Chapter 3. Using JSON in Simple AJAX Applications
In this chapter, we'll look at the part that JSON plays in asynchronous JavaScript and XML (AJAX) applications that provide better responsiveness than older web pages by dynamically loading bits of a web page on demand.
In this chapter, you'll find the following recipes:
- Creating an
XMLHttpRequest
object - Making an asynchronous request for data
- Sending JSON to your web server
- Accepting JSON using Node.js
- Getting the progress of an asynchronous request
- Parsing the returned JSON
- Issuing a web service request using Node.js
