Multiple condition for phone number field in javascript

I have below code:
$('.mobileNumber').keyup(function () {
var mobile = $(this).val();
var numericExpression = /^[0-9]+$/;
if (mobile.length == 0 || mobile.length < 10 || !mobile.match(numericExpression)) {
$(this).parent().parent().parent().find('.jp-error-msg-kstm').css('display','block');
} else {
$(this).parent().parent().parent().find('.jp-error-msg-kstm').css('display','none');
}
});
what i'm trying to do is whenever my mobileNumber fields blank(ie. o length),less than 10 length and it should follow numbers only. if yes, then error message i.e. .jp-error-msg-kstm will appear else not.
for example, if i entered 1234567890 then it should not show me the error whereas if erase the value and make the field as 0 length or less than 10 then it should shoe the error span div.

Simply use .length.
if (mobile.length < 10 || !mobile.match(numericExpression)) {

I have used
mobile.length == 0
in the first if condition only.
So the code become
$('.mobileNumber').keyup(function () {
var mobile = $(this).val();
var numericExpression = /^[0-9]+$/;
if (mobile.length < 10 || !mobile.match(numericExpression)) {
if(mobile.length == 0){
$(this).parent().parent().parent().find('.jp-error-msg-kstm').css('display','none');
} else {
$(this).parent().parent().parent().find('.jp-error-msg-kstm').css('display','block');
}
} else {
$(this).parent().parent().parent().find('.jp-error-msg-kstm').css('display','none');
}
});

Error messages showing on next line

I have an error message that pops up at the top of my form when something is wrong but the errors stay on the same line. How do I make them go under each other or under the correct place on the web page? I have the below code on my html to display my error message at the moment. If needed I can show my html as well.
<p id="error"></p>

I have written this code on the fly .. to the editor here. but i am sure i have clear my point. any doubt post comment below.

I think the better code architecture would be as follows as it gives your more control keeping the sync with your exisiting design.
<ul id="error"></ul>

code does not validate email from a form, in javascpricpt

hi i font know if this is the right place to ask this question but i have a problem with my code that i cannot figure out. i have tried many different algorithms and none work. i am trying to validate email from a form.
here is the code (form is in html)
function isValidString(str) {
var quot = "\"";
if (str.indexOf(quot) != -1)
return false;
var badStr = "$%^&*()_+[]{}<>?אבגדהוזחטיכךלמםנןסעפצקרשת";
var i = 0,
p;
while (i < str.length) {
p = badStr.indexOf(str.charAt(i));
if (p != -1)
return false;
i++;
}
return true;
}
function isValidEmail()
{
var str = document.getElementById("email").value;
document.write("email from isValidEmail(str) = " + email);
if (isEmpty(str) || str.length < 5) {
alert("isEmpty(str) || str.length < 5 = false");
return false;
}
if (!isValidString(str)) {
alert("!isValidString(str) = false");
return false;
}
var atSign = str.indexOf('#');
if (atSign == -1 || str.lastIndexOf('#') || atSign === 0 || atSign == str.length - 1) {
alert("atSign == -1 || str.lastIndexOf('#') || atSign == 0 || atSign == str.length - 1 = false");
return false;
}
var dotSign = str.indexOf('.', atSign);
if (dotSign == -1 || dotSign === 0 || dotSign == str.length - 1 || dotSign - atSign < 2) {
alert("dotSign == -1 || dotSign == 0 || dotSign == str.length - 1 || dotSign - atSign < 2 = false");
return false;
}
return true;
no matter what i input it always comes back valid.
here is the part where i apply it:
var email = document.getElementById("email").value;
if (emailcheck(email)) {
alert("invalid email");
return false;
}
return true;
thanks in advance

An example of using the parser library mentioned in my comment.
var eAddr = document.getElementById('eAddr'),
check = document.getElementById('check'),
pre = document.getElementById('out');
check.addEventListener('click', function (evt) {
pre.textContent = !!emailAddresses.parseOneAddress(eAddr.value.trim());
}, false);
<script src="https://rawgit.com/FogCreek/email-addresses/master/lib/email-addresses.js"></script>
<input id="eAddr"></input>
<button id="check">Test pattern</button>
<pre id="out"></pre>
Note: this will accept Goodhertz Inc <support#goodhertz.com> as it stands and you would need to further check the object returned by parseOneAddress to filter these out.

You don't call the rigth function i. e. call
var email = document.getElementById("email").value;
if (isValidString(email)) {
alert("invalid email");
return false;
}
return true;
instead of
var email = document.getElementById("email").value;
if (emailcheck(email)) {
alert("invalid email");
return false;
}
return true;

Using Regular expression is the best method for validating input elements. Below function can validate email perfectly.
function regExValidate_Email(id) {
var email = document.getElementById(id).value;
if (email != '') {
var regExforEmail = /^[a-zA-Z0-9._+-]+#[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/;
if (regExforEmail.test(email)) {
$("#" + id).css("background-color", "#ffffff");
return true;
}
else {
alert('Please enter a valid email id. \nex: yourname#example.com');
document.getElementById(id).style.backgroundColor = '#feffea';
document.getElementById(id).value = '';
Ctrlid = id;
setTimeout("document.getElementById(Ctrlid).focus()", 1);
return false;
}
}
else { document.getElementById(id).style.backgroundColor = 'white'; }
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
Email: <input type="email" onblur="return regExValidate_Email(this.id)" id="txtEmail" />

How to I validate a password using regular expressions in javascript?

This is my code. It functions perfectly up to the password validation. It completely ignores my null test and goes straight to the actual validation but then refuses to go past it and keeps giving me my invalid password alert. Any ideas as to how to fix this issue?
function validate(){
var l = document.getElementById('lname').value;
var f = document.getElementById('fname').value;
var e = document.getElementById('email').value;
var e2 = document.getElementById('cemail').value;
var u = document.getElementById('newuser').value;
var p = document.getElementById('newpass');
var p2 = document.getElementById('cnewpass');
var str = new RegExp(/[a-zA-Z]{1,30}$/);
var em = new RegExp(/[a-z0-9._-]+#[a-z]+\.[a-z]{1,30}$/);
var pass = new RegExp(/[a-zA-Z0-9]{1,15}$/);
if (l == null || l == ""){
alert("Please enter your last name");
return false;
}
var ln = str.test(l);
if(ln==false){
alert("Invalid Name.");
documents.forms['registration']['lname'].focus;
return false;
}
if (f == null || f == ""){
alert("Please enter your first name");
return false;
}
var fn = str.test(f);
if(fn==false){
alert("Invalid Name.");
documents.forms['registration']['fname'].focus;
return false;
}
if (e == null || e == "") {
alert("Please enter an email address");
return false;
}
if (e2 == null || e2 == "") {
alert("Please enter an email address");
return false;
}
var eml = em.test(e);
if(eml==false){
alert("Invalid Email.");
documents.forms['registration']['email'].focus;
return false;
}
var eml2 = em.test(e2);
if(eml2==false){
alert("Invalid Email.");
documents.forms['registration']['cemail'].focus;
return false;
}
if(e2!=e){
alert("Please ensure that the emails match.");
return false;
}
if (u == null || u == "") {
alert("Please enter a user name");
return false;
}
var un = str.test(u);
if(un==false){
alert("Invalid user name");
documents.forms['registration']['newuser'].focus;
return false;
}
if (p == null || p == "") {
alert("works");
alert("Please enter a password");
return false;
}
if (p2 == null || p2 == "") {
alert("Please enter a password");
return false;
}
var pwrd = pass.test(p);
if(pwrd==false){
alert("Invalid Password.");
documents.forms['registration']['newpass'].focus;
return false;
}
if(p2!=p){
alert("Please ensure that the passwords match");
documents.forms['registration']['cnewpass'].focus;
return false;
}
}

You should amend js code that retriving data from from. Look,
var p = document.getElementById('newpass');
var p2 = document.getElementById('cnewpass');
Here You are trying to get NOT values of input tags, you are trying to get tag.
So You should replace above code with:
var p = document.getElementById('newpass').value;
var p2 = document.getElementById('cnewpass').value;
I hope it will help you

You should pass the value of password fields.
try changing the code to
var p = document.getElementById('newpass').value;
var p2 = document.getElementById('cnewpass').value;

Jquery form validation coding

My Jquery validation is not working, below is the script coding. I am getting a
Fatal error: Uncaught exception
error and not sure why. I know one of the reasons can be the validation code isnt correct. Is the coding correct or is there errors?
<script type="text/javascript">
$('form#contact').submit(function(e) {

You have php inside your JavaScript code:
