使用javascript的php聯繫表格中的必填字段

Question

我需要對以下字段強制使用此表單。

名稱： 手機 郵箱地址： 地址1號線： 2行地址： 城市/城鎮： 縣： 郵編： 服務請求的問題： 項目/ PC型號： 設備類型： 發票號碼：

我已經嘗試使用JavaScript將它放在標題和索引文件中，但不能看到讓他們中的任何一個工作。任何想法或建議將不勝感激。我不想使用PHP或不得不重新編寫當前的聯繫表單。

的JavaScript：

<script language="javascript" 
type="text/javascript"> 

<!-- hide script from older browsers 
function validateForm(myform) 
{ 

if(""==document.forms.myform.sreq_name.value) 
{

return false; 
} 

if(""==document.forms.myform.sreq_cellphone.value)

return false; 
} 

if(""==document.forms.contact.sreq_phone.value) 
{ 
alert("Please enter your phone number."); 
return false; 
} 

} 
stop hiding script --> 
</script>

更正你的腳本

<script type="text/javascript"> 
function validateForm(myform) { 
    var ele = myform.elements 
    if("" == ele['sreq_name'].value) { 
    alert("Please enter your full name."); 
    return false; 
    } 

    if("" == ele['sreq_cellphone'].value) { 
    alert("Please enter your email address."); 
    return false; 
    } 

    if("" == ele['contact.sreq_phone'].value) { 
    alert("Please enter your phone number."); 
    return false; 
    } 
} 
</script> 

如果在你的函數，那麼形式未經驗證自動提交任何錯誤。

您還需要在服務器端進行驗證。
