Hello
I cannot see why this is not working - the idea being to check the
email address entered and if OK to move to either one of 2 pages - the
move does not happen.
The code below is in the lower of 2 frames.
Why?!
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 validateEmail ( emailField, errorMsg ) {
emailpat =
/^([a-zA-Z0-9])+([\.a-zA-Z0-9_-])*@([a-zA-Z0-9])+(\.[a-zA-Z0-9_-]+)+$/;
if( !emailpat.test( emailField.value ) ) {
alert( errorMsg);
emailField.focus();
emailField.select();
return false;
} else {
getNextPage();
}
}

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="group2group2lab1.htm";
is wrong - but they seem Ok to me ...?

"location.href" 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.pathname" 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?

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

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(this.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:

location.href="group1/group1-lab1.htm?" + num;
} else {
location.href="group2/group2-lab1.htm?" + num;

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?
