對不起，這個問題看起來像是重複的，我已經看過幾個關於通過表單發送電子郵件，但仍然無法使其發揮作用的問題。如何使用發送表格發送表單中的電子郵件
相關情況下的背景信息：網站位於Azure上，電子郵件服務爲sendgrid。我下載了zip文件http://swiftmailer.org/download，並將其包含在我的項目中。
目標：讓用戶填寫2個字段，接收包含該內容和預設主題行的電子郵件。
問題/問題：未發送電子郵件。另外，提交時，表單按預期消失，但沒有任何迴應，並且加載了js的頁面部分從頁面中消失。
顯示的控制檯錯誤是：「意外」或文件結束，所有打開的元素應在文檔結束之前關閉。 （指向表單開始前的行）。我不完全理解爲什麼這是一個錯誤，因爲我的body元素在關閉html之前是關閉的。
我現在可以忍受js問題，但如果有人能幫助我理解爲什麼沒有發送電子郵件/沒有任何迴應，將不勝感激。
在此先感謝！
