Im trying to convert my jQuery script to a Prototype compatible one, but i cant seem to get it to work. Can someone please help me? Basically what it does is allow you to click an entire html table row to check/uncheck a checkbox.

$('input:checkbox').hide()
$('.clickable tr').click(function() {
var $checkbox = $(this).find(':checkbox').filter(':first');
$checkbox.attr('checked', !$checkbox.attr('checked'));
$(this).toggleClass('selected');
});

In Prototype you use $$() to select elements with css-like selectors.

This returns an Array of Elements. Then you could use the .each() method on the returned value:

$$('input:checkbox').each(function(e) { e.hide(); });

For events, you use the Element.observe() method:

$$('.clickable tr').each(function(e) {
    e.observe(function(event) {
        var checkbox = $(this).select('[type="checkbox"]:first');
        checkbox.checked = !checkbox.checked;
        $(this).addClassName('selected');
    });
});
