Frontend: $wgAllowUserJs
Allow user JavaScript pages
Introduced in version:1.3.0 (r4194)
Removed in version:still in use
Allowed values:(boolean)
Default value:false (1.3.10+, r7357)
true (1.3.0-1.3.9)


Enables/disables user JavaScript pages. This enables a lot of neat customizations, but may increase security risk to users and server load.

A related setting $wgAllowUserCss allows/disallows users to use their own CSS files.


To enable users to perform their own JavaScript, append the following line to your LocalSettings.php file:

$wgAllowUserJs = true;

To disable this function set $wgAllowUserJs false or delete whole line.

Important note[edit]

Microsoft Internet Explorer and Mozilla/Firefox allow the embedding of JavaScript into stylesheets using HTC or XBL. So in order to prevent users from defining JavaScript, you need to disable $wgAllowUserCss as well.
