Web page authors use OnMouseOvers to display text or images when a visitor moves the mouse pointer over a particular part of the page. The Freedom Scientific Product Overview sample page provides an example of a way in which OnMouseOvers are often used. On this page, when a user moves the mouse pointer over one of the product names, which are actually graphic links, the page displays a brief summary of the product. When the user clicks the graphic, the page takes them to the Freedom Scientific Web site to provide additional resources.
NOTE: Two different things happen here depending on whether you simply move the mouse cursor over the graphic or actually activate the link.
JAWS says, "OnMouseOver" when you move to an element with an OnMouseOver. OnMouseOver is an attribute that Web page authors add to HTML elements to enable OnMouseOver functionality.
Open the Freedom Scientific Product Overview sample page. Read through the page first. It is relatively short. Notice that after the first heading, there are four OnMouseOver links which JAWS identifies. Continue reading and you will hear a brief bit of text that begins "This page is designed to demonstrate the use of the OnMouseOver attribute. When a mouse user moves the pointer over the image links ..." Go ahead and read through this text. When you activate an OnMouseOver in the next series of steps, this text will change on the screen.
Activating an OnMouseOver with JAWS actually moves the mouse cursor over the graphic for you. You do this by pressing INSERT+CTRL+ENTER when you hear JAWS announce OnMouseOver links. To see how JAWS interacts with OnMouseOvers on Web pages, do the following:
JAWS Tip: Notice how pressing ENTER and pressing INSERT+CTRL+ENTER can produce very different results with some Web page elements. Pressing INSERT+CTRL+ENTER simulates the effect of moving the mouse pointer over the element, while pressing ENTER simulates the effect of clicking the element.
