JavaScript - Email Address Validation Problem
Hi All,
I am trying to create a script for checking that checks that the email address entered into two input boxes is the same when a submit button is clicked, I have these two input boxes Code: <input type="text" name="user_email" id="user_email" /> <input type="text" name="user_email2" id="user_email2" /> This javascript code Code: <script type="text/javascript">
var email1 = document.getElementById(user_email);
var email2 = document.getElementById(user_email2);
function checkEmail(){
if (email1 != email2)
{
alert("The two email addresses are not the same");
}
}
</script>
and this code for the button Code: <input type="submit" name="submit" id="submit" onSubmit="checkEmail" /> However this code is not working, can anyone see where I am going wrong? Any help will be appreciated Thanks in advance Similar TutorialsHi, Im using the old nopcard scripts on my site. It does every thing right except it does not send a Email to my to my email adres. I dont know how to correct this because i dont know Javascript. I include the script if anybody know how to alter it so that it will send the info to my email adres as well.

errors++;
}
//
// EMAIL ADDRESS cannot be blanks
//
if (isBlank(frm.elements.email.value)) {

Hey All, Been having some trouble with this, I am trying to find a javascript or DHTML form field which is similar to the outlook web access email address fields which show an icon to identify the address, and the screen name of the address instead of the full email address, as a hyperlink. I was wanting to know if anyone knows of something like this already around or if I need to design my own. Thanks in advance. Hi, I want to check the email address type in a contact form but want to reject it if it's from a certain domain I actually use this regexp : /^[a-zA-Z0-9_\.\-]+\@([a-zA-Z0-9\-]+\.)+[a-zA-Z0-9]{2,4}$/ (taken from the jquery validationengine) to check if the email address is correctly formated but I'd like to reject it if contains hotmail between the @ and the . I tried many things but couldn't get something that works. If anyone has an idea, it would be greatly appreciated. Chag Hi everyone, this is my first post here and I hope that you can be of assistance!! I have an issue with a registration form. What I would like to do is only allow a certain email domain in the 'email' field. Eg. Only allowing @gmail.com email addresses, and all others would receive an error. This is the line of code that I believe needs changing: function isEmail(valor){if(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,4})+$/.test(valor)){return(true)}else{return false;}} I am not too familiar with this but through my hours of research, I believe that I need to add something to this line. Thanks in advance. EDIT: I SOLVED THIS BY USING "#" instead of "?". Thank you. Hello. My goal is to take a user's email from a form, store it in a cookie, and append it to the window location on the following page. I am doing this so that when a user shares the page with "add this widget" the stats will show me who shared the page. The problem I have is that window.location.replace("?"+ user_email); seems to be sending the browser in an infinite loop. Right now it is running as an inline function in the head. I tried calling the function with body onload and had the same problem. Code: <script = "Javascript">
(function readCookie() {
var user_email = unescape(document.cookie);
if (document.cookie)
{
window.location.replace("?"+user_email);
}
})();
</script>
Is there another way I could achieve the same result? Thank you, Jack Hi there, I would like to validate the email address typed into the prompt message by the user, but to no avail. Can some kind soul help? Code: function addOption()
{
var new = prompt("Enter New Item:");
if (!new == "")
{
var answer = confirm ("Are you sure you want to add? ")
if (answer)//if answer is true
{
var lst = document.getElementById('lstBx'); // listbox control id
// Now we need to create a new 'option' tag to add to MyListbox
for (var i = 0; i < lst.options.length; i++)
{
arrTexts = lst.options[i].text;
if (arrTexts.toLowerCase() == newItem.toLowerCase())
{
alert ("That email address is already included in the list - please enter another one.");
break;
}
else
{
validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
strEmail = lst.value;
// search email text for regular exp matches
if (strEmail.search(validRegExp) == -1)
{
alert('A valid e-mail address is required.\nPlease retry.');
return false;
}
var optionNew = document.createElement("option");
optionNew.value = new; // The value that this option will have
optionNew.innerHTML = new; // The displayed text inside of the <option> tags
// Finally, add the new option to the listbox
lst.appendChild(optionNew);
//sort items in listbox in alpha order
arrTexts = new Array();
for(i=0; i<lst.length; i++)
{
arrTexts[i] = lst.options[i].text;
}
arrTexts.sort();
for(i=0; i<lst.length; i++)

lst.options[i].text = arrTexts[i];
lst.options[i].value = arrTexts[i];
}
}
return false;
}
}
}
else

if(new == "")
{
alert("Key something to textbox please.");
}
else
alert("Cancelled.");

Hi Everyone! I have a text box ... but the label is in the textbox as the value so I use this code to make sure that something is filled in the field when a user clicks send: if(form.email.value == ('' || 'email*')){ alert('Please enter your email address'); return false; } <label><input type="text" name="email" id="email" class="required" value="email*" onfocus="if( this.value == 'email*') {this.value = '';}" onblur="if (this.value == '') { this.value = 'email*';}" /></label> I have tried to add email validation to the javascript code but I am failing! can someone help please? at the moment it just checks to see if the field has been filled out but doesn't check for the @ and .co.uk or .com. Many thanks! I've got a form validation script and I'm trying to add in a little extra oomph to what it checks. I'm not sure on the syntax for this, but I'm currently trying to make sure the email has the proper data using something like: else if (email.indexOf("@")<1 || email.indexOf(".")==-1 || email.indexOf(",")!=-1 || email.indexOf(" ")!=-1 || email.length<6) But when I add that if statement, the script does nothing, and they're taken to the next page. While I'm at it, is it possible to make sure that at least one of a series of looped-in dropdowns that have a php generated name: <select name="participantqty[<?= $c_row['workshop_id'] ?>]" id="" class=""> Here's the script I'm working from, with my if statement in it and breaking things: Code: <script type="text/javascript">
function required(){
var first = document.forms["register1"].elements["fname"].value;
var last = document.forms["register1"].elements["lname"].value;
var email = document.forms["register1"].elements["email"].value;
var message = document.forms["register1"].elements["phone"].value;
if(first == null || first == "" || last == null || last == ""){
alert("First and last name fields are required.");
return false;
}
else if(email == null || email == ""){
alert('An email address is required.');
return false;
}
else if (email.indexOf("@")<1 || email.indexOf(".")==-1 || email.indexOf(",")!=-1 || email.indexOf(" ")!=-1 || email.length<6)
{
alert('Please enter a valid E-mail address.\n" +
"Example: myname@domainname.com");
register1.email.focus();
return false;
}
else if(message == null || message == ""){
alert('A phone number is required.');

This piece of Dreamweaver(?) code appears to validate an email address: Code: function MM_validateForm() { //v4.0
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=MM_findObj(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }
} if (errors) alert('The following error(s) occurred:\n'+errors);
document.MM_returnValue = (errors == '');
}
The checking routine works well except I can't figure out how to invoke the email check part (red above?). This is the onsubmit bit: Code: <form id="quoteform" name="contactfrm" onsubmit="MM_validateForm('First_Name','','R','Last_Name','','R','City','','R','State','','R','Zip','','R','Day_Phone','','R','Evening_Phone','','','Email','','R');return document.MM_returnValue;" action="contact.php" method="post">
I have tried altering the field id and name below to "isEmail' but it does nothing: Code: <td height="32" bgcolor="#F8F8F8"><strong>Email Address:</td> <td><input name="YOUR EMAIL" type="text" id="Email" size="30"></td> Is it obvious? Let's start by saying that I stink at javascript. I've taken multiple different tutorials, some more than once, and I still can't get it. So, when I need a code, I search for it, and try different ones until I find something that works. I've been looking for a code for email validation for quite a long time, and I still can't find something that works with my code for validating the other parts of my contact form. I can get it to check for the presence of text, but not for the presence of an @ sign and period. I would like for someone to please help me figure this out. Right now I have the following code: Javascript Code: <!--
function validate_form ( )
{
valid = true;
if ( document.contact.firstnamecontact.value == "" )
{
alert ( "Please fill in the 'First Name' box." );
valid = false;
}
if ( document.contact.lastnamecontact.value == "" )
{
alert ( "Please fill in the 'Last Name' box." );
valid = false;
}
if ( document.contact.emailcontact.value == "" )
{
alert ( "Please fill in a valid email address." );
valid = false;
}
if ( document.contact.subjectcontact.value == "" )
{
alert ("Please fill in the 'Subject' box." );
valid = false;
}
if ( ( document.contact.topic[0].checked == false )
&& ( document.contact.topic[1].checked == false )
&& ( document.contact.topic[2].checked == false ) )
{
alert ( "Please choose your Topic of Inquiry" );
valid = false;
}
if ( document.contact.messagecontact.value == "" )
{
alert ( "Please specify a question/comment." );
valid = false;
}
return valid;
}
//-->
HTML Code: <form name="contact" method="post" action="contactcompletion.php3" onsubmit="return validate_form ( );"> <table> <tr> <td><b>First Name: </td><td><input type="text" name="firstnamecontact"/></td> </tr> <tr> <td><b>Last Name: </b></td><td><input type="text" name="lastnamecontact"/></td> </tr> <tr> <td><b>Email: </b></td><td><input type="text" name="emailcontact"/></td> </tr> <tr> <td><b>Subject: </b></td><td><input type="text" name="subjectcontact"/></td> </tr> </table> <br /> <br /> <h4>Topic of Inquiry (Choose One):</h4> <table> <tr> <td><input type="radio" name="topic" value="questionscontact" /><b> Questions</b></td> <td><input type="radio" name="topic" value="commentscontact" /><b> Comments</b></td> <td><input type="radio" name="topic" value="othercontact" /><b> Other</b></td> </tr> </table> <br /> <br /> <h4>Enter Your Questions or Comments:</h4> <br /> <textarea name="messagecontact" rows="10" cols="70"></textarea> <br /> <br /> <p><input type="submit" name="send" value="Send" /></p> Thanks a bunch in advance for helping me!! Hey, basically I have my assignment due in 2 and a half hours and I cannot work out how to validate a email address. What am I doing wrong? Been on the net for a couple of hours lurking to find some answers but now I am even more lost. Bit of information: Basically I need to work out how many tables are needed for a class room depending on the desktops and laptops used and how many roils of coils are needed blah blah blah. Then comes the tricky part (for me anyways) asking the user to confirm or cancel the order everything works up to confirming the quote and then validating the email address, canceling the confirm button works so I'm assuming it's just the validating that I have destroyed. Any help would be awesome, assignment is due very soon and no sections of code are helping me on the net. Code: function confirmquote()
{
var answer=confirm("Do you want to recieve a quote?");
if (answer==true)
{
var emailID=window.prompt("Please enter a VALID email address or type quit to exit");
}
else
{
alert("Quote has been rejected sir, please refreash to start order agian.");
}
}
}
function CheckEmail()
{
emailID = document.f1.Email.value
AtPos = emailID.indexOf("@")
StopPos = emailID.lastIndexOf(".")
Message = ""
if (emailID == "")
{
Message = "Not a valid Email address" + "\n"
}
if (AtPos == -1 || StopPos == -1) {
Message = "Not a valid email address"
}
if (StopPos < AtPos) {
Message = "Not a valid email address"
}
if (StopPos - AtPos == 1) {
Message = "Not a valid email address"
}
return Message
}
(ALL IN THE HEADER TAG) Code: var worknowplease = confirmquote(); var emailID=checkemail(); (Last few lines of code before [/body]) I have no idea what the validate email is trying to do in the coding, but I'm still very freash on JS. Thanks you for reading and if you can share any possible solutions to my problems. Thanks agian. This are my codes.. var add = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/; var email = form.txtEmail.value; if (add.test(email) = false) { alert("Please enter a valid email."); return false; } return true; } bt it wun work.. pls help.. I was hoping you could point out why the validation for the email in the script below keeps looping and how to fix it. Any pointers would be great. Thank you. Script is being used on a Static FBML page. Code: <script type="text/javascript">
function checkForm() {
var params=document.getElementById('myForm').serialize();
if(params.fullname==''){
displayerrormessage('Please Enter Your Full Name');
return false;
}
if(params.useremail==''){
displayerrormessage('Please Enter Your Email');
return false;
}
if(params.useremail!=''){
var emailfilter=/^w+[+.w-]*@([w-]+.)*w+[w-]*.([a-z]{2,4}|d+)$/i
var returnval=emailfilter.test(params.useremail);
if (returnval==false){
displayerrormessage('Please Enter Valid Email');
params.useremail.select();
}
return false;
}
if(params.userphone==''){
displayerrormessage('Please Enter Your Phone');
return false;
}
if(params.usercity==''){

Hello, When I have email validation and captcha in the same form, simply passing the captcha allows the form to be sent without an email address. When I remove the captcha, the form will not send without the email address. I want to have both. What am I missing? http://jaxpubliclibrary.org/lib/websiteform-test.html Code: <script>
function validateForm()
{
var x=document.forms["WebsiteQuestion"]["Email"].value;
var atpos=x.indexOf("@");
var dotpos=x.lastIndexOf(".");
if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length)
{
alert("Not a valid e-mail address");
return false;
}
}
function clearForms()
{
var i;
for (i = 0; (i < document.forms.length); i++) {
document.forms[i].reset();
}
}
</script>
Code: <div align="center"> <script language="javascript" src="http://www.captcha.cc/cap.js?cap_k=tocsoLPahVjmEHJZWtenaJEDoJXfrQaa" type="text/javascript"> </script> <input type=hidden name=cap_h id=cap_h value=""> <img border=1 id=cap_i src="http://www.captcha.cc/img.cgi?cap_k=tocsoLPahVjmEHJZWtenaJEDoJXfrQaa" align=middle><img align=middle style="margin-left: 4px;" id=cap_r onload="return cap_showReload(event);" src="http://www.captcha.cc/blank.png"><br> <input id=cap_t name=cap_t type=text value="" style="margin-top:4px;"> <input type=submit value="Submit Form" onclick="return cap_valid(event);"> </div> I appreciate any help. Thank you, Elbee I can't seem to get any Email validation to work, at all. no matter what different tactic I try. Right now I'm trying the most simplest of tactics.. Code: if((document.subscribe.contacttype.selectedIndex==1) && (document.subscribe.email.value=="")){
alert("Please enter a Valid Email Address.");
return false;
}
else{
if((document.subscribe.email.indexOf('@') < 0) || ((document.subscribe.email.charAt(email.length-4) != '.') && (document.subscribe.email.charAt(email.length-3) != '.')))
{alert("you have entered an invalid Email Address. Please try again.");
}
}
}
Any suggestions? my 'Email' feed is displayed after the 'drop-down selector' has been chosen, thus, the invoking of the if selectedIndex==1 && email.value="" return false;. Thanks for your assistance ahead of time. I am having trouble with my Contact Us form. For the validation for email, in function validateEmail in my javascript portion where if I include: Code:
else if (fld.value(".com")==-1 && entEmail.indexOf(".net")==-1 && entEmail.indexOf(".org")==-1 && entEmail.indexOf(".edu")==-1) {
window.alert("Please recheck your email address. it must in name@domain.xxx format.");
return false;
}
It skips the validation when I click the submit button and sends without validating the form. When I remove the code snippet above it validates fine but doesn't check for ".com", ."org", or ."net" which has to be included. I need to include a proper email address that includes "@" AND either one of these: ".com", ."org", or ."net" Anyone know of any ideas to solve this? Hello all, 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. Thanks
