'console' is undefined error for Internet Explorer

Question

I\'m using Firebug and have some statements like:

console.log(\"...\");

in my page. In IE8 (probably earlier versions too) I get script err

Answer 1

For IE8 or console support limited to console.log (no debug, trace, ...) you can do the following:

• If console OR console.log undefined: Create dummy functions for console functions (trace, debug, log, ...)

  window.console = { debug : function() {}, ...};

• Else if console.log is defined (IE8) AND console.debug (any other) is not defined: redirect all logging functions to console.log, this allows to keep those logs !

  window.console = { debug : window.console.log, ...};

Not sure about the assert support in various IE versions, but any suggestions are welcome. Also posted this answer here: How can I use console logging in Internet Explorer?
