FLASH - 檢查文本輸入是否爲空

Question

這是我第一次做FLASH表單驗證，我是FLASH新手。 我有如下操作：（AS 2.0）

bSubmit.onRelease = function() 
{ 
     valiForm(); 
} 
function valiForm() 
{ 
    var sMessage = "Name: " + tName.text + "\nE-mail: " + tEmail.text + "\nPhone: " + tPhone.text; 
    lvSend = new LoadVars(); 
    lvReply = new LoadVars(); 
    var thanks = "Thanks " + tName.text + "your message has been sent"; 
    lvSend.msg = sMessage; 
    lvSend.address = "myemail@ex.ex"; 
    tName.text = ""; 
    tEmail.text = ""; 
    tPhone.text = ""; 
    lvReply.onLoad() 
    { 
     tDone.text = thanks; 
    } 
    lvSend.sendAndLoad('/templates/t3976/mail.php', lvReply, 'POST'); 
} 

現在我才送我要檢查，如果tName字段爲空，如果是警報的一些方法和它的好，然後提交表單的形式。我也想爲nPhone字段做同樣的事情。

感謝您的幫助和對我的基礎英語感到抱歉。

最簡單的方法是在IF

if(tName.text != ""){ 
    // proceed form code here 
} 

你的情況比較字符串，這將是

bSubmit.onRelease = function() 
{ 
     valiForm(); 
} 
function valiForm() 
{ 
    if(tName.text != "" && tPhone.text != ""){ 
    var sMessage = "Name: " + tName.text + "\nE-mail: " + tEmail.text + "\nPhone: " + tPhone.text; 
    lvSend = new LoadVars(); 
    lvReply = new LoadVars(); 
    var thanks = "Thanks " + tName.text + "your message has been sent"; 
    lvSend.msg = sMessage; 
    lvSend.address = "myemail@ex.ex"; 
    tName.text = ""; 
    tEmail.text = ""; 
    tPhone.text = ""; 
    lvReply.onLoad() 
    { 
     tDone.text = thanks; 
    } 
    lvSend.sendAndLoad('/templates/t3976/mail.php', lvReply, 'POST'); 
    } 
}
