The isConnected read-only property of the VRDisplay interface returns a Boolean indicating whether the VRDisplay is connected to the computer.

Syntax

var isItConnected = vrDisplayInstance.isConnected;

Value

A Boolean; true means the display is connected; false means it isn't.

Examples

navigator.getVRDisplays().then(function(displays) {
  // If a display is available, use it to present the scene
  if(displays.length > 0) {
    vrDisplay = displays[0];

    // Starting the presentation when the button is clicked: It can only be called in response to a user gesture
    btn.addEventListener('click', function() {
      // Only request presentation if the display is still connected.
      if(vrDisplay.isConnected) {
        vrDisplay.requestPresent([{ source: canvas }]).then(function() {
          // start rendering the app, etc.
        });
      } else {
        console.log('Connection to display lost');
      }
    });
  }
