Module:Carousel: Difference between revisions

Module documentation[view] [edit] [history] [purge]

Carousel returns one of a list of image filenames.

The index of the one chosen increments every 'switchsecs', which is a parameter giving the number of seconds between switches.

• switchsecs=3600 would switch every hour
• switchsecs=43200 would be every 12 hours
• switchsecs=86400 would be daily (the default)

Usage

Generic:

• {{#invoke:carousel | main | name = name-of-data-module | switchsecs = number-of-seconds }}

Examples:

• {{#invoke:carousel | main }} for 24 hours between switches using default list
• {{#invoke:carousel | main | switchsecs = 10}} for 10 sec between switches using default list
• {{#invoke:carousel | main | name= | switchsecs = 1}} 1 sec between switches using default list
• {{#invoke:carousel | main | name=Komodobish | switchsecs = 5}} 5 sec using Komodobish's list
• {{#invoke:carousel | main | name=54129 | switchsecs = 43200}} 12 hours using Serial Number 54129's list

The image lists are at Special:PrefixIndex/Module:Carousel/, e.g. Module:Carousel/Komodobish for name=Komodobish.

Typically it will be used with standard image syntax:

• [[File:{{#invoke:carousel | main | name=Komodobish | switchsecs = 5}} | upright=1.25 | center | thumb | message goes here]] →
