Instead of using ids #r, let's include in the element the attribute data-something to differentiate the elements that must have the behavior setted by the function. Using a div, for instance:

    <div data-something="1_1"></div>
    <div data-something="2_2"></div>

We won't need the ids with #r anymore. Considering that you already have the elements #h* we just need to put the id number inside data-something of the corresponding element, so that the function can use it:

    $("div[data-something]").hoverIntent(function() {
        var idNumber = $(this).data("something");
        $('#h' + idNumber).toggleClass('vis');
    });

Now, you just need to use the data-something attribute.
