Creating a JavaScript error message.

[RobPolley]

I'm every so slowly learning xbasic. It's a fun challenge. This code works:

function CanInsertRecord as v (DataSubmitted as P, Args as p, PageVariables as p, Result as p)
with PageVariables
if DataSubmitted.Email1<>DataSubmitted.Email2 then
Result.Cancel = .t.
Result.ErrorHTML = "Email addresses must match. Please try again."
else result.cancel = .f.
end if
end with
end function

...but I wanted to have a nice Javascript error message rather than the built in exclamation point. After Result.Cancel=.t. I tried:

"Alert('Email addresses must match.');"

...but nothing happens.

May I ask for help?

Thank you.

Re: Creating a JavaScript error message.

Since you do not have access to the e object here, why don't you do this in javascript on the OnBlur of the second email address?
Here is javascript that would do this:

var email1 = {grid.Object}.getValue('G','EMAIL_ADDRESS_1',-1);
var email2 = {grid.Object}.getValue('G','EMAIL_ADDRESS_2',-1);
if (email1!=email2)
{
alert('Email addresses must match!');
}

Let us know how this works out for you.

So what if I change email_address_1 after both email_address_1 and email_address_2 are filled in?

Re: Creating a JavaScript error message.

Al, I think you know the answer to that.
But if you are testing me, here is the answer in pseudo-code.
As you leave field one, check for the length of field two. If it is more than 1 character long (or zero or 3), check if both email addresses agree. If not, flag them.

Al,

...then this solution won't work. Knowing your expertise, I am guessing that you know this and were pointing it out to me. I'm fortunate that this is a low risk application - step one in replacing a manual system, so this "design flaw" won't be a problem.

All that said, I'm interested in hearing your thoughts on a solution that would handle the situation you described.

Thank you.

Rob,
See above.
Javascript lenth command is
email1.length

Hope this helps.

Jay's got you going in the right direction. I didn't want you to overlook what a user can do that is unintended.

While your system may be tolerant, others that see this might need a really tight system.....

Al,

Knowing the sincerity of your contributions on this forum, I was already assuming your motives were along these lines.

Many thanks!
