JavaScript加載新頁面問題

Question

我期待的是如果用戶填寫表單，它將提供對新位置的訪問。

<script language="JavaScript" type="text/javascript">  
<!--  
function validateForm(theForm) {  
var firstname = theForm.firstname.value; 
var lastname = theForm.lastname.value;  
var email = theForm.email.value;  
if (firstname == "") {  
    alert("Please fill in your First Name.");  
    theForm.firstname.focus();  
    return false;  
} 
if (lastname == "") {  
    alert("Please fill in your Last Name.");  
    theForm.lastname.focus();  
    return false;  
} 

if (email == "") {  
    alert("Please fill in your email address.");  
    theForm.email.focus();  
    return false;  
}  
return true;  
} 

我知道這部分是錯誤的，但我不知道如何去做。任何幫助將是不錯..

if lastname="" 
if firstname="" 
if email="" 
load('www.google.com'); 

Answer 1

if (validateForm(theForm)) window.location = 'http://www.google.com'; 

等同於使用

if (validateForm(theForm)) window.location.href = 'http://www.google.com'; 

雙方將工作，所以選擇你喜歡哪一個。

Answer 2

if lastname="" 
if firstname="" 
if email="" 
load('www.google.com'); 

成爲

if ((lastname == "") && (firstname == "") && (email == "")) { 
    window.location = "http://www.google.com"; 
}
