Description Wiredtape 2007-06-03 18:09:45 UTC
The problem I am trying to address is topics that have multiple "choices" in them..
A good example is a Drivers License; Drivers Licenses have different laws\regulations\classes and vary by geographical locations, classes, and the type of vehicle.

The solution:
Create an extension that gives the user a selection list, once a selection is made, an xmlHttpRequest() can go and fetch the "text" relevant to that selection...

so for instance:
if I choose United States in the selection list. I will get information relevant to Drivers Licenses in the United States...

A simple extension format for this could be:

<droplist ext="drivers_license>value1,value2 etc.</droplist>

ext would define the url information for xmlhttprequest -> meaning you would combine the two strings valuex and ext and get value1_ext and that would be the name of the article for xmlhttprequest.. the values would be the selection options of course...

I don't have a lot of experience with php or ajax, but I started to write something for the extension:

<script window.onload=makeList() type="text/javascript">
var x
	// Get the list of options from $list
function makeList() {
x= "<?php echo $alength;?>";
       for (i=1;i<x;i++) {
                 opt = document.getElementById('dlist');
				 newOpt=new Option("<?php echo $list[i]?>"); // 1st argument is the text to show, 2nd is the value for it if any
                 opt.options[x]=newOpt;   // adds it
function incart(art) {
	var xmlHttp

 if (xmlHttp==null)
  alert ("Browser does not support HTTP Request")
 var url="<?php echo $argv["ext"]?>
function GetXmlHttpObject()
var xmlHttp=null;
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
catch (e)
  // Internet Explorer
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
  catch (e)
    xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
return xmlHttp;
<select name="list" id="dlist" onchange=incart(this.options[this.selectedIndex])>
<option value="">--- choose below ---</option>

# Droplist WikiMedia extension
# Attributes that are sent to the extension include:
# Option list, and the attached url ending.

$wgExtensionFunctions[] = "wfDroplist";

function wfDroplist() {
    global $wgParser;
    # register the extension with the WikiText parser
    # the first parameter is the name of the new tag.
    # In this case it defines the tag <example> ... </example>
    # the second parameter is the callback function for
    # processing the text between the tags
    $wgParser->setHook( "droplist", "renderDroplist" );

# The callback function for converting the input text to HTML output
function renderDroplist( $input, $argv, &$parser ) {
    $list = explode(",",$input);
	$alength = count($list);

Comment 1 Malafaya 2009-02-07 00:16:36 UTC
Just to make sure: does this apply to extension Wikidata?
Comment 2 Andre Klapper 2012-11-01 15:05:06 UTC
WiredTape: Which environment (setup; extension) does this refer to?
Comment 3 Malafaya 2012-11-09 14:20:40 UTC
This was set as OmegaWiki but I don't see any relation between what is presented and OmegaWiki.
Comment 4 Andre Klapper 2012-11-12 11:26:08 UTC
Malafaya: The old extension with the name "wikidata" is part of OmegaWiki.
Comment 5 Malafaya 2012-11-13 21:31:30 UTC
Sure, but the request presented by the submitter doesn't seem to have anything to do with either OmegaWiki or old Wikidata.
Comment 6 Andre Klapper 2013-04-05 15:21:14 UTC
Unfortunately closing this report as no further information has been provided.

Wiredtape: Please feel free to reopen this report if you can provide the information asked for and if this still happens. Thanks!
