Randomization

[mortalc]

How do I get Javascript to randomly allocate a value to a variable (say x)? And how do I get it to randomly allocate a value chosen from a defined set of numbers (say 1,3,5 or <=2)?

You can use Math.random to generate a random number between 0 and 1. If you want to pick a random item in a set, you can put your items in an array and then use Math.random to generate a random array index to use to get the item. There's an article here about making sure that the numbers you get really are random in the range you want to use:http://www.shawnolson.net/a/789/make-javas...dom-useful.html

Could I set the variable with var x=Math.Random?I'll read the article, but in essence?

It's case-sensitive, this will set x to be a number between 0 and 1:var x = Math.random();
