Question

我有一个HTML，并与jQuery和PHP链接。jQuery检查字段是否为空，如果字段不是空的，则应该将数据发送到PHP。但这不管用。

​

$(document).ready(function() {
  $("#submit").click(function() {
    var name = $("#name").val();
    var message = $("#message").val();

    $("#returnmessage").empty(); // To empty previous error/success message.
    // Checking for blank fields.
    if (name == '') {
      alert(" Please Fill your name");
    } else if (message == '') {
      alert("Please Fill message");
    } else {
      $.post("xxx.php", { // To php file.
        name: name,
        message: message
      }, function(data) {
        $("#returnmessage").append(data);
        if (data == "We will contact you soon.") {
          $("#form")[0].reset(); // To reset form fields on success.
        }
      });
    }
  });
});

<form name="form" method="post" action="">
  <h4>FEED-BACK FORM</h4>
  <p id="returnmessage"></p>
  <label>Name:  </label>
  <input type="text" id="name" /><br>
  <label>Message:  </label>
  <input type="text" id="message" /><br>
  <input type="button" id="submit" value="Submit"/>
</form>

PHP代码是：

if(!isset($_POST['submit']))
       {
    //Need to submit the form.
    exit;
       }
$name = $_POST['name'];
$message = $_POST['message'];

$email_body ="Dear sir,\n".
"Name: $name\n". 
"Message:    $message\n";

//Email sending to
$email_from = 'xxx@xxx.xxx';
$email_subject = "my-form";
$to = "xxx@xxxx";
$headers = "From: $email_from \r\n";

//Send the email!
mail($to,$email_subject,$email_body,$headers);

我试过你的代码，但没有错误。运行代码。使用jQuery库的是哪个版本？

请你试一下

jQuery lib2.2 https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js

就像这样？

 jQuery(document).ready(function() {
  jQuery("#submit").click(function() {
    var data_name = jQuery("#name").val();
    var data_message = jQuery("#message").val();
    jQuery("#returnmessage").empty(); // To empty previous error/success message.
    // Checking for blank fields.
      if (data_name == '' ) {
        alert(" Please Fill your name");
      } else if(data_message == '' ) {
        alert("Please Fill message");
      } else { 
        jQuery.post("xxx.php", { // To php file.
            name: data_name, message: data_message
        }, function(data) {
            jQuery("#returnmessage").append(data); 
          if (data == "We will contact you soon.") {
            jQuery("#form")[0].reset(); // To reset form fields on success.
          }
        });
    }
  });
});
