Using the Gamepad API - Web APIs
ll automatically be visible. you can use gamepadconnected like this: window.addeventlistener("gamepadconnected", function(e) { console.log("gamepad connected at index %d: %s. %d buttons, %d axes.", e.gamepad.index, e.gamepad.id, e.gamepad.buttons.length, e.gamepad.axes.length); }); each gamepad has a unique id associated with it, which is available on the event's gamepad property. disconnecting a gamepad when a gamepad is disconnected, and if a page has previously received data for that gamepad (e.g. gamepadconnected), a second event is dispatched to the focused window, gamepaddisconnected: window.addeventlistener("gamepaddisconnected", function(e) { console.log("gamepad disconnected from index %d: %s", e.gamepad.index, e.gamepad.id); }); the gamepad's index property will be un...
...ing the usb vendor and product id of the controller, and the name of the controller as provided by the driver. this information is intended to allow you to find a mapping for the controls on the device as well as display useful feedback to the user. index: an integer that is unique for each gamepad currently connected to the system. this can be used to distinguish multiple controllers. note that disconnecting a device and then connecting a new device may reuse the previous index. mapping: a string indicating whether the browser has remapped the controls on the device to a known layout. currently there is only one supported known layout — the standard gamepad. if the browser is able to map controls on the device to that layout the mapping property will be set to the string standard. connected: a bo...

MutationObserver.takeRecords() - Web APIs

...n value an array mutationrecord objects, each describing one change applied to the observed portion of the document's dom tree. note: the queue of mutations which have occurred, but not been delivered to the observer's callback is left empty after calling takerecords(). example in this example, we demonstrate how to handle any undelivered mutationrecords by calling takerecords() just before disconnecting the observer. const targetnode = document.queryselector("#someelement"); const observeroptions = { childlist: true, attributes: true } const observer = new mutationobserver(callback); observer.observe(targetnode, observeroptions); /* ...later, when it's time to stop observing... */ /* handle any still-pending mutations */ let mutations = observer.takerecords(); observer.disconnect(); i...

Broadcast Channel API - Web APIs
is up to the code to know what kind of messages to expect and what to do with them. receiving a message when a message is posted, a message event is dispatched to each broadcastchannel object connected to this channel. a function can be run for this event with the onmessage event handler: // a handler that only logs the event to the console: bc.onmessage = function (ev) { console.log(ev); } disconnecting a channel to leave a channel, call the close() method on the object. this disconnects the object from the underlying channel, allowing garbage collection. // disconnect the channel bc.close(); conclusion the broadcast channel api's self-contained interface allows cross-context communication. it can be used to detect user actions in other tabs within a same origin, like when the user logs in ...

RTCPeerConnection: connectionstatechange event - Web APIs
ectivity of the webrtc session. it simply calls an app-defined function called setonlinestatus() to update a status display. pc.onconnectionstatechange = ev => { switch(pc.connectionstate) { case "new": case "checking": setonlinestatus("connecting..."); break; case "connected": setonlinestatus("online"); break; case "disconnected": setonlinestatus("disconnecting..."); break; case "closed": setonlinestatus("offline"); break; case "failed": setonlinestatus("error"); break; default: setonlinestatus("unknown"); break; } } you can also create a handler for connectionstatechange by using addeventlistener(): pc.addeventlistener("connectionstatechange", ev => { switch(pc.connectionstate) { /* ... *...

A simple RTCDataChannel sample - Web APIs
; receivebox.appendchild(el); } this method simply performs some basic dom injection; it creates a new <p> (paragraph) element, then creates a new text node containing the message text, which is received in the event's data property. this text node is appended as a child of the new element, which is then inserted into the receivebox block, thereby causing it to draw in the browser window. disconnecting the peers when the user clicks the "disconnect" button, the disconnectpeers() method previously set as that button's handler is called. function disconnectpeers() { // close the rtcdatachannels if they're open. sendchannel.close(); receivechannel.close(); // close the rtcpeerconnections localconnection.close(); remoteconnection.close(); sendchannel = null; ...
