javascript - $_POST 不从 .post 读取变量值

Question

这是我的 javascript 代码:

function submitForm() {
    var name = document.getElementsByName('name').value
        ,email = document.getElementsByName('email').value
        ,subject = document.getElementsByName('subject').value
        ,body = document.getElementsByName('body').value;
    
    $.post('php/sendForm.php', {name: name,email: email,subject: subject,body: body});

}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
  <div class="form-group inline-block" method="post" action="php/sendForm.php" >
    <input type="text" class="form-control" name="name" placeholder="Name"></div>
  <div class="form-group inline-block">
    <input type="email" class="form-control" name="email" aria-describedby="emailHelp" placeholder="Enter email">
    <small id="emailHelp" class="form-text text-muted">Send me an email!</small> 
    <input type="text" class="form-control" name="subject" aria-describedby="emailHelp" placeholder="Subject">
  </div> 
  <div class="form-group">
    <label for="exampleTextarea">Message</label>
    <textarea class="form-control" name="body" rows="3">
    </textarea>  
  </div>
  <button onclick="submitForm()" type="submit" class="btn btn-primary">Submit                                           </button>
</form>

所有这些都是为了让 php/sendForm.php 读取。 但是，我似乎无法读取 php 文件中的名称、电子邮件、主题和正文变量。 这是 php 代码:

$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$body = $_POST['body'];
// The message
$message .= $email. $name. $body ;

Answer 1

您没有对事件调用 preventDefault。这意味着表单已提交(使用 GET 和它自己的 URL，因为这些是默认值)

尝试:

<button onClick="submitForm(); return false;">
