Help with JavaScript for Greasemonkey - Overclock.net

nachosanchezz · 10-03-09

I want to write a java script for Grease Monkey so that it will load a specific address in a loop, and have a delay of a random length of time between, say, 10-20 minutes.

Can anyone please tell me how to do this, and possibly explain what each part of the script does.

Thanks!!

EDIT: Essentially what I need is: javascript commands to load a url, to wait for a certain amount of time, to generate a random number, and to loop the script? I have next to no knowledge of how this is suppose to work, so please tell me if any part of my question doesn't make sense.

Here's something I just wrote.

You choose the URL's you want in the array, then it will randomly load them.

The timeout is set to 600000 Miilliseconds (10 minutes).

Code:

// ==UserScript==
// @name           Random Url's
// @namespace      http://userscripts.org
// @include        *
// ==/UserScript==

//declare variables
var rand1,rand2;

//URL array, add as many as you want.
var urls=['http://google.com','http://youtube.com','http://overclock.net']

//set rand2 to a random number between 0 and 600000 milliseconds
rand2=Math.floor(Math.random()*600000);

//Tell browser to load the load_url function after the random time (rand2)
window.setTimeout(load_url,rand2);

//And here's the function that changes the page
function load_url(){
        //get a random number to choose a random url
	rand1=Math.floor(Math.random()*urls.length);
        //make the page go to the random url
	location.href=urls[rand1];
	}

	}

Thank you very much! Much appreciated.

I just realised I have no idea of how to actually install/activate a user script so Greasemonkey will implement it.... Anyone care to explain please?

Right click on the little greasemonkey icon.
Click New User Script.

Choose a name.
Put down * for includes.
Then Click OK.

When the text editor opens, just copy and paste the script you want.

When you're browsing the internet and you open a *.user.js file, Greasemonkey will automatically install the script for you.
