Well, what you want to do is write a script that only allows legal characters, like "A-Z", "a-z", "0-9", "@", "+" "-", and others.

Why deos it say my email is not valid


You get many emails, especially if you run a business on the web. All of these emails are important because they are from your customers, friends or family. The ones from customers are even more important since they are usually orders for your products or questions about your business. Validate the email address before processing the order to make sure you can reach your customer.

Validate the email address by sending an email to the person who provided the email to you. If it bounces back to you, the email is not valid. Reach your customer through other contact information. Select the email address you want to validate at online validation site such as Broadband-help. Type in the email address or copy and paste it in the box on the page. Enter the validation code found on the page and click "Submit." Check results for the email address you entered in the "Results" box. You'll see a green arrow and the words "Valid email" for any valid email address. See the result for a non valid email as a red "X" in the results box. It will also say the words "Not valid email." Choose to validate a free email address at Ranks to find out if a free email address is valid. Enter the email address in the box and click on "Check." View results on the next page.

I'm online trying to register for a P/P Prem Account and I've filled in the first page of personal info...Name, Address, email & password etc. activate it at the bottom of the screen ... &...


I checked it right now, and you don't need to put a middle name.. These are the only things you need to input:

  • Email Address: Please enter a valid address in the format name@domain.com.
  • Password: Your password must contain between 8 and 20 characters. Please enter a longer password.
  • First Name: Please enter only letters, hyphens, spaces and commas.
  • Last Name: Please enter only letters, hyphens, spaces, and commas.
  • Address line 1: Please enter a valid Address line 1.
  • City: Please enter a valid City.
  • Home Telephone: Please enter a valid telephone number.
  • Date of Birth : Please enter your date of birth.
Hope this helped! =)

When I try to log on to my email, my id and password are accepted but the email pagee is blank.When I log on from another computer no problem.


One of the following reasons could be giving rise to your problem.Take suggested actions giv against each.

1. Your browser must be blocking the popups --> Disable popup blocker.
2. Your browser could be preventing java scripts from being run. --> Enable java script for this site in your browser settings.
3. The site being opened after login is perhaps blocked by your antivirus software --> Check the list of blocked addresses in your browser or antivirus.

The only reason I see is one of the above as the page is displayed when you login from another computer. The problem must be in settings of your browser or firewall/antivirus applications.

Validating in jsp


JavaScript Form Validation JavaScript can be used to validate input data in HTML forms before sending off the content to a server.
Form data that typically are checked by a JavaScript could be:
  • has the user left required fields empty?
  • has the user entered a valid e-mail address?
  • has the user entered a valid date?
  • has the user entered text in a numeric field?
Required Fields The function below checks if a required field has been left empty. If the required field is blank, an alert box alerts a message and the function returns false. If a value is entered, the function returns true (means that data is OK):
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
} The entire script, with the HTML form could look something like this:
<html>
<head>
<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{alert(alerttxt);return false;}
else {return true}
}
} function validate_form(thisform)
{
with (thisform)
{
if (validate_required(email,"Email must be filled out!")==false)
{email.focus();return false;}
}
}
</script>
</head> <body>
<form action="submitpage.htm"
onsubmit="return validate_form(this)"
method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body> </html>
E-mail Validation The function below checks if the content has the general syntax of an email.
This means that the input data must contain at least an @ sign and a dot (.). Also, the @ must not be the first character of the email address, and the last dot must at least be one character after the @ sign:
function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
} The entire script, with the HTML form could look something like this:
<html>
<head>
<script type="text/javascript">
function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
} function validate_form(thisform)
{
with (thisform)
{
if (validate_email(email,"Not a valid e-mail address!")==false)
{email.focus();return false;}
}
}
</script>
</head> <body>
<form action="submitpage.htm"
onsubmit="return validate_form(this);"
method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body> </html>

I cant send emails


If you have yahoo mail forwarding see: How do I verify my email address?

If you are getting error 533 , then see How to verify email addresses

If you use Outlook or Outlook express see:Why am I receiving an error when I send mail from Outlook

If instead ID/Password is not accepted read the following.
  1. Ensure that User ID and password are correct.
  2. Check if you have caps on, the password is case sensitive.
  3. Try using a different computer or a different browser (eg. downloadOpera Browser).
  4. Use Yahoo Password Recovery
  5. See also Yahoo! Password Helper
  6. If nothing worked, open a new account or contact Yahoo!
