chrome啟用插件

When you visit a webpage in a browser, all the resources, such as images, style sheets, and Javascript files, are downloaded and stored in the browser’s cache. This allows webpages you’ve already visited to load more quickly because the browser doesn’t have to download the resources again.

當您在瀏覽器中訪問網頁時，所有資源(例如圖像，樣式表和Javascript文件)都會下載并存儲在瀏覽器的緩存中 。 這樣一來，您已經訪問過的網頁就可以更快地加載，因為瀏覽器無需再次下載資源。

Update: Google removed this experimental flag from Chrome. If you try to visit a web page while you’re offline, Chrome may automatically load cached versions of some web pages—but there’s no way to control this. Mozilla Firefox still has a built-in “Work Offline” mode, so you may want to try Firefox.

更新 ：Google從Chrome刪除了此實驗性標志。 如果您嘗試在離線狀態下訪問網頁，Chrome可能會自動加載某些網頁的緩存版本，但無法對其進行控制。 Mozilla Firefox仍然具有內置的“脫機工作”模式 ，因此您可能需要嘗試Firefox。

The cache can also be useful if you know you’re going to be somewhere where the internet connectivity is spotty, or where you won’t have any connection at all. Chrome’s offline mode allows you to use the cache to view webpages you’ve already visited (and were copied to the cache) when you are offline.

如果您知道將要出現互聯網連接不暢或根本沒有任何連接的地方，則緩存也很有用。 Chrome的離線模式可讓您在離線狀態下使用緩存來查看已經訪問過(并已復制到緩存中)的網頁。

Chrome’s built-in offline mode is not easy to find, but we’ll show you where to find it and how to enable and use it.

Chrome的內置脫機模式不容易找到，但我們將向您展示如何找到它以及如何啟用和使用它。

NOTE: Offline mode is enabled in the chrome://flags features. These are experimental features that may change, break, or disappear at any time and could negatively affect your browsing experience. However, if you follow our instructions, you should have no problem.

注意：在chrome：// flags功能中啟用了離線模式。 這些實驗性功能可能隨時更改，中斷或消失，可能會對您的瀏覽體驗造成負面影響。 但是，如果您遵循我們的指示，則應該沒有問題。

To enable the built-in offline mode in Chrome, type chrome://flags/#show-saved-copy ?in the address bar and press “Enter”.?This will take you directly to the command you’ll be enabling, which makes toggling the setting even easier.

要在Chrome中啟用內置的離線模式，請在地址欄中輸入chrome://flags/#show-saved-copy ，然后按“ Enter”。 這將直接帶您將要啟用的命令，這使切換設置更加容易。

Under “Show Saved Copy Button”, select “Enable: Primary” from the dropdown list. The “Enable: Secondary” option provides the same functionality in a slightly different way. You can use either and we’ll discuss the difference a bit later in this article.

在“顯示保存的副本按鈕”下，從下拉列表中選擇“啟用：主要”。 “啟用：輔助”選項以略有不同的方式提供相同的功能。 您可以使用其中任何一個，我們將在本文稍后討論差異。

To have your change take effect, click “Relaunch Now”.

要使更改生效，請單擊“立即重新啟動”。

Now, when you’re offline and you visit a website, it will be loaded entirely from the saved copy in the cache instead of downloaded from the website’s server. So, if you know you’re going to be without an internet connection, be sure to visit the websites you want offline access to before then, so they are stored in the cache for offline access.

現在，當您離線并訪問網站時，它將完全從緩存中的已保存副本加載，而不是從網站的服務器下載。 因此，如果您知道將要沒有Internet連接，請確保在此之前訪問要脫機訪問的網站，以便將它們存儲在緩存中以供脫機訪問。

When you visit a website while you’re offline, you may briefly see the following “This site can’t be reached” screen. This screen displays when “Enable: Primary” is selected in the Show Saved Copy Button drop-down list on the chrome://flags page. Notice that the “Show saved copy” button is blue and is displayed to the left of the Reload button.

當您離線訪問某個網站時，您可能會短暫看到以下“無法訪問此網站”屏幕。 在chrome：// flags頁面的“顯示已保存的副本按鈕”下拉列表中選擇“啟用：主要”時，將顯示此屏幕。 請注意，“顯示保存的副本”按鈕為藍色，并顯示在“重新加載”按鈕的左側。

This screen goes away quickly, but there will be another one (we’ll show you in a bit) that will allow you to access the cached copy of the website you’re trying to visit.

該屏幕很快消失，但是將出現另一個屏幕(稍后將向您展示)，該屏幕使您可以訪問要訪問的網站的緩存副本。

If you selected “Enabled: Secondary” under Show Saved Copy Button, the “Show saved copy” button is gray and on the right. But, it works the same way in either position.

如果在“顯示已保存的副本”按鈕下選擇了“已啟用：輔助”，則“顯示已保存的副本”按鈕為灰色，位于右側。 但是，無論在哪個位置，其工作方式都相同。

The “This site can’t be reached” screen is replaced with the “There is no Internet connection” screen. To access the cached version of the website you’re trying to visit, click the “Show saved copy” button.

“無法訪問此站點”屏幕將替換為“沒有互聯網連接”屏幕。 要訪問您要訪問的網站的緩存版本，請單擊“顯示保存的副本”按鈕。

In addition to Chrome for Windows, the offline mode feature is also available in Chrome for Mac, Linux, Chrome OS, and Android, and works the same way as it does in Windows.

除了適用于Windows的Chrome，脫機模式功能還適用于Mac，Linux，Chrome OS和Android的Chrome，其工作方式與Windows相同。

Remember that you are viewing old versions of webpages when you access cached copies of them. You can use offline mode to view any website offline, but it’s probably more useful for websites that don’t update that often, so the cached copy is not quite so out-of-date. Besides viewing cached copies of websites while you’re offline, there are also many Chrome apps that you can use offline.

請記住，當您訪問網頁的緩存副本時，您正在查看的是舊版本。 您可以使用脫機模式來脫機查看任何網站，但是對于不經常更新的網站來說，它可能更有用，因此緩存的副本并不是太過時了。 除了在離線狀態下查看網站的緩存副本之外，還有許多Chrome應用程序可以離線使用 。

If you visit a website that is not cached, you’ll see the screen above, but the Show saved copy button will not be available. Also, if you clear your cache, you’ll have to visit the websites you want offline access to while you have an internet connection, so those websites are stored in your cache again and available when you do not have an internet connection. Not clearing your cache is also a way to speed up your browsing experience in Chrome.

如果您訪問未緩存的網站，則會看到上面的屏幕，但“顯示保存的副本”按鈕將不可用。 另外，如果您清除緩存 ，則必須在具有Internet連接時訪問要脫機訪問的網站，以便這些網站再次存儲在緩存中，并且在沒有Internet連接時可用。 不清除緩存也是加快Chrome瀏覽體驗的一種方法。
