console.log is only available after you have opened the Developer Tools (F12 to toggle it open and closed). Funny thing is that after you’ve opened it, you can close it, then still post to it via console.log calls, and those will be seen when you reopen it. I’m thinking that is a bug of sorts, … Read more
First you have to set this value on the application configuration file: <configuration> <appSettings> <add key=”log4net.Internal.Debug” value=”true”/> </appSettings> </configuration> Then, to determine the file in which you want to save the output you can add the following code in the same .config file: <configuration> … <system.diagnostics> <trace autoflush=”true”> <listeners> <add name=”textWriterTraceListener” type=”System.Diagnostics.TextWriterTraceListener” initializeData=”C:\tmp\log4net.txt” /> </listeners> … Read more

You can subclass HandleErrorAttribute and override its OnException member (no need to copy) so that it logs the exception with ELMAH and only if the base implementation handles it.

I think you’re looking for console.dir(). console.log() doesn’t do what you want because it prints a reference to the object, and by the time you pop it open, it’s changed. console.dir prints a directory of the properties in the object at the time you call it. The JSON idea below is a good one; you … Read more
You can do this using Network Tracing. To set it up, create (or modify, if you already have one) App.config file, so that it looks like this (if you already have the file, you will need to add the settings to it): <?xml version=”1.0″ encoding=”utf-8″ ?> <configuration> <system.diagnostics> <sources> <source name=”System.Net” tracemode=”protocolonly” maxdatasize=”1024″> <listeners> <add … Read more
If you’re running console.log() from a JS file, this undefined line should not be appended. If you’re running console.log() from the console itself, it makes sense. This is why: In the console you can type a name of a variable (for example try typing window) and it prints info about it. When you run any … Read more
To answer your first question… .format just seems more sophisticated in many ways. An annoying thing about % is also how it can either take a variable or a tuple. You’d think the following would always work: “hi there %s” % name yet, if name happens to be (1, 2, 3), it will throw a … Read more
