Add jQuery function to specific elements

Question

I know that you can add new jQuery functions by $.fn.someFunction = function()

However, I want to add functions to specific elements only. I tried this

Answer 1

The most obvious solution is to assign a function as the object's property:

obj.prop("myFunc", function() {
  return (function(arg) {
    alert("It works! " + arg);
  });
});

Then call it on the object this way:

obj.prop("myFunc")("Cool!");

Note: your function is the return value of the outer one, see: http://api.jquery.com/prop/#prop-propertyName-function
