典型的JavaScript循环与所有东西兼容:

navigator.serviceWorker.getRegistrations().then(function(registrations) {
    var registrationslength = registrations.length;
    for (var i = 0; i < registrationslength; i++) {
        registrations[i].unregister();
    }
})

如果你的服务人员不让你更新文件。你需要用下面的代码替换serviceworker文件(sw.js / serviceworker .js):

self.addEventListener('install', function(e) {
  self.skipWaiting();
});

self.addEventListener('activate', function(e) {
  self.registration.unregister()
    .then(function() {
      return self.clients.matchAll();
    })
    .then(function(clients) {
      clients.forEach(client => client.navigate(client.url))
    });
});

典型的JavaScript循环与所有东西兼容:

navigator.serviceWorker.getRegistrations().then(function(registrations) {
    var registrationslength = registrations.length;
    for (var i = 0; i < registrationslength; i++) {
        registrations[i].unregister();
    }
})

以编程方式删除Service worker:

你可以像这样通过编程方式删除service worker:

navigator.serviceWorker.getRegistrations().then(function(registrations) {
    for(let registration of registrations) {
        registration.unregister();
    } 
});

文档:getRegistrations, unregister

通过用户界面移除Service worker

你也可以在Chrome Devtools的Application标签下删除service worker。

您应该在设备中检测到两个API: getRegistrations和getregiregistration。service-worker并不是在所有平台上都有一组唯一的api。例如，一些浏览器只有navigator.serviceWorker。getregiregistration，没有navigator.serviceWorker.getRegistrations。所以你应该两者都考虑。

安全卸载Service Worker

if ('serviceWorker' in navigator) {
      navigator.serviceWorker.getRegistrations().then(function (registrations) {
        for (const registration of registrations) {
          // unregister service worker
          console.log('serviceWorker unregistered');
          registration.unregister();
        }
      });
    }
