Summary

The capability to pass data between different windows and frames means that data generated in one part of a web site can be used in another part. In applications in which data entered in one page is required in another page, JavaScript can be used as the agent of communication. While you will see in Part III, “JavaScript and Other Applications and Languages,” that JavaScript in combination with various server-side scripts can do a great deal more in moving data over the web, JavaScript on its own can do a great deal as well.

One of the most interesting challenges for a web designer lies in dynamically creating pages, especially ones using data passed from the originating source. While it might seem a lot easier just to pass data between text or text area windows, you have no control over formatting the materials being passed. By dynamically changing pages, you can pass data and design the page while you’re doing so.
