Description

This template has to be use in parallel with toggling functions. It will only create the element that will be hidden/shown by the function.

Dipendenze

This template uses the following JavaScript codes:

/************* Funzioni di utilità generale *************/
 
 /* Test if an element has a certain class **************************************
 *
 * Description: Uses regular expressions and caching for better performance.
 * Maintainers: User:Mike Dillon, User:R. Koot, User:SG
 */
 
var hasClass = (function () {
    var reCache = {};
    return function (element, className) {
        return (reCache[className] ? reCache[className] : (reCache[className] = new RegExp("(?:\\s|^)" + className + "(?:\\s|$)"))).test(element.className);
    };
 })();
 
 
function getElementsByClass (node, className, tagName) {
	if (node.getElementsByClassName && (tagName == undefined || tagName == null || tagName == '*')) return node.getElementsByClassName(className);
	var list = node.getElementsByTagName(tagName?tagName:'*');
	var array = new Array();
	var i = 0;
	for (i in list) {
		if (hasClass(list[i], className))
			array.push(list[i]);
	 }
	return array;
 }
 
/* Creates the method getElementsByClass, if unsupported from the browser */
if(!document.getElementsByClass) document.getElementsByClass = function(className) {
	return getElementsByClass(document, className, '*');
};
 
 
function getElementsByName (name, root) {
 if (root == undefined) root = document;
 var e = root.getElementsByTagName('*');
 var r = new Array();
 for (var i = 0; i < e.length; i++) {
	if (e[i].getAttribute('name') == name) r[r.length] = e[i];
 }
 return r;
}

The codes must be placed in MediaWiki:Common.js.

Syntax

{{Toggle|default=|sost=|var=}}. Or if given as free parameters: {{Toggle|Valore di default|Valore da sostituire|Nome variabile}}.
The switch element must have this class (you can use a tag like this): <span class="_toggler-toto">Change</span>.

Parameters

1=/default= default text - optional.
2=/sost= alternative text - optional.
3=/var= element ID - avoid giving the same ID two different not-related switch elements.

Samples

Change a text with another through a link: {{Toggle|default=Default|sost=Alternative|var=switch1}} and

<span class="_toggler-switch1">Change!</span>

give:
Default
Change!

If the second parameter is null, then the text will be hidden:
{{Toggle|var=switch2}} and

<span class="_toggler-switch2">Hide</span>

give:
This text will be hidden
Hide

To change the contents with different links:

{{Toggle|text 1 (as first parameter is the default text)|var1}}
{{Toggle||text 2 (as second parameter is hidden by default)|var2}}

<span class="_toggler_hide-var2 _toggler_show-var1">link var1</span>
<span class="_toggler_hide-var1 _toggler_show-var2">link var2</span>

text 1

link var1 | link var2

Other

The "toggling classes" used by this template are: - "_toggle NAMEVAR": element NAMEVAR, the ID.
- "_toggler_hide-NAMEVAR": clicking on this element, NAMEVAR will be hidden.
- "_toggler_show-NAMEVAR": clicking on this element, NAMEVAR will be shown.
An element can have multiple classes.
