Validation issue in select2 multiple select

I'm trying to validated select2 and other input fields they are validating as shown in code snippet, but i do not want to show text on validation error instead i want to show red border around select2 and textbox, i have used that too in error placement and highlight section but it is not showing any red border around fields.
$("#singleselect").select2({ placeholder: "Please select",width: '100%'});
$.validator.messages.required = '';
$("form#msform").validate({
ignore:'input[type=hidden]',
rules:
{
"singleselect[]": { required: true },
name: { required: true }
},
errorPlacement: function (error, element) {
var elem = $(element);
if (elem.hasClass("select2-hidden-accessible")) {
element = $("#select2-" + elem.attr("id") + "-container").parent();
error.insertAfter(element);
}
else {
error.insertAfter(element);
}
},
highlight: function (element, errorClass, validClass) {
var elem = $(element);
if (elem.hasClass("select2-hidden-accessible")) {
$("#select2-" + elem.attr("id") + "-container").parent().addClass(errorClass);
}
else if(elem.is(':checkbox'))
{
elem.addClass("parent-error");
}
else {
elem.addClass(errorClass);
}
},
unhighlight: function (element, errorClass, validClass) {
var elem = $(element);
if (elem.hasClass("select2-hidden-accessible")) {
$("#select2-" + elem.attr("id") + "-container").parent().removeClass(errorClass);
}
else if(elem.is(':checkbox'))
{
elem.removeClass("parent-error");
}
else {
elem.removeClass(errorClass);
}
},
success: function (label, element) {
//jQuery(element).parent().removeClass('has-error');
},
submitHandler: function(form) {
form.submit();
}
});
span.error{
outline: 1px solid red;
border: 1px solid red;
}
.parent-error {
outline:1px solid red;
background:red;
}
#msform label.error {
display: none !important;

</form>

Your problem has to do with your targeting logic.
if (elem.hasClass("select2-hidden-accessible"))
You do not have anything in the DOM with that class. The hidden select element only has a class of sl.
Then you are trying to target an element with an ID of select2-" + elem.attr("id") + "-container", however, no such thing exists. I set up a jsFiddle, inspected the DOM, and the ID of the container is s2id_singleselect.
https://jsfiddle.net/8ganq0mt/1/
I also removed a lot of unnecessary code. There is no need to blank out the actual message or hide with CSS. If you don't want error messages, then don't use the errorPlacement callback to place the messages; just return false and messages are gone.
errorPlacement: function() {
return false;
},

How to use Jquery validation on the radio button with respected fields?

My issue is regarding jquery validation. I have a form and validation is working on input field but I am confused how to use the validation on the radio button because I have three radio buttons and the user can choose only one. All the radio button have their respected fields. I have to set the validation on it.
Example: I choose the first radio then the user should enter the book1 and book2 fields as well. If you choose the second radio then the user should enter the fruit1 and fruit2 fields value.
if user choose only radio button and without filling the fields details and clicked on submit then validation should display.
I tried some code. It's working for first radio button but what if any user chooses a second radio button?
This is the output I am getting.
Radio button Book is checked with Jquery validation if fields are empty
Notice here I choose fruit and clicked on submit button but validation is not displaying
The reason was I am not getting because I added only book radio button validation. Now how to use for fruit and subject?
book1: {required: true},
book2: {required: true}
$(document).ready(function() {
$("input[name='books_fruit_sub']").click(function() {
var test = $(this).val();
$(".show_fields").hide();
$("#show" + test).show();
});
$('#form').validate({ // initialize the plugin
rules: {
mobile: {
required: true,
number: true,
minlength: 10,
maxlength: 10
},
book1: {
required: true
},
book2: {
required: true
}
},
submitHandler: function(form) { // for demo
form.submit();
}
});
});

text-decoration: none;
margin: 0;
padding: 0;
}
ul li {
display: inline-block;

Just use a function that return true or false depending on if the related radio buttton is selected or not.
book1: {
required: function() {
return $('#books').is(':checked');
}
},
book2: {
required: function() {
return $('#books').is(':checked');
}
},
fruit1: {
required: function() {
return $('#fruit').is(':checked');
}
},
fruit2: {
required: function() {
return $('#fruit').is(':checked');
}
},
..
To be consequent use the plural form "fruits" and "subjects" as you did for "books" for your radio-buttons.
Here is your modified and working code in plunker.

You don't need jQuery for that. Using ES20xx, data-attributes and css it's fairly easy to create your own form validation. Let's, just for fun, work out an example based on your code.
We need a function to determine the chosen value of a radio button, that's checkRadio in the snippet;
We need a function to show or hide fields belonging to a radio button choice, that's switchFieldsBasedOnRadioChoice in the snippet. That function is activated by clickHandling. We use the chosen value from checkRadio to identify div#show[chosen value]] to be able to show the right div containing the input elements belonging to the chosen value;
We need an Object containing some methods to check fields denoted in html by data-check and activated by the value of [data-check], it's called fieldChecks;
We need a handler function for the (submit) button which will check all fields denoted by [data-check] for field value validity and warn if the field value is not valid, that's checkValues, activated by clickHandling;
We also create a focusin-handler that removes warnings from a previous input values check if the user clicks on or focuses one of the form fields;
We use data-attributes and css to style and display the warning values. Every text-input is wrapped in a div. We use the css class .invalid for (input fields container)-div that to style the warnings on the containing input fields (if applicable).
Notes
the handlers (click, focusin) in this snippet use event delegation.
client side validation is never sufficient. You should always check the fields values server side too before handling them at the server.

Remove the rule for book1 and book2 from validator initialization and in your click handler just add this
$(".show_fields").find("input").removeAttr("required");
$("#show" + test).find("input").attr("required" , "required");
Also in html add required attribute to both inputs book1 and book2

Text field group validation using jquery validator

Currently working with jquery group field validation. I am using the great jquery validation plugin I have searched through SO actually I got some idea for group validation with my current code I can able to validate the three field and when i typed in any of the field the errClass getting disappear but the validation count was not detecting.
I was not able to figure out what was the problem
Here is the jquery code
$(document).ready(function () {
$(".error_msge").hide();
$(".basicForm").validate({
ignore: false,
onkeyup: false,
showErrors: function (errorMap, errorList) {
var errors = this.numberOfInvalids();
if (errors) {
var message = errors == 1 ? 'You missed 1 field. It has been highlighted' : 'You have missed ' + errors + ' fields. Please fill the highlited field before submit.';
$("#error_message").html(message);
$(".error_msge").show();
} else {
$(".error_msge").hide();
}
this.defaultShowErrors();
},
errorPlacement: function () {
return false;
},
highlight: function (element) {
if ($(element).is(':radio')) {
} else {
$(element).addClass('errRed');
}
$(element).prevAll('label').find('span.required-star').addClass('text-error-red').removeClass('text-error-black');
},
unhighlight: function (element) {
if ($(element).is(':radio')) {
} else {
$(element).removeClass('errRed');
}
$(element).prevAll('label').find('span.required-star').addClass('text-error-black').removeClass('text-error-red');
},
rules: {
txt_Po: {
require_from_group: [1, ".txt_Add"]
},
txt_Bdg: {
require_from_group: [1, ".txt_Add"]
},
txt_St: {
require_from_group: [1, ".txt_Add"]
}
}
});
});
Here is my HTML code
<span id="error_message" class="error_msge">
</span>
<form autocomplete="off" class="basicForm" id="basicForm" method="POST">
<!--first field-->
<label>P.O.Box</label>
<br/>
<input type="text" class="ipt_Field txt_Add" id="txt_Po" name="txt_Po" />
<!--second field-->
<label>Building</label>
<br/>
<input type="text" class="ipt_Field txt_Add" id="txt_Bdg" name="txt_Bdg" />
<!--third field-->
<label>Street</label>
<br/>
<input type="text" class="ipt_Field txt_Add" id="txt_St" name="txt_St" />
<button class="btn-next" id="btn-Next" >Next</button>
</form>
Here is the CSS code
.errRed {
color: black !important;
border: 1px solid #EA373D !important;
padding: 6px !important;
}
.error_msge {
border:1px solid red;
width: 450px;
margin: 0px auto;
text-align: center;
background-color: #FFBABA!important;
padding: 5px;
}

jQuery validation for textbox and Radio buttons

I have a form in "jQuery Dialog Box" and in which there is a <textarea> and the other is a pair of <input type="radio" /> buttons
Both are required fields and if the user leaves the testarea empty or do not check any of the radio , the user should get the message and the Dialog box should not close.
I have tried doing the validation, its working for Textarea but not for the radio buttons.
Here is the Fiddle I created : http://jsfiddle.net/JLDf5/
Here is the code for the same:
HTML
<div id="sessionReason" title="End Transaction">
<p class="validation-summary-errors marginBottom10">Provide the following information to proceed:</p>
<div class="marginBottom" id="sessionDocumentMessage">
<label class="marginBottom5 marginTop10">Return the document?</label>
<br>
<label>
<input type="radio" name="sessionDocuments" />Return</label>
<br>
<label>
<input type="radio" name="sessionDocuments" />Keep</label>
<br>
</div>
<p class="marginBottom5" id="sessionReasonMessage">Reason for ending the transaction:</p>
<textarea id="sessionReasonBox" class="reasonBox"></textarea>
</div>
jQuery
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReason").dialog({
buttons: {
"End Transaction": function () {
var sessionReasonBox = $("#sessionReasonBox").val();
if ($('[name="sessionDocuments"]').is(':checked')){
$('#sessionReason .validation-summary-errors').show();
$("#sessionDocumentMessage label").addClass("redtext");
}
if (sessionReasonBox == "") {
$('#sessionReason .validation-summary-errors').show();
$("#sessionReasonMessage").addClass("redtext");
return false;
}
else {
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReasonMessage").removeClass("redtext");
}
$(this).dialog("close");
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
Please suggest!

IF blocks needs ELSE IF and the close should be inside the IF block. and check for ! (not) radio checked. and no need return false.
if (!$('[name="sessionDocuments"]').is(':checked')){
$('#sessionReason .validation-summary-errors').show();
$("#sessionDocumentMessage label").addClass("redtext");
}
else if (sessionReasonBox == "") {
$('#sessionReason .validation-summary-errors').show();
$("#sessionReasonMessage").addClass("redtext");
//return false;
}
else {
$('#sessionReason .validation-summary-errors').hide();
$("#sessionReasonMessage").removeClass("redtext");
$(this).dialog("close");
}
Here is the fiddle

I fixed the issue with the below code:

checkboxes tiny and unclickable in chrome

For some reason the check-boxes on this form are not clickable and are very, very, tiny using google chrome. When using firefox the checkboxes work great. I'm not exactly sure what to look for... It's really strange!!! Is there something wrong with the way I'm using <form>? When I use inspector even if I disable all css the checkboxes are still tiny. not sure what is going on. reset browser cache etc. really could use some help.
