需要知道表单的JavaScript验证是否正确

我叔叔的网站上有一个在asp页面中创建的表单。asp页面提交到php页面。这是我唯一能绕过FastHost的方法，让电子邮件真正进入他的邮件

我试图在表单的head部分添加验证，但这似乎不起作用

标题部分和表格中的代码如下：

JavaScript:

<script type="text/javascript">

function validateForms() {
  var x=document.forms["myForm"]["frmname"].value;
  if (x==null || x=="") {
    alert("First name must be filled out");
    return false;
 }

  var x=document.forms["myForm"]["frmemail"].value;
  var atpos=x.indexOf("@");
  var dotpos=x.lastIndexOf(".");
  if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length) {
    alert("Not a valid e-mail address");
    return false;
  }
} 

</script>

表格：

<form action="sendmail.php" onsubmit="return validateForms();" id="myForm" method="post">
                    <table  border="0" cellpadding="2" cellspacing="0" class="text">
                        <tr>
                            <td><p>Name : * </p></td>
                            <td><input name="frmName" id="frmName" type="text" class="textbox" value="<%=frmName%>" size="35" title="Required" /></td>
                        </tr>
                        <tr>
                            <td><p>Email : *</p></td>
                            <td><input name="frmEmail" id="frmEmail" type="email" class="textbox" value="<%=frmEmail%>" size="35" title="Required" /></td>
                        </tr>
                        <tr>
                            <td><p>Phone : </p></td>
                            <td><input name="frmPhone" id="frmPhone" type="text" class="textbox" value="<%=frmPhone%>" size="35" /></td>
                        </tr>
                        <tr>
                            <td><p>Address :</p></td>
                            <td><input name="frmAddress" id="frmAddress" type="text" class="textbox" value="<%=frmAddress%>" size="35" /></td>
                        </tr>
                        <tr>

我将非常感谢您的帮助。谢谢

frmname和frmemail需要像在输入标签中一样用驼峰大小写

var x=document.forms["myForm"]["frmName"].value;
var x=document.forms["myForm"]["frmEmail"].value;

什么不起作用？发生了什么事？你有一个我们可以看到的功能性网站吗？@BrianHoover在标题部分甚至没有阅读JavaScript，表单只是提交到主机提供的PHP页面。这个PHP页面有它自己的电子邮件验证，但我希望它事先阅读JavaScript。谢谢，很好。我半睡半醒，4分钟后我会接受你的回答
