Validation not working using Jquery Validation plugin

I am using the jquery validation plugin for my form validation and form is inside a modal, but it is not working. Does it work with modal? or there might be a problem with my code?
Here is my javascript:
$(document).ready(function(){
// validate the comment form when it is submitted
// $("#gen_form").validate();
// validate signup form on keyup and submit
$("#gen_form").validate({
rules: {
'fname' : {
letters: true,
maxlength: 10,
minlength:2
},
'lname' : {
letters: true,
maxlength: 10,
minlength:2
},
'email': {
email: true
},
messages: {
fname: {
maxlength: "Your last name must not consist more than 40 characters"
minlength: "Your last name must consist of at least 2 characters"
},
lname: {
maxlength: "Your last name must not consist more than 40 characters"
minlength: "Your last name must consist of at least 2 characters"
},
email: "Please enter a valid email address"
}
});
});
Here is my html form (I've already added a css for error label):
<script src="{{asset('js/jquery-2.0.0.min.js')}}" type="text/javascript">
</script>
<script src="{{asset('js/form-validation.js')}}" type="text/javascript">
</script>
<script src="{{asset('js/jquery.validate.min.js')}}" type="text/javascript">
</script>
<form method="post" action="{{route('profile.update', ['id'=> Auth::id()])}}" enctype="multipart/form-data" id="gen_form">
{{csrf_field()}}
<h4 class="modal-title" id="myModalLabel"> <b>General Information</b></h4>
<div class="col-sm-6">
<div class="form-group label-floating has-success">
<label class="control-label">Last Name</label>
<input type="text" class="form-control" id="lname" name="lname" value="{{$user->lname}}" />
<br>
</div>
</div>
<div class="col-sm-6">
<div class="form-group label-floating has-success">
<label class="control-label">First Name</label>
<input type="text" class="form-control" id="fname" name="fname" value="{{$user->fname}}" />
<p class="validations">Hello</p>
</div>
</div>
<div class="col-sm-12">
<div class="form-group label-floating has-success">
<label class="control-label">Location</label>
<input type="text" class="form-control" name="location" value="{{$user->location}}" />
</div>
</div>
<h4 class="modal-title" id="myModalLabel"> <b>Contact Information</b></h4>
<div class="col-sm-6">
<div class="form-group label-floating has-success">
<label class="control-label">Contact Number</label>
<input type="text" class="form-control" id="contact_no" name="contact_no" value="{{$user->contact_no}}" />
<p class="validations">Hello</p>
</div>
</div>
<div class="col-sm-6">
<div class="form-group label-floating has-success">
<label class="control-label">Email</label>
<input type="email" class="form-control" id="email" name="email" value="{{$user->email}}" />
<p class="validations">Hello</p>
</div>
</div>
Do anyone here have an idea what is going on?

Your script is invalid.
Perhaps try
$(document).ready(function(){
// validate the comment form when it is submitted
// $("#gen_form").validate();
// validate signup form on keyup and submit
$("#gen_form").validate({
rules: {
'fname' : {
letters: true,
maxlength: 10,
minlength:2
},
'lname' : {
letters: true,
maxlength: 10,
minlength:2
},
'email': {
email: true
},
messages: {
fname: {
maxlength: "Your last name must not consist more than 40 characters",
minlength: "Your last name must consist of at least 2 characters"
},
lname: {
maxlength: "Your last name must not consist more than 40 characters",
minlength: "Your last name must consist of at least 2 characters"
},
email: "Please enter a valid email address"
}
}
});
});
and see if you have better luck?

I think, you have some syntax errors.
Try to do something like this:
$(document).ready(function(){
// validate the comment form when it is submitted
// $("#gen_form").validate();
// validate signup form on keyup and submit
$("#gen_form").validate({
rules: {
'fname' : {
letters: true,
maxlength: 10,
minlength:2
},
'lname' : {
letters: true,
maxlength: 10,
minlength:2
},
'email': {
email: true
},
},
messages: {
fname: {
maxlength: "Your last name must not consist more than 40 characters",
minlength: "Your last name must consist of at least 2 characters"
},
lname: {
maxlength: "Your last name must not consist more than 40 characters",
minlength: "Your last name must consist of at least 2 characters"
},
email: "Please enter a valid email address"
}
});
});

You are missing a closing curly bracket and a comma at the end of the rules section, right before messages:
[...]
'email': {
email: true
},
}, /* <--- This one */
messages: {
fname: {
[...]

How to integrate ajax responses from backend to jquery validator?

I am getting a json response from my server:
{"success":false,"register_email":"","register_firstname":"","register_lastname":"<p>Please enter last name.<\/p>","register_password":"<p>Please enter your password.<\/p>","register_repeat_password":"<p>Please retype your password.<\/p>","register_about":"<p>Enter atleast 50 characters long.<\/p>"}
Now, I need to show these errors in my html page using jquery validator.
<div class="form-group">
<label for="lastname" class="col-md-3 control-label">Last Name</label>
<div class="col-md-9">
<input type="text" class="form-control" name="register_lastname" placeholder="Last Name">
</div>
</div>
<div class="form-group">
<label for="password" class="col-md-3 control-label">Password</label>
<div class="col-md-9">
<input type="password" class="form-control" id="register_password" name="register_password" placeholder="Password">
</div>
</div>
In case of front-end check, I am successfully using jquery validator.
$('#signupform').validate({
rules: {
register_email: {
required:true,
email:true
},
register_firstname: "required",
register_lastname: "required",
register_password: {
required:true,
minlength:6
},
register_repeat_password: {
required:true,
equalTo: "#register_password"
},
register_about: {
required:true,minlength:50
},
},
messages: {
register_email: "Please Enter your email.",
register_firstname: "Enter your first name",
register_lastname: "Enter your last name.",
register_password: {
required: "Please enter your password.",
minlength: "Your password should be of minimum 8 characters."
},
register_repeat_password: {
required: "Please retype your password",
equalTo: "Your password don't match."
},
register_about: "Please Enter at least 50 characters."
},
errorElement: 'div',
errorClass: 'alert alert-danger fade in',
I want to achieve the same in case of backend check.
I googled, I came to know about remote attribute in jquery validator, but it works for only one field, at a time. I want to integrate backend responses in each and every case.

Jquery slide up function not activating in contact form script

Everything is working on this contact form except for the last bit using the slide up function to replace the contact form with a thank you message and I just can't seem to hack my way to a solution.
You fill out the form, hit submit, the email gets sent, and the loading gif appears, but the slideup animation never happens and the thank you image never shows.
<!--CONTACT PANEL-->
<div id="contact-panel">
<div class="top">: : CONTACT ME : :</div>
<form id="contactform" method="post">
<ol class="forms">
<fieldset>
<label for="name"><input type="text" name="name" id="name" value="" placeholder="Name:" required minlength="2" /></label>
</fieldset>
<p style="margin-top: -10px;"><label for="name" class="error"></label></p>
<fieldset>
<label for="email"><input type="text" name="email" id="email" value="" placeholder="Email:" required /></label>
</fieldset>
<p style="margin-top: -10px;"><label for="email" class="error"></label></p>
<fieldset>
<label for="message"><textarea name="message" id="message" placeholder="Question/Comments:" required ></textarea></label>
</fieldset>
<p style="margin-top: -5px;"><label for="message" class="error"></label></p>
<li class="buttons"><button type="submit" id="submitemail">Send Email »</button><input type="hidden" name="submitted" id="submitted" value="true" /></li>
</ol>
</form>
</div>
Here's the JS...
$(document).ready(function () {
$("#contactform").validate({
rules: {
name: {
required: true,
minlength: 2
},
email: {
required: true,
email: true
},
message: {
required: true,
minlength: 10
},
},
messages: {
name: {
required: "*Please enter your name.",
minlength: "*Your name must consist of at least 2 characters."
},
email: "*Please enter a valid email address.",
message: "*Please, say something at least 10 characters long.",
},
submitHandler: function(form) {
$('#submitemail').hide();
$("#contactform li.buttons").append('<img src="media/contact/loading.gif" alt="Loading" id="loading" />');
$.post('code/form-contact/submitcontactform.php',
$('form#contactform').serialize(),
function(data){
$("#contactform").slideUp("normal", function() {
$("#contactform").before('<img src="media/contact/contact_thankyou.png" alt="Thank You" id="thankyou" />');
});
});
},
})
return false;
});
I have tried a lot of different ways but I just don't know enough beyond guessing and trial and error. Any help would be welcomed.

I did some changes in messages json as below:
messages: {
name: {
required: "*Please enter your name.",
minlength: "*Your name must consist of at least 2 characters."
},
email:
{
email: "*Please enter a valid email address.",
required: "Please enter email address."
},
message:
{
minlength: "*Please, say something at least 10 characters long.",
required: "Please enter message"
}
},
to make it work in fiddle, I had to remove post call as jsfiddle doesn't support it:

Multiple validation in javascript/jquery/html form

I am using bootstrap3 form with jquery/javascript to validate input. This was taken from here
Here is part of my form:
<form id="contact-form" action="#" class="form-horizontal">
<fieldset>
<div class="form-group">
<label class="sr-only" for="name">Your Name</label>
<div class="controls">
<input type="text" class="input-xlarge form-control" name="name" id="name" placeholder="Your Name">
</div>
</div>
<div class="form-group">
<label class="sr-only" for="email">Email Address</label>
<div class="controls">
<input type="text" class="input-xlarge form-control" name="email" id="email" placeholder="Email">
Here is the javascript:
<script>
$(document).ready(function(){
jQuery.validator.setDefaults({
errorClass: "help-block"
});
$('#contact-form').validate({
rules: {
name: {
minlength: 3,
regex: "/^[A-Za-z\']*$/",
required: true
},
email: {
required: true,
email: true
},
subject: {
minlength: 2,
required: true
},
message: {
minlength: 2,
maxlength: 400,
required: true
}
},
highlight: function(element) {
$(element).closest('.control-group').removeClass('success').addClass('error');
},
success: function(element) {
element
.text('OK!').addClass('valid')
.closest('.control-group').removeClass('error').addClass('success');
}
});
}); // end document.ready
</script>
The required field and number of digits work wonderfully well. I also intend to add further validation, for example, accept alphabets in name field. I have tried using regex but does not seem to be working.
how to use regex (or multiple) validation in this type of javascript validation ?
how to give appropriate error message when a field has multiple validations (only alphabets and more than 3 characters) ?
I am very new to web development, so these might appear noob questions. Just getting hands on html now. Please guide in right direction.

For email you should add something like this:
$.validator.addMethod("email", function(value, element) {
return this.optional(element) || /^[a-zA-Z0-9._-]+#[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$/i.test(value);
}, "Invalid email address");
then rules for email should be:
email: "required email",

jQuery.validate.js equalTo refuses to work

I am trying to validate that my one password equals the other. The system keeps flagging the passwords not equal error.
Let me post my code:
<div class="fieldWrapper">
<label for="password" id="id_password">Password: </label>
<input id="id_password" type="password" placeholder="Password" name="password" maxlength="128" class="valid">
</div>
<div class="fieldWrapper">
<label for="password_verification">Confirm:</label>
<input id="id_password_verification" type="password" placeholder="Confirm" name="password_verification" maxlength="128">
</div>
$(document).ready(function()
{
$("#signup-form").validate({
rules: {
password: {
required: true,
minlength: 5
},
password_verification: {
required : true,
equalTo: "#id_password"
}
},
messages: {
password: {
required: "Please provide a password",
minlength: "Your password must be at least 5 characters long"
},
password_verification: {
required: "Please enter your password again",
equalTo: "Please enter the same password as above"
},
},
submitHandler: function(form) {
form.submit();
}
});
});
Does anyone have any clue where I am going wrong here? Note that my form has the id signup-form.

You have dupplicate id in your HTML:
<label for="password" id="id_password">Password: </label>
remove id from the label.
