document.form.fieldname.value=

[GeeItsBee]

I am sure this is relatively simple, but I am new to js and would appreciate some help in getting the following sorted.

I use the following in a hidden form field - onsubmit="stamp" which successfully inserts the dateandtime GMT date string into a pearl cgi template server-side.

function stamp() {
    document.myform.dateandtime.value = (new Date).toUTCString();
}
 

However, I needed a more precise method of date stamping the message and have constructed the ISO date script below which writes a descending number starting with the full year down to milliseconds e.g.

20071029081534876

var today = new Date()
  var month = today.getUTCMonth()+1
  var year = today.getUTCFullYear()
  var day = today.getUTCDate()
  var hour = today.getUTCHours()
  var minute = today.getUTCMinutes()
  var second = today.getUTCSeconds()
  var msec = today.getUTCMilliseconds()
 
  if(month<10) month = "0" + month
  if(day<10) day = "0" + day
  if(hour<10) hour = "0" + hour
  if(minute<10) minute = "0" + minute
  if(second<10) second = "0" + second
  if(msec<100) msec = "0" + msec
  if(msec<10) msec = "00" + msec
 
  var nowTime = (year + '' + month + '' + day + '' + hour + '' + minute + '' + second + '' + msec)
 
  document.write(nowTime);
 

My problem is; how do I use the DOM to get it to write as per my original script??

Any help appreciated

hi ...

welcome to TSDN ...

so i think you want the timestamp that you created to be the value of the hidden field like in your first example?

kind regards

Hi..

That's exactly what I want to do -

document.myform.dateandtime.value = ??

Many thanks

:) ok ... let me give you an example:

function get_time_stamp() {
    // your time-stamp-code here but instead of 
    // document.write it put the following:
 
    return nowTime;
}
 
function set_field_value() {
    node_ref.value = get_time_stamp();
}

kind regards

Many thanks.

I've had a play and couldn't get it to work, then I saw the 'light'!

function stamp() {
    document.myform.dateandtime.value = stampMe();
}
 
function stampMe() {
 
// my script in here   
 
  return nowTime;
}

I tried to make it harder than what it was!!
