JQuery 驗證工作，但 submitHandler 不是

Question

我有一個表格，我正在嘗試使用 JQuery Validate 進行驗證，它工作正常。 單擊提交按鈕時，submitHandler 應該 1. 禁用按鈕（以防止多次提交）和 2. 更改按鈕文本。

照原樣，代碼用於驗證，但不調用 submitHandler。

我在這里查看了許多線程，說按鈕必須是 type="submit"，在<form>標簽內等，但無法弄清楚。 該按鈕仍然可以被多次單擊。

有什么幫助嗎？

Answer 1

您可以在客戶端進行驗證並在按鈕的單擊事件上禁用該按鈕。

<script type="text/javascript">

$("#finalSubmit").click(function()
  {
   //do your validation and if correct then disable the button

    $("#finalSubmit").attr("disabled", true);

    //other work if any
   }
  );
</script>

Answer 2

首先，不要使用 jQuery 進行驗證，而是像使用 PHP 等一樣在服務器端進行驗證，並在顯示頁面上反映 output。

這里有一個例子：

index.php

<!DOCTYPE html>
<html>
  <head>
    <title>Site Title</title>
  </head>
  <body>
    <h1>Form</h1>
    <div class="message"></div>
    <form method="post" action="" name="registrationForm">
      First Name <input type="text" name="fname"><br>
      Last Name <input type="text" name="lname"><br>
      Phone <input type="text" name="phone"><br>
      <input type="submit" value="Register" class="regbtn">
    </form>
    <script type="text/javascript" src="js/jquery.js"></script>
    <script>
      $(document).ready(function(){
        $(".regbtn").click(function(){
          var form = document.registrationForm;
          var dataString = $(form).serialize();
          $.ajax({
            type: 'POST',
            url: "your-processing-page.php",
            data: dataString,
            cache: true,
            beforeSend: function(){
              $('.message').hide();
              $(".regbtn").prop('disabled', true).val('Please wait...');
            },
            success: function(data){
              $('.message').html(data).fadeIn();
              $(".regbtn").prop('disabled', false).val('Register');
            }
          });
          return false;
        });
      });
    </script>
  </body>
</html>

你的處理頁面.php

<?php
$fname = (!empty($_POST['fname']))?$_POST['fname']:null;
$lname = (!empty($_POST['lname']))?$_POST['lname']:null;
$phone = (!empty($_POST['phone']))?$_POST['phone']:null;

if($_POST){
  // Perform Checks Here
  if(trim($fname) == ''){
    echo "Please enter first name.";
  }else if(trim($lname) == ''){
    echo "Please enter last name.";
  }else if((strlen($phone)) == 0){
    echo "Please enter a phone number";
  }else if((strlen($phone)) < 10){
    echo "Phone number must not contain less than 10 digits.";
  }else if((strlen($phone)) > 10){
    echo "Phone number must not contain more than 10 digits.";
  }else{
    // If all checks are cleared perform your query
    $stmt = $pdo->prepare("INSERT INTO members(mem_fname, mem_lname, mem_phone)VALUS(:fname, :lname, :phone)");
    $stmt-> bindValue(':fname', $fname);
    $stmt-> bindValue(':lname', $lname);
    $stmt-> bindValue(':phone', $phone);
    $stmt-> execute();

    if($stmt){
      echo "Success! User has been registered.";
    }else{
      echo "Sorry, something went wrong. Please refresh the page and try again!";
    }
  }
}
?>

這是一個完整的答案。 這里：

使用 PHP 在服務器端完成驗證（更好的方法，必須遵循）。
jQuery 禁用提交按鈕以防止單擊后重復提交。
jQuery 在按下提交按鈕時更改按鈕文本值，並在表單提交成功返回時更改回默認值。

注意：以上是一個完全工作的“標准”編碼示例。 這就是你應該編碼的方式。 但是，根據您的需要執行其他必要的檢查。 將上述編碼僅作為示例來構建您自己的代碼。 快樂編碼:)

Answer 3

將提交按鈕名稱更改為其他名稱，因為它會覆蓋表單上的 submit() function，然后此代碼應該適合您（參考）。 ↓↓

 $(document).ready(function() { $("#freebottleform").validate({ rules: { address: { required: true }, city: { required: true }, state: { required: true }, zipcode: { required: true }, phoneNumber: { required: true, // phoneUS: true, digits: true }, }, //Specify the validation error messages here messages: { email: { required: "Please enter email address", email: "Please enter a valid email address" }, phoneNumber: { required: "Please enter your mobile number", digits: "Please enter digits only" } }, submitHandler: function(form) { $("#finalSubmit").attr("disabled", true); $("#finalSubmit").html("Submitting... please wait."); setTimeout(function() { form.submit(); }, 3000); } }); });
