过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

hardwareUnitId 只读特性在 VRDevice interface returns the distinct hardware ID for the overall hardware unit that this VRDevice is a part of. All devices that are part of the same physical piece of hardware will have the same hardwareUnitId .

句法

var hardwareID = VRDevice.hardwareUnitId;
					

值

A DOMString containing the ID of the overall hardware unit.

范例

The following snippet (see our VRDevice example ) returns an array of all the VRDevice s connected to your computer via Navigator.getVRDevices() . For each connected device it then prints out the hardwareUnitId , VRDevice.deviceId ，和 VRDevice.deviceName .

var list = document.querySelector('ul');
var info = document.querySelector('p');
if(navigator.getVRDevices) {
  navigator.getVRDevices().then(function(myDevices) {
    reportDevices(myDevices);
  });
} else {
  info.textContent = 'WebVR API not supported by this browser.'
}
function reportDevices(devices) {
  for(i = 0; i < devices.length; i++) {
    var listItem = document.createElement('li');
    listItem.innerHTML = 'Device ' + (i+1)
                 + ': <strong>Hardware ID</strong>: ' + devices[i].hardwareUnitId
                 + ', <strong>VD Device ID</strong>: ' + devices[i].deviceId
                 + ', <strong>VR Device Name</strong>: ' + devices[i].deviceName
                 + '.';
    list.appendChild(listItem);
  }
}
