Here is another program from teh Shelley Powers book
var dt = new Date();
// get month and increment
var mnth = dt.getUTCMonth();
mnth++;
alert(mnth);
var day = dt.getUTCDate();
if (day < 10) day="0" + day;
var yr = dt.getUTCFullYear();
alert(yr );
var hrs = dt.getUTCHours();
if (hrs < 10) hrs = "0" + hrs;
alert(hrs);
var min = dt.getUTCMinutes();
if (min < 10) min = "0" + min;
alert(min);
var secs = dt.getUTCSeconds();
if (secs < 10) secs = "0" + secs;
alert(secs);
var newDate = yr + "-" + mnth + "-" + day + "T" + hrs + ":" + min;
alert(newDate);
Here is another Shelley Powers tutorial. This one I could nto quite get to work - I got some IS0 8601 dates from wikipedia, and it was fine with teh date that did not have a time added, but for the date with time it kept saying that it was invalid.

<style type="text/css">
#dateSubmit

background-color: #ff0;
width:200px;
text-align: center;
border: 1px solid #ccc;

<script type = "text/javascript">
window.onload = function () {
document.getElementById("dateSubmit").onclick = convertDate;
}
function convertDate() {
var dtstr = document.getElementById("datestring").value;
var convdate = convertISO8601toDate(dtstr);
document.getElementById("result").innerHTML = convdate;
}
function convertISO8601toDate(dtstr) {
//replace anything but numbers by spaces
dtstr = dtstr.replace(/\D/g," ");
//trim any hanging white space
dtstr = dtstr.replace(/\s+$/,"");
// split on space
var dtcomps = dtstr.split(" ");
if (dtcomps.length < 3) return "invalid date";
// if time not provided, set to 0
if (dtcomps.length < 4) {
dtcomps[3] = 0;
dtcomps[4] = 0;
dtcomps[5] = 0;
}
//modify month between 1 based ISO 8601 and zero based date
dtcomps[1]--;
var convdt = new Date(Date.UTC(dtcomps[0], dtcomps[1], dtcomps[2], dtcomps[3], dtcomps[4], dtcomps[5]));
return convdt.toUTCString();
}

<form>

here is a timeout
window.onload=function() {
setTimeout("alert('timeout')",3000);
}
Here is the script and style from the next Shelley Powers tutorial.
<style>
#redbox
{
position: absolute;
left:100px;
top: 100px;
width:200px;
height:200px;
background-color:red;

<script type="text/javascript">
var intervalid=null;
window.onload=function() {

}
function stopStartElement(){
if (intervalid == null) {
var x = 100;
intervalid = setInterval(function(){
x += 5;
var left = x + "px";
document.getElementById('redbox').style.left = left;
}, 100);
}
else {
clearInterval(intervalid);
intervalid = null;
}
}
