Question

我从PHP中的数据库值创建一个数组，然后将其存储到javascript数组中。当我警告数组时，单引号是不可见的，但是当看到PHP时它会显示值的引号。我的代码有什么问题？它应为['1','2','3','4']，但会显示[1,2,3,4]。

<script>
    var values = [
        <?php
            $conn = mysql_connect("localhost","root","") or die ("we couldn't connect!");
            mysql_select_db("test_value");
            $rs = mysql_query("SELECT * FROM test") or die(mysql_error());
            while($row = mysql_fetch_array($rs))
            {
                echo "'".$row['var1']."',";
            }
        ?>
    ];
    window.alert(values);
</script>
