I've been working with the RaphaelJS 'australia map' example that displays text in a DIV when a state is clicked on. However I'm having difficulty working with it to create different events and functions.

I want to be able to duplicate the 'display text' function for two different element onClick events (i.e. have two different buttons (elements) that do the same thing). But the current code is a bit too complicated for me. Can somebody please help me simplify the code that displays the text in a DIV when an element is clicked on.

Any help would be much appreciated - this is what I'm currently working with jsfiddle.

 window.onload = function () {
    var R = Raphael("paper", 532, 500);
    var attr = {
        fill: "#0B0",
        stroke: "#fff",
        "stroke-width": 3,
    };
    var ctx = {};
    ctx.btn_1 = R.path("M 180,130 L 340,130, L 392,212, L 128,212 z").attr(attr);
    ctx.btn_2 = R.path("M 128,212 L 392,212, L 435,280, L 85,280 z").attr(attr);
        
    var current = null;
    for (var state in ctx) {
        (function (st, state) {
            st[0].style.cursor = "pointer";
            st[0].onmousedown = function () {
                current && (document.getElementById(current).style.display = "");
                st.toFront();
                R.safari();
                document.getElementById(state).style.display = "block";
                current = state;
            };
        })(ctx[state], state);
    }
 };

};
