Example of how JavaScript parses data in JSON format: javascriptjson

This document describes how JavaScript parses JSON data. We will share this with you for your reference. The details are as follows:

1. Use the eval () function provided by JavaScript

Function JsonText1 () {var strJSON = "{'name': 'kevin ', 'age': '23 '}"; // JSON var obj = eval ("(" + strJSON + ")"); // converted JSON object alert (obj. name );}

2. Use a JSON object

① Use the stringify () function of the JSON object to convert the object to JSON

Syntax: var str = JSON. stringify (data );

② Convert JSON into an object using the parse () function of the JSON object

Syntax: var data = JSON. parse (str );

Var jsonStr = ""; // use the stringify () function of the JSON Object to convert the Object to JSONfunction JsonText2 () {var data = new Object; data. name = "Kevin"; data. age = 23; jsonStr = JSON. stringify (data); alert (jsonStr);} // use the parse () function of the JSON object to convert JSON into the function JsonText3 () {var data = JSON. parse (jsonStr); alert (data. name );}
