What is messaging? Summary of examples about message communication

HTML5 supports cross-document messaging (Cross-Document Messaging). Since message communication is used, events must occur. According to the generation and consumption of events, we can find the sender and receiver, that is, Sender and Listener. Litener needs to do the following work: write a message processing function; register the message processing function: addEventListener('message', function, false); where Sender needs to do the following work: postMessage('this is a message', 'http: //m.sbmmt.com'); The members included in the event object event include: data: passed data; origin: origin, origin includes three elements: host, protocol, port; source: source object; OK, let’s Take a look at an example that shows nesting pages within pages and sending messages to subpages
