How could I parse through this JSON object in JQuery?
提问by CR47
I have a JSON object that doesn't have a key for the three values given (each is an array) and I want to parse through them. How might I do this in JQuery?
我有一个 JSON 对象，它没有给定三个值的键（每个值都是一个数组），我想解析它们。我如何在 JQuery 中做到这一点？

Your JSON is not valid.
您的 JSON 无效。
Once you create a valid JSON string, parsing it is verysimple.
一旦创建了有效的 JSON 字符串，解析它就非常简单。
Use the following steps:
使用以下步骤：
- remove the commas after the last property of each object
- remove the newlines
- wrap the JSON text in single quotes
- call
jQuery.parseJSON()on the text
- 删除每个对象的最后一个属性后的逗号
- 删除换行符
- 将 JSON 文本括在单引号中
- 呼唤
jQuery.parseJSON()文本
Here's a working fiddle.
这是一个工作小提琴。
It does something like this:
它做这样的事情：
var jsonText = '[ { "cid": "3", "pid": "0", "nid"...} ]';
var jo = $.parseJSON(jsonText);

If you have the JSON in string form, you can use JSON.parse[MDN]to get it in object form, and then do with it what you need to.
如果你有字符串形式的 JSON，你可以使用JSON.parse[MDN]以对象形式获取它，然后用它做你需要的。
Modern browsers have this function natively - no jQuery necessary - but you can also include it yourself from one of these locations:
现代浏览器本机具有此功能 - 不需要 jQuery - 但您也可以从以下位置之一包含它：
