Populate email fields in default email client - JavaScript.

prepareEmail.js

// **prepareEmail(to, subject, body)**  
// This comes in handy when attempting to obfuscate email address to prevent scrapers from grabbing them.  
// This will take an email address, subject and a body and submit a form to the mailto: protocol, which should open up the default email client and populate the to, subject and body.  
// For more information about what this does see http://support.microsoft.com/kb/279460.
// - *to* {String} - 'TO' e-mail address 
// - *subject* {String} - subject line
// - *body* {String} - e-mail's body
function prepareEmail(to, subject, bodyText) {
	var form = document.createElement('form');
	
	//Set the form attributes 
	form.setAttribute('method', 'post');
	form.setAttribute('enctype', 'text/plain');
	form.setAttribute('action', 'mailto:' + escape(to) + '?Subject=' + escape(subject) + '&Body=' + escape(bodyText ? bodyText : ' ') );
	form.setAttribute('style', 'display:none');
	
	//Append the form to the body
	document.body.appendChild(form);

	//Submit the form
	form.submit();
	
	//Clean up
	document.body.removeChild(form);
}
