Hi All,
I have this code. When I type in je***@ebay.com, it should run
alert("Thanks for your interest.") line. But it does not. Why and
how can I correct it? I use IE 6 with windows xp.
Thanks a lot.
<HTML><body>
<form name="myForm">
<INPUT TYPE="text" VALUE="Enter email" NAME="userEmail "
onChange=valida teInput()>
</form>
<script type="text/javascript">
this.myForm.use rEmail.select()
function validateInput() {
userInput = this.myForm.use rEmail.value
document.write( userInput)
if (userInput.inde xOf('@')>0 && userInput.index Of('.')>0)
alert("Thanks for your interest.")
else
alert("Please check that your email details are correct before
submitting")
}
</script> 13  1971

At this point, you've re-opened the current document and
written new HTML into it. Any previously existing HTML
or Javascript code in this page has been destroyed.
Any code that expects to interact with the previous HTML
or Javascript will fail.

There are more complete tests to verify an email address if you are
interested.
See:

But please don't use that one, as it rejects completely valid email
addresses.

It is *not* possible to verify an e-mail address -
<URL:http://www.merlyn.demo n.co.uk/js-valid.htm#VEmA> ;
indeed , thanks for the reminder, I have just changed the set of
addresses valid here, while not connected to the Internet.
One can only check that the format is compliant with the RFCs, which is
enough, in general, enough to show that an E-address has been attempted.

And allows invalid E-mail addresses. Her test says: " .@" is a valid
E-mail address.

I am looking for one that will exclude invalid characters too. Might
as well get as in as much validation as possible.

No, it's not worth the effort, the risk of losing a sale because you
reject a valid email address you don't understand isn't worth the
effort.
The cost of having lots of mi****@mouse.co m, or su*****@yourdom ain.com
etc is higher than having an email address - people don't type in
invalid email addresses unless they're also going to type invalid but
syntactically correct if forced to.

I think this is worrying too much about a situation that will never happen.
If someone goes to a web form to get information or buy a product and enters
an email address with nested comments, etc, then they're just being an ass.
In all my years of seeing forms submitted, I've never (that I can think of)
seen a valid email address from a person genuinely trying to submit the form
that wouldn't pass some simple validation tests.
I have seen my forms without any validation get submitted with values like
me@hotmail.co or me@hotmail.coom etc. Simple javascript validation would
prevent typos like that.
people don't type in
invalid email addresses unless they're also going to type invalid but
syntactically correct if forced to.
This is true. You can't prevent invalid but syntactically correct emails
from being submitted, and you shouldn't even think about trying :)

Hello All,
I have used MultipartRequest like the following to upload images.
MultipartRequest multi = new MultipartRequest(request,

It works fine.
But When a user accesses through Internet, this does not work.

Hi,
I have made an application in ASP.net with C#. The application works fine with localhost. I have uploaded the site.
I'm using web user controls in the form. but some of the button do not work when they are clicked. One thing that I have found that they are nested user controls. which do not work.
I'm unable to understand what is the problem with that.
thanks in advance.
