Just installed it and it works perfectly, out of the box. Great!

Thank you very much for making a great snippet out of the emailobfuscation-script. grin

It actually took me longer to read the link at ALA that Sylvaticus supplied than it did to install this plugin!!

Seems to work great too. Doesn’t degrade nicely like the ALA one does, but hey, it’s pretty damn handy anyway!

[...] Thank you very much for making a great snippet out of the emailobfuscation-script.

Well, not exactly... Also, the ’<noscript>’ part is missing. Regarding graceful degradation (for those unlucky 6% without javascript), you could of cause insert a link to your contact form in the span element instead of notifying to turn javascript on: edit the plugin code and change

<span class=\"emo_address\">Turn on JavaScript!</span>

to

<span class=\"emo_address\"><a href=\"/url-of-your-contact-form.html\">contact me</a></span>

Have a look at this site if you want to do PHP’s auto_prepend_file outside a cms.

Really useful plugin, thanks floh.

One little observation:
it breaks eForms submitted with email field(s).

Quick fix:
wrap email address pattern search like this

if (!isset($_POST['submit'])) { //Eol: skip submitted pages
  $modx->documentOutput = preg_replace_callback("#<a[^>]*mailto:([^'\"]+)['\"][^>]*>([^<]*)</a>#i", "encodeLink", $modx->documentOutput);
  $modx->documentOutput = preg_replace_callback(email_regex(), "encodeLink", $modx->documentOutput);
}

Hi Folks

In IE7 I get an JS Error

Es ist ein Laufzeitfehler aufgetreten.

// addLoadEvent is Simon Willison's function that allows for convenient
// addition of multiple fuctions that are all supposed to be triggered
// on window.onload event.
// takes function name as the argument. e.g. addLoadEvent(doPopups);
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;  //*********** SCRIPT STOPS HERE

In FF 3.1 no probs.
Has anybody a clue what this could be?

Best regards
manu

EDIT:
Modification of plugin:

// Finish encrypted addresses block
$addressesjs .=
"      addLoadEvent(emo_replace);" . "\n" . //Parenthesis at emo_replace REMOVED
"    //-->" . "\n" . "    </script>" . "\n";

As you see, I removed the parenthesis in the plugin code and now it works in IE7 and FF3.0.
I’m no an JS pro. Could anybody confirm?
Thanks manu

As the function works nice with the modification mentioned above, nevertheless I put something on the wishlist:
The "turn java scipt on" tag is pretty ugly on slow clients, it flickers often when you refresh the page.
Did anybody think about to integrate the domready function of motools instead of window.onload?
In manager mode this plugin modification works IMHO:

// Finish encrypted addresses block
$addressesjs .=
"     window.addEvent('domready', function(){" . "\n" .
"        emo_replace();" . "\n" .
"      });" . "\n".
                                                                /*REPLACED "      addLoadEvent(emo_replace);" . "\n" .*/
"    //-->" . "\n" . "    </script>" . "\n";

Since motools is included in manager mode it should be possible to include it generally. But I don’t know how to fix this.

so long
