iframeRPC

RPC style messaging for cross domain iframes in the browser. Relies on window.postMessage (backwards compat to ie8)

IMPORTANT this library uses JSON.stringify for data serialization between frames, this is to support ie8 which doesn't support "structured clone algorithm" serialization through window.postMessage, and only allows for passing strings.

Services Example:

var services = {
	'getPrice': function(input, done) {
		return done(null, 143.29);
	},
	'sum': function (nums, done) {
		return done(null, nums.reduce(function (acc, cur) {
			return acc + cur;
		}));
	}
};

iframeRPC.createService(services, '[CHILD DOMAIN]', window.frames.mtoc);

Client Example:

var client = iframeRPC.createClient('[PARENT DOMAIN]');
client('getPrice', 1234, function (err, price) {
	alert('price:' + price);
});
client('sum', [1,2,3,4], function (err, total) {
	alert('total:' + total);
});
