This code doesn't actually work; it's just aspirational. | |||
Assume that the following code is contained in a file at <tt>chrome://some_extension/content/foo.html</tt>. | |||
<pre> | |||
<html> | |||
<!-- This script makes the SecurableModule global available. --> | |||
<script src="securable-module.js"></script> | |||
<script> | |||
// Create a loader for SecurableModules that gives them chrome | |||
// privileges by default and roots the filesystem at (our URL)/lib. | |||
var loader = SecurableModule.Loader({defaultPrincipal: "system", | |||
rootPath: "lib"}); | |||
// Load the 'foo' SecurableModule and call its exported doSomething() | |||
// function. | |||
loader.require('blarg').doSomething(); | |||
window.addEventListener( | |||
"unload", | |||
function() { | |||
// Send an unload signal to free any resources created by modules so | |||
// far. | |||
loader.require('unload').send(); | |||
}, | |||
false | |||
); | |||
</script> | |||
</html> | |||
</pre> | |||
Note that the <tt>unload</tt> module conventions are laid out by the [http://narwhaljs.org/narwhal.html Narwhal] CommonJS-based platform. | |||
