We are going to create an array of functions we'd like to kick off every 5 seconds. In this example I've used alerts, but this could make an excellent poll for changes to a file.
Once our array is created we can call a function which will perform the actions.
First we need to declare our function and stick it in the <head> of our page.
<script>
function runFunctions(funcArr, delay)
{
setInterval(
function()
{
for(i=0; i<funcArr.length; i++)
{
eval(funcArr[i]);
}
}, delay);
}
</script>
Now we can call our function from within the page <body> or just as easily in the <head>
<script>
var myFuncs=new Array("alert('Mick')","alert('Mack')","alert('Paddy')","alert('Whack')");
runFunctions(myFuncs, 5000);
</script>
