我是網頁設計的初學者，這是一個項目，我被授予但無論我做什麼表單都不會提交。即使所有的輸入都是正確的，但我點擊提交後仍然無法執行任何操作。任何幫助表示讚賞。我搜索了一個小時，但沒有任何工作。即使所有的字段被填充和檢查，表格也不會提交
這只是一個簡單的窗體結構。我的主要目標是驗證代碼併發送到PHP腳本。

編輯：只是試圖用這種方式進行調試，而且即使返回值爲true，它似乎也只是通過代碼。
的放出來總是「它不工作」
function validateName() {
var validity = true;
validity &= validateFName();
if (validity === true)
alert("it works FName");
validity &= validateLName();
if (validity === true)
alert("it works LName");
validity &= validateGender();
if (validity === true)
alert("it works Gender");
validity &= validateMonth();
if (validity === true)
alert("it works Month");
validity &= validateDay();
if (validity === true)
alert("it works Day");
validity &= validateYear();
alert("it works Year");
if (validity === true)
return validity;
else
alert("it dosnt works");
}
編輯2.我現在的問題是提交。它會提交表單而不驗證任何輸入。它應該說「請填寫字段」，但它只是去了PHP文件。
你的控制檯給你任何錯誤？ – Luca
使用Chrome或FireFox在validateName函數中設置斷點並驗證該函數是否按預期返回。您可能只想添加簡單的警報或控制檯消息來驗證函數正在被調用。 –
不，沒有@LucaKiebel –
