Bind Same Event with Different Identifier in JavaScript

  Sometimes, you want to bind multiple function to an event in js. Accomplish that is simple, just repeatedly bind your functions to the event. Like the following,

$("#hatch-chick").bind("click", function(){ "remark the hatch date on the sheet.";});
$("#hatch-chick").bind("click", function(){ "turn on the heat lamp.";});

And you are able to remove the event functions by calling .unbind(eventName), like the following,

$("#hatch-chick").unbind("click");

  However, sometimes you do not want to remove all of them at once. You may want to remove the "remark" one specifically. To achieve that, you need to name your event by adding postfix to the origin event name. For example, click to click.remark. Adding the postfix would not affect the functionality, the function is still triggered by click event. But now, you are able to identify the function by naming click.remark, so you can unbind the "remark" function only.
  The following is a simple example.

$("#hatch-chick").bind("click.remark", function(){ "remark the hatch date";});
$("#hatch-chick").bind("click.heat", function(){ "turn on the heat lamp";});

$("#hatch-chick").unbind("click.remark");
