|fname12 = IF(cond) |ftype12 = boolean |fuse12 = Allows for if-blocks without breaking the chain. If the condition is true it is a no-op, if false everything inside the balanced IF-END block will be ignored. Can be nested. Ex.: <syntaxhighlight lang="lua"> mw.html.create('div')
:IF(true) :wikitext('Conditional text') :END() :...
</syntaxhighlight> Note: This only prevents elements from being added to your html object, it does not protect against statements that throw errors. I.e <syntaxhighlight lang='lua'> mw.html.create('div')
:IF(false) :wikitext(5 * nil) -- This will still throw an error :END()
</syntaxhighlight>
|fname13 = ELSEIF(cond)
|ftype13 = boolean
|fuse13 = Used together with IF()
.
|fname14 = ELSE()
|ftype14 = N/A
|fuse14 = Used together with IF()
.
|fname15 = END()
|ftype15 = N/A
|fuse15 = Used together with IF()
. Make sure the IF-END tags are balanced, it wont throw an error if they are not.
|fname16 = exec(func, ...) |ftype16 = function, any |fuse16 = Call a function without breaking the chain. See module docs for more info.
|fname17 = addFunction(func, name) |ftype17 = function, string |fuse17 = Add a function to the mw.html class that can then be used on mw.html object. See module docs for more info. }}
Usage
For all functions other than addFunction()
all you need to do is simply require this module:
<syntaxhighlight lang="lua">
require('Module:Mw.html extension')
local p = {}
function p.main()
... local tbl = mw.html.create('div') :IF(true) :wikitext('Conditional text') :ELSE() :wikitext('something else') :END() :addClassIf(true, 'wikitable') :tag('span)' :wikitext('normal wikitext') :done() ...
end
return p </syntaxhighlight>
You can mix the normal old functions with the newly added ones.
attrIf
This accepts either a name-value pair or a table
:attrIf(true, 'data-sort-value', '0')
:attrIf(true, {'data-sort-value' = '0', ...})
cssIf
This accepts either a name-value pair or a table similar to attrIf
exec
The first parameter of the function will have the current state of the mw.html object passed into it, usually we call this parameter self
, the rest of the parameters can be anything you want. To not break the chaining the function must also return a mw.html object. Example:
<syntaxhighlight lang="lua">
local function repNa(self, times)
for i = 1,times do self:na() end return self
end </syntaxhighlight>
This function can then be used as follows <syntaxhighlight lang="lua"> mw.html.create('div'):exec(repNa, 5) </syntaxhighlight>
addFunction
The function you want to add has to be of the same structure as in exec()
. Example:
<syntaxhighlight lang="lua">
local htmlExtension = require('Module:Mw.html extension')
local p = {}
local function repNa(self, times)
for i = 1,times do self:na() end return self
end htmlExtension.addFunction(repNa, 'repNaName')
function p.main()
... local tbl = mw.html.create('div'):repNaName(5) ...
end
return p </syntaxhighlight>
tr, th and td
The following three tables are the same: <syntaxhighlight lang='lua'> local tbl = mw.html.create('table') tbl:tr{ class='sortable' }
:th{'foo', attr={['data-sort-type']='number'}} -- or attr={'data-sort-type', 'number'} :th('bar') :IF(expression) :addClass('table-na') :END() :tr() :td('buz') :td{'N/A', class='table-na'}
local tbl2 = mw.html.create('table') tbl2:tag('tr')
:addClass('sortable') :tag('th') :attr('data-sort-type', 'number') :wikitext('foo') :done() :tag('th') :wikitext('bar') :IF(expression) :addClass('table-na') :END() :done() -- This is needed because "tag('tr')" is used after this instead of "tr()" :done() :tag('tr') :tag('td') :wikitext('buz') :done() :tag('td') :wikitext('N/A') :addClass('table-na')
local tbl3 = mw.html.create('table') tbl3:tag('tr')
:addClass('sortable') :tag('th') :attr('data-sort-type', 'number') :wikitext('foo') :th('bar') :IF(expression) :addClass('table-na') :END() :done() :done() :tag('tr') :td('buz') :td('N/A') :addClass('table-na')
