mw.Title(title, namespaceopt)

Library for constructing MediaWiki titles.

Example

new mw.Title( 'Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Template:Foo'
mw.Title.newFromText( 'Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Template:Foo'
mw.Title.makeTitle( NS_TEMPLATE, 'Foo' ).getPrefixedText();
// => 'Template:Foo'

new mw.Title( 'Category:Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Category:Foo'
mw.Title.newFromText( 'Category:Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Category:Foo'
mw.Title.makeTitle( NS_TEMPLATE, 'Category:Foo' ).getPrefixedText();
// => 'Template:Category:Foo'

new mw.Title( 'Template:Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Template:Foo'
mw.Title.newFromText( 'Template:Foo', NS_TEMPLATE ).getPrefixedText();
// => 'Template:Foo'
mw.Title.makeTitle( NS_TEMPLATE, 'Template:Foo' ).getPrefixedText();
// => 'Template:Template:Foo'

Constructor

new mw.Title(title, namespaceopt) #

Parse titles into an object structure. Note that when using the constructor directly, passing invalid titles will result in an exception. Use newFromText to use the logic directly and get null for invalid titles which is easier to work with.

Note that in the constructor and newFromText method, namespace is the default namespace only, and can be overridden by a namespace prefix in title. If you do not want this behavior, use makeTitle.

Parameters:

Name Type Attributes Default Description
title string

Title of the page. If no second argument given, this will be searched for a namespace
namespace number <optional>
 NS_MAIN

If given, will used as default namespace for the given title
Source:

Throws:

When the title is invalid

Type
Error
Parse titles into an object structure.
