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。

PermissionStatus 接口在权限 API provides the state of an object and an event handler for monitoring changes to said state.

特性

PermissionStatus.state 只读: Returns the state of a requested permission; one of 'granted' , 'denied' ，或 'prompt' .
PermissionStatus.status 只读: Returns the state of a requested permission; one of 'granted' , 'denied' ，或 'prompt' . Later versions of the specification replace this with PermissionStatus.state .

Event Handler

PermissionStatus.onchange: An event called whenever PermissionStatus.status 改变。

范例

navigator.permissions.query({name:'geolocation'}).then(function(permissionStatus) {
  console.log('geolocation permission status is ', permissionStatus.state);
  permissionStatus.onchange = function() {
    console.log('geolocation permission status has changed to ', this.state);
  };
});
