooking ''afterUpdateElement'' in Rails
There''s already a tiny patch in the waiting list that solves that very
problem:
http://dev.rubyonrails.org/ticket/3691
[PATCH] Add frequency and afterupdateelement option to
text_field_with_auto_complete
It justs adds 2 lines in the _auto_complete_field_ method
(java_script_macros_helper.rb)
js_options[:frequency] = "#{options[:frequency]}" if
options[:frequency]
js_options[:afterUpdateElement] = "function(element,value) {
return #{options[:after_update_element]}(element,value); }" if
options[:after_update_element]

I''ve added this to the rails trunk, but slightly altered the proposed patch, (see the comment on #3691).

Anybody? How does one call a remote_function with after_update_element ?

Re: Re: (SOLVED) Re: autocompletion: hooking''afterUpdateElement'' in Rails
This should work (haven''t tested it):
:after_update_element =>
"function(element,value){" + remote_function(:url => { :action
=> :update_city_zips }, :with
=>"''selected_city_name=''+element.value") +
"}"
If it doesn''t, drop by in #prototype on freenode.net (today!) so we
can have a look.

It worked fine. Many thanks.

i took the prototype and all the scriptaculous .js files and combined them into one, then i ran it through the compressor at http://www.creativyst.com/Prod/3/ it was able to compress it down about 77%. what i am wondering is, is this safe to use? i am just looking to chop down the 152kb of all the .js combined.
I just tried the compressor, it compressed the files _to_ 77% of their original size. I compared this to GZIP by compressing prototype.js, 47603 bytes, down to 10632 bytes, so that might be a better choice. - David Am 07.04.2006 um 21:52 schrieb Louis Walch:> i took the prototype and all the scriptaculous .js files and > combined them > into one, then i ran it through the compressor at > http://www.creativyst.com/Prod/3/ > > it was able to compress it down about 77%. what i am wondering is, > is this > safe to use? i am just looking to chop down the 152kb of all the .js > combined. > _______________________________________________ > Rails-spinoffs mailing list > Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs >
Thanks for the link, I just tried it out. It seems to take out whitespaces and comments, but is not "intelligent" Is anybody aware of a JS compressor which ofuscates by replacing variables with short-named versions (just one letter) ?

I get that same compression using mod_gzip (or gzip compression & caching in the application). -- Bill Moseley moseley-kv6DSSSScSo@public.gmane.org
One word: gzip This provides: 1. Much better compression ratios 2. It doesn''t mess with the JavaScript 3. You still get decent messages if JavaScript errors should happen 4. It''s completely transparent to both your application and the browser Implementation depends on the webserver, of course. Apache has mod_gzip and mod_deflate, and lighttpd comes with mod_compress. -Thomas Am 07.04.2006 um 21:52 schrieb Louis Walch:> i took the prototype and all the scriptaculous .js files and > combined them > into one, then i ran it through the compressor at > http://www.creativyst.com/Prod/3/ > > it was able to compress it down about 77%. what i am wondering is, > is this > safe to use? i am just looking to chop down the 152kb of all the .js > combined. > _______________________________________________ > Rails-spinoffs mailing list > Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs
