我需要解析此JSON文件中所有字段的所有数据.有没有办法在React JS中做到这一点?您能建议我任何一种方法来解析像这样的结构化JSON文件中的数据吗?

I need to parse all data from all fields from this JSON file. Is there a way to do it in React JS? Could you please suggest me any way to parse data from a structured JSON file like this?

推荐答案

React存在于JavaScript中.因此，解析JSON字符串的操作是:

React lives in JavaScript. So parsing a JSON string is done with:

var myObject = JSON.parse(myjsonstring);

如何使用AJAX从某处获取文件是另一个问题.

How to fetch a file from somewhere with AJAX is a different question.

您可以为此使用fetch().参见示例
