JS validation doesn't run after I enter a valid input and submit the form with rest of the input fields empty

I am developing a web directory with a form on one of its pages. JS validation plug in is used. While submitting the form without filling any Input fields, the form throws errors below each input field as expected! But submitting the form with just one input box filled in refreshes the current page as the action value is set to current page with PHP codes in it, instead of staying on the same page to continue to throw errors for the rest of the fields that are yet to be filled in! I have searched online to find nothing useful in figuring out what is wrong with the script. Could anyone here please look into the code below and recommend the best solution? Thanks.
$(document).ready(function() {
$("#userForm").validate({
rules: {
cname: {
required: true,
lettersonly: true,
minlength: 3
},
cemail: {
required: true,
email: true
},
cphone: {
required: true,
number: true,
minlength: 10,
maxlength: 10
},
cbusiness: {
required: true,
url: true
},
cbcategory: {
required: true,
minlength: 6
},
curl: {
required: true,
minlength: 6
},
},
messages: {
cname: "Please enter your name",
cemail: "Please enter a valid email address",
cphone: {
required: "Please enter your phone number",
number: "Please enter only numeric value"
},
cbusiness: {
required: "Please enter your business",
},
cbcategory: {
required: "Please enter a business category",
},
curl: {
required: "Please enter the URL to your website",
},
}
});
});
The form is as below.
<form action="" method="post" name="userForm" id="userForm">
<input type="text" name="cname" id="cname" placeholder=" Your Name">
<input type="text" name="cemail" id="cemail" class="email" placeholder="Your Email">
<input type="text" name="cphone" id="cphone" placeholder="Your Phone">
<input type="text" name="cbusiness" id="cbusiness" class="email" placeholder=" Your Business">
<input type="text" name="cbcategory" id="cbcategory" placeholder="Business category">
<input type="text" name="curl" id="curl" class="email" placeholder="URL"><br>
<label for='message'>Enter the code in the box below : </label>
<img src="captcha.php?rand=<?php echo rand();?>" id='captchaimg'>
<input type="text" id="captcha_code" name="captcha_code">
<input type="submit" name="Submit" id="Submit" value="Submit" class="button1"><br>
Can't read the image? click <a href='javascript: refreshCaptcha();'>here</a> to refresh.
</form>

Assuming you have included the validation libraries corectly, you will have to set messages for all of the validation types like:
messages: {
cname: {
required: "Please enter your name",
lettersonly: "Letters only",
minlength: "Min length 3 required"
},
cemail: {
required: "Please enter a valid email address",
email: "Invalid email"
}
}
Working JSFIDDLE.
You have to include the plugin files something like this:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.16.0/additional-methods.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.16.0/jquery.validate.js"></script>
UPDATE:
After discussing with OP on chat, we came to the conclusion that the plugin files had to be included correctly and there was an incompatibility between the jQuery version(v 1.7.1) he used and the plugin version(v 1.16.0). So we had to add a custom method for lettersonly.
The code for custom method:
jQuery.validator.addMethod("lettersonly", function(value, element) {
return this.optional(element) || /^[a-z]+$/i.test(value);
}, "Letters only please");

Combining two validations in jQuery for password field

I have a signup form, and I am using a 3rd party library to validate the inputs. This library provides very nice and cool effects for validation, but I need to do another verification to make sure the password and confirm password are matching. how can I do that via jQuery? Here is my code:
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control" name="password" />
</div>
<div class="form-group">
<label>Retype Password</label>
<input type="password" class="form-control" name="password2" />
</div>
and jQuery part:
$('#registrationForm').formValidation({
framework: 'bootstrap',
fields: {
password: {
validators: {
notEmpty: {
message: 'The password is required'
}
}
},
password2: {
validators: {
notEmpty: {
message: 'Password conformation is required'
},
equalTo: {
field: 'password',
message: 'The password cannot be the same as username'
}
}
}
}
});
What should I put instead of the question marks, to address my issue? Or maybe I am completely wrong with the syntax?

Working Fiddle
Html :
<form id="formCheckPassword">
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control" name="password" id="password" />
</div>
<div class="form-group">
<label>Retype Password</label>
<input type="password" class="form-control" name="cfmPassword" id="cfmPassword" />
</div>
<input type="submit" value="submit" />
</form>
and Jquery Rules :
$("#formCheckPassword").validate({
rules: {
password: {
required: true,
minlength: 6,
maxlength: 10,
},
cfmPassword: {
equalTo: "#password",
minlength: 6,
maxlength: 10
}
},
messages: {
password: {
required: "the password is required"
}
}
});
Update as per request :
$('#RegistrationForm').formValidation({
framework: 'bootstrap',
fields: {
password: {
validators: {
identical: {
field: 'confirmPassword',
message: 'The password and its confirm are not the same'
}
}
},
confirmPassword: {
validators: {
identical: {
field: 'password',
message: 'The password and its confirm are not the same'
}
}
}
}
});

I don't see it working in that syntax. If you want to do it via jQuery (as you mentioned), you can simply check the values:
var password1 = $('input[name=password]').val();
var password2 = $('input[name=password2]').val();
var match = password1 == password2

jquery validate plugin- required validation doesn't work as it should

I use jquery validate plugin.
One of my demand is to show the error message when the field lost it focus.
rules: {
firstName: {
required: true,
//minlength: 1,
maxlength: 30
},
lastName: {
required: true,
//minlength: 1,
maxlength: 30
}
},
messages: {
firstName: {
required: "Please enter your first name",
maxlength: "Please enter a value less than or equal to 30."
},
lastName: {
required: "Please enter your last name",
maxlength: "Please enter a value less than or equal to 30."
}
}
<div class="inline ui-grid-a">
<div class="firstInput ui-block-a">
<input type="text" class='signup-input first-name lettersOnly required' name="firstName" id="firstName" placeholder="" required value="${user?.firstname}">
</div>
<div class="secInput ui-block-b">
<input type="text" class='signup-input last-name lettersOnly required' name="lastName" id="lastName" placeholder="" required value="${user?.lastname}">
</div>
</div>
The maxlength for example works as expected , but the required start to work on focus out only if some validation happened before.

Validation plugin files are not working

I am doing my form validation with jquery validation plugin. Everything seems fine but its not working. No message appears. Or may be its due to files that I have included.

When using any jQuery plugin, you must load jQuery first. You are also including the plugin twice. You must not include each plugin more than once... preferably use the latest version.
This is correct...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
Otherwise, use the latest plugin version supported by your version of jQuery...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.13.1/jquery.validate.js"></script>

Call javascript function on submit form

I am trying to call JavaScript function while submitting the form.
Here is code but while submitting function not called, please suggest something and I want to show error messages using javascript method as well , how can I show error messages in validation using JavaScript.
<form id="register" name="register" onsubmit="validateForm()">
<label for="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password"><br><br>
<label for="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email"> Email </label><br>
<input type="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit">Submit</button>
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.8/jquery.validate.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
},
"email": {
required: true,
}
}
});
});
</script>
and here is JavaScript code
function validateForm()
{
var password = document.forms["register"]["Password"].value;
var con-password = document.forms["register"]["Confirm-Password"].value;
if(password != con-password)
{
document.getElementById('password-error').style.visibility='visible';
alert("not matched");
}
alert("matched");
}

This is probably due to a syntax error in your script. When you see errors like that, look into the JavaScript console of your browser.
In this case, con-password is not a valid variable name. What JavaScript sees is:
var con - password ...
i.e. the code says "substract password from con". Try an underscore instead:
var con_password ...

Do not need to do anything extra for password matching, just add equalTo: "#Password" to it as shown in the below example:
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"
},
"email": {
required: true,
}
},
messages: {
Password: {
required: "Please provide a password",
minlength: "Your password must be at least 5 characters long"
},
Confirm-Password: {
required: "Please provide a confirm password",
equalTo: "Please enter the same password as above"
}
},
submitHandler: function(form) {
// Your function call
return false; // return true will submit form
}
});
});
Working example:
<form id="register" name="register" action="" method="post">
<label for="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password"><br><br>
<label for="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm_Password" name="Confirm_Password" placeholder="Confirm Password" ><br><br>
<label for="email"> Email </label><br>
<input type="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit">Submit</button>
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.8/jquery.validate.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm_Password": {
required: true,
equalTo: "#Password"
},
"email": {
required: true,
}
},
messages: {
Password: {
required: "Please provide a password",
minlength: "Your password must be at least 5 characters long"
},
Confirm_Password: {
required: "Please provide a confirm password",
equalTo: "Please enter the same password as above"
}
},
submitHandler: function(form) {
// Your function call
return false; // return true will submit form
}
});
});
</script>

Maybe instead of checking if passwords matches you can add new rule in validation?
something like:
... "Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"} ....
and for messages add:
... messages: {
"Password": "Your message",
}...
and all in all something like this: `
$(document).ready(function () {
$("Your form name").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"
},
"email": {
required: true,
email: true
}
}
messages: {
"Password": "Your message",
"email": "Your Message",
},
submitHandler: function (form) {
form.submit();
}
});
});`

try this. i add onclick event on the submit button to call the function validateForm()
html
<form id="register" name="register">
<label for ="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for ="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password" ><br><br>
<label for ="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email" > Email </label><br>
<input type ="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit" onclick="validateForm()">Submit</button>
</form>
this is the validateForm()
<script type="text/javascript">
function validateForm() {
var username = $('#Username'),
password = $('#Password'),
confirm = $('#Confirm-Password'),
email = $('#email');
$('#register').submit(function(ev){
// check if all fields is not empty
if(username.val() === '' || password.val() === '' || confirm.val() === '' || email.val() === '') {
ev.preventDefault(); // prevent form submit
alert('All fields are required.'); //alert message
//check if password and confirm password is equal
} else if(password.val() != confirm.val()){
ev.preventDefault(); // prevent form submit
alert('password did not match.'); //alert message
} else {
return true; // submit form if validation has passed.
}
});
}
</script>

May be you missed - you need to use method="post" in
http://jsfiddle.net/dLbLS/
<form id="register" name="register" method="post" onsubmit="validateForm();" >
<label for ="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for ="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password" ><br><br>
<label for ="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email" > Email </label><br>
<input type ="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit" >Submit</button>
</form>

Use this code
<input type="button" id="close" value="Submit" onClick="window.location = 'validateForm()'">
