Javascript 显示JSON数据的最佳方式
我有正在提取的JSON数据：Javascript 显示JSON数据的最佳方式,javascript,php,jquery,json,dynamic,Javascript,Php,Jquery,Json,Dynamic,我有正在提取的JSON数据： { "apiVersion": "0.1", "data": { "roomCount": 12, "rooms": [ { "roomNumber": "204", "occupied": false, "permissions": { "roomCharges": true, "adultContent": true }

你知道我怎样才能让它更有活力吗？谢谢你检查我的问题。如果你还需要什么帮助，请告诉我。我试图解释清楚，如果您需要进一步的信息，请告诉我。虽然代码中没有显示，但您似乎在第一个循环之外第二次循环项目，从而设置变量，重复初始设置值，而不实际“更新”与该行中的值相对应的变量 一个包含变量声明和表输出的简单循环应该可以实现以下功能：
<?php
foreach($output['data']['rooms'] as $info){
$roomNumber = $info['roomNumber'];
$occupied = ($info['occupied'] == 1) ? 'OCCUPIED' : 'VACANT';
$roomCharges = ($info['permissions']['roomCharges'] == 1) ? 'ENABLED' : 'DISABLED';
$adultContent = ($info['permissions']['adultContent'] == 1) ? 'ENABLED' : 'DISABLED';
$roomReport = '<a class="clickhere" href="display_room_report.php?id=' . $info['roomNumber'] .'">Click Here</a>';
?>
<tr>
<td><?php echo $roomNumber ?></td>
<td><?php echo $occupied ?></td>
<td><?php echo $roomCharges ?></td>
<td><?php echo $adultContent ?></td>
<td><?php echo $roomReport ?></td>
</tr>
<?php
}
?>
据我所知，问题是您希望在多个位置重用变量，但如果JSON发生更改，您只需要在一个中心位置对其进行编辑 要实现这一点，您可以使用映射将一个位置的变量映射到您选择的局部变量。在这里的第一段代码的第五行，依此类推，您可以更改并为本地数组选择任何想要的名称。如果JSON中的变量发生了变化，只需更改该变量，您的本地映射仍然是相同的。现在只需更改函数get_data_in_my_format（）中的代码 创建一个data_parser.php或类似的东西
<?php
function get_data_in_my_format(){
$input = json_decode('your data here', true);
$output = array();
foreach($input['data']['rooms'] as $info){
$temp['roomNumber'] = $info['roomNumber'];
$temp['occupied'] = ($info['occupied'] == 1) ? 'OCCUPIED' : 'VACANT';
$temp['roomCharges'] = ($info['permissions']['roomCharges'] == 1) ? 'ENABLED' : 'DISABLED';
$temp['adultContent'] = ($info['permissions']['adultContent'] == 1) ? 'ENABLED' : 'DISABLED';
$temp['roomReport'] = '<a class="clickhere" href="display_room_report.php?id=' . $info['roomNumber'] .'">Click Here</a>';
$output[] = $temp;
}
return $output;
}
//Only insert following line if you want to run the function no matter what
$data_in_my_format = get_data_in_my_format();
您的问题是变量（$roomNumber，$accumposed
等）在初始foreach循环中被覆盖，因此它们最终保存了上一次迭代的值。解决方案可能很简单，但您需要详细说明如何在多个页面中访问这些数据。答案可能很简单，就像phpsinclude
statement一样。我以前试过这样做，结果被投了赞成票。如果你花30秒去读它，它真的会更容易理解。@Steve啊，我明白了。。。是的，你说得对。我想创建一个“data.php”页面，并将其包含在我需要的每个脚本中，比如include'data.php'；一个简单的解决方案是只使用原始代码，将其放在名为datatable.php的文件中，并直接包含它。或者表格/html标记需要在不同的页面之间进行更改吗？@Steve我想我最终可能会这样做。标记将更改，但我可以解决它。谢谢。如果['roomNUMBER']更改为不同的名称，比如['roomID']，那么我仍然需要在两个位置编辑它。如果JSON中的roomNUMBER更改为roomID，则只需在映射中更改它，因此第5行变为：$temp['roomNUMBER']=$info['roomID']；那就是如果我正确理解你的问题，我知道你现在在做什么。是的，这可能真的有用。我会试试看，然后再打给你。谢谢@fiLLipnet
