I am learn Javascript, and I have been stuck on a assignment for weeks. Been asking for advice but it hasn’t been very helpful at all.
What I want to do is have two fields one for the name and the other for an email. The email has to be verified with all the characters of a email address. (@, .) I have made all this in my code. (I am stuck at this part.) When clicking a add button the name and email gets stored in an array. Another button you can search the array by characters and it writes out the name or email.
I hope someone can help me out here.
Here’s my code
Thanks

<html>
<head>
<script>
var array = new Array();
function submitForm()
{
var myForm = document.registrationForm;
var myRegExp = / .+@.+..{2,3}$/;
var characters = myRegExp;
var user_name = name;
var name = document.getElementById(“enterName”);
var user_email = email;
var email = document.getElementById(“enterEmail”);
var myUserName = myForm.user_name.value;
var myUserEmail = myForm.user_email.value;
//Both are fields blank
if (myUserName == “”)
{
myName = “<p style=color:red>Please enter your First name.</p>”;
name.innerHTML = myName;
return false;
}
else
{
myName = “”;
name.innerHTML = myName;
}
var invalidChars = ” /:,;”;
for (var k=0; k<invalidChars.length; k++)
{
var badChar = invalidChars.charAt(k);
if (myUserEmail.indexOf(badChar) > -1)
{
myEmail = “<p style=color:red>Only valid characters are letters, ampersand, hyphen, underscore, and period</p>”;
email.innerHTML = myEmail;
return false;
}
}
if (myUserEmail == “”)
{
myEmail = “<p style=color:red>Email must have at least 7 characters</p>”;
email.innerHTML = myEmail;
return false;
}
else

email.innerHTML = myName;
}
var periodPos = myUserEmail.indexOf(“.”,atPos);
if (periodPos+7 > myUserEmail.length)
