No Spam Email Image Link using AJAX
Web crawlers gather email addresses from your website that they then use to SPAM you. Web crawlers do this by reading the raw HTML to see if there are any email tags like a "mailto:".
With this method the email address isn't in the HTML so the web crawler can't capture it.
An email address get shown to a website visitor as an image in the HTML's <img> tag. The <img> tag then has an onclick event, when visitors click on the image an AJAX call fetches the email address (from a resource like a SOAP/RESTful web service) and then open the default email client.
The sample demostrates this method by calling a web service.
