autocomplete problems

in Using jQuery UI • 3 months ago

im trying to implement the autocomplete in my asp.net website

everything seems OK, except for 1 problem

the select event fires only when i use "enter" on the keyboard.

selecting an item with the mouse does not trigger the "select"

this problem occurs only when selecting a non-ASCII text from the list

standard English text is OK either way

any ideas?

EDIT: after some more testing, this seems unpredictable, some times both ways work, other times only one. i cant say for sure its related to the Unicode text.

thanks

If your users are/will enter unicode characters, everything in the system has to be utf-8. For example, the top of the CSS page should state @charset "UTF-8"; , the HTML meta statement has to configure for utf-8, your php needs a utf-8 config statement, your text editor should be config'd utf-8. Apache. your database. You get the picture. Everything.

The select: function looks OK. Rather than val()==true, you might try .length >0

i'm not sure anymore its related to Unicode

i uploaded a test here

http://judaicasoftware.com/test.aspx

you can try searching for a city, the search always works, but when u select sometimes the id is filled in, sometimes not

sometime the problem is with clicking and sometimes with tab/enter

if it works for you every time try reloading the page

as i said its temperamental, can't find any pattern here

thanks for helping out

I tried your page and got a server error message page - no content, no Autocomplete. With a refresh, I got the same thing again. Maybe this portion of the error message will help.

Line 208:	Sub Trace(Text As String)
Line 209:		SqlDump.Add(Text)
Line 210:		Do Until SqlDump.Count <= 100
Line 211:			SqlDump.RemoveAt(0)

Source File: E:\web\judaicasoft\htdocs\App_Code\Classes\Misc.vb Line: 209

The rest of the error page (the bulk of it) was about asp stuff. I got the same error page in Chrome and Firefox 9.

Hello,

The returned array from your server is corrupted:

[{"id":326,"value":"newark"},

{"id":261,"value":"new sequare"},

{"id":261,"value":"new york, ny"},

{"id":261,"value":"new square"},

{"id":261,"value":"new york"},

{"id":261,"value":"new york ny"},

{"id":261,"value":"new sqare"},

{"id":261,"value":"new jersey"},

{"id":347,"value":"newville"},

{"id":261,"value":"new haven"},

{"id":333,"value":"monroe township, new jersey"}]

id 261 is used for different values.

Try to debug on your server the following script:

thank you

the ids for the test page are ad hoc numbers for testing

i simply cant disclose any production data, so i made an ad hoc list of cities with an arbitrary "id" based on the ASC values of the first 3 chars (that's why all the "NEW..." have the same "Id" :-))

does the autocomplete function expect unique ids as a prerequisite?

Autocomplete works with key, value pairs. Some of the keys in your array have multiple values, e.g, key 261 has 8 values in your example array. Though I have not studied the internals of Autocomplete, this can't be good. Just change your test array to have unique key value pairs.

i switched it to a "state" search, has less data, but now has unique ids

the problem, though persists, sometimes works, sometimes not.

thanks!
