我有一個JavaScript文件，我創建它的工作如下： - 它將驗證在我的html表單的字段中輸入的名稱和電子郵件。如果電子郵件或名稱無效，則JavaScript會向用戶發出警報，並警告他所輸入的電子郵件或名稱無效。在JavaScript中刪除onBlur標記？
無論如何，此警報將POP操作向上「的onblur」。（當光標退出名字和電子郵件領域）
我想刪除「的onblur」的標籤。我希望驗證在填表完成時發生，當用戶單擊「提交」時。
如何做到這一點？用哪個標籤我必須替換「onBlur」？ 順便說一句我嘗試用「onClick」替換「onBlur」：當我點擊該字段填充它時，警報出現。
這是JavaScript在我的HTML放置在頭部和/ head標籤之間**
