我有一个表格，我需要在提交之前填写所有字段。目前，正在验证这些字段以检查它们是否为空白。但是，如果在没有在表单发送的字段中输入任何值的情况下按下提交按钮，所有字段都返回空白（例如姓名：电话：等）。我尝试在表单字段中添加 HTML5“必需”属性，但这并不能解决非 HTML5 兼容浏览器或 IE 的问题。

我想知道您是否可以帮我解决这个问题...谢谢！

在我的页面顶部，我放了：

 <script>
$(function(){
$('#message_form').validate({
submitHandler: function(form) {
    $(form).ajaxSubmit({
    url: 'process.php',
    success: function() {
    $('#message_form').hide();
    $('#contact_form').append("<p id='message_form_thanks'>Thanks! Your request has been sent.</p>")
    }
    });
    }
});         
});
</script>

process.php 代码是：

<?php
// Get Data 
$name = strip_tags($_POST['name']);
$phone = strip_tags($_POST['phone']);
$email = strip_tags($_POST['email']);
$message = strip_tags($_POST['message']);
// $url = strip_tags($_POST['url']);

// Send Message
mail( "mailto:postmaster@domain.com", "Contact Form Submission",
"Name: $name\nPhone: $phone\nEmail: $email\nMessage: $message\n",
"From: Website Form Enquiry <$email>" );
?>

我的表单代码是：

                <form id="message_form" method="post">
                <div class="success">Contact form submitted! <strong><br>We will be in touch soon.</strong></div>
                <fieldset>
                    <label class="name"><span class="formlabel">  Name:</span>
                        <input type="text" name="name" placeholder="Please provide your full name" required>
                        <span class="error">*This is not a valid name.</span>
                        <span class="empty">*This field is required.</span>
                        <span class="clear"></span>
                    </label>
                    <label class="phone"><span class="formlabel">Phone:</span>
                        <input type="text" name="phone" placeholder="Example: (555) 555-5555" required>
                        <span class="error">*This is not a valid phone number.</span>
                        <span class="empty">*This field is required.</span>
                        <span class="clear"></span>
                    </label>
                    <label class="email"><span class="formlabel">Email:</span>
                        <input type="text" name="email" placeholder="Please provide your email address" required>
                        <span class="error">*This is not a valid email address.</span>
                        <span class="empty">*This field is required.</span>
                        <span class="clear"></span>
                    </label>
                    <span class="formlabel_message">Message:</span>
                    <label class="message">
                        <textarea name="message" placeholder="Please enter your message here" style="margin-top:0;" required></textarea>
                        <span class="error">*The message is too short.</span>
                        <span class="empty">*This field is required.</span>
                        <span class="clear"></span>
                    </label>
                    <div class="buttons-wrapper"><a class="button-2 mobile_noshow" data-type="reset">reset</a>
                    <input type="submit" name="submit" class="button-2" style="margin:0 0 0 7px;border:none;" id="submit" value="Send" /></div>
                </fieldset>
            </form>

您需要进行一些验证，我可能会禁用提交按钮，直到填写所有字段，如下所示：

$('#message_form #submit').attr('disabled', 'disabled');  
    $('#message_form input,textarea').on('keyup', function(){
        if($('#name').val() && $('#phone').val() && $('#email').val() && $('#message').val()){
             $('#message_form #submit').removeAttr("disabled");           
        }
        else{
           $('#message_form #submit').attr('disabled', 'disabled');
        }
    });
