How to create a JSON object in javascript/jquery?

没有什么像JSON object . JSON表示 JavaScript Object Notation (JavaScript对象表示法)，基本上是一个字符串，它编码类似于JavaScript对象常识的信息.

There is nothing like a JSON object. JSON stands for JavaScript Object Notation and is basically a string that encodes information similar to JavaScript's object literals.

但是，您可以使用JSON.stringify(object)创建这样的编码(这将导致 string )，请参见 JavaScript中的JSON .您也可以手动创建这样的字符串，但是它很容易出错，我不建议这样做.

You can however create such an encoding (which would result in a string) with JSON.stringify(object), see JSON in JavaScript. You could also create such a string manually, but it is very error prone and I don't recommend it.

As it is just a string:

var jsonString2 = jsonString;

JSON是交换数据的一种格式，它不是您可以在应用程序中使用的数据结构.

JSON is a format to exchange data, it is not a data structure you can use in an application.
