How to maintain order when parsing JSON from Javascript?
提问by TehWan
The data I am sending my page is encoded in JSON, parsed using Javascript then displayed in an HTML SELECT element using a loop. The data arrives already sorted, but I am having issues keeping the correct order when decoding the JSON string, which nullifies the sorting applied on the data.
我发送给我的页面的数据以 JSON 编码，使用 Javascript 解析，然后使用循环显示在 HTML SELECT 元素中。数据到达时已经排序，但我在解码 JSON 字符串时遇到了保持正确顺序的问题，这会使应用于数据的排序无效。
Sample data: {"test":{"4":"first","5":"second","3":"third"}}
样本数据： {"test":{"4":"first","5":"second","3":"third"}}
Using jQuery's JSON parser and Javascript's eval() function, I am getting the following results:
使用 jQuery 的 JSON 解析器和 Javascript 的 eval() 函数，我得到以下结果：
{"test":{"3":"third","4":"first","5":"second"}}
{"test":{"3":"third","4":"first","5":"second"}}
It is not possible to modify the format of the data and the keys ("4", "5", "3") must remain in the same order. The real data is much more complex, but this sample illustrates very well my issue.
无法修改数据的格式，并且键（“4”、“5”、“3”）必须保持相同的顺序。实际数据要复杂得多，但此示例很好地说明了我的问题。

Use an array if you want to keep the order. That should be the only way to maintain the order in javascript.
如果您想保持顺序，请使用数组。这应该是在 javascript 中维护订单的唯一方法。
