Question

I have written some relatively simple jQuery plug-ins, but I am contemplating writing something more advanced in order to keep commonly used methods on the site easily accessible and DRY

For example, I might have something like this for a structure:

plugin
- popup
- element
...

=== popup ===
- login
- product
...

=== element ===
- shoppingCart
- loginStatus
...

So, to bind a popup login popup event, I’d like to be able to do:
$(‘#login_button’).plugin.popup.login();

What’s the best way to do this? Is there a better way of achieving what I want to do?

Cheers,

The way farhan Ahmad did it was pretty much right… it just needs deeper levels to suit your needs your implementation would look like this:

jQuery.fn.plugin = function(){
  //"community" (global to local methods) vars here.
  var selectedObjects = this; //-- save scope so you can use it later

  // return the objects so you can call them as necessary
  return {  
            popup: { //plugin.popup
                    login: function(){ //plugin.popup.login
                         //selectedObjects contains the original scope
                         console.log(selectedObjects);
                    },
                    product: function(){} //plugin.popup.product
            },
            element: { //plugin.element
                    shoppingCart: function() {}, //plugin.element.shoppingCart
                    loginStatus: function() {} //plugin.element.loginStatus
            }
         }
}

So now if you call:
$("#someDiv").plugin.login(); the result will be as expected. I hope this helps.
