JSON is a format for storing and transporting data. Show JSON is often used when data is sent from a server to a web page. What is JSON?
* The JSON syntax is derived from JavaScript object notation syntax, but the JSON format is text only. Code for reading and generating JSON data can be written in any programming language. JSON ExampleThis JSON syntax defines an employees object: an array of 3 employee records (objects): JSON Example { The JSON Format Evaluates to JavaScript ObjectsThe JSON format is syntactically identical to the code for creating JavaScript objects. Because of this similarity, a JavaScript program can easily convert JSON data into native JavaScript objects. JSON Syntax Rules
JSON Data - A Name and a ValueJSON data is written as name/value pairs, just like JavaScript object properties. A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value: JSON names require double quotes. JavaScript names do not. JSON ObjectsJSON objects are written inside curly braces. Just like in JavaScript, objects can contain multiple name/value pairs: {"firstName":"John", "lastName":"Doe"} JSON ArraysJSON arrays are written inside square brackets. Just like in JavaScript, an array can contain objects: "employees":[ In the example above, the object "employees" is an array. It contains three objects. Each object is a record of a person (with a first name and a last name). Converting a JSON Text to a JavaScript ObjectA common use of JSON is to read data from a web server, and display the data in a web page. For simplicity, this can be demonstrated using a string as input. First, create a JavaScript string containing JSON syntax: let text = '{ "employees" : [' + Then, use the JavaScript
built-in function const obj = JSON.parse(text); Finally, use the new JavaScript object in your page: Example<p id="demo"></p> <script> Try it Yourself ยป Sebuah pendekatan yang mungkin bisa dilakukan adalah beralih pada entri objek dan secara individual keluar dari setiap kunci dan nilai begitu simpul dibangun oleh pustaka pilihan Anda. Mengikuti komentar saya di atas, saya telah menerapkan solusi rekursif sederhana menggunakan Jackson (dari pertanyaan Anda) dan GSON , pustaka yang berbeda di mana objek sedikit lebih mudah dibangun dan kode lebih mudah dibaca .
