Learn how to transform a JavaScript object into a JSON string and how to transform the JSON string back into a JavaScript object.

Table of contents

Preface

This module is one in a collection of modules designed for teaching ITSE 1356 Introduction to XML at Austin Community College in Austin, TX.

As mentioned in an earlier module, because JSON is an emerging alternative to XML, beginning in the Fall of 2014, the course will include an introductorysection on JSON. The modules in this collection and the online resources pointed to by these modules will be the primary learning resource for the JSON portionof the course.

Preview

I will present and explain three JavaScript scripts in this module. Each script shows how to transform a JavaScript object into a JSON string andhow to transform the JSON string back into a JavaScript object.

The first script deals with a very simple JavaScript object. The second script deals with a slightly more complex JavaScript object that encapsulatesan array of JavaScript objects.

The third script illustrates how to tell the difference between a JavaScript object in object literal format and a JSON string.

In addition to the three scripts described above, I will provide a word of caution regarding a possible terminology issue on a major technical websiteusing a script from that website as an example of the issue.

General background information

Prerequisite knowledge

In order to understand the material in this module, you will need a moderate understanding of HTML and JavaScript programming.
