Syntax

GM_log( message, level )

Description

Allows script authors simple access to logging informational messages in the Error Console. This can be helpful for debugging.

The message string is required.

The level is optional and defaults to 0. Valid values are:

GM_log("Hello, World!");
GM_log("Warning, " + someInputField.value + "!", 2);

GM_log is available in Greasemonkey version 0.3 and later.

Since Firebug 1.0, extensions.firebug.showChromeMessages must be set to true for GM_log messages to show up in the Firebug console.
