Question

首先，我是一个超级棒的编码，很抱歉！

在我目前的工作中，我继承了一些超重的联系表格，并在第一次加载着陆页时造成延迟。我一直试图整理一个更干净的版本，这在大多数情况下都很好，但是表单中的下拉列表并不是必需的字段。占位符文本显示我隐藏的“状态”，因为我希望用户需要从下面的列表中进行选择，但是当您提交表单而不选择任何内容时，生成的电子邮件会显示为“状态：状态”

我在这里做错了吗？如果有人有任何建议，我们将不胜感激。

谢谢！伊恩

Answer 1

您不应该为state选项赋予任何值，以防止用户保留此选择未指定。

所以删除value =“state”就像在下面的代码行中一样：

<option hidden="" value="" disabled selected>State</option>

Answer 2

不要为<option hidden="" value="State" disabled selected>State</option>

设置值

将该值属性设为空。

<option hidden="" value="" disabled selected>State</option>

然后只需要所需的字段。

Answer 3

使用您的HTML代码，您不得在隐藏，禁用，已选择的选项中放置value的任何内容。如果required等于空，value选项最有效。此外，由于您似乎正在使用HTML5，因此您现在可以自行添加hidden，类似于您放置disabled和selected的方式。因此，您的HTML代码可能是这样的：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Contact Form</title>
    <link rel="stylesheet" href="css/style.css">
</head>
<body>
    <div class="container">
        <div class="contact">
            <form id="contact" method="post" action="/forms/contact-form.php">
                <input name="name" placeholder="Full Name: " type="text" tabindex="1" required autofocus>
                <input name="email" placeholder="Email: " type="email" tabindex="2" required>
                <input name="phone" placeholder="Phone: " type="tel" tabindex="3" required>
                <input name="organization" placeholder="Organization: " type="text" tabindex="4" required>
                <input name="title" placeholder="Position Title: " type="text" tabindex="5" required>
                <select name="state" tabindex="6" required> 
                    <option value="" disabled hidden selected>State</option>
                    <option value="NSW">NSW</option>
                    <option value="VIC">VIC</option>
                    <option value="QLD">QLD</option>
                    <option value="WA">WA</option>
                    <option value="SA">SA</option>
                    <option value="TAS">TAS</option>
                    <option value="ACT">ACT</option>
                    <option value="NT">NT</option>
                </select>
                <textarea name="message" placeholder="Message: " tabindex="7" required></textarea>
                <button name="submit" type="submit" id="contact-submit" data-submit="...Sending">Submit</button>
            </form>
        </div>
    </div>
</body>
</html>

Answer 4

是的，您可以在HTML5中使用必需属性来选择Tag。但请记住，第一个值应为空。

<select name="state" required>  
    <option value="" disabled hidden selected>State</option>
    <option value="NSW">NSW</option>
    <option value="VIC">VIC</option>
    <option value="QLD">QLD</option>
    <option value="WA">WA</option>
    <option value="SA">SA</option>
    <option value="TAS">TAS</option>
    <option value="ACT">ACT</option>
    <option value="NT">NT</option>
</select>

表单上的下拉列表不是必需的部分
