/* Plugin: safe_mail
* Author: Michael D. Risser <MDRISSER AT the domain called GMAIL which is a dot COM>
* Date: October 2007
*
* Description:
*		With the proliferation of spammers out there, scrapping email addresses off of web sites,
*		this plugin for jQuery makes it easy to hide email address from spam bots.
*		
*		The plugin is far from perfect, but it works, although I plan to expand on it as time permits.
*		Usage is pretty straight forward, as shown below. The only caveat is that you need an element to
*		append the mailto link to. You can simply place an empty div or span where you want the email link to
*		appear, and access it using the id you have provided. For example:
*			<p>Here is a bunch of text in a paragraph, where I want an <span id='email_link'></span> to
*			appear. Since the plugin appends to an element, I've included an empty span tag where I want
*			the email address to appear.</p>
* Usage:
*		To use the email address as the link text:
*			$('#email_link').safe_mail("john.doe", "domain", "com");
*			Ouput: <a href="mailto:john.doe@domain.com">john.doe@domain.com</a>
*
*		To use some other text as the link text:
*			$('#email_link').safe_mail("john.doe", "domain", "com", "This is my email link text");
*			Ouput: <a href="mailto:john.doe@domain.com">This is my email link text</a>

jQuery.fn.safe_mail = function(username, domain_name, domain_ext, link_text) {

    } else {
        link_txt = "link"
    }

    // If no link text(link_txt) is specified, or if the user explicitally sets link_txt to "link"
    if (link_txt == "link") {
        // Use the link its self as the link text
        mail_link = "<a " + "href" + "=" + "'mail" + "to" + ":" + username + "@" + domain_name + "." + domain_ext + "'>" + username + "@" + domain_name + "." + domain_ext + "</a>";
    } else {
        // Otherwise use the user provided link text
        mail_link = "<a " + "href" + "=" + "'mail" + "to" + ":" + username + "@" + domain_name + "." + domain_ext + "'>" + link_txt + "</a>";
