Open mailto links in GMail with Google Chrome, Firefox and maybe Safari.

Here is a simple bookmarklet that when clicked will turn all mailto: links on a webpage into javascript pop-up windows for a gmail compose message with the to, subject and body filled out. The main thing is that it works with craigslist. :)

For those looking for a simple solution, just drag this link onto your bookmark bar:
GMail Mailto

To use it, open a webpage with a mailto link on it and then click the bookmarklet. Now when you mouse-over a mailto link you will notice that it is now a javascript function instead. Clicking it will open up a GMail compose window.

For those interested in the code: javascript:( function() { /* Loop through all the links in the document. */ for (var i = 0; i < document.links.length; i++) { /* Get a pointer to this link for easy access. */ var link = document.links[i]; /* If this link is not a mailto link then skip it. */ if (link.href.indexOf('mailto') != 0) continue; /* Strip the 'mailto:' off the begining of the link. */ var strippedLink = link.href.slice(7); /* Convert the '?' after the e-mail address into an '&' so we can split the string on '&'. */ strippedLink = strippedLink.replace(/\?/, '&'); /* Split the link into an array of strings using the '&' as the delimiter to split on. */ var splitLink = strippedLink.split(/&/); /* The first item is always the to field. */ var to = splitLink[0]; /* Look for the other fields in the split link. */ var subject = ''; var body = ''; for (var j = 0; j < splitLink.length; j++) { var variable = splitLink[j]; /* Extract the subject, if this is a subject item. */ if (variable.match(/^subject=(.*)$/)) { subject = RegExp.$1; continue; } /* Extract the body, if this is a body item. */ if (variable.match(/^body=(.*)$/)) { body = RegExp.$1; continue; } } /* Create the address that will open our GMail compose message (with the to, subject and body fields filled in). */ gmailAddress = 'https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=' + to + '&su=' + escape(subject) + '&body=' + escape(body) + '&zx=RANDOMCRAP&shva=1&disablechatbrowsercheck=1&ui=1'; /* Alter the 'mailto:' link on the page to open a pop-up window to the gmailAddress. */ link.href = 'javascript:window.open(\'' + gmailAddress + '\', \'gmail_compose_popup_window\', \'left=((window.screenX||window.screenLeft)+10), top=((window.screenY||window.screenTop)+10), height=550px, width=650px, resizable=1, alwaysRaised=1\')'; } } )();

If anyone knows how GMail handles other fields like CC, BCC, etc. let me know and I'll add the code to the bookmarklet. I can make some educated guesses, but without a webpage to test against i don't want a broken script posted on this blog.
