zichun's autocomplete question

[eyik]

dear fellow members,

This is my first post in this forum, I hope for your guidances.

I recently uses autocomplete control from Zichun, a powerful autocomplete control used by youtube as well.

the autocomplete consist of two files:

actb.js

//////actb.js
function actbpro(obj, ca, hid, ids) {
      /* ---- Public Variables ---- */
      this.actb_timeOut = -1;
      // Autocomplete Timeout in ms (-1: autocomplete never time out)
      this.actb_lim =10;
      // Number of elements autocomplete can show (-1: no limit)
      this.actb_firstText = true;
      // should the auto complete be limited to the beginning of keyword?
      this.actb_mouse = true;
      // Enable Mouse Support
      this.actb_delimiter = new Array(';', ',');
      // Delimiter for multiple autocomplete. Set it to empty array for single autocomplete
      this.actb_startcheck =0;
      // Show widget only after this number of characters is typed in.

my problem: atm the autocomplete can only recognise more than one words when they are arranged consecutively in the result, example: when user input "apple bee" it only show result of "apple bee cat", "apple bee dog", "apple bee orange" and so on, but NOT "apple orange bee", "bee apple orage", etc

is there any solution for this?

any help will greatly appreciated.

[gits]

it's probably the actb_tocomplete() method that needs adaption - but hopefully you don't just want us to write the change for you? what have you tried so far?

regards

[eyik]

to be honest, I am also unsure what to look at.
I'm actually suspecting some modification at actb_parse because actb_tocomplete is more like button handler.

If anyone can give me hint so I know where to begin, it is a great first step.

meanwhile I will keep looking for clue myself

[uldisx1]

Ok, i need some help to. I use this drop down script, but i need to add width for drop down rows. How can i do that? I dont know much about .js, in css its simply, but not here... help!

[eyik]

Ok,seems that I found a dead end. Even worse, I'm not sure which function doing what.

could anyone can help me doing dissection on the code (as in understanding each function role)

[uldisx1]

Ok, i get answer.. if someone need to get drop down list width, than simply add

a.style.width='150px'; after " function actb_generate() " function :)

[uldisx1]

eyik maybe you can find answer here - http://www.codeproject.com/KB/scripting/jsactb.aspx there is some Q/A
