我有一个 json 代码，但我不知道如何输入 while 循环。

我已经用代码编辑了内容，但我不知道如何循环一个 json，因为我被insert while on it 这里是示例的链接。

关联

这是我的while循环和查询代码

$query=mysql_query("select * from persons  order by date desc LIMIT 0,10 ");

> <img height=200 width=200 src=' upload/". $test['Image'] ."'/> <a href
> ='profile.php?PersonID=$id'> ".$test['LastName'].", ". $test['FirstName']." ". $test['MiddleName']."</a>

这是我调用代码的脚本文件

> agile_carousel_multiple_slides_visible_example.html
> 
> <script>
> 
>     $.getJSON("agile_carousel_data.php", function (data) {
> 
>         $("#multiple_slides_visible").agile_carousel({
>             carousel_data: data,
>             carousel_outer_height: 230,
>             carousel_height      : 200,
>             slide_height         : 200,
>             carousel_outer_width : 480,
>             slide_width          : 260,
>             number_slides_visible: 3,
>             transition_time      : 330,
>             control_set_1: "previous_button,next_button",

>         });
> 
>     })

尝试了这段代码，但不会输出任何东西

> class='thumb'><img src='{$test['thumb']}' alt='bike is
> nice'></div><p>Agile Carousel Place Holder</p>" } echo
> json_encode($data); ?>

`

客户端，您的循环应如下所示：

//first assign the entire Array to var whatever
for(var i in whatever){
  var eachObject = whatever[i];
  for(var n in eachObject){
    var eachObjectValue = eachOject[n];
  }
}

如果您只想访问，请说whatever数组中第三个对象的第二个值，它看起来像：

whatever[2].content_button or whatever[2]['content_button'];
