我使用000webhost webmail接收使用联系表单的电子邮件,但它不起作用.

contact.php

     <form  action="mailer.php" method="post">
<p>Name:</p>
<input type="text" name="name" />
<p>E-mail:</p>
<input type="text" name="email" />
<p>Subject:</p>
<input type="text" name="subject" />
<p>Message:</p>
<textarea name="message"></textarea></p>
<input class="send" type="submit" value="Send" name="submit">
</form>

mailer.php

     <?php

$to = "xxx@xxxxx.com";
$subject = "Support requested by ".$_POST['name'];
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$message = $_POST['message'];

$headers = 'From: '.$_POST['email'].'' . "\r\n" .
   'Reply-To: '.$_POST['email'].'' . "\r\n" .
   'X-Mailer: PHP/' . phpversion();

$body = $message;

@mail($to, $subject, $body, $headers );
header( 'Location:thankyou.php' ) ; //replace with …

以下代码是按字母顺序对表单列表选项进行排序,但'getElementsByClassName()'不起作用,我无法弄清楚原因.

我正在使用最新的jQuery.

window.onload=function(){
    function sortlist() {
        var cl = document.getElementsByClassName('car_options');
        var clTexts = new Array();

        for(i = 1; i < cl.length; i++) {
            clTexts[i-1] =
                cl.options[i].text.toUpperCase() + "," +
                cl.options[i].text + "," +
                cl.options[i].value;
    }   
    clTexts.sort();

    for(i = 1; i < cl.length; i++) {
        var parts = clTexts[i-1].split(',');
        cl.options[i].text = parts[1];
        cl.options[i].value = parts[2];
    }
    sortlist();
}

在身体部分

     <form action="" method="get">

        <p><label for="car_make"></label>
          <select id="car_make"  class="car_options" name="car_make"> 

            <option value="">By Make</option>
            <option value="Vauxhall">Vauxhall</option>
            <option value="BMW">BMW</option>
            <option value="Toyota">Toyota</option>
            <option value="Lexus">Lexus</option>
            <option value="Audi">Audi</option> …
