Frequently asked questions
Q.How long will it take me to install?
A.It depends on the website you are installing it on. The installation simply requires the addition of a single line
of code immediately after the <head> tag on every page. If your website is static html, then you can probably run a find and replace using your preferred
editing tool, which should allow you to be up and running in around 5-10 minutes. If you are running a dynamic website the easiest thing would probably to
write some server side code to inject the script immediately after the head tag.
Q.Will people visiting my website know we are using Erroralerts?
A.No not unless they look in your source code.
Error alerts silently sends reports of any script errors in the page, back to our servers using client side javascript.
Q.Will ErrorAlerts work on all browsers?
A.ErrorAlerts currently works in Internet Explorer 5.5 or greater, and Mozilla Firefox version 1 or greater.
This effectively covers the vast majority of current web users. Limitations in the way Safari handles javascript errors, mean errors generated by
people using Safari will not be recorded.
Q.Why does the line number reported not appear to be related to the actual error
A.Internet Explorer which is currently the most commonly used browser does not reliably report the line
number that an error occured at in relation to the source code. The line number reported is related to Internet Explorer's own internal rendering of
your code, so differences can occur. It is possible that the line number may relate to a line in a referenced script file, or to a different location
in the file, sometimes a line after the line reported. We report the line number exactly as it is reported by the browser used.
Firefox reports the location of the error more reliably, reporting the script file that an error occured in where applicable.
Firefox will not however provide you with details about the element that caused the error, known as the "caller", this information can be useful in
quickly tracing the cause of an error, and is currently only provided by Internet Explorer.
Q.Why should I use ErrorAlerts?
A.It's true you could log javascript errors yourself, but ErrorAlerts offers much more than just that. You can optionally
choose to receive email notifications of new errors. You can use our unique interface to help you debug the root cause of the error easily.
The system also allows you to effectively group the errors that have occured, all things that help you to understand what caused the problem
in the first place. You need host nothing extra on your own servers, there's nothing to install (other than adding the script file to your pages)
and our service is free!
