Loading gravatar using jquery

Just trying to crate a simple comment form on a blog. I want to load the user's gravatar (using jquery) when he/she writes this in the email box.

Anybody have a good code-snipit?

Answer Source

The gravatar url looks like this:


Here are the rest of the options for the URL.

So all you're going to have to do is include a function called md5 that returns the md5 hash of the user's email. There are many online that do this, but I believe this one works well. After that, just do:

// get the email
var email = $('#email').val();
// -- maybe validate the email? 

// create a new image with the src pointing to the user's gravatar
var gravatar = $('<img>').attr({src: 'http://www.gravatar.com/avatar/' + md5(email)});
// append this new image to some div, or whatever

// OR, simply modify the source of an image already on the page
$('#image').attr('src', 'http://www.gravatar.com/avatar/' + md5(email));

I thought this was obvious, but I will add it for posterity's sake:

If user emails are private and you're showing this ala-stackoverflow in a listing, you are probably better off encoding the email on the server so that user emails are not publicly visible if you look at the source.
