Here’s an example how to store values in an array using JavaScript. This example is the one I used on my site to automatically redirect a page to a predefined set of URLs. I’ve shortened the array to five and change the actual addresses to just “URL”.

<script type=”text/javascript”>
var footSet = new Array();
footSet[1] = “URL”;
footSet[2] = “URL”;
footSet[3] = “URL”;
footSet[4] = “URL”;
footSet[5] = “URL”;

var min = 1;
var max = 5;
var get_seed = Math.floor(Math.random() * (max – min + 1)) + min;

function redirect() {
window.location=footSet[get_seed];
}

setTimeout(‘redirect()’, 10000);
</script>

In this example, there are five arrays stored in the variable labeled “footSet” and every array contains a URL. The “get_seed” variable contains the formula that will generate a random number between one and five. The minimum and maximum value that will be generated is controlled by the variables “min” and “max”. The random value that is generated will be stored in the variable “get_seed”.

When a value is generated, the “setTimeout” command will call the function called “redirect()” after ten seconds (10000). “window.location” will fire up and calling the variable “footSet” bearing the array number “get_seed”.
