Let Email And Password Validation Work Together?
Nov 3, 2009
I have a form with an e-mail, password and confirm password field. I also have two Javascript scripts, one for the e-mail field and one for the password and confirm password field. They seem to work together. But when I fill in an invalid e-mail address and a valid password, Javascript forgets to check if the e-mail address is valid and sends the form.How can I let both Javascript scripts work better together? Or does someone know how to merge these two scripts?Below the whole code:
Code JavaScript:
// E-mail validation
function validate_required(field,alerttext)
[code]....

I have a URL that I intend to load into startup via a shortcut. I need
to have input of email address and password for it not to become a
pest at every startup.
When that is input manually I get a HTML which contains my DNS.
Incidentally that would be nice to have that displayed on the screen.
Both email and password come as
<td><img SRC="/homeparts/login_email.gif" WIDTH="67" HEIGHT="11"
BORDER="0" ALT="Email"></td>
The following line is the one that accepts the input as
<td><input TYPE="text" NAME="username" VALUE="" CLASS="login_box"
SIZE="25">
The question is: Can it be done. The problem is for an elderly chap
accustomed to C and C++ to be able to understand how. So some help
which will make C , Java or Javascript make it do that and possibly
pick off the DNS from the next screen.....

I have four pages.two html, one js and one php. First page is loginTab.html. There is a tab called "Tab One" when user clicks on it there is a script inside this html page which calls function and loads an external login.html form using ajax. in login.html there is a form and include external js code for ajax functions. What it does is when the user enters email and password and clicks submit then it triggers another ajax function which send a query to php file and compare those variables there with mysql db and returns the message to a div which is in login.html. The problem here is when I enter email and password and clicks on submit button it does not display anything. I am providing all of my code below
loginTab.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script>
window.onload = initAll;
var xhr = false; .....

I am using the jquery validation plugin to validate a form's email address field. The validation works but with the minor exception that when trailing whitespace is entered after the email the validation fails. I'm not sure if this is because of the regexp or a missing trim.

I need to validate a password to only allow A-Z, a-z and 0-9. I
thought this would work:
function Validate()
{
var passphrase = document.all.challenge.value;
var re = /[a-zA-Z0-9]/;
if (!re.test(passphrase))
{
alert("Please enter a valid password!");
return false;
}
else
{
return true;
}
}
however if the following is entered 045# - this is accepted a being
valid. What am i doing wrong?

I have a form with a password the user must enter. The password has no conditions, but there is a checkbox next to it. Users have an option to choose one of two checkboxes. If they choose the checkbox with the password then the password is required, the other checkbox does not require a password so the form would not need to validate the password in that instance.

I have a form which mostly works and validates with javascript Name, details, email, etc.
However the email bit is happy to validate with just @. instead of a@b.net/com/whatever.
It's probably a really simple fix, but I'm still new to javascript.. Hopefully someone can point out what I need to add / change in the following section of script.
if(form.email.value=="")
{
alert("Please Enter Email Address");
return false;
}
if(form.email.value!="")
{
str=form.email.value;
var AtTheRate= str.indexOf("@");
var DotSap= str.lastIndexOf(".");
if (AtTheRate==-1 || DotSap ==-1)
{
alert("Enter Proper Email Address");
return false;
}
else
{
if( AtTheRate > DotSap )
{
alert("Enter Valid Email Address");
return false;
} } }

Whoever allowed apostrophes to be valid within emails needs some talking to!
Anyway. I have just found out that this JS function I have been using and have no idea how it works does not allow emails with apostrophes in it. Does anyone know how to alter this code to allow apostrophes?
var pattern = new RegExp(/^(("[w-s]+")|([w-]+(?:.[w-]+)*)|("[w-s]+")([w-]+(?:.[w-]+)*))(@((?:[w-]+.)*w[w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$)|(@[?((25[0-5].|2[0-4][0-9].|1[0-9]{2}.|[0-9]{1,2}.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2}).){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})]?$)/i);

I've read enough about email validation to know that the only real validation is having a user respond to a confirmation message you've sent them. However, I want to store the address temporarily, so I want to make sure what is entered is safe to work with.
I have a basic understanding of regexps, so I could write one that checks for a simple
format like: something followed by @ followed by something followed by
.. followed by something. I can also make a good guess at understanding
the regexps I come across in validation schemes people have posted.
However, each scheme that is posted seems to get criticized for
invalidating some esoteric, but valid, addresses.
I'm wondering if there is a minimum validation you can do that will
prevent basic attacks like sql injection attacks. For example, if I
weed out anything with single and double quotes, and semicolons, am I
barring some people unnecessarily? Seems like you'd be trying to mess
with people by putting a semicolon in your email address.

I am a Javascript newbie and I'm trying to implement a very simple form validation function, but for some reason it won't work. I must be doing something fundamentally wrong here. Maybe somebody can hint me into the right direction? My code looks like so:
function validate_form ()
{
valid = true;
var re = new RegExp();
re.compile("[A-Za-z0-9._-]+@[^.]+..+");
if ((document.form.author_name.value == "")
|| (document.form.author_email.value == "")
|| (!re.test(document.form.author_email.value))
|| (document.form.author_message.value == ""))
{
alert ("Please fill in all required fields.");
valid = false;
}
return valid;
}
The tricky bit is the email validation using the regular expression. Apart from that it all works.

I am looking to add an email validation to my new user registration form. Currently, we do not validate (or activate) a new user via an activation link in the email. We don't have that process. I'd like to get my hands on the code to randonly create a security code and the actual code to sent the validation email. Can anyone help me out here? I'm absolutely new to PHP or ASP coding. I do know some HTML.
