assigning values

[Jes]

Hi

I have a problem with assigning values in a form. I have a date field
in MySql and when I load the form , I would like to spilt it up in 3
fields ie day, month and year. I created 3 fields in the form ie.

<td class="Input"><input name="BKYEAR" size=8 id="BKYEAR">
<td class="Input"><select name="BKMONTH" size=8 id="BKMONTH">
<td class="Input"><select name="BKDAY" size=8 id="BKDAY">

On loading the form I would like to create a function that reads the
date field and spilt them to these fields so that each filed display
the values correctly from the date.

function readdate() {
var today = new Date();
today = document.getElementById("txtBookingsBOOKINGDATE").value;
alert(today)
BKDAY = today.getDate();
}

On the last line , I am getting an the following error:
'Object doesn't support this property or method'

Why ?

Thanks
Jesmond

"ie"?

<td class="Input"><input name="BKYEAR" size=8 id="BKYEAR">
<td class="Input"><select name="BKMONTH" size=8 id="BKMONTH">
<td class="Input"><select name="BKDAY" size=8 id="BKDAY">

That's really a very bad idea because it will work only with client-side
script support. You have MySQL available, so most certainly you have a
server-side application available, e.g. PHP. Let that generate the form
with the fields instead.

function readdate() {
var today = new Date();
today = document.getElementById("txtBookingsBOOKINGDATE").value;
alert(today)
window.alert(today);

BKDAY = today.getDate();
}

'Object doesn't support this property or method'

Why ?

Fantasy syntax; a String object is not a Date object, and your DOM approach
is IE-proprietary. RTFM.

There is no type information associated with a javascript identifier
itself, but the type information is with the content of the variable.

function readdate() {
var today = new Date();

That sets today to a Date Object representing the current instant.

today = document.getElementById("txtBookingsBOOKINGDATE").value;

That sets today to a String given by a control, abandoning the Date
Object. You may think it looks like a Date; Javascript does not (yet).

alert(today)

That should show the String.

BKDAY = today.getDate();

A String has no getDate property.

}

On the last line , I am getting an the following error:
'Object doesn't support this property or method'

That is proper.

You could use
var St = document.getElementById("txtBookingsBOOKINGDATE").value
var today = new Date(St)
but I don't guarantee that the second statement will like the
unspecified format of St.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.
