JavaScript - Validate Email Address In Prompt Message Javascript
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.");
}
}
Code: <select id="lstBx" name="listBox" size="6" style="width: 580px;">
<option>a@hotmail.com</option>
<option>b@hotmail.com</option>
<option>c@yahoo.com</option>
<option>d@gmail.com</option>

I have this script to validate contact form fields. It works fine for checking that fields are not blank. I added the valid email code, which I copied from the w3schools web site. But, it does not work. I am confused about how to reference the email form field name. That is really the only thing I changed, that is, I added the frm.elements to the email variable. Can anyone please help? Thanks! Code: function validate_form(frm)
{
frm.elements.name.className = "input";
frm.elements.email.className = "input";
frm.elements.subject.className = "input";
frm.elements.comments.className = "input";
var errors=0;
//
// NAME cannot be blanks
//
if (isBlank(frm.elements.name.value)) {
frm.elements.name.className = "inputreq";
errors++;
}
//
// EMAIL ADDRESS cannot be blanks
//
if (isBlank(frm.elements.email.value)) {
frm.elements.email.className = "inputreq";
errors++;
}
//
// SUBJECT cannot be blanks
//
if (isBlank(frm.elements.subject.value)) {
frm.elements.subject.className = "inputreq";
errors++;
}
//
// COMMENTS cannot be blanks
//
if (isBlank(frm.elements.comments.value)) {
frm.elements.comments.className = "inputreq";
errors++;
}
//
// EMAIL ADDRESS appears invalid
//
if (validate_email(frm.elements.email.value,"Not a valid e-mail address!")==false) {
alert("TEST");
frm.elements.email.focus();
return false;
}
//
// Errors
//
if (errors>0) {
alert("Please enter all fields!");
return false;
}
//No errors
//frm.submit();
}
function isBlank(value)
{
regexp = /^\s*$/
return (value==null || regexp.test(value));
}
// Validate email address
function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
}
Hi, I want to check the email address type in a contact form but want to reject it if it's from a certain domain I actually use this regexp : /^[a-zA-Z0-9_\.\-]+\@([a-zA-Z0-9\-]+\.)+[a-zA-Z0-9]{2,4}$/ (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 there, I want to prompt a user to enter their name, if the user entry includes numbers I would like to prompt them to re-enter their name using only text. I have tried: Code: var userName = prompt ("Please enter your name", " ");
if (userName == null || !isNaN(userName)) {
prompt ("Please enter a valid name, and do not include any numbers in this field");
userNamm.focus();
} else {
document.write("Welcome back " +userName); }
It isn't working, I would like to monitor the user entry for only text values, can anyone help me to clean this up? Hi, 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.

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 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. I am trying to get these prompt boxes to display for age and resting heart rate. I cannot get this to work...This is what I have...any suggestions? <html> <head> <h1>Calculate Your Target Heart Rate</h1> <p>You can calculate your heart rate so that you can get the maximun results from your cardiovascular workout. Just follow these simple steps:</p> <script type="text/javascript"> function show_prompt() { var number = prompt ("Please enter your Resting heart rate:","Enter Rest Heart Rate Here!"); if (number! null && number! = "") var age = prompt ("Please enter your Age", "Enter Your Age Here!"); { document.write ("Your Resting Heart Rate is" + number); document.write ("Your Age is" + Age); } } </script> </head> <body> <input type ="button" onclick = "show_prompt ()" value = "Start Calculating Here!"/> </body> </html> I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers. I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign. Here's my js: function counter() { var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '\n' + "In the following format: -2,0,2"))); var positives = 0; var negatives = 0; var zeros = 0; for (var i = 0; i < numArr.length; i++) { switch (true) { case numArr[i] < 0: negatives++; break; case numArr[i] == 0: zeros++; break; case numArr[i] > 0: positives++; break; } } alert("You entered:"+ '\n' + "Number of Negatives: " + negatives + '\n' + "Number of Zeros: " + zeros + '\n' + "Number of Positives: " + positives); } counter(); Any suggestions? Issue: I have a java script that bring up a simple password box, It works great in Chrome, Safari, firefox but I get a box in Internet explorer asking my customers to take another step to allow access. This is not good, Customers did not now what to do. Error: This website is using a scripted window to ask you for information. If you trust this website, click here to allow scripted windows Microsoft response: "Internet Explorer has blocked a website from using a small program (called a script) to display a separate window. Hackers sometimes use scripted windows to mimic legitimate windows, such as login screens, that appear on websites. If you trust the website and want to allow the scripted window, click the Information Bar, and then click Temporarily Allow Scripted Windows. To always allow scripted windows, check the Allow websites to prompt for information using scripted windows custom security setting." Objective: I now there is likely no way to by pass this, so i need a different solution. Possible a Form Box to be present on the site that when information is entered it passes the password to the javascript code to allow access? Please help, this is actually urgent as I have already lost a customer :-( Code: : <script>
function getStyle()
{
var temp = document.getElementById("admintable").style.visibility;
return temp;
}
function switchMain()
{
var isAuthed = authenticate();
if(isAuthed){
var current = getStyle();
if( current == "visible" ){
document.getElementById("admintable").style.visibility = "hidden";
}else{
document.getElementById("admintable").style.visibility = "visible";
}
}
}
function authenticate()
{
if(readCookie('authenticated')!=null)
{
return true;
}
else{
var password=prompt("Enter Code","")
if (password =="1234")
{
createCookie('authenticated',true);
return true;
}
}
return false;
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
</script>
Here is what I found online: http://www.anyexample.com/webdev/jav...lternative.xml UPDATE: I am a n00b, I need to incorporate this code below to the one above. Thanx Philip Code: <input type = "password" name = "pwd" id = "pwd" onchange = checkPassword(this.value)"
<script type = "text/javascript">
function checkPassword(which) {
if (which != "1234") { // password is visible!!!
alert ("Incorrect password - please try again");
document.getElementById("pwd").value ="";
return false;
}
else {
alert ("Password is correct!");
//do more stuff here, e.g create the cookie
}
}
</script>
I'm slowly learning javascript, have a little java background. I wanted to just make a button you push to enter a prompt. The problem was I want the prompt message to print in a new window. Here is what I have. Can anyone help me with this? <html> <head> <script type="text/javascript"> function show_prompt() function openindex() { OpenWindow=window.open("", "newwin", "height=250, width=250,toolbar=no,scrollbars="+scroll+",menubar=no"); { var name=prompt("Please enter your name",""); if (name!=null && name!="") { OpenWindow.document.write("Hello " + name + "! How are you today? Welcome to my Demo page, Enjoy!"); } } } </script> </head> <body> <input type="button" onclick="show_prompt()" value="Click Me " /> </body> </html> 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 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. I know I'm missing something ever so small but maybe you guys can help... Thanks all <code> <script type="text/javascript"> function insertLink() { var lnk = prompt("Enter Link [http://www.url.com]"); var href = lnk.value; var lnkBuild = '<a href=" + href + "></a>' alert(lnkBuild); } } </script> </code> Hello Everyone, I'm new to JavaScript and I need some help, What I'm trying to do is type a background color for the content area of a table by using the prompt box.
