Question

我在我的叔叔网站上有一个在asp页面中创建的表单。 asp页面提交到php页面。这是我可以解决FastHost实际上让电子邮件通过邮件的唯一方法。

我正在尝试在表单的head部分添加验证，但这似乎不起作用。

头部和表格中的代码如下：

JavaScript的：

<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>

                </form>

我将不胜感激任何帮助。感谢

Answer 1

frmname和frmemail需要像输入标签一样使用驼峰。

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

需要知道表单的JavaScript验证是否正确
