Scripts

I noticed you can download certain scripts to do certain things in benefit toward the internet. For example, you can dowload a script (javascripts, *.js) to block certain things from the internet, or create effects with the mouse pointer.

But what I don't understand is, what do you do with these files? Where do you put them once they're downloaded, or how do you activate/apply them so they work?

With Javascript you put them into a webpage, inside the HTML:

Code:

<html>
 <head>
  <title>asdf</title>
  <script language="Javascript" src="filename.js"></script>
 </head>
 <body>
  <p>Webpage body</p>
 </body>
</html>

So, you need to be the author of the webpage.

Most people just get annoyed with Javascript "special effects" on webpages though, by the way.

"Scripts" is a very wide term. You can be speaking of web scripts along the lines of the above mentioned JavaScript or the more advanced PHP, Perl and so on scripts. Or you could mean scripts in system languages and many other types all together.

A script is the code of any given program - be it a program like those you run every day on your computer (an instant messenger, your browser, etc.) or a web page.

So, in turn, you don't "use" scripts in any way unless you are the developer of software for any given purpose.

Yeah, with Javascripts they are simply embedded into web pages. Visit some myspace pages to find examples of how to overdo it.

If you want cool effects then you need to make background processes. There are plenty of premade programs (Windows Blind for PC and XShade of Mac) out there or if you want to do it youself I would recommend using C.

The other way javascript is used is Greasemonkey (look it up on wikipedia). It's a Firefox extension that allows javascript to be run and modify/intercept html before it's displayed. You can use it for all kinds of neat things. For instance, if this site ever starts displaying ads, I will write a greasemonkey script to change it into ad-free :-).

Scripts can do all sorts of fun stuff!

Copy this into your address bar.

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R ++}setInterval('A()',5); void(0);
