What Is JavaScript JSON Object?
✍: FYIcenter.com
The JSON object is a built-in object in the JavaScript engine
that offers 2 functions to parse and generate JSON text strings:
1. JSON.parse() - Parses a text string from a JSON text string, constructs the JavaScript value. An optional reviver function can be provided to perform a transformation on the resulting object before it is returned.
2. JSON.stringify() - Converts a JavaScript value to a JSON text string, An optional replacer function is specified to replace some values.
Here is a JavaScript code example, JSON-Hello.html, that shows you how to use the built-in JSON object:
<!-- JSON-Hello.html Copyright (c) FYIcenter.com --> <html> <body> <script type="text/javascript"> var object = {"msg":"Hello World!"}; var str = JSON.stringify(object); document.write("<p>JSON text string from JSON.stringify():</p>"); document.write("<pre>str = "+str+"</pre>"); var val = JSON.parse(str); document.write("<p>Value from JSON.parse():</p>"); document.write("<pre>val.msg = "+val.msg+"</pre>"); </script> </body> </html>
Open this example, JSON-Hello.html, in a Web browser. You see the following:
JSON text string from JSON.stringify(): str = {"msg":"Hello World!"} Value from JSON.parse(): val.msg = Hello World!
