Could this be done and how???????????

hi, all


is this possible?


could you write a code to get the date and time to generata a rondom number. then, you have an array with multiple colours init and a button that OnClick uses the date and time function to get the number and then that number is matched with the one on the array and, it gives a colour that is nearly random???????????
can this be done and if so how???????????
if you could provide a code i would be most greatfull:)

You don't need to explicitly use JS date/time functions to generate the random number, as in Javascript the random number generator is automatically seeded by the date/time. You should be able to do something like this:

<button onclick="chooseColour()">Choose Colour</button>
<script type="text/javascript">
function chooseColour(){
var colsArray = ["red", "blue", "yellow"];
colVar = colsArray[parseInt(Math.random()*colsArray.length)];
alert(colVar);
}
</script>

hi,



how could i make the documents colour the selected colour???????????????

I believe you can do this instead of the alert:

document.body.style.backgroundColor = colVar;
