我必须使用javascript函数显示重定向页面，增量为1。但是当我尝试这个时，我得到了 NaN Error 。谁能帮我解决问题。我在下面附上了我的来源。像这个 quiz.php?qusId=NaN。

    <script type="text/javascript">
        function handler(var1,quizId) {
            alert(var1);
            var id = parseInt(quizId);
            window.location = "quiz.php?qusId="+parseInt(quid(id));
        }
        function quid(quzId){
            if(quzId == 1){
                return 1;
            }else{
                return quzId++;
            }
        }
    </script>
</head>
<body>
    <?php 
        $qusId=$_GET['qusId'];
        ?>
        <form action="test.php" method="POST">
            <?php
                $result = select("SELECT * FROM questions WHERE question_id='$qusId'");
                //$row = mysql_fetch_array($result);
                $i=$_GET['qusId'];
                while($row = mysql_fetch_array($result))
                {
                    ?>
                        <table width="581" height="299" border="1">
                            <tr>
                                <td>Union Assurance Questionnaire</td>

在您的点击处理程序中，您有

handler('<?php echo $row1["feedback"]; ?>,<?php echo $qusId;?>')

您将单引号放在错误的位置 - 它作为单个参数传递到您的“处理程序”函数中。请尝试：

handler('<?php echo $row1["feedback"]; ?>',<?php echo $qusId;?>)
