'''Notes'''
−
 
+
* '''url''' is mandatory, the rest is optional (leave out interval to make the data static).
 +
*: it also must be written without protocol since colon (''':''') is not allowed, and may be relative, for example: ''//ackspace.nl/spaceAPI/'' or ''/spaceAPI/''
 +
* You must provide a unit for the sizes (i.e. px, %, etc.)

This widget allows you to display the Space API data (provided as JSON)

Created by Xopr

Using this widget

To insert this widget, use the following code: 

{{#widget:SpaceAPI
|url=/spaceAPI/
|width=260px
|height=300px
|padding=8px
|interval=20
|float=right
|features=beacon,annex
}}

This will give the following result:

Notes

  • url is mandatory, the rest is optional (leave out interval to make the data static).
    it also must be written without protocol since colon (:) is not allowed, and may be relative, for example: //ackspace.nl/spaceAPI/ or /spaceAPI/
  • You must provide a unit for the sizes (i.e. px, %, etc.)

Copy to your site

To use this widget on your site, just install MediaWiki Widgets extension and copy full source code of this page to your wiki as Widget:SpaceAPI article.
