Rails spinoffs - Feb 2006 - Length of parameters in Autocompleter.Local()

Hi,
  I''m using PHP to fill my parameterlist for Autocompleter.Local as 
shown in the example 
(http://wiki.script.aculo.us/scriptaculous/show/Autocompleter.Local).

<script type="text/javascript">
new Autocompleter.Local(''recipeNameAlternative'',
''rezept_list'', [
<?php $ende = count($rezept_vorgabe);
  for ($i=0;$i<$ende;$i++) {
	echo
''\''''.$rezept_vorgabe[$i].''\'''';
	if($i != $ende-1) {
		echo ",";
	}
  } ?>
], {});
</script>

If the content of $rezept_vorgabe is over 30 elements long, my 
JavaScript-Console returns the error "missing ] after element list".
AutoCompletion will not work!?

Can someone give me a hint?

Do you have a live site we can look at?  Do any of your elements
contain a ''?  It would need to be escaped (\\\'').

something is probably wrong with one of the elements in the list.

instead of blindly writing out the array, you might want to find a php JSON 
module or extension or function or whatever, and you just generate an array, 
convert it to json, and drop it in there.  Then you can be certain (unless 
the JSON creation is buggy) that the array will work.

I currently use the perl JSON module for a similar function, and I often have 
thousands of elements in the array without problems.

If you aren''t down for that, then I am with Todd that we need to see
the
output of the php code you have shown us.  I''m not good enough with php
to be
able to think of an example where your code would produce broken javascript, 
but I''m almost certain that''s what''s happening.

okay, i can. http://lekapidia.ml-its.de/formtest/test.php

I change
''\''''.$rezept_vorgabe[$i].''\''''
to "''".$region_vorgabe[$i]."''" in
PHP, but no Changes.

thanks for more help

Your PHP-built list has quotes in it which is breaking the JS.

Try:

''\''''.str_replace("''",
"\\''", $rezept_vorgabe[$i]).''\''''

Also you know you can loop through an array with 
http://www.php.net/foreach ?

<?php
$array = Array("foo", "bar", "baz",
"boo");
foreach ($array as $value) {
	echo $value."\n";
}
?>

Prints:

foo
bar
baz
boo

You should use the JavaScript console in Firefox 1.5, it alerts you to 
errors like this.

I discovered your error by using a syntax highlighting editor such as 
Gvim (http://www.vim.org).

there are no '' in $rezept_vorgabe[$i]. i add the in the loop(PHP), see
	for ($i=0;$i<$ende;$i++) {
		echo "''".$region_vorgabe[$i]."''";
	}

I have used it for a long time. The error "missing ] after element
list"
is out of it.

I''m using Dreamweaver, so my syntax highlighting works well.

You are mistaken.

''Costa Rica'',
''Cote d''Ivoire'',
''Daenemark''

d''Ivoire needs to be escaped d\''Ivoire

you need to escape that inner single quote.  Again, I would recommend using 
some sort of json module to handle this for you.

I think that''s a bit overkill. My fix should work fine for anything
that
doesn''t include newlines. If this were my application I''d dump
the data
in a hidden <ul><li> or maybe as an xml string and parse it with the
built-in DOM parser. Much better parse something in XML than *shudder* 
javascript. JS shouldn''t be used for heavy data processing because it 
burdens the client (IMO).

Really? I would think that XML parsing in JS is much more burdensome than a
native format. Would you replace all of you JS hashes with XML?

Hm I may be mistaken. AFAIU JSON is a JS-compatible serialization form? 
Do browsers have built-in JSON deserializers?

My the way, you''d be surprised at how efficient XML parsers are. In 
Python, it''s quicker to decode a list from XML than using the Pickle 
module (which is equivalent to PHP serialize()). IE probably even parses 
XML in kernel space, but that''s only a guess.

Um no, I mean can you convert a JSON object into a memory construct 
without parsing it with Javascript code. Hence, is there a built-in JSON 
deserializer (that isn''t written in JavaScript). As far as I am aware, 
JSON isn''t part of the javascript language specification.

-Rob

No, but from I understand (don''t use JSON myself), it translates
directly into Javascript objects when eval''ed.

var myObj = eval(myJSONstring);

Oh I see. How interesting. Eval scares me heh. Well in which case you''d
have to unit-test JSON vs XML to see which would be quicker. I have a 
feeling it''d be close though, and I know which one I''d pick if
that was
the case.

thanks to all of you! this sign was the seed of all evil.

move it into an JS-Array helped to solve it

var temp_rezept_array = new Array(<?php echo count($rezept);?>);
//Schleife
<?php
for ($i=0;$i<count($rezept);$i++) {
     echo "temp_rezept_array[".$i."] =
\"".$rezept[$i]."\";\n";
}
?>

errr....

no, I meant for him to take his php array, let''s say it''s
this:
$something = array ("bob", "larry", "frank");

then pass it to a JSON serializer, which will return a string, something like 
this:
[''bob'', ''larry'', ''frank'']

then drop that string in place where he currently has the broken javascript 
array.  The advantage is, he doesn''t have to think about the escaping
of
strings and such, because the JSON serializer does it for him.

I use this technique a lot in my own code for building an array/hash in perl 
and then ''converting'' it to javascript and dropping it inside
a <script> tag.

no need to eval, he''s already printing this string into the page where
he
wants the javascript array to be, all the json module I was referring to 
would do would be to convert his array into the string he needs.

Essentially, it would do what he''s already doing, but better.

No need for any json parser or whatever in the browser.

Take for example:
<script type="text/javascript">
var myarray =
[''bob'',''larry'',''frank''];
</script>

or a php example:
<script type="text/javascript">
var myarray = <?php
some_json_converter(array("bob","larry","frank"));
?>;
</script>

the above two should produce the exact same code to the browser, aside from 
maybe differences in whitespace.

Oh I see! Sorry. That seems, well, bloody interesting. I don''t do 
anything like this at the moment (all AJAX) but I will consider that for 
the future. I do need a way to encapsulate a load of HTML inside a JS 
string accurately. At the moment''s I''m just doing
search/replace
escaping of quotes and newlines.

yea, you could just find a JSON module for your programming language (I use 
perl''s JSON module, works great) and drop it in, voila.

for here''s some perl code:

#!/usr/bin/perl

use strict;
use JSON;

my @array = ("how", "are", "you",
"doing", "today");
print objToJson(\@array);

this outputs:
["how","are","you","doing","today"]

now if we make that array more complicated:
my @array = qw( how''re "you" doing today?
''"q/3\\#\${]}[ );
that outputs:
["how''re","\"you\"","doing","today?","''\"q/3\\#\\${]}["]

it automatically escapes everything for you.  If you already have the object 
created in whatever language you want, just use some sort of JSON module to 
convert it to javascript for you.  real easy :)

Nice. As I say, I don''t have a need to pass anything other than 
straight-up strings at the moment, but that certainly is worth remembering.

Cheers.

Isn''t that what eval() is?

Well, it''s not called JSON, but it is a part of the spec.

 eval( "{foo: 123, bar: 456}" );

As far as comparing it to XML -
