The simplest way to find out is to add alerts throught. That shows the
path the code is taking, and if you alert the values of things too,
it'll show you why. Example:

function getNextPage(){
var num = Math.random();
alert("in getNextPage, random num="+num);
if (num<.5) {
alert("in getNextPage, following<.5 logic")
location.href=" group1/group1-lab1.htm";
} else {
alert("in getNextPage, following else logic")
location.href=" group2/group2-lab1.htm";
}
}

Thanks Stevo, I have tried your code but still not clear why my code
isn't working!

After

alert("in getNextPage, following<.5 logic")

I just see the original email address input and not

group1/group1-lab1.htm

Where next?!

Cheers

I should have written that after seeing either

alert("in getNextPage, following<.5 logic")

or

alert("in getNextPage, following else logic")

I just get the original page back - no move to the new page?!

Stevo,

I seems that the

location.href=" group1/group1-lab1.htm";

or the

location.href=" group2group2lab 1.htm";

is wrong - but they seem Ok to me ...?

"location.h ref" is supposed to hold a _complete_ URL but your code
misses at least the protocol and host parts (i.e. "http://www.dom.tld/").
You might try using the "location.pathn ame" property which would accept
your value. However, that would not cause the browser to change to
that page.

Matthias,

I've tried the full URL (http:// etc) but no difference.

Odd thing is that I have another file which uses a different type of
check and that works OK - I cannot see the difference - this is it
below. can you see the difference which accounts for it working?

Cheers,

Geoff

function getNextPage(){
var num = Math.random();
if (num<.5) {
location.href=" group1/group1-lab1.htm";
} else {
location.href=" group2/group2-lab1.htm";
}
}

function CheckEmail(emai l) {

AtPos = email.indexOf(" @");
StopPos = email.lastIndex Of(".");

if (email == "") {
alert('Not a valid Email address');
}

if (AtPos == -1 || StopPos == -1) {
alert('Not a valid email address');
}

if (StopPos < AtPos) {
alert('Not a valid email address');
}

if (StopPos - AtPos == 1) {
alert('Not a valid email address"');
}

document.emailF orm.email_addre ss.focus();
document.emailF orm.email_addre ss.select();

if (email != "" && (AtPos != -1 || StopPos != -1) && StopPos AtPos
&& StopPos - AtPos != 1) {
parent.frame_to p.top_value = email;
getNextPage();
}

How do you define "no difference"? Just by (visual appearance)? Or did
you check the web-server logs to see whether there was a request
actually? Quite possibly the browser could have requested something
but failed (for whatever reasons) to update the display. But that's
just a wild guess.

Odd thing is that I have another file which uses a different type of
check and that works OK - I cannot see the difference - this is it
below. can you see the difference which accounts for it working?

Well, no. I'd recommend to create a test page _without_ frames (which
are an evil of the last century anyway) just to make sure, your
JavaScript code works at all. Only _after_ you've verified that each
snippet works as intended/expected include the code in your "real"
pages.

To check email addresses I'm using a simple RegEx:

var _reMail = /^\s*([\w\x2D\x2E]+\@([\w\x2D]+\x2E)+[A-Za-z]{2,5})/;

This is used by the onchange/onblur event method

function cbMail() {
if (! this.value) {
return; // nothing to do
} // if
var h = _reMail.exec(th is.value);
// required minimum: 12@4.67 or 1@34.67
this.value = ((h) && (h[1]) && (6 < h[1].length)) ? h[1] : '';
} // cbMail()

which I assign to the respective form field objects. In the form
object's submit handler then I've to check just whether there's a
value of not.

Perhaps browser caching is your problem, try the following:

if (num<.5) {
location.href=" group1/group1-lab1.htm?" + num;
} else {
location.href=" group2/group2-lab1.htm?" + num;
}

Please enter your email address <input type="text" name="email">

</form>

in case of a valid e-mail the flow goes to getNextPage

getNextPage sets location.href and exits without return value

onsubmit treats it as "OK to submit" and submits the form

action attribute if your form is not sets which defaults to
action="current URL" so the page gets reloaded

on page reload script gets reloaded as well so whatever location
change are made being lost

-------------------------------

make you getNextPage return false as well

Here's a clue?!

If I use FF I do not get the move to either of the 2 pages but if I
step through the script with Firebug it works!

Why?

Brilliant!

<form name="emailForm " onsubmit="valid ateEmail( this.email , 'Please
enter a valid email address');retur n false;">

The return false gets the next page - thanks for your analysis!

Try to replace type="submit" with type="button" and call validateEmail
in onclick event.
