Jquery function on attribute change

Question

I want to do some function when an attribute of a class changes. I wrote following JQuery:

var dropdown = $(".megadropdown").attr("style");

$(dropdown).change(function() {
  alert("hi");
});

So i want to do alert something whne the attriubute style changes. It is not working. Any suggestions?

Answer 1

Instead of just alert. Try:

$(dropdown).change(function() {
window.alert("hi");
});

I had this problem for some reason it worked for me.
