Using Combination Effects with the Scriptaculous DHTML Library - Applying more combination effects
(Page 2 of 4 )
As I clearly stated in the introduction of this article, the Scriptaculous DHTML module comes packaged with a decent number of predefined effects. Some of them were properly reviewed in the preceding article of the series. Nevertheless, there are many that still remain uncovered, so let me offer you a quick explanation of how they work.
I’m going to start this brief review by taking a look at the first group of combination effects, which are called “Shake,” “BlindDown” and “BlindUp” respectively.
With reference to using these brand new effects, a simple implementation for each one of them is shown below. I suggest you to examine the corresponding code samples. Here they are:
(Implementation of Shake effect)

}

Event.observe($('container'),'click',displayEffect,false);
}
Event.observe(window,'load',initializeElement,false);
</script>
<style type="text/css">

}
</style>
</head>
<body>
<div id="container">This element will blind down now</div>
</body>
</html>
(Implementation of BlindUp effect)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

function displayEffect(){
new Effect.BlindUp('container');
}
function initializeElement(){
Event.observe($('container'),'click',displayEffect,false);
}
Event.observe(window,'load',initializeElement,false);
</script>
<style type="text/css">
#container{

}
</style>
</head>
<body>
<div id="container">This element will blind up now</div>
</body>
</html>
As you can see, the three combination effects shown above are indeed easy to follow, since all of them can be implemented by a similar approach. In the first example, a simple DIV element is animated by utilizing the “Effect.Shake” animation, while the second and third cases demonstrate the use of the neat “Effect.BlindUp” and “Effect.BlindDown” effects respectively.
Of course, if you want to see more clearly what these animations look like, simply copy and paste the source code that corresponds to all previous hands-on examples into your favorite text editor and watch them on your own browser. Indeed, this is the best way to appreciate the real potential of a particular animation.
All right, now that you have learned how to use the “Shake,” “BlindUp” and “BlindDown” combination effects that come bundled with Scriptaculous, it’s time to leap forward and continue exploring more DHTML animations.
With reference to this specific topic, in the next section I’ll be talking a close look at some new combination effects, called “SwitchOff, “SlideUp” and “SlideDown,” so if you want to learn how they work, please click on the link below and keep reading.
