使用法

タグ

To choose between one or more options, simply place each option inside an ‎<option> tag which are themselves placed inside ‎<choose> tags, like so:

<choose>
<option>This is the first choice.</option>
<option>This is the second choice.</option>
<option>And so on...</option>
</choose>

From each set of ‎<choose> tags, precisely one ‎<option> tag will be selected at random, and its contents shown. Anything can be placed inside of option tags: links, images, even templates.

However, that template arguments will not be expanded due to タスク T4257.

You can also have what is placed inside the option tags be sent as an argument to a template with the ‎<choicetemplate> tag, e.g.:

<choose>
<option>Template:Featured article/Elephant</option>
<option>Template:Featured article/Giraffe</option>
<option>Template:Featured article/Rhinoceros</option>
<choicetemplate>PageWithEditButton</choicetemplate>
</choose>

You could then create a [[Template:PageWithEditButton]] with these contents:

[{{canonicalurl:{{{1}}}|action=edit}} Edit] {{{{{1}}}}}

This is useful if you want to set up randomly rotating featured articles and have an edit button to allow the user to edit the featured article blurbs.

Parameters to ‎<choose>

パラメーター 説明
uncached Disable caching for the chosen option
before Put this text before the chosen option
after Put this text after the chosen option
Since version 2.2.2 caching in the ‎<choose> tag is disabled only if the user specifies ‎<choose uncached>. Previously caching was disabled by default.

If you wanted to disable caching for the options, you should add the uncached parameter.

<choose uncached>
<option>This is the first choice.</option>
<option>This is the second choice.</option>
<option>And so on...</option>
</choose>

If you wanted to display one of three YouTube videos, you could try this (Extension:Widgets and Extension:YouTube required):

<choose before="{{#widget: YouTube|id=" after="}}">
<option>eR7-AUmiNcA</option><!--King of Anything-->
<option>cSCi7kCXKDA</option><!--Slipping Through My Fingers-->
<option>7n2d9XPsmmE</option><!--When Death Note Music Plays in My Car-->
</choose>

Parameters to ‎<option>

パラメーター 説明
weight Weight of the option

If you'd like some options to be shown more often than others, you can add weight to the option tags, like so:

<choose>
<option weight="2">This option will be shown twice as often as a normal option.</option>
<option>By default, options have a weight of 1.</option>
<option weight="1.5">This option also has a weight of 1. Fractional portions are ignored.</option>
</choose>

パーサー関数

To choose between one or more options, simply place each option inside the #choose: parser function, like so:

{{#choose:
 |This is the first choice.
 |This is the second choice.
 |And so on...
}}

From each choice divided by a pipe, precisely one choice will be selected at random, and its contents shown. Anything can be placed inside: links, images, even templates.
