Introduction to JavaScript

We will now look into creating a menu using Javascript. We will create a simple menu, which has a number of clickable options. There will be a single image which changes when options is selected. We will also create a function which takes care of changing the menu image. You will be using the images dog.gif, cat.gif and hamster.gif (download from net or make it in photoshop) (more…)

We saw that a MouseOver can be used to change the image displayed when the mouse rolls over an image. This has an interesting application in animated images. Let’s say we have two versions of a GIF image, one of which is a still and one of which is animated. We can use a MouseOver to animate a still image when the mouse rolls over it. In your class files folder you have two images, logoscroll.gif and logostill.gif which can be used to create this effect. (more…)

A mouseover can be used to make an image change when the user rolls their mouse over it. What actually happens is that the browser displays a different image when the mouse is over the text or image. (more…)

Now we’ll take a look at one more type of pop-up box, the message input box. (more…)
