This jQuery plugin send an email when a javascript error is triggered. Specially useful in big web application where you want to know if users hit javascript errors.
A php mail example is given with this plugin, but it could also be easily logged in a database
Load the plugin just after the jQuery library
$(document).jsErrorHandler();
You can define some options.
By default the plugin automatically fetch the domain and add it to the email subject, but you can overwrite it. You can also define a from, I would highly recommend that you change the from setting in the plugin file (jquery.onerror.js) if your going to use this plugin on multiple websites.
$(document).jsErrorHandler({
from: "support@youremail.com",
website: document.domain
});
The email received will look like this:
A javascript error has been detected on www.position-absolute.com
Message: variable is not defined
Url: http://www.position-absolute.com/creation/onerror/
Line: 21
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0
The plugin works on Firefox 3.6+, Chrome Latest, IE7+
It does not work on Safari and Opera, but it will not break your application.
