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))
    });
});

检测service worker:

navigator.serviceWorker.controller

删除service worker的代码:

navigator.serviceWorker.getRegistrations()
  .then(registrations => {
    registrations.forEach(registration => {
      registration.unregister();
    })
  });

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

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

  if ('caches' in window) {
      caches.keys()
        .then(function(keyList) {
            return Promise.all(keyList.map(function(key) {
                return caches.delete(key);
            }));
        })
  }

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

            setTimeout(function(){
              console.log('trying redirect do');
              window.location.replace(window.location.href); // because without redirecting, first time on page load: still service worker will be available
            }, 3000);
          }
        });
      }

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。

它也可以在Chrome通过应用程序选项卡:

打开此页面:chrome://serviceworker-internals，单击“取消注册”按钮。

如果你想注销所有的service worker，打开开发人员工具并在上面的页面上运行这段代码。

document.querySelectorAll("button.unregister").forEach(item=>{ item.click()})
