Reusing code between different event handlers

Question

I have one code block which I want to invoke in different scenarios when a click is triggered, depending on whether the event is direct or is delegated.

But on changing

Answer 1

You don't have to use anonymous functions to handle events. Just write a regular function:

function handleClick(event) {
  // lots of code
}

Then bind the function to as many events as you want:

if (some condition) {
  $(document).on('click','.selected-option', handleClick);  
else {
  $('.selected-option').click(handleClick);
}
