```
+ var pk_ignore_regexp = ‘(?:^| )(piwik_ignore’;
+ for( var i=0; i < piwik_ignoreclasses.length; i++)
+ pk_ignore_regexp += ‘|’ + piwik_ignoreclasses[i];
+ _pk_ignore_regexp = ‘)(?: |$)’;
+
+ var pk_class = new RegExp(_pk_ignoreregexp);
+
if (document.getElementsByTagName) {
linksElements = document.getElementsByTagName(‘a’)
for (var i = 0; i < linksElements.length; i+) {
- if( linksElements[i].className != ‘piwik_ignore’ )
- _pk_add_event(linksElements[i], ‘mousedown’, pk_click, false);
+ if( !_pkclass.exec( linksElements[i].className ) )
+ _pk_add_event(linksElements[i], ‘mousedown’, _pk_click, false);
}

Disable the download & outlink tracking for specific CSS classes

You can disable automatic download and outlink tracking for links with specific CSS classes:

[…]
piwik_url = http://yourwebsite/piwik/piwik.php;
// do not track links <a href= class=no-tracking>
piwik_ignore_classes = [“no-tracking”];
piwik_log(piwik_action_name, piwik_idsite, piwik_url);
[…]
