forms - FLASH - 检查文本输入是否为空

Question

这是我第一次做 FLASH 表单验证，我是 FLASH 新手。我有以下操作：（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');
}

现在在我发送表单之前，我想检查该tName字段是否为空，如果它有某种警报，如果它很好，然后提交表单。我也想为该nPhone领域做同样的事情。

感谢您的帮助，并为我的基础英语感到抱歉。

最简单的方法是在 IF 中比较 String

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

在你的情况下，那将是

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');
   }
}
