I have a number of table rows that I would like to toggle the visibility of. They should be visible if a data item I have set on them earlier equals a selected value in a form. This is what I have so far:

$('#category-selector').change(function(event)
{
    var category_id = $(this).val();

    if(!category_id)
    {
        $('tr', '#table tbody').show();
    }
    else
    {
        $('tr', '#table tbody').toggle();
    }
});

Of course this just toggles them on and off. Thing is that I thought I was able to give toggle a function that would decide if each row should be on or off, but it turns out I can only give it a boolean condition which would be an all or nothing deal kind of...

So, I have this function:

function()
{
    return $(this).data('category_id') == category_id;
}

How can I use that to go through all the rows and toggle them on or off? Or is there a better approach to this? What should I do?
