AJAX在phpMyAdmin中啟用後，能通過(guò)異步加載實(shí)現(xiàn)界面動(dòng)態(tài)更新，減少頁(yè)面整體刷新。具體作用包括：1. 瀏覽大表時(shí)通過(guò)AJAX加載新行，無(wú)需重載整個(gè)頁(yè)面；2. 查詢(xún)結(jié)果可即時(shí)顯示在SQL輸入框下方；3. 部分對(duì)話(huà)框（如重命名、刪除）以浮動(dòng)層形式打開(kāi)。若禁用AJAX，則這些操作會(huì)回退到傳統(tǒng)頁(yè)面加載方式，影響用戶(hù)體驗(yàn)。通常建議保持啟用以提升交互流暢度，僅在遇到JavaScript錯(cuò)誤或使用老舊瀏覽器時(shí)考慮禁用。設(shè)置路徑為：phpMyAdmin → 設(shè)置（齒輪圖標(biāo)）→ 主頁(yè)簽→ 啟用AJAX，該配置為用戶(hù)獨(dú)立保存，不影響其他用戶(hù)。

When you enable the "Enable AJAX" setting in phpMyAdmin, it allows certain actions and interface elements to work more dynamically without reloading the whole page. This makes interactions feel smoother and faster.

What does AJAX do in phpMyAdmin?

AJAX stands for Asynchronous JavaScript and XML. In the context of phpMyAdmin, enabling AJAX means that parts of the interface can update on the fly—like loading table data, running queries, or navigating between sections—without needing to refresh the entire browser window.

For example:

• When browsing a large table, pagination might load new rows via AJAX instead of reloading the full page.
• Query results may appear instantly below your SQL input without leaving the SQL tab.
• Some dialog boxes (like rename, drop, or export) might open as overlays rather than separate pages.

If AJAX is disabled, these actions will fall back to traditional page loads, which can be slower and less responsive from a user experience standpoint.

Should you keep AJAX enabled?

In most cases, yes , you should leave AJAX enabled. It improves usability and responsiveness, especially when working with larger databases or performing frequent operations.

However, there are some situations where disabling AJAX might help:

• If you're experiencing JavaScript errors or interface glitches in phpMyAdmin
• On very old browsers that don't support modern JavaScript features
• When debugging issues related to dynamic content loading

It's not a performance booster in terms of query speed—it only affects how the UI behaves.

Where do you find this setting?

You can toggle the AJAX option under: phpMyAdmin → Settings (gear icon) → Main tab → Enable AJAX

This preference is saved per-user if phpMyAdmin is configured to store settings (usually in the phpmyadmin database). So changing it won't affect other users on the same server.

Keep in mind that even with AJAX enabled, not all features behave the same across versions. Older versions of phpMyAdmin might use AJAX less extensively than newer ones.

基本上就這些。
