console.log 不会将消息打印到 firebug 控制台？

Question

I am facing this weird problem. The WebApp I'm debugging right now, is invoking the javascript console.log/console.log/error/debug/etc., the Firebug console however, doesn't print them at all. This application uses Dojo/Dijit toolkit. Not sure if there is anything special about it

It doesn't appear to be a problem with the Browser, I tried another simple web-page with a console.debug call, and the message appears on the console as expected.

Please advise about what should I look for. I have also tried Chrome/IE.

Thanks in Advance/

Answer 1

console is not write protected, it can be replaced with anything. You could try

alert(console.log.toString());

to find out what console.log really is

Edit:

A better method would be

var originalConsole = console;
// now include your library
// ...
originalConsole.log(console.log);

In Firebug, clicking on the function takes you directly to its definition.

Answer 2

did you try window.console.log() ? Maybe you are not in window scope

Answer 3

In case like this do not forget to check if "Logging" is enabled or active at your console of browser.

Answer 4

Just to update this question -: Ensure that firebug is Enabled - - > On for all Web Pages. Reload the application. Then in the firebug panel - - > Console - - > All. All the console.log messages will appear.
