RuleOptions.excludeDomains

By Opera Software

From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.

Description:

An array of zero or more domains on which to not apply a given URL Filter rule.

This property is passed within a RuleOptions object as a parameter for URL Filter methods.

Syntax:

DOMString[] excludeDomains

Example:

The following example blocks any content from facebook.com, but only when accessed from the cnn.com domain, e.g. a "Like" or "Recommend" button.

<!--
  The configuration file ('config.xml').
-->
<?xml version='1.0' encoding='utf-8'?>
<widget xmlns="http://www.w3.org/ns/widgets">
    ...
    <feature name="opera:urlfilter"/>
</widget>

//
// The background process (e.g. index.html)
//

// Check that the URL Filter API exists
if (typeof opera.extension.urlfilter != 'undefined') {
  // Set the options for the filter rule
  var ruleOptions = {
    excludeDomains: ['cnn.com']
  }

  // Assign the URLFilter object to a variable for efficiency
  var filter = opera.extension.urlfilter;

  filter.allow.add('||facebook.com/*', ruleOptions);
  filter.block.add('||facebook.com/*');
}

Note the use of || which is a hostname mark. This indicates that the subsequent characters should begin matching from any host name in the URL. For example, ||example.com* matches http://example.com/, https://www.example.com/, or similar. However, it will not match http://badexample.com/.
