我想弄清楚爲什麼表單的「提交此表單」按鈕沒有帶我到<form ... action="submit form.html" method="get">屬性中指定的另一個HTML頁面，不僅如此，而且當我輸入錯誤的名字，電子郵件地址和訂單號時，和訂單日期，它不會返回我使用JavaScript在我的if-else代碼中指定的JavaScript消息。當我點擊它時，爲什麼我的表單提交按鈕不會進入下一頁？
這是我在表單上使用的JavaScript代碼。
var $ = function (id)
{
return document.getElementById(id);
}
var submitForm = function()
{
var FirstName= $("firstName").value;
var OrderNumber= $("orderNumber").value;
var DateOfOrder= $("date_of_order").value;
var emailAddress= $("email_address").value;
var isValid=true;
if(FirstName !== "Cherry", "Micheal", "Sandra", "Cookie")
{
$("firstname_error").firstChild.nodeValue=
"This person does not exist.";
isValid=false;
} else{ $("firstname_error").firstChild.nodeValue="";}
if(OrderNumber !== 3134, 4234, 9234, 3566)
{
$("orderNumber_error").firstChild.nodeValue="Invalid Order Number.";
isValid=false;
} else{ $("orderNumber_error").firstChild.nodeValue="";}
if(DateOfOrder !=='12-07-23', '15-04-24', '16-02-01', '14-01-12')
{
$("date_of_order_error").firstChild.nodeValue="Date doesn't exist in
system";
isValid=false;
} else{ $("date_of_order_error").firstChild.nodeValue="";}
if(emailAddress !="[email protected]", "[email protected]",
"[email protected]", "[email protected]")
{
$("email_address_error").firstChild.nodeValue="The email doesn't exist";
isValid=false;
} else{ $("email_address_error").firstChild.nodeValue="";}
if(isValid)
{
\t //submit the form if all entries are valid
\t $("cookie_form").submit();
}
}
window.onload = function()
{
$("form_submission").onclick = submitForm; \t
$("email_address").focus();
