Bootstrap Collapse - open the given id fragment

Answer 1

For really simple and quick to implement hash routing, you could try something like Routie

routie({
    accordionOne: function() {
        $('#accordionOne').collapse('show');
    },
    accordionTwo: function() {
        $('#accordionTwo').collapse('show');
    },
    accordionThree: function() {
        $('#accordionThree').collapse('show');
    }
});
