Gravatar Javascript Multiple Emails

Question

Ref: Loading gravatar using jquery

I am using the above method to generate the gravatar on a page however I have multiple emails on the page and the code is only generating one MD5 and therefore only one gravatar my JS is:

var email = $('#email').val();
var digestString = Crypto.MD5(email);
$('#md5').val(digestString);
var gravatar = $('<img>').attr({src: 'http://www.gravatar.com/avatar/' + digestString});
$('.gravatar').append(gravatar);  

I am using Crypto MD5 http://code.google.com/p/crypto-js/ and that is loaded in the header the emails are held in a hidden input:

<input type="hidden" id="email" value="<?php echo $message['contact_email'];?>">

These are printing out ok for each user.

Any help would be great

EDIT *****

HTML OUTPUT Working:

<div class="message-author">
<span class="gravatar" style="height: 24px;">
      <img src="http://www.gravatar.com/avatar/82c9a9c254f35a912d8fefc248c30fd8"></span>
      <input type="hidden" id="md5" value="82c9a9c254f35a912d8fefc248c30fd8">
      <input type="hidden" class="email" value="themailname@thecompany.com">
</div>

HTML OUTPUT not Working:

<div class="message-author">
<span class="gravatar" style="height: 24px;">
      <img src="http://www.gravatar.com/avatar/82c9a9c254f35a912d8fefc248c30fd8"></span>
      <input type="hidden" id="md5" value="">
      <input type="hidden" class="email" value="themailname@thecompany.com">
</div>

PHP

<?php foreach ($messages['page'] as $message): ?>
    <li class="message">
        <div class="message-body"><?php echo $message['message']; ?></div>
        <div class="message-author">
            <span class="gravatar" style="height: 24px;"></span>
            <input type="hidden" class="md5" value="">
            <input type="hidden" class="email" value="<?php echo $message['contact_email'];?>">
            <?php echo $message['contact_person'];?> - 
            <?php echo date("m M - g:i a", $message['created']); ?>
        </div>
    </li>
<?php endforeach; ?>

Answer 1

Try the following:

$('input.email').each(function () {
    var self = $(this);
    var md5 = Crypto.MD5(this.value);

    self.siblings('.md5').val(md5);
    self.siblings('.gravatar').append($('<img />').prop('src', 'http://www.gravatar.com/avatar/' + md5));
});

You need to introduce a loop (via each() ) to consult each email element individually; otherwise, as you realised, only the first is looked at (as getters such as val() will only return the value of the first matched element.

However, as I hinted at in my comment , this should really be a job for PHP; it's also a potentially privacy issue sending users emails in your HTML.
