一.核心代码:

const user1String = '{"name": "张三", "age": 30, "gender": "男"}';
const user1Obj = JSON.parse(user1String);
console.log("测试1:", user1Obj.name, user1Obj.age, user1Obj.gender);/*const user2Obj = {"name": "刘红", "age": 25, "gender": "女","courses": ["Math", "Computer"] };*/
const user2Obj = {name: "刘红",age: 25,gender: "女",courses: ["Math", "Computer"]
};
const user2String = JSON.stringify(user2Obj);
console.log("测试2:", user2String);this.txtObj.text = user1Obj.name + "  " + user1Obj.age + "  " + user1Obj.gender + "\n" + user2Obj.name + "  " + user2Obj.age + "  " + user2Obj.gender + "\n" + user2Obj.courses[0] + " " + user2Obj.courses[1];
