Html AJAX PHP表单可以'；t重新发送数据/始终在电话号码字段停止

我试图为我的网站制作一个简单的联系方式，所以我从CodeCanyon买了一个。在没有收到作者缓慢而稀少的帮助后，我请求你们的帮助

基本上，这是一个非常简单的联系方式，但我不太擅长编码，所以不管怎样，它都会困扰我。这是HTML代码

<div id="contact" class="clearfix"><!-- contact -->

<h1><img name="logo" src="" width="300" height="50" alt="" style="background-color: #3366FF" /></h1><p class="txn">Lorem ipsum dim sum sum.</p>  

        <div id="message"></div>
        
        <form method="post" action="contact.php" name="contactform" id="contactform">
        
        <fieldset>
                
        <legend>Please fill in the following form to contact us</legend>
    
        <label for=name accesskey=U><span class="required">*</span> Your Name</label>
        <input name="name" type="text" id="name" size="30" value="" /> 
    
        <br />
        <label for=email accesskey=E><span class="required">*</span> Email</label>
        <input name="email" type="text" id="email" size="30" value="" />
    
        <br />
        <label for=phone accesskey=P><span class="required">*</span> Phone</label>
        <input name="phone" type="text" id="phone" size="30" value="" />
    
        <br />
        <label for=subject accesskey=S>Subject</label>
        <select name="subject" type="text" id="subject">
          <option value="Support">Support</option>
          <option value="a Sale">Sales</option>
          <option value="a Bug fix">Report a bug</option>
        </select>
    
        <br />
        <label for=comments accesskey=C><span class="required">*</span> Your comments</label>
        <textarea name="comments" cols="40" rows="3"  id="comments" style="width: 350px;"></textarea>
                        
        <p><span class="required">*</span> Are you human?</p>
                
        <label for=verify accesskey=V>&nbsp;&nbsp;&nbsp;3 + 1 =</label>
        <input name="verify" type="text" id="verify" size="4" value="" style="width: 30px;" /><br /><br />
    
        <input type="submit" class="submit" id="submit" value="Submit" />
        
        </fieldset>
    
        </form>

模板中提供的JavaScript文件……实际上没有改变

jQuery(document).ready(function(){

$('#contactform').submit(function(){

    var action = $(this).attr('action');
    
    $("#message").slideUp(450,function() {
    $('#message').hide();
    
    $('#submit')
        .after('<img src="assets/ajax-loader.gif" class="loader" />')
        .attr('disabled','disabled');
    
    $.post(action, { 
        name: $('#name').val(),
        email: $('#email').val(),
        phone: $('#telephone').val(),
        subject: $('#enquiry').val(),
        comments: $('#message').val(),
    },
        function(data){
            document.getElementById('message').innerHTML = data;
            $('#message').slideDown('fast');
            $('#contactform img.loader').fadeOut('slow',function(){$(this).remove()});
            $('#contactform #submit').attr('disabled',''); 
            if(data.match('success') != null) $('#contactform').slideUp('slow');
            
        }
    );
    
    });
    
    return false; 

    });

    });

jQuery（文档）.ready（函数（）{
$（'#contactform'）。提交（函数（）{
var action=$（this.attr（'action'）；
$（“#消息”）.slideUp（450，函数（）{
$（“#消息”）.hide（）；
$（“#提交”）
.在（“”）之后
.attr（'disabled'，'disabled'）；
$.post（操作，{
名称：$（'#name'）.val（），
电子邮件：$（'#email'）.val（），
电话：$（“#电话”）.val（），
主题：$（“#查询”）.val（），
注释：$（“#消息”）.val（），
},
功能（数据）{
document.getElementById（'message'）.innerHTML=data；
$（'消息'）.slideDown（'快速'）；
$（'#contactform img.loader'）.fadeOut（'slow'，function（）{$（this.remove（）}）；
$（'contactform'submit'）.attr（'disabled'，''）；
if（data.match（'success'）！=null）$（'contactform'）.slideUp（'slow'）；
}
);
});
返回false；
});
});

然后是我得到的联系人php文件

<?php

发布数据后，“提交”按钮将被禁用。这就是为什么你不能重新发布它
$（'contactform'submit'）.attr（'disabled'，''）

使用正确的输入字段id
电话：$（“#电话”）.val（）

这将始终为空，因为没有具有此id的组件具有相同类型的错误。没有id查询或消息的元素

主题：$（“#查询”）.val（），
注释：$（“#消息”）.val（）

在检索值时，请确定html组件的名称和id

谢谢
谢谢！我已将提交按钮的属性更改为启用。但是现在我得到了答案，请输入一个主题错误？
