script.aculo.us – Visual Effects

script.aculo.us – Visual Effects The script.aculo.us effects are divided into two groups − Core Effects The following six core effects are the foundation of the script.aculo.us Visual Effects JavaScript library. Effect.Opacity Effect.Scale Effect.Morph Effect.Move Effect.Highlight Effect.Parallel All the core effects support various common parameters as well as effect-specific parameters and these effect names are case-sensitive. All the effect-specific Common Parameters have been discussed in this tutorial along with the effects. Combination Effects All the combination effects are based on the five Core Effects, and are thought of as examples to allow you to write your own effects. Usually these effects rely on the parallel, synchronized execution of other effects. Such an execution is readily available, hence creating your own combined effects is very easy. Here is a list of Combination Effects − Effect.Appear Effect.Fade Effect.Puff Effect.DropOut Effect.Shake Effect.SwitchOff Effect.BlindDown Effect.BlindUp Effect.SlideDown Effect.SlideUp Effect.Pulsate Effect.Squish Effect.Fold Effect.Grow Effect.Shrink Additionally, there”s the Effect.toggle utility method for elements you want to show temporarily with an Appear/Fade, Slide or Blind animation. Effect.toggle Library Files Required for Effects To use the effect capabilities of script.aculo.us, you will need to load the effects module. So, your minimum loading for script.aculo.us will look like this: <html> <head> <title>script.aculo.us effects</title> <script type = “text/javascript” src = “/javascript/prototype.js”></script> <script type = “text/javascript” src = “/javascript/”effects.j”></script> </head> <body> … </body> </html> Call Effect Functions The proper way to start a core effect is usually with the new operator. Depending on your preferences, you can use one of two syntaxes − Syntax new Effect.EffectName(element [, requiredArgs ] [ , options ] ) OR element.visualEffect(”EffectName” [, requiredArgs ] [,options]) These two syntaxes are technically equivalent. Choosing between the two is mostly about your personal sense of code aesthetics. Example Here are two equivalent calls, so you can see how the syntaxes are related, which are very much interchangeable − new Effect.Scale(”title”, 200, { scaleY: false, scaleContent: false }); OR $(”title” ).visualEffect(”Scale”, 200, { scaleY:false, scaleContent:false }); Print Page Previous Next Advertisements ”;
