Question

我有一个联系表单（http://www.cig.earthdogpromotions.com/contact.htm），其中刷新验证码的链接不起作用。我已经在基于PHP的联系表单中尝试过，它运行正常。这是一个HTML联系表格我错过了什么或者我应该添加什么才能使它工作？我需要任何特殊的JavaScript代码吗？（如果你给我一些额外的代码，请说明放在哪里。
没有人回答我的问题，所以我想我会尝试将其转换为PHP，并将其iframe转换为HTML。 有什么建议吗？
这是代码

HTML

    <div id="contact-area">
        <br><br>
        <form method="post" action="contactengine.php">

            <input type="text" name="Name" id="Name" placeholder="Please enter required="required" /><br><br>

            <label for="City">Phone:</label>&nbsp;&nbsp;&nbsp;

            <textarea name="Message" rows="20" cols="40" id="Message"enter Message" required="required"></textarea><br><br>

/* Show captcha image in the page html page */

function hexrgb ($hexstr)

  $int = hexdec($hexstr);

  return array("red" => 0xFF & ($int >> 0x10),
           "green" => 0xFF & ($int >> 0x8),

为什么我的验证码的刷新链接不起作用？
