Generate Random Numbers in JScript

[Frankie902]

I want to make a random ad generator and I want it to generate a random number, and make someting like a select case in VB and put that html code into the browser

Use Math.random()

[Frankie902]

isnt that just 0 and a 1 randomized?

Try this:

function doRandom(){

var intRand = Math.round((Math.random() * 2));

switch(intRand){

case 1:
alert("1");
break;
case 2:
alert("2");
break;

}//end switch

}//end function

Just multiply the upper range of the number that you want. If you want a number from 0 to 6 then use Math.random()*6. You have to round the number because Math.random() returns a number between 0.0 and 1.0 .

Yeah.

x = minimum number;
y = maximum number;
randNum = (x + Math.random() * y)

So, (1 + Math.random() * 100) would generate a number between 1 and 100.
