.click() expects a function as the argument, you where passing $("#myFlippyBox").click({...});
instead of $("#myFlippyBox").click(function(){...});
Try
$(document).ready(function() {
$("#myFlippyBox").click(function() {
$(this).flippy({
content : "Hi !",
direction : "TOP",
duration : "750",
onStart : function() {
alert("Let's flip");
},
onFinish : function() {
alert("ok, it's flipped :)");
}
});
});
});
