我有来自后端的Json结构化数据，当我尝试使用Javascript JSON.parse解析它时，它为我创建了问题。我有多个具有相同密钥的节点，并且在解析时它只给出一个节点。下面是JSON结构。我也为同一个创建了jsfiddle：http://jsfiddle.net/DYZR4/，你可以复制结构并在“http://json.parser.online.fr/”中查看它，看看如何构建JS小牛肉。

答案 0 :(得分：1)
json上不可能有“具有相同键的多个节点”，应该是一个数组。 在解析之前，您需要进行某种数据转换。
查看您的数据，“TODAY”节点是一个元素的所有数组，如果您设法将其转换为包含所有元素的数组，它应该解决您的问题。
答案 1 :(得分：1)
如果您知道每个重复键的内容，并且它们与子数据结构中使用的其他键是唯一的，则可以在解析之前使用正则表达式对其进行修改。
下面的正则表达式依赖于以下事实：为了简单起见，您的密钥将在结束引号（"）和完整冒号（:）之间形成空格。如果不是这种情况，可以升级以处理导致问题的任何情况。
/// load the JSON string into data, shortened example used below
var data = '{ "TODAY": [], "TODAY": [], "UPCOMING": [] }',
keys = ['TODAY', 'UPCOMING'], /// set your keys here
rexp = new RegExp('"(' + keys.join('|') + ')(?=":)', 'g'),
seen = {};
data = data.replace(rexp, function(match){
if ( seen[match] ) {
return match + '_' + (seen[match]++);
}
else {
seen[match] = 1;
return match;
}
});
console.log(data);
/// { "TODAY": [], "TODAY_1": [], "UPCOMING": []}
以上内容至少允许您从客户端获取所有数据，然后您可以逐步执行每个项目并删除添加的_1，_2等等，然后保存在你自己的阵列的其他地方。
如果这些键确实发生在数据集中较低的位置，您会发现它们也已被替换，但在使用数据时这将是一件容易检测和修复的事情。
