Making a function from onload event

[ldixon789@yahoo.co.uk]

I'm trying to convert an on load event into a function. I think this
should be really simple, but I'm new to Javascript. The following
works fine as the page loads

var favorite = GetCookie('Demo Name');

if (favorite > '1')
{
window.location .href = 'page2.htm';
}
else
{
alert('You must complete the lesson before proceeding');
}

I have tried to make it into a function by adding
function CookieRedirect( ) {
at the top and a closing } at the end, and calling it using a form
button in the body:
<INPUT TYPE="button" VALUE="Redirect " onClick="Cookie Redirect ()">-
but no luck.

Any help much appreciated, Laura

alert(2<09) // true [numerical compare]

alert('2'<'09') // false [ascii string compare]

Thanks very much that helped.

I have a related problem when setting the cookie. I only want to set
the cookie if the cookie value is less than a form field value. It
works fine up to number 9, but judges 10 as less than 2! I think it is
doing an ascii string compare rather than a numerical compare. The
code I'm using is:

function SetTheCookie()
{
var favourite2 = GetCookie('Page Number');
if(document.for ms[0].elements[0].value > favourite2)
{
var expdate = new Date ();
expdate.setTime (expdate.getTim e() + (24 * 60 * 60 * 1000 *
365));
SetCookie('Page Number', document.forms[0].elements[0].value,
expdate);
return false;
}
}

Thanks again,
Laura

A new question should have a new thread.
Give that tread a meaningful name, regarding the question

SetCookie(
and
GetCookie(

They are unknown javascript functions

Again you probably are comparing strings, which is only useful if you
want to sort a series of strings.

I hope to understand now the why of thre difference I wrote about in:

To convert a string to a number, you can but a unary + or 1* in front of
it.

myString = '0123'
myNumber = +myString // will contain the number 123

So how would you change the below code code?:

<form><input value='0009'></form>
<script ...
var JamesBond = '007'
if(document.for ms[0].elements[0].value > JamesBond ) alert("yes")
</ ...

Please do not try to write complex code. First check the individual
formulas in a temporary html, like I did in the above alerting example.
