通过AJAX调用submision不起作用

我想通过AJAX提交电子邮件，但由于某种原因，没有任何工作。我有计数器和计数器检查文件（<script src="mail.js"></script>,jquery和url: "sendmail.php"）是否映射良好。通过AJAX调用submision不起作用

页面重新加载，并且不提交任何内容。我不希望任何页面重新加载，我使用AJAX的原因。

我在做什么错？谢谢大家。

的index.html

<!DOCTYPE html> 
<html lang="en"> 

<head> 
<script src="mail.js"></script> 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

<body> 

    <!-- Content --> 
    <div class="container"> 
     <div class="row"> 
      <div class="span12 subscribe">

       <p>Sign up now to our newsletter and you'll be one of the first to know when the site is ready:</p> 
       <form class="form-inline" action="" method="post">

在mail.js

$(document).ready(function(){  

    $('.btn').click(function(e){ 

    var current_time = 123; 
    var tasktitle = $("input#tasktitle").val(); 
    var dataString = 'current_time='+ current_time + '&tasktitle=' + tasktitle; 

    $.ajax({ 
     type: "POST", 
     url: "sendmail.php", 
     data: dataString, 

     success: function() { 
     $('.title').html(""); 
     $('.success-message').html("✓ Logged!") 
     .hide() 

     .fadeIn(1500, function() { 
      $('success-message').append(""); 
     }); 
     } 
    }); 
    return false; 

    }); 
});

sendmail.php

@ Program-Me-Rev，你对我所做的事有疑问吗？如果是的话，我在这里解释。 –

这是因为序列：

<script src="mail.js"></script> 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

您在mail.js是在后顶部和jQuery 。但是在mail.js中，您使用的是$，而$在那里不可用。 更改序列并重试。

只需要导入jQuery的CDN您在mail.js前

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> 
    <script src="mail.js"></script>

jQuery的必须在调用它之前加载。
