javascript - 想要提醒第二个 json 数据数组

Question

在这里，我得到了两个 json 数组。我确实在第一个 json 数据在 ajax 中发出警报后退出。但是当我要警告第二个 json 数据时，它显示“未定义”。那么，第二个json数据的alert值如何获取呢？

我的代码就像，

$data1['month_result'] = $user_wise_performance;
$data1['total_point'] = $total_point;
$data1['total_earn_point'] = $total_earn_point;
echo json_encode($data1);
exit();
$data2['week_month_result'] = $user_wise_performance;
$data2['week_total_point'] = $total_point;
$data2['week_total_earn_point'] = $total_earn_point;
echo json_encode($data2);
exit();

ajax 调用就像，

jQuery.ajax({
    url: "<?php echo base_url(); ?>grade_tasks/emp_performance",
    data:'',
    type:"GET",
    dataType: "json",
    success:function(data){

        alert(data.total_earn_point);
        alert(data.week_total_earn_point);  //This is not printing the value.

    },
    error:function (){}
});

(更新):在这里，如果我不调用 exit()，我就无法获取 ajax 中的值，那么问题出在哪里呢？

您应该删除第一个 exit(); 或删除两者，我猜您的代码应该是这样的:

$data1['month_result'] = $user_wise_performance;
$data1['total_point'] = $total_point;
$data1['total_earn_point'] = $total_earn_point;
$data1['week_month_result'] = $user_wise_performance;
$data1['week_total_point'] = $total_point;
$data1['week_total_earn_point'] = $total_earn_point;

echo json_encode($data1);

或者尝试使用多维数组，如下面评论中提到的@Ohgodwhy:

$data = 
[
    'data1' => [ 
        'month_result' => $user_wise_performance,
        'total_point' => $total_point,
        'total_earn_point' => $total_earn_point
    ],
    'data2' => [ 
        'week_month_result' => $user_wise_performance,
        'week_total_point' => $total_point,
        'week_total_earn_point' => $total_earn_point
    ]
];

echo $data;

希望这有帮助。
