Mouseovers, or hovers, are programming techniques that create different effects on a web page when the mouse passes over an object. JavaScript is commonly used to create these effects, which can range from simple text changes to more complex graphics and GUIs. The development of JavaScript in 1995 revolutionized web design and made it more interactive. Hovers can be used for games, business programs, and advertising. The code for creating a hover varies depending on the desired effect, but it involves object-oriented programming. Examples of hovers include clickable text and small windows with advertisements.
A mouseover, sometimes referred to as a rollover, is a bit of programming, usually JavaScript, that creates a different effect on a web page when the mouse passes over a certain object or part of the page (such as a segment of text) . The simpler hover can do things like change the text color if the mouse hovers over that text. Yet mouseovers no longer have to be simple things. Hovering over part of the page can produce exciting graphics or changes to existing graphics or text.
Much of the early internet was considered flat and non-interactive. This changed with the development and release of a new programming language called JavaScript in 1995. Quickly, Netscape Communicator 2.0 was released, which can interpret JavaScript. As a result, many programmers have used JavaScript to create more attractive web pages.
And yet you can find hover examples on the Internet as well. Many programs had changes just by hovering over part of a screen. Many games, especially used them. Hover can also be referred to as a GUI or Graphical User Interface. You’ll find computer games for kids and adults, and even more business-oriented programs use mouse-over or GUIs to develop more interesting effects without all that clicking or double-clicking.
The code for creating a rollover can vary depending on the type of effect you want to create. Essentially with JavaScript, you’re doing something called object-oriented programming. This can be defined as creating code that interacts with other pieces of code in a program.
A very simple hover example, which you will see repeated over and over on internet pages like Wikipedia and on wiseGEEK, is a slight color change and perhaps an underlining of some words on text that is clickable (which may take you to another page or other site). While you are reading a wiseGEEK page, you will notice if you use the mouse that simply by moving the mouse over a certain text, the text will become lighter in color. Most computer users know that this means they can click on text to explore a link to another location.
Hovering doesn’t have to be that simple. WiseGEEK also uses hover which brings up small windows, with advertisements. They do not obscure your reading of the text and can give you information about products or services available to you that are related to the topic you are reading about.
