How do you create a javascript number generator using the year,month,day, hour, and minute set on my computer?


And if possible, how do i format this number to be 10 characters in length with the format of YYMMDDHHmm?

Y=year,M=month,D=day,H=hour,m=minute

Please take this

<html>
<body>
<script language="javascript">
function make2digit(value) {
     if (parseInt(value) < 10) { return ('0'+value); }
     return (value);
}
function GenerateUnique() {
   var dt = new Date();
   var str = '';
   str      += (dt.getYear()-2000);
   str      += make2digit(dt.getMonth()+1);
   str      += make2digit(dt.getDay());
   str      += make2digit(dt.getHours());
   str      += make2digit(dt.getMinutes());
   return str;
}
alert (GenerateUnique());
</script>

slight modification to pravin's code:

str      += make2digit(dt.getDate());

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks raj3060 for pointing that out. Although i had corrected before your post.

To display the number on page

<html>
<body>
<script language="javascript">
function make2digit(value) {
     if (parseInt(value) < 10) { return ('0'+value); }
     return (value);
}
function GenerateUnique() {
   var dt = new Date();
   var str = '';
   str      += (dt.getYear()-2000);
   str      += make2digit(dt.getMonth()+1);
   str      += make2digit(dt.getDay());
   str      += make2digit(dt.getHours());
   str      += make2digit(dt.getMinutes());
   return str;
}
alert (GenerateUnique());
document.form1.unqfld.value = GenerateUnique();
document.getElementById('unqdiv').innerHTML = GenerateUnique();
</script>
</body>
<form name="form1">
<input type="text" name="unqfld" readonly value="">
</form>
<div id="unqdiv">UNIQUE NUMBER GOES HERE</div>
</html>

How about this:

<html>
<head>
<title>Zvonko &#42;</title>
<script>
function getUnique(theBtn){
  var theForm = theBtn.form;
  theForm.BPnr.value = (new Date()).getTime().toString().substr(3);
}
</script>
</head>
<body>
<form>
<input type="button" value="Generate" onClick="getUnique(this)">
<br>
<input type="text" name="BPnr" size="10" maxlength="10">
</form>
</body>
</html>

Or if the first digit should not be zero:

<html>
<head>
<title>Zvonko &#42;</title>
<script>
function getUnique(theBtn){
  var theForm = theBtn.form;
  theForm.BPnr.value = "7"+(new Date()).getTime().toString().substr(4);
}
</script>
</head>
<body>
<form>
<input type="button" value="Generate" onClick="getUnique(this)">
<br>
<input type="text" name="BPnr" size="10" maxlength="10">
</form>
</body>
</html>
