Understanding The JavaScript Event Model (part 1) - Game Over (Page 9 of 9 )
And that's about all I have for the moment. In this article, I taught you a little bit about the JavaScript event model, demonstrating the most common event handlers with code snippets and examples. I explained some of the most popular uses of these event handles, including image swapping and URL selection lists, and also demonstrated how they can be used, in combination with simple validation routines, to perform basic form validation on the client side.
If you're new to JavaScript, this article should have demonstrated some of the many uses to which clever developers can put this powerful client-side scripting language. In case you already knew all this, though, don't worry - I'll be back soon with an in-depth look at the internals of the JavaScript event model, explaining the intricacies of the Event object and how it can be used to add even more ammunition to your JavaScript armory. Till then, though, stay healthy...and keep practicing!
