hm, thats a default in

UrlHelper::convert_options_to_javascript($html_options);

It's called because you set 'id=>...' as a html-option. You could provide a patch. ;-)

OK, the only thing I could do that seems to work is to modify UrlHelper::link_to. Is there no way to override built-in functions other than to modify the original? In any case, what I did was to I adda loop that checks for any javascript options. This may not be the best way to do this; if anyone knows of a better, more efficient method, I'm all ears:

function link_to($name = null, $options = array(), $html_options = array(), $parameters_for_method_reference = null)
{
if (!empty($html_options)) {

// foreach loop added by pw to make javascript an option, not a default

foreach (array('confirm', 'popup', 'post') as $option){
if (isset($html_options[$option])) {
$this->convert_options_to_javascript($html_options);
}
}
// end modification

$tag_options = TagHelper::_tag_options($html_options);
}
else{
$tag_options = null;
}
$url = is_string($options) ? $options : $this->url_for($options, $parameters_for_method_reference);
$name = empty($name) ? $url : $name;
return "<a href=\"{$url}\"{$tag_options}>{$name}</a>";
}
