InnerHTML in multiple fiields and more than one error statements

I am having trouble trying to get the form to validate using the onblur handler.
What I am trying to do is to get the first and last name field to display an error message if the field is blank, if it’s less than 5 , more than 18 characters, or it the user enters a number.
I would like to be able to do this using only one function so I do not need to do this for seperate functions.
Eg:
function ValidateName(field) {
var field = field.value;
var output = document.getElementById("fnameError");
if (field == "")
{
output = "field can’t be blank.";
return false;
}
else
{
output = "";
}
}
<form>
<input type="Text" id="Fname" onblur="ValidateName(this)">
<span id="fnameError"></span>
</form>

Your answer according to the question.
function ValidateName(field) {
var output = document.getElementById("fnameError");
if (field.value == "")
{
output.innerHTML = "field can’t be blank.";
}
else
{
output.innerHTML = "";
}
}
<form>
<input type="Text" id="Fname" onblur="ValidateName(this)">
<span id="fnameError"></span>
</form>
Your answer according to the the comment made on my answer.
function ValidateName() {
var outputF = document.getElementById("fnameError");
var outputL = document.getElementById("lnameError");
var outputB = document.getElementById("BothError");
var field1 = document.getElementById("Fname");
var field2 = document.getElementById("Lname");
if (field1.value == "" && field2.value == "")
{
outputF.innerHTML = "";
outputB.innerHTML = "No field can be left blank.";
outputL.innerHTML = "";
}
else if (field1.value !== "" && field2.value == "")
{
outputF.innerHTML = "";
outputB.innerHTML = "";
outputL.innerHTML = "field can’t be blank.";
}
else if (field1.value == "" && field2.value !== "")
{
outputF.innerHTML = "field can’t be blank.";
outputB.innerHTML = "";
outputL.innerHTML = "";
}
else {
outputF.innerHTML = "";
outputB.innerHTML = "";
outputL.innerHTML = "";
}
}
<form>
<input type="Text" id="Fname" onblur="ValidateName()">
<span id="fnameError"></span>
<br><br>
<input type="Text" id="Lname" onblur="ValidateName()">
<span id="lnameError"></span>
<br><br>
<span id="BothError"></span>
</form>

you can try this also
function validateform(){
var name=document.myform.name.value;
if (name==null || name==""){
alert("Name can't be blank");
return false;
}
else if(name.length < 5){
alert("name must be atleast 8 characters long");
return false;
}
else if(name.length <18){
alert("text must be more than 18 characters");
return false;
}
}
<form name="myform" method="post" action="" onsubmit="return validateform()" >
Name: <input type="text" name="name"><br/>
<input type="submit" value="register">
</form>

Clearing validation errors JavaScript

I have been attempting to clear messages once the user has successfully input completed the required validation rules, however I can't seem to clear all the validation errors, I did look around and tried what was suggested however it doesn't seem to have worked. I thought by placing empty innerHTML strings might work as I said it had been suggested within other posts
<form action ="" method="POST">
<span id="tryErr"></span><br>
<input type="text" id="username" placeholder="Username"><br>
<span id="usernameErr"></span><br>
<input type="text" id="email" placeholder="Email address"><br>
<span id="emailErr"></span><br>
<input type="password" id="password" placeholder="Password"><br>
<span id="passwordErr"></span><br>
<input type="submit" value="Submit" onclick=" return confirmValidation();">
</form>
JS
<script type="text/javascript">
function validateUsername(username, error){
var username = document.getElementById("username").value,
error = document.getElementById("usernameErr");
if(username == null || username==""){
return error.innerHTML = "Username is required";
return false;
}
else if(!username.match(/^[0-9a-z]+$/) || username.length < 3){
return error.innerHTML = "Username must be alphanumeric and three characters long";
return false;
}
else{
return error.innerHTML = "";
return true;
}
}
function validatePassword(password, error){
var password = document.getElementById("password").value,
error = document.getElementById("passwordErr");
if(password == null || password==""){
return error.innerHTML = "Password is required";
return false;
}
else if(password.length < 7){
return error.innerHTML = "Password must be seven characters long";
return false;
}
else{
return error.innerHTML = "";
return true;
}
}
function validateEmail(email, error){
var email = document.getElementById("email").value,
apos = email.indexOf("#"),
dotpos = email.lastIndexOf("."),
error = document.getElementById("emailErr");
if(email == null || email==""){
return error.innerHTML = "Email is required";
return false;
}
if (apos < 1 || dotpos-apos < 2 || dotpos == (email.length - 1)){
return error.innerHTML = "Please enter a valid email";
return false;
}
else{
return error.innerHTML = "";
return true;
}
}
function confirmValidation(e){
event.preventDefault(e);
if(!validateUsername()){
return false;
}
if(!validatePassword()){
return false;
}
if(!validateEmail()){
return false;
}
else{
//do something clever here
}
}
</script>

You should use onchange event on input types .
Like
<input type="text" id="username" placeholder="Username " onchange="validateUsername()">

Javascript Form Validation Not Successful

Practicing my Javascript on a simple HTML form. Enter password in one box, enter again to confirm in the second. Password should contain 6 character (including 1 number), and no spaces. An alert message should pop up if the passwords meet the criteria and match.
I have it mostly there, in that the error messages pop up if the criteria aren't met, but I can't get to alert "Success!" I've toyed with the if statements so many ways, I'm not sure what I'm missing. Any suggestions?
Javascript:
window.onload = function() {
document.getElementById('submit').addEventListener('click', validateInput);
}
var userPass = document.getElementById('password').value;
var confirmPass = document.getElementById('confirm_password').value;
function validatePassword() {
var userPass = document.getElementById('password').value;
if (userPass.length == 0) { // Nothing was entered
document.getElementById('password_error').innerHTML = 'Please enter a password';
} else if (userPass.length < 6) { // Less than 6 chars
document.getElementById('password_error').innerHTML = 'Your password must be at least 6 characters in length';
} else if (userPass.match(/\s/)) { // contains a space
document.getElementById('password_error').innerHTML = 'Your password cannot contain spaces';
} else if (!userPass.match(/\d/)) { // Does not contain a number
document.getElementById('password_error').innerHTML = 'Your password must contain a number';
} else if (userPass !== confirmPass) {
document.getElementById('confirm_error').innerHTML = 'Passwords do not match. Please check again.';
} else {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = "";
alert("Success!");
clearFields();
}
}
function validateConfirm() {
function clearFields (){
document.getElementById('password').value=null;
document.getElementById('confirm_password').value=null;
}
if (confirmPass.length == 0) {
document.getElementById('confirm_error').innerHTML = "Please confirm password to proceed";
} else if (confirmPass.length < 6) {
document.getElementById('confirm_error').innerHTML = "Your password must be at least 6 characters in length";
} else if (userPass !== confirmPass) {
document.getElementById('confirm_error').innerHTML = 'Passwords do not match. Please check again.';
} else {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = "";
alert("Success!");
clearFields();
}
}
function validateInput() {
validatePassword();
validateConfirm();
}
The form:
<form>
<fieldset>
<legend>CONFIRM PASSWORD</legend>
<label for="name">Password: </label>
<input type="text" id="password" size="10" />
<p id="password_error" class="error"></p>
<label for="name">Confirm Password: </label>
<input type="text" id="confirm_password" size="10" />
<p id="confirm_error" class="error"></p>
<button id="submit">Submit</button>
</fieldset>
</form>

I've found two fault in your code
Set clearFields() function outside function validatePassword();
var confirmPass enter inside function or pass from calling function
window.onload = function () {
document.getElementById('submit').addEventListener('click', validateInput);
}
function validatePassword() {
var userPass = document.getElementById('password').value;
var confirmPass = document.getElementById('confirm_password').value;
if (userPass.length == 0) { // Nothing was entered
document.getElementById('password_error').innerHTML = 'Please enter a password';
} else if (userPass.length < 6) { // Less than 6 chars
document.getElementById('password_error').innerHTML = 'Your password must be at least 6 characters in length';
} else if (userPass.match(/\s/)) { // contains a space
document.getElementById('password_error').innerHTML = 'Your password cannot contain spaces';
} else if (!userPass.match(/\d/)) { // Does not contain a number
document.getElementById('password_error').innerHTML = 'Your password must contain a number';
} else if (userPass !== confirmPass) {
document.getElementById('confirm_error').innerHTML = 'Passwords do not match. Please check again.';
} else {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = "";
alert("Success!");
clearFields();
}
}
function clearFields() {
document.getElementById('password').value = null;
document.getElementById('confirm_password').value = null;
}
function validateConfirm() {
var userPass = document.getElementById('password').value;
var confirmPass = document.getElementById('confirm_password').value;
if (confirmPass.length == 0) {
document.getElementById('confirm_error').innerHTML = "Please confirm password to proceed";
} else if (confirmPass.length < 6) {
document.getElementById('confirm_error').innerHTML = "Your password must be at least 6 characters in length";
} else if (userPass !== confirmPass) {
document.getElementById('confirm_error').innerHTML = 'Passwords do not match. Please check again.';
} else {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = "";
alert("Success!");
clearFields();
}
}
function validateInput() {
validatePassword();
validateConfirm();
}
<form>
<fieldset>
<legend>CONFIRM PASSWORD</legend>
<label for="name">Password: </label>
<input type="text" id="password" size="10" />
<p id="password_error" class="error"></p>

<input type="text" id="confirm_password" size="10" />
<p id="confirm_error" class="error"></p>
<button id="submit">Submit</button>
</fieldset>
</form>

There are multiple issues
The function clearFields() is available only inside validateConfirm
You are reading the value of the confirm input only once at the page load, you need to read the new value within the validate method else it will always be empty string
Since you are validating the policy in the password field, not need to check it again for the confirm field since you are checking whether the confirm and password fields are the same
window.onload = function() {
document.getElementById('submit').addEventListener('click', validateInput);
}
function validatePassword() {
var userPass = document.getElementById('password').value;
var confirmPass = document.getElementById('confirm_password').value;
if (userPass.length == 0) { // Nothing was entered
document.getElementById('password_error').innerHTML = 'Please enter a password';
} else if (userPass.length < 6) { // Less than 6 chars
document.getElementById('password_error').innerHTML = 'Your password must be at least 6 characters in length';
} else if (userPass.match(/\s/)) { // contains a space
document.getElementById('password_error').innerHTML = 'Your password cannot contain spaces';
} else if (!userPass.match(/\d/)) { // Does not contain a number
document.getElementById('password_error').innerHTML = 'Your password must contain a number';
} else if (userPass !== confirmPass) {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = 'Passwords do not match. Please check again.';
} else {
document.getElementById('password_error').innerHTML = "";
document.getElementById('confirm_error').innerHTML = "";
alert("Success!");
clearFields();
return true;
}
return false;
}
function clearFields() {
document.getElementById('password').value = '';
document.getElementById('confirm_password').value = '';
}
function validateInput() {
return validatePassword();
}

I have created registration form and create validation in JavaScript for input fields.
onBlur validation is done, and works fine.
But when I click on the 'Sign Me Up' button, validation is not done and data is inserted into the database. Please I need help.

submit events fire on forms, not submit buttons. Move the onsubmit attribute to the <form> start tag.

"emailID.focus(); " is wrong is in ValidateEmail() function. instead of it
"email.focus(); is right.
Now it works fine as i expected.
but there is no need of this so i removed it.

Help, I am trying to validate my form. It can validate all fields, but not submitting after validated. I tried to run the codes in http://jsfiddle.net/CrLsR/297/ but after validated the form, it can't proceed to the test.html page. I'm new in javascript so, I can't figure out what is the probleml. Any help will very much appreciated. thanks..

As your inner validation methods return true or false, you need to modify your parent validation method to this or similar.
function validateForm(regForm) {
var formValid = true;
formValid &= validatefName(regForm.firstname);
formValid &= validateUsername(regForm.username);
formValid &= validatePassword(regForm.password);
formValid &= validatePassword2(regForm.password2);
formValid &= validateEmail(regForm.email);
if (!formValid) {
return false;
}
return true;
}

Try changing this line
var warning = "";
warning += validatefName(regForm.firstname);
warning += validateUsername(regForm.username);
warning += validatePassword(regForm.password);
warning += validatePassword2(regForm.password2);
warning += validateEmail(regForm.email);
if (warning != "") {
To this line
if(validatefName(regForm.firstname) == true && validateUsername(regForm.username) == true && validatePassword(regForm.password) == true && validatePassword2(regForm.password2) == true && validateEmail(regForm.email) == true) {
and see if it is correct now

Based on your fiddle, I found some errors in your code in the condition
if (title=="" || title==null) { } else {
alert("Please enter only alphanumeric values for your advertisement title");
}
Should be
if (title.length != 0) { } else {
alert("Please enter only alphanumeric values for your advertisement title");
return false;
}
The second is a more effective way to check if a field has no value.
I've also added return false in your else condition and the last return should be true.
here is your validateForm function. I updated your fiddle here
function validateForm() {
// Validate Email
var email = $("#fremail").val();
if ((/(.+)#(.+){2,}\.(.+){2,}/.test(email)) || email.length != 0) {
} else {
alert("Please enter a valid email");
return false;
}
// Validate Title
var title = $("#frtitle").val();
if (title.length != 0) {} else {
alert("Please enter only alphanumeric values for your advertisement title");
return false;
}
// Validate URL
var url = $("#frurl").val();
if (validateURL(url)) {} else {
alert("Please enter a valid URL, remember including http://");
return false;
}
return true;
}

Set a Flag = 1 in the function validateForm()
Increment Flag, if have validation error
End, return true, if Flag == 1 which means no error
function validateForm()
{
var flag = 1;
// Validate URL
var url = $("#frurl").val();
if (validateURL(url)) { } else {
alert("Please enter a valid URL, remember including http://");
flag++;
}
// Validate Title
var title = $("#frtitle").val();
if (title=="" || title==null) { } else {
alert("Please enter only alphanumeric values for your advertisement title");
flag++;
}
// Validate Email
var email = $("#fremail").val();
if ((/(.+)#(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email==null) { } else {
alert("Please enter a valid email");
flag++;
}
if (flag == 1)
return true;
else
return false;
}
