*** WTH is it? ***

When the user hovers over a mailto link, they are given the option to compose 
an email in one of three popular webmail services, Gmail, Yahoo, or Hotmail, 
instead of in their default mail client. 


*** Dependencies ***

1) jQuery 1.4
2) Availability of direct links to compose windows in Gmail, Yahoo, and Hotmail.


*** Known Bugs ***

1) Sometimes the webmail compose window doesn't completely load. This happens
   most often with Yahoo. I don't think I have much control over this, 
   so it's unlikely to be addressed.
2) Hotmail bcc does not work. No idea why.


*** How to Use the Webmailto Plugin ***

First make sure to include jQuery and the plugin inside your <head/> tag:

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://github.com/kevin-cantwell/webmailto/raw/master/jquery.webmailto.js" type="text/javascript"></script> 

Then you can call webmailto on link tags in the normal jQuery way:

    <script type="text/javascript">
      $(document).ready(function() {
          $('a').webmailto();
      });
    </script>

Hovering over any matched elements will cause an absolutely positioned list 
of webmail links to appear underneath. If the selector matches a link tag which 
is not a mailto link, or if the tag is not a <a/> tag, then it is silently ignored. 
In the above case, all mailto links on the page would be matched.


*** "Features" ***

Webmailto does not apply any default styling. However, you can define your own 
styles by implementing the webmailto class or by passing css into the plugin as 
optional parameters.

Implementing the webmailto class:

    <style type="text/css">
      ul.webmailto {
        list-style       : none;
        margin           : 0;
        padding          : 0;
        background-image : url('img/webmails.png');
      }
      ul.webmailto li {
        display          : inline;
      }
      ul.webmailto li a {
        margin           : 0;
        display          : inline-block;
        text-indent      : -9999px;
        width            : 50px;
        height           : 50px;
      }
    </style>

Passing in your own css class to the plugin to achieve multiple stylings:

    <script type="text/javascript">
      $(document).ready(function() {
        $('a.default').webmailto();
        $('a.meh').webmailto( { className : 'mediocre-css' } );
        $('a.exciting').webmailto( { className : 'awesome-css' } );
      });
    </script>

    
*** Handle to New Window ***

Webmailto can provide you a handle to the newly opened window via a callback
function:

    <script type="text/javascript">
      $('a').webmailto( 
        { 
          className : 'custom', 
          callback  : function(newWindow) {
            // This may not work well in IE, sorry...
            newWindow.confirm('Destroy the warp core?');
          }
        } 
      );
    </script>
