jQuery：重构为函数

Question

I'm messing about with JavaScript/jQuery, and just trying to determine how to refactor two very similar:

 $('#a-div-element').click(function() {
    /* common stuff in here */
})

into one function with two arguments. I'd expected it to be somewhat similar to other languages I've used, that is:

function my_refactored_stuff(field, target_div) {
  $(field).click(function{ 
    /* common stuff in here */
  });
}

But that doesn't seem to trigger when clicked

In short, if someone could do up a quick example of how to write up a function that handles common functionality across .click methods, I'd be really appreciative

Many thanks, PlankTon

Answer 1

Just define and re-use an event handler function.

var handler = function(event) { /* common stuff here */ }
$("#a-div-element").on("click", handler)
$("#b-div-element").on("click", handler)

Answer 2

var callback = function() {};

$('#a-div-element').click( callback );

Or if you wish to pass arguments:

$('#a-div-element').click(function() {
    callback( /* args */ );
});
