需要知道這個表單的JavaScript驗證是否正確

Question

我在我的叔叔網站上有一個窗體，它是在一個asp頁面中創建的。 asp頁面提交到一個php頁面。這是我能夠解決FastHost實際讓郵件通過他的郵件的唯一方法。

我想在窗體的頭部添加驗證，但這似乎並沒有工作。

頭部分和形式中的代碼如下：

的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> 

的形式爲：

<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> 
          <td><p>How did you hear about us :</p></td> 
          <td><select name="frmReferral" id="frmReferral" class="block" style="width: 180px">

          </select> 
          </td> 
         </tr> 
         <tr> 
          <td><p>Do you require a call back :</p></td> 
          <td><select name="frmCallback" id="frmCallback" class="block" style="width: 180px">

          <option value="Not Required"<%if frmCallback = "Not Required" then%> selected="true"<%end if%>>Not Required</option> 
          </select> 
          </td> 
         </tr> 
         <tr> 
          <td align="left" valign="top"><p>Enquiry :</p></td> 
          <td><textarea name="frmEnquiry" id="frmEnquiry" cols="27" rows="4" class="textbox" style="width: 180px"><%=frmEnquiry%></textarea></td> 
         </tr> 
         <tr> 
          <td>&nbsp;</td> 
          <td align="right"><input name="submit" type="submit" value=" Send " class="submit"> 
          &nbsp;&nbsp;&nbsp; 
          <input name="reset" type="reset" class="submit"></td> 
         </tr> 
        </table> 
        <p>&nbsp;</p> 
       </form> 

我將不勝感激任何幫助。謝謝

frmname和frmemail需要像在他們的輸入標記一樣駱駝。

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