This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

HtmlBuilder provides a way to construct complex HTML and CSS markup by creating a tree of nodes, similar to the Document Object Model. The result is a list of codes that are more comprehensible and maintainable than if you simply concatenated strings together. It offers a fluent interface that should look familiar to any user of jQuery.

Note: This module is deprecated in favour of mw.html.

Usage

First, you need to load the module:

local HtmlBuilder = require('Module:HtmlBuilder')

Next, create the root HtmlBuilder instance:

local builder = HtmlBuilder.create()

Then, you can build HTML using the methods of the HtmlBuilder instance, listed below.

Finally, get the resulting HTML markup as a string:

local s = tostring(builder)

Methods

To allow chaining, all methods return a reference to the builder, unless otherwise stated.

tag

local div = builder.tag('div') Appends a new child node to the builder, and returns an HtmlBuilder instance representing that new node.

done

builder = div.done() Returns the parent node under which the current node was created. Like jQuery.end, this is a convenience function to allow the construction of several child nodes to be chained together into a single statement.

allDone

builder = div.allDone() Like .done(), but traverses all the way to the root node of the tree and returns it.

wikitext

div.wikitext('This is some [[example]] text.') Appends some markup to the node. It may include plain text, wiki markup, and even HTML markup.

newline

div.newline() Appends a newline character to the node. Equivalent to .wikitext('\n').

attr

div.attr('title', 'Attr value') Set an HTML attribute on the node.

css

div.css('color', '#f00') Set a CSS property to be added to the node's style attribute.

cssText

div.cssText('color:#f00; font-size:1.5em') Add some raw CSS to the node's style attribute. This is typically used when a template allows some CSS to be passed in as a parameter, such as the liststyle parameter of {{Navbox}}.

addClass

div.addClass('even') Adds a class name to the node's class attribute. Spaces will be automatically added to delimit each added class name.

Examples

local HtmlBuilder = require('Module:HtmlBuilder')

local root = HtmlBuilder.create()

root
    .wikitext('Lorem ')
    .tag('span')
        .css('color', 'red')
        .attr('title', 'ipsum dolor')
        .wikitext('sit amet')
        .done()
    .tag('div')
        .wikitext('consectetur adipisicing')

local s = tostring(root)
-- s = 'Lorem <span style="color:red;" title="ipsum dolor">sit amet</span><div>consectetur adipisicing</div>'
