Serializing and deserializing JSON with JavaScript

This example is similar to the Serializing and deserializing JSON with PHP example. JavaScript is used instead of PHP. Douglas Crockford’s JSON library has been used for serializing and deserializing JSON in JavaScript.

        function jsonExample(){
            var output = document.getElementById('output');

            // Construct the array containing users
            var userArray = new Array();
            userArray[0] = {'name' : 'Joe', 'occupation' : 'Student'};
            userArray[1] = {'name' : 'Bob', 'occupation' : 'Miner'};
            userArray[2] = {'name' : 'Betty', 'occupation' : 'Housewife'};

             // Serialize and print the JSON data
            var serializedUsers = JSON.stringify(userArray);

            output.innerHTML += "Serialized: " + serializedUsers + "\n";

            // Deserialize and print the array
            var deserializedUsers = JSON.parse(serializedUsers);

            output.innerHTML += "Deserialized: " + deserializedUsers + "\n";
<body onload="jsonExample();">
    <pre id="output">


Serialized: [{"name":"Joe","occupation":"Student"},{"name":"Bob","occupation":"Miner"},{"name":"Betty","occupation":"Housewife"}]
Deserialized: [object Object],[object Object],[object Object]
