[Dynapi-Dev] A handy DEBUG method

[Ramon B. <ram...@f5...>]

Hi

I'm not too sure how people DEBUG javascript
But I have found this very handy but I am sure your
mileage may vary.

It removes the need for using the 'alerts' left, right and everywhere

The only drawback is before a refresh of the Calling page, 
you have to close this window also
(maybe set an onReload .. (close DEBUG window)


Anyways call it as such

var DEBUG = 1
...
if (DEBUG) doDEBUG('layer1 has loaded')


----------------------------------
function doDEBUG (str) { 

	if(!window.DEBUGWindow) { 
		window.DEBUGWindow = window.open("", "DEBUG", "width=300,
height=400");
		// force the setting of the new windows parent
		if(!window.DEBUGWindow.opener) window.DEBUGWindow.opener =
self
		window.DEBUGDynDoc = new DynDocument(window.DEBUGWindow)
		window.DEBUGDynDoc.setBgColor('#fff6f6')
		window.debugIT = new DynLayer()
		window.DEBUGDynDoc.addChild(window.debugIT)
	}
	window.debugIT.setHTML(window.debugIT.getHTML() + str + '<br>')
	window.debugIT.setSize(300,window.debugIT.getContentHeight())

}

I've got an alternative method that caches the errors until everything has
loaded and generates a error output page.  It can also be told to display
javascript errors or even catch and not display javascript errors.

DynAPI {
    errors : [],
    displayerrors : false, // indicates if you wish all errors to be caught or
sent to the in-built js console
    errorHandler : function (msg, url, lno) {
        DynAPI.errors[DynAPI.errors.length] = [url,lno,msg];
        // if the page has already loaded, errors will be alerted instead of
sent to the debug page
        if (DynAPI.loaded&&DynAPI.displayerrors)
            alert("Error in '" + url + "'.\nLine number: " + lno +
".\nMessage: " + msg);
        return DynAPI.displayerrors;
    },

// The following line is added at the end of the loadHandler:
if (DynAPI.errors.length&&DynAPI.displayerrors) DynAPI.errorOutput();

// The following line is added at the end of the dynapi.js
onerror = DynAPI.errorHandler;

I have been doing something very similar. I have thought about taking it to
the next level and making it so that errorHandler actually sends the message
(url,lno,msg) to me (the developer) via e-mail in the background, but
returns true to the application so that the user is unaware that an error
occurred. This way once the application is deployed I can keep a pulse on
errors in the real world and take care of errors missed in the testing, yet
the user is not hindered since all of this notification happens in the
background.

Any thoughts on implementation?

Jim

AFAIK it only works with server side technology, and you would have to tell
the user this happens, or they'd think it's spy-ware.

Apart from that I think I would implement it on my site, saving results to a
database, including the users browser and platform.

Cheers,

Re: [Dynapi-Dev] A handy DEBUG method

[Doug M. <do...@cr...>]

very good idea..
There are only two ways to go about it tho (That I know of),
one would be a dialog "Do you wish to send a debug report?"
if they answer yes, then bring up their email client (mailto:ar...@ar...)
OR
you would have to use a server side component of some sort..
I have an 'email us' form on some of my client site which use
IIS and ASP to send the message via the server:

The following code is the asp (server side) code to send an email.
Note: You need to have SMTP installed on the NT/win2k server.

<%
  Dim MyMail
  Set MyMail = Server.CreateObject("CDONTS.NewMail")
  MyMail.From = de...@de...
  MyMail.To = ar...@ar...
  MyMail.Subject = "an error report"
  MyMail.BodyFormat = 1    'text?
  MyMail.MailFormat = 1
  MyMail.Body = "Error message..."
  MyMail.Send
  Set MyMail = Nothing
  response.redirect("thankyou_home.html")

%>
