通过js跳转页面传递json参数的方式：

const data = {

  name: "John",

  age: 30

};

把jsonx成字符串进行编码

const encodedData = encodeURIComponent(JSON.stringify(data));

window.location.href = "https:baidu.com?data=" + encodedData;

另外一个页面接收：

把编码的字符串进行解密再json序列化成对象

encodedData ='%7B%22name%22%3A%22John%22%2C%22age%22%3A30%7D'

const decodedData = decodeURIComponent(encodedData);

decodedData ='{"name":"John","age":30}'

const data = JSON.parse(decodedData);
