Email Validation using setCustomValidity

I got the following code for
// Validating Email
function validateEmail() {
var mail = document.getElementById("email").value;
var mailformat = /^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{3})+$/;
var endEmail = "#gmail"
if(mail.match(mailformat) && (mail.charAt(x.length-1) == endEmail) ) {
mail.value += ".com"
alert(mail)
return true;
} else if (email.validity.valueMissing) {
console.log("Email is missing")
email.setCustomValidity("Please fill in the email.");
}
}
I have a problem with checking the email. The logic I am trying to implement is to check whether the email contains “gmail” after “#” and to validate the email ends in “.com” (This check is only mandatory if the email field has “gmail” after “#”.). In the case of gmail being in the email after “#” and the ending being something other than “.com”, I wanna fix this for the user and let the submission go through after the fix.

validating reCaptcha in javascript function that get called on submit. (ASP classic)

I need help in validating the response of ReCaptcha in javascript validation which is made for other validations like, n Field is empty etc..
The javascript function function verify(f) {....} get called on onSubmit="return verify(this);" in html <form name="form2" method="POST" action="alink.asp" onSubmit="return verify(this);">
Bellow is the complete js function:
function verify(f) {
var msg = '';
var s = f.CKRoutingNumber.value;
s = s.replace(/[^0-9]/gi, "");
f.CKRoutingNumber.value = s;
if (f.CustomerID.value == '') { msg = 'Please enter your Bricks R Us Customer ID.'; f.CustomerID.focus(); }
else if (f.PurchaseOrderNumber.value == '') { msg = 'Please enter the purchase order number.'; f.PurchaseOrderNumber.focus(); }
else if (f.Amount.value == '') { msg = 'Please enter the amount you wish to pay.'; f.Amount.focus(); }
else if (f.CKBankName.value == '') { msg = 'Please enter a value into the Bank Name field.'; f.CKBankName.focus(); }
else if (f.CKRoutingNumber.value == '') { msg = 'Please enter a value into the Routing Number field.'; f.CKRoutingNumber.focus(); }
else if (s.length != 9) { msg = 'Please enter a valid nine-digit routing/transit number.'; f.CKRoutingNumber.focus(); }
else if (f.CKAccountNumber.value == '') { msg = 'Please enter a value into the Account Number field.'; f.CKAccountNumber.focus(); }
else if (f.CKNumber.value == '') { msg = 'Please enter a value into the Check Number field.'; f.CKNumber.focus(); }
else if (f.BillingName.value == '') { msg = 'Please enter a value into the Full Name field.'; f.BillingName.focus(); }
else if (f.BillingAddress.value == '') { msg = 'Please enter a value into the Billing Address field.'; f.BillingAddress.focus(); }
else if (f.BillingCity.value == '') { msg = 'Please enter a value into the Billing City field.'; f.BillingCity.focus(); }
else if (f.BillingState.value == '') { msg = 'Please select a value for the Billing State field.'; f.BillingState.focus(); }
else if (f.BillingZIPCode.value == '') { msg = 'Please enter a value into the Billing ZIP Code field.'; f.BillingZIPCode.focus(); }
else if (f.BillingPhone.value == '') { msg = 'Please enter a value into the Phone Number field.'; f.BillingPhone.focus(); }
if (msg != '') {
alert(msg);
return false;
}
}
The above function is on the same page in which the form is made.
Bellow is the ASP classic code which get response from reCaptcha. Its also on the same page
<%
Dim reresponse
reresponse= Request.form("g-recaptcha-response")
Dim VarString
VarString = _
"?secret=6Lex3CMTAAAAAASVS5XnIq4Ya5ZGvEH_W70NU&" & _
"&response=" & reresponse & _
"&&remoteip=" & Request.ServerVariables("REMOTE_ADDR")
Dim url
url="https://www.google.com/recaptcha/api/siteverify" & VarString
Dim objXmlHttp
Set objXmlHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")
objXmlHttp.open "POST", url, False
objXmlHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objXmlHttp.send
Dim ResponseString
ResponseString = objXmlHttp.responseText
Set objXmlHttp = Nothing
If instr(ResponseString, "success" & chr(34) &": true")>0 then
// do nothing
else
// Here I want to get this response message and validate it in the above javascript function.
end if
%>
I'm confused that how can I get the response from asp and validate it in the verify(f) javascript function so that I also get alert message on submit button that the recaptcha is required and or incorrect.
My intention is to validate the reCaptcha response in same veryify javascript function which get called on submit and shows validation in alert()
Remember, both asp code and javascript code are in the same page.
Please ask if you also need my form html code

Your verify() function is running locally and doing some input value checking/alerting is OK, but in any case you should check whatever comes from the browser on de server side. If you would send the ReCaptscha response back to that verify() function you undermine your security because your users could simple change that verify() function ...

Javascript Validation

I am wanting to make validation to my Email form. Unfortunately I cannot get this piece of code to work. When I am clicking submit without entering any data in to the form it will send.
I am wanting it not to send without the right Characters in the Email
I have attached a screenshot below of my code

You need to change your regex as:
var email_regex = /^[\w%_\-.\d]+#[\w.\-]+.[A-Za-z]{2,6}$/; // reg ex email check
if(emailAddress == "")
{
// error if empty
}
else
{
if(!email_regex.test(emailAddress))
{
// invalid error
}
else
{
// success
}
}

JavaScript not giving alert on invalid Confirm Password text

For proper registration, user is required to enter password two times and password in both these textboxes should match.
However, on validating this using this code, JavaScript is not showing alert dialog.
Here pswrd and pswrd1 are two textboxes of password type.
var message="";
var result=false;
if(pswrd.value!== pswrd1.value)
{
message+="\nPasswords did not match";
result=false;
}
if(!result)
{
alert(message);
}

Try this
var message="";
var result=false;
if(pswrd.value!== pswrd1.value)
{
message = "Passwords did not match";
result=false;
}
else {
result = true;
}
if(!result)
{
alert(message);
}

Try this code.
if(pswrd.value!== pswrd1.value)
{
alert("Password does not matched!");
return false;
}
Hope this help :)

if(pswrd.value !== pswrd1.value)
the text in bold above should be != and not !==
!== is not an operator, use == for equality and != for unequality

Why won't JavaScript alert box work in this example?

I am trying to validate 3 fields in a html form using javascript. If any of the fields are empty an alert box appears with a message indicating which fields are empty. This all works fine. I'm having a problem getting the message (msg2) to appear in an alert box when the form has been completed properly. My code is below-I know it's just something simple that I'm missing if anyone can help. Thanks!
var valid = true;
var msg="Incomplete form:\n";
var msg2="Success! There are no null fields.";
if ( myname== "" ) {
msg+="You need to fill the name field!\n";
valid = false;
}
if ( emailaddress == "" ) {
msg+="You need to fill in your email!\n";
valid = false;
}
if ( commentString == "" ) {
msg+="You need to fill in your comment!\n";
valid = false;
}
if ((!myname=="")&&(!emailaddress=="")&&(!commentString=="")){
return msg2;
}
if (!valid) alert(msg);
return valid;
}

You're right, it's something simple: return msg2; will not open an alert box. You still have to call alert() somewhere.

i think a little change in your code will solve the problem:
if (!valid) alert(msg);
return valid;
}
change it to
if (!valid) {
alert(msg);
return valid;
}

if (!valid) {
alert(msg);
} else {
alert(msg2);
}
return valid
Maybe somethign like that? And remove the block with if ((!myname=="")&& ...
