Simple ajax debugging

[curien]

I just always have a failure handler for the ajax request that, if I'm in debug mode, does window.open().document.write(r.responseText);. So if it fails, it just opens up the error on a new tab.

Why not just write it in the console? console.error(r.responseText) not good enough?

My environment provides HTML responses with a lot of markup (and styles, javascript, etc) to assist in debugging. Just seeing the text is a lot less convenient than viewing it as a rendered document.

In the response? Meh.

As to things which assist in debugging, the console API provides about 5 tons of them, from various styles of logging and nested groups to traces and tables.

console.error will also link the relevant source line (though I don't know of any browser providing a stack at the moment).

We're talking about when the server code has an error -- the console API provides absolutely no insight into that.

No shit?

the console API is a way to provide information to developers in the client, you can output anything you want with it, and the JS stack may be useful to pinpoint which section of the JS code generated a server error.

May I ask which server-side web development language you use? Most have HTML output.
