外掛說明
WordPress 更新至 5.5 版後，便不再預設啟用移轉工具 jquery-migrate，這會造成某些執行舊版程式碼的佈景主題及外掛缺少功能或產生未預期的行為。
這個外掛提供一個暫時性的因應措施，它能為 WordPress 5.5 的網站啟用移轉指令碼，以便讓 (網站已採用的) 外掛及佈景主題開發者，能夠有更多時間完成程式碼更新及測試。
隨著 WordPress 5.6 的更新，內建的 jQuery 版本也一併升級。這代表以前觸發警告的舊版程式碼，現在會造成網站執行錯誤或全面停擺。
某些不再能正常執行的功能會在背景停止運作，而不會產生任何明顯的問題。
這個外掛能讓網站降級至舊版 jQuery 一段時間，但網站管理員仍應積極修復基礎問題。
安裝方式
- 將壓縮檔解壓縮後所得的
enable-jquery-migrate-helper資料夾及其檔案上傳至wp-content/plugins/資料夾。 - 請於 [外掛] 頁面啟用這個外掛。
- 大功告成！這個外掛會自動為網站處理接下來的工作。
常見問題集
-
『有些項目「已淘汰不用」』代表什麼？
-
當開發者使用更符合開發規範的指令碼、檔案或其他程式碼片段取代現有版本時，舊有項目便會遭到移除及棄用。
-
WordPress 5.6 發佈後的變更
-
隨著 WordPress 5.6 的發佈，內建的 jQuery 也一併完成了更新；這代表之前會出現「淘汰不用項目警告訊息」的外掛或佈景主題，現在會造成網站發生錯誤。這個外掛能讓網站在發生這類錯誤時，暫時性的改用舊版 jQuery 以修正程式碼或更換為其他程式，並且會在網站訪客讓網站產生第一次錯誤時就自動採取這項暫時性措施。
-
如何找到及使用瀏覽器主控台？
-
請參閱 WordPress.org 上的〈使用瀏覽器診斷 JavaScript 錯誤〉線上說明。
-
這個外掛不會記錄已遭淘汰不用的項目或變更 jQuery 版本
-
如果網站使用任何會合併 JavaScript 檔案，或以非同步方式載入 JavaScript 檔案，則這類外掛便會受到負面影響，導致無法如預期般執行。
如果網站需要這個外掛才能運作，請停用會以上述方式載入 JavaScript 檔案進行互動的外掛。當基礎問題解決後，網站管理員變可以移除這個外掛並重新啟用其他工具。
-
如何判斷網站是否需要這個外掛
-
如果 WordPress 網站升級後發生異常狀況，網站管理員便可以為網站安裝並啟用這個外掛。如果安裝啟用這個外掛後異常狀況有了緩解，請保持這個外掛的啟用狀態，並遵循外掛顯示的相關說明。當網站不再需要這個外掛時，外掛會顯示相關提示。
-
使用 jQuery v3 時，出現很多「淘汰不用項目警告訊息」
-
對 WordPress 來說，jQuery v3 是非常新的版本，因此這些都是可預期的狀況。
「淘汰不用項目通知」代表移轉工具已準備就緒，它能確保相關程式碼在第三方開發者進行更新、修改的期間，相關功能仍能正常執行。

I really do think that you should still include or incorporate jquery migrate files in new versions or updates of wordpress. It’s crazy that you know this is gonna crash a bunch of sites (like thousands) yet you do it anyway. Oh, and while I’m here, please get rid of the block editor (or whatever the hell it is) in these comments! It’s not intuitive enough. Poor UX/UI. 😟☹️

Congratulations to whoever made this plugin. There were some editor display issues on wordpress and the plugin fixed them. Now clearly I have to go back to the problem to restore the correct functioning of wordpress. but wow! it was amazing!

This is an excellent plugin! Works perfectly!
I just wish there was an option to turn off the message that says this is not a permanent fix.

Boy did this come in handy. Thanks for doing this. It got the menus working. This will give us time to replace the existing theme with our own.
Thanks again!

I was tired of seeing the jQuery red error, so I made a site backup and installed the plugin thinking I would need to do some sort of tweaking. However, I looked immediately after the install and no error whatsoever. I was pleasantly surprised. 5 Stars for sure. Thanks.
