Question

以下代码仅获取PHP while循环中最后一个结果的值。任何/所有帮助非常感谢。谢谢！

PHP / HTML / JS：

        <section id="info">
            <?php
                $user = $session->username;
                $q = sprintf("SELECT * FROM mail WHERE UserTo = '%s' ORDER BY SentDate DESC",
                      mysql_real_escape_string($user));
                $getMail = mysql_query($q, $link) or die(mysql_error());

                if(mysql_num_rows($getMail) == 0) {
                    echo "<p>you have no mail</p>";
                }
                else {
                ?>
            <form id="inbox" class="mail">
                <fieldset>
                    <ul>
                        <li style="border: 2px solid purple; width: 100%;">
                            <span style="width: 8%; margin-left: 13%;">Status</span>
                            <span style="width: 15%;">From</span>
                            <span style="width: 45%;">Subject</span>
                            <span style="width: 16%;">Time</span>
                        </li>
                <?php
                        while($mail = mysql_fetch_object($getMail)) {
                            $status         =       $mail->status;
                            $mailId     =       $mail->mail_id;
                            $from           =       $mail->UserFrom;
                            $subject        =       $mail->Subject;
                            $received       =       $mail->SentDate;
                            $theMessage =       $mail->Message;
                        ?>
                        <li class="outerDiv" style="border: 2px dotted purple;">

        </section>

Answer 1

当你说＆＃34;抓住最后一个结果的值时，＆＃34;我猜你在谈论下面一行？

<div class="theMessage" style="display: none;"><?php echo $theMessage; ?></div>

在while()循环之外，所以是的，$theMessage只会保留循环中的最后一个值。

看到你如何在<form>区块中else开始，但在</form>区块之外关闭else，我猜猜你＆＃39;过早结束while和if-else。

首先，您的代码中存在语法错误。转义双引号或使用HTML的单引号。

Answer 3

您使用的是哪个JavaScript库？看起来它可能是JQuery？

如果您希望选择器返回一个数组，那么您需要使用迭代器来处理每个元素。尝试使用每个迭代器函数：http://api.jquery.com/each/

$('.outerDiv').each(function() {
    this.click( function(e) {....

jquery只返回循环时php的最后结果
