Syntax for getting "options" values from $.widget( "ns.plugin"

On the "Why Use the Widget Factory?" page, https://learn.jquery.com/jquery-ui/widget-factory/why-use-the-widget-factory/, the last example, what is the correct way to get the value of each "option"?

   $.widget( "ns.plugin", { 
       // Default options.
       options: {
           param1: "foo",
           param2: "bar",
           param3: "baz"
       },

       _create: function() {
           // Options are already merged and stored in this.options
           // Plugin logic goes here.
       } 
   });

Using this.options.param1 will get the correct value for this one entry, but a user should be able to get all of the values in options like an array.

Using the following code:

  $.each(this.options, function(key, value) {
     alert(key + ":" + value);
  });

returns:

• classes:[object Object]
• disabled:false
• create:null
• param1:foo
• param2:bar
• param3:baz

I expect the last 3 output, but not the first 3.

What is the proper syntax to just get:

• param1:foo
• param2:bar
• param3:baz

Open the “Why Use the Widget Factory?” page linked in the issue and review its final $.widget("ns.plugin") example. Determine how the example should distinguish the plugin's declared options from other option values, then update the page so the expected param1, param2, and param3 output and correct syntax are clear.
