現在，我有一個HTML表單，代碼如下所示。它有一個按鈕，在每次用戶更改信息時，該按鈕將打開一個新選項卡（URL）並更新PHP頁面上的信息。現在，PHP頁面顯示在另一臺設備上，並且包含更新的信息，因爲我使用.txt並將其放在同一臺服務器上。現在的問題是更新後的信息僅在頁面刷新結束時顯示，這是不是我想要的你可以把刷新和更新js腳本在相同的功能？
我的問題是，現在，我的js函數充盈和更新變量我也包括在它的刷新功能以及
目標：？按鈕更新，並刷新在同一時間的URL（PHP頁面），以便最終用戶不必刷新它在他們的一端，刷新在同一臺服務器上的URL。
我嘗試使用loc到那裏，但它似乎沒有正在工作。

它不會更新服務器上的內容。它只會更新當前機器上打開的url。我需要它在相同的服務器上更新相同的URL，以便我的其他設備打開PHP網址也會更新。 –
