Event handler examples

This first example is from the print edition of the article. It is called nav.htm and illustrates the use of JavaScript's navigator object to determine the browser being used to view the page.

This set of examples is a series of HTML pages that introduces each of the JavaScript form elements, as well as their properties and methods. It also includes examples of each of the objects. Finally (as if that weren't enough!), the presentation of the material is also an example of using form objects.

This example, Joe.htm, was written in response to a reader query. The reader was setting up a Web site that would allow users to order food online and have it delivered. The main concern of the reader was displaying the current total before the order was submitted, but it was easier for me to write an entire application than one function. Portions of this example were used in a professional Web site, and with a little better layout (and a real menu), the entire application could easily be used.

This last example is the source code to the object browser. Like the Joe's example, it is prefaced by a text explaining the design considerations that went into its making.
