如何在JavaScript中格式化JSON字符串？
要在JavaScript中格式化HSON字符串，请使用带有一些参数的JSON.stringify()。以下是代码-
示例
var details = {
studentId: 101,
studentFirstName: 'David',
studentLastName: 'Miller',
studentAge:21,
subjectDetails: {
subjectId: 'JavaScript_101',
subjectName: 'Introduction to JavaScript',
}
};
console.log("Not Pretty JSON Format=")
console.log(JSON.stringify(details));
console.log("Pretty JSON Format=")
console.log(JSON.stringify(details, null, 3));要运行以上程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo127.js。
输出结果
这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo127.js
Not Pretty JSON Format=
{"studentId":101,"studentFirstName":"David","studentLastName":"Miller","studentAge":21,"subj
ectDetails":{"subjectId":"JavaScript_101","subjectName":"Introduction to JavaScript"}}
Pretty JSON Format={
"studentId": 101,
"studentFirstName": "David",
"studentLastName": "Miller",
"studentAge": 21,
"subjectDetails": {
"subjectId": "JavaScript_101",
"subjectName": "Introduction to JavaScript"
}
}
