這是jQuery表單驗證（html，css和jQuery），但代碼不工作，所有if語句和錯誤消息我無法修復。表單驗證在jQuery中不起作用
$("#validationForm").submit(function(event) {
var errorMessage = "";
event.preventDefault();
function
isValidEmailAddress(emailAddress) {
var pattern = new RegExp(/^((([a-z]|\d|

你可以從你想要達到的目標開始，然後解釋代碼做了什麼或者沒有做什麼。你也可以解釋你已經試過調試它。否則沒有人會非常傾向於挖掘這個怪異的正則表達式。如果這確實是你想要做的事情，那麼在那裏驗證電子郵件地址的方法不是很簡單嗎？ –
請使用正確的縮進，否則您的代碼難以閱讀。請刪除這裏不相關的所有信息（如CSS）。並提出一個明確的問題！ –
你收到了哪些錯誤信息？ – halfer
