下面是我的code，

<?php
$answers = Array( [0] => 13 [1] => 5 [2] => 6 [3] => 11 );
?>

<script>
    function loadData1(val) {
        var dataToSend = {
            'name': val,
            'ans[]': <? php echo $answers; ?>
        };
        $.ajax({
            type: 'POST',
            data: dataToSend,
            url: '<?php echo JURI::ROOT();?>classfiles/sample.php',
            success: function (data) {
                $('#questions').html(data);
            }
        });
    }
</script>

我想在 sample.php 文件数组值，但我没有得到任何输出。

I want the array values in sample.php file, but I don't get any output.

任何有用的答案是真正的AP preciated。

Any useful answers are really appreciated.

推荐答案

该行：

var dataToSend = {'name' : val, 'ans[]' : <?php echo $answers; ?> } ;

将会打印：

var dataToSend = {'name' : val, 'ans[]' : Array } ;

这将创建一个 JavaScript语法语义错误（ANS =空字符串将公布）。更改为：

which creates a javascript syntax semantic error (ans = empty string will be posted). Change to:

var dataToSend = {'name' : val, 'ans[]' : <?php echo json_encode($answers); ?> } ;

它打印：

var dataToSend = {'name' : val, 'ans[]' : [13,5,6,11] } ;
