Javascript: Price Switching

gistfile1.js

// setup our default plans and their pricing options, we only support rounded to the dollar prices
var plans = {
	'standard': {
		price: 6,
		term: 10
	},
	'premium': {
		price: 10,
		term: 12
	},
	'delux': {
		price: 12,
		term: 15
	}
}


// insert these into the page. could hardcode into the page but this method
// allows for easier maintenance of the prices. we loop through all the plans,
// and using the names we insert them into the matching classes on the page.
$.each(plans, function(index, plan){
	$("."+index+".price").html(plan.price);
	$("."+index+".term").html(plan.term);
});


// if either of our radio options change run this
$('input[name=stories], input[name=bedrooms]').change(function() {

	// grab the current selected option's extra price data and convert to integer
	var a = $('input[name=stories]:checked').data("extra");
	var b = parseInt(a);
	var c = $('input[name=bedrooms]:checked').data("extra");
	var d = parseInt(c);

	// now for every plan type we have add the two options to the base prices
	// and then insert them into the page in the correct place as above.
	$.each(plans, function(index, plan){

		var price = plan.price + b + d;
		var term = plan.term + b + d;
		$("."+index+".price").html(price);
		$("."+index+".term").html(term);

	});
