Multiple JS event handlers on single element

Question

I am working with an existing web app, in the app there are a variety of submit buttons on different forms, some using regular http post, some defining an onClick function,

Answer 1

jQuery makes this easy.

$(document).on('click', '.someclass', function() {
  doStuff();
});

$(document).on('click', '.someclass', function() {
  doMoreStuff();
});

Handlers then both will fire on click. jQuery keeps a queue of handers for you. And handles document clicks that match a selector of your choice so that they can be triggered no matter when your buttons are created.
