此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。
Permissions API的Permissions接口提供核心PermissionAPI功能，例如查询和撤消权限的方法。
方法
Permissions.query()- 返回给定API的用户权限状态。
Permissions.request()-
请求使用给定API的权限，目前此功能尚未在任何浏览器中被支持。
Permissions.requestAll()- 请求使用一组给定API的权限。目前此功能尚未在任何浏览器中被支持。
Permissions.revoke()- 返回撤消当前在给定API上设置的权限。
Example
navigator.permissions.query({name:'geolocation'}).then(function(result) {
if (result.state === 'granted') {
showLocalNewsWithGeolocation();
} else if (result.state === 'prompt') {
showButtonToEnableLocalNews();
}
// 如果没有此权限则不什么也做
});
