Validade a form field only when it is visible [duplicate]

I have two group of form fields and in each group there are some fields with required attribute. However, depends on what user selects one group might be hidden and those fields should not be included in HTML form validation. So far if I have only one visible container in the form and I populate all required fields my form won't submit. Those hidden fields are still required for some reason.
Is there a way to exclude those fields from validation?
Here is example:
var checkbox = $('.account-type');
checkbox.on('change', function() {
var checked = false;
checkbox.each(function() {
checked = checked || $(this).is(':checked');
});
checkbox.prop('required', !checked);
});
$('.frm-Submit').on('submit', submitAdminFrm);
function submitAdminFrm(e) {
e.preventDefault(); // Prevnts default form submit.
alert('Submit form!');
}

How can I prevent fields inside of the hidden container from being validated?

Since both check boxes are off by default, add disabled to the inputs (selects) inside both divs. Then all you have to do is, inside .change(), toggle that disabled property according to the corresponding check box's state.
var checkbox = $('.account-type');
checkbox.on('change', function() {
var checked = false;
checkbox.each(function() {
checked = checked || $(this).is(':checked');
});
checkbox.prop('required', !checked);
$('div'+$(this).data('target') + ' :input').prop('disabled', !$(this).is(':checked'));
});
$('.frm-Submit').on('submit', submitAdminFrm);
function submitAdminFrm(e) {
e.preventDefault(); // Prevnts default form submit.
alert('Submit form!');
}

How to trigger Bootstrap 3 data-toggle with JQuery?

I have form that has two check box elements. Those two will show/hide additional form elements depends if they are checked or not. Then I have tried to implement feature where user clicks on add new record. In that case all form data should be cleared out including those two check box elements. However, I get both elements to be unchecked but data-toggle didn't hide the elements. Here is example of my code:
$('.account-type').on('change', checkFormFld);
function checkFormFld() {
var checked = false,
containerID = $(this).data('target'),
checkboxes = $('.account-type');
$('.account-type').each(function() {
checked = checked || $(this).is(':checked');
});
$(containerID + ' :input').prop('disabled', !$(this).is(':checked'));
checkboxes.prop('required', !checked); // Set required attribute to false.
}
$('#account_goback').on('click', clearForm);
function clearForm(e) {
e.preventDefault();
$('.frm-Submit')[0].reset();
$('.frm-Submit .collapse').collapse('hide');
$('.account-type').trigger('change', checkFormFld);
}

If you run example and un-comment line of code in clearForm function you can see that hidden container will slide up but won't show up if I click again. Is there a way to achieve this to work with JQuery?

Use the Collapse component methods...
https://getbootstrap.com/docs/3.3/javascript/#collapse-methods
$('.frm-Submit .collapse').collapse('toggle');

All you need to do is remove those classes which we need to collapse on Go Back Button. And remove attribute required as well
$('#user-account').removeClass('in');
$('#staff-account').removeClass('in');
$("#frm_isstaff").removeAttr('required'); // Set required attribute to false.
$("#frm_activeuser").removeAttr('required'); // Set required attribute to false.
$("#frm_systemadmin").removeAttr('required'); // Set required attribute to false.
var $checkbox = $('.account-type');
$checkbox.on('change', function() {
var checked = false,
containerID = $(this).data('target');
$checkbox.each(function() {
checked = checked || $(this).is(':checked');
});
$('div' + containerID + ' :input').prop('disabled', !$(this).is(':checked')); // Set disabled attribute on all input fields when check box is unchecked.
$checkbox.prop('required', !checked); // Set required attribute to false.
});
$('#account_new').on('click', clearForm);
function clearForm(e) {
e.preventDefault();
$('.frm-Submit')[0].reset();
$('#user-account').removeClass('in');
$('#staff-account').removeClass('in');
}

I've edited your code, but it is hard to explain. You can see and improve your code. I hope it will help you.

How to add disabled attribute to button if input and select fields are empty in jquery

<button disabled="disabled" type="submit" class="vhb next action-button" id="btn1">Continue</button>
</fieldset>
I have tried this code for the input fields but still not working
I suspect it's because of the wrong selector, and I havent added the code yet for the select field.
<script type="text/javascript">
$(document).ready(function() {
var $fields = $('#details :input');
$fields.keyup(function() {
var $emptyFields = $fields.filter(function() {
return $.trim(this.value) === '';
});
if (!$emptyFields.length) {
$('#btn1').prop('disabled', true);
} else {
$('#bt1').prop('disabled', false);
}
});
});

First step : make it disabled by default
Second step: make a function that follows this pseudo code
on input change : function
if(input 1.val()=="" || input 2.val()=="" /* etc... */) then
set disabled to true
else
remove disabled attribute
end if
end function
BTW, in JQuery disabled mustn't a prop but must be an attr.
In JQuery you can use $(/*selector*/).removeAttr(/*attribute*/) to achieve it.

$('#a').on('keyup paste propertychange input', function() {
if (this.value === "") $('#b').prop('disabled', true);
else $('#b').removeAttr('disabled');
});
$('#b').on('keyup paste propertychange input', function() {
if (this.value === "") $('#c').prop('disabled', true);
else $('#c').removeAttr('disabled');
});
$('#c').on('keyup paste propertychange input', function() {
if (this.value === "") $('#d').prop('disabled', true);
else $('#d').removeAttr('disabled');
});
$('#d').on('keyup paste propertychange input', function() {
if (this.value === "") $('#e').prop('disabled', true);
else $('#e').removeAttr('disabled');
});
$('#e').on('keyup paste propertychange input', function() {
if (this.value === "") $('#f').prop('disabled', true);
else $('#f').removeAttr('disabled');
});
$('#f').on('keyup paste propertychange input', function() {
if (this.value === "") $('#g').prop('disabled', true);
else $('#g').removeAttr('disabled');
});
$('#g').on('keyup paste propertychange input', function() {
if (this.value === "") $('#h').prop('disabled', true);
else $('#h').removeAttr('disabled');
});
$('#h').on('keyup paste propertychange input', function() {
if (this.value === "") $('#i').prop('disabled', true);
else $('#i').removeAttr('disabled');
});
$('#i').on('keyup paste propertychange input', function() {
if (this.value === "") $('#j').prop('disabled', true);
else $('#j').removeAttr('disabled');
});

<div class="col-sm-5">
<div class="checkbox">
<label>
<input type="checkbox">Current and Permanent Address are the same.
</label>
</div>
</div>
<div rv-each-address="applicant:personal_information:addresses">

<input class="form-control" rv-value="address:address"
name="model.cid" data-validate="required" />
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="city">City</label> <input

<div class="row">
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="state">Province</label> <input
rv-value="address:province" rv-enabled="address:country" type="text" id="province" placeholder="Select Province"
name="province" class="form-control typeahead">
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="country">Country</label>
<select name="gender" class="form-control" id="gender">
<option value="" disabled selected>Country</option>
<option>Philippines</option>
<option>Hong Kong</option>
<option>South Korea</option>
<option>Singapore</option>
<option>China</option>
</select>
</div>
</div>
<div class="col-md-4">
<div class="form-group">

id="postalCode" data-validate="required"
placeholder="Zip Code" />
</div>
</div>
</div>
</div>

Add the following JS to your code.
$(document).ready(function(){
$('input[type="checkbox"]').change(function(){
$('.permanentAdd').attr('disabled','disabled');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-sm-5">
<div class="checkbox">
<label>
<input type="checkbox">Current and Permanent Address are the same.
</label>
</div>
</div>
<div rv-each-address="applicant:personal_information:addresses">
<div class="row">
<div class="col-md-8">
<div class="form-group ">
<label class="control-label"><strong rv-text="address:description">Permanent Address</strong></label>
<input class="form-control permanentAdd" rv-value="address:address"
name="model.cid" data-validate="required" />
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="city">City</label> <input
rv-value="address:city" rv-enabled="address:province" type="text" class="form-control typeahead" name="city"
id="city" data-validate="required"
placeholder="Current city" />
</div>
</div>
</div>
<div class="row">
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="state">Province</label> <input
rv-value="address:province" rv-enabled="address:country" type="text" id="province" placeholder="Select Province"
name="province" class="form-control typeahead">
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="country">Country</label>
<select name="gender" class="form-control" id="gender">
<option value="" disabled selected>Country</option>
<option>Philippines</option>
<option>Hong Kong</option>
<option>South Korea</option>
<option>Singapore</option>
<option>China</option>
</select>
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="postalCode">Postal
Code</label> <input class="form-control" rv-value="address:postalCode" name="postalCode"
id="postalCode" data-validate="required"
placeholder="Zip Code" />
</div>
</div>
</div>
</div>

You can try something like this
<input type="checkbox" id="check_box" onchange="set_status();">
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="postalCode">Postal
Code</label> <div id="txt_field" name="txt_field"> </div>
<script type="text/javascript">
function set_status() {
var appendData = '';
var checkbox = document.getElementById("check_box");
if (checkbox.checked == true) {
appendData = '<input class="form-control" rv-value="address:postalCode" name="postalCode" id="postalCode" readonly="readonly" data-validate="required" placeholder="Zip Code" />';
}
else {
appendData = '<input class="form-control" rv-value="address:postalCode" name="postalCode" id="postalCode" data-validate="required" placeholder="Zip Code" />';
}
window.jQuery('#txt_field').html(appendData);
}
</script>
</div>
</div>
</div>
</div>

Here is the example how you do this thing easy. make sure you have only one checkbox in this window. else this not working, then you need to change something.
jQuery
$( "input[type=checkbox]" ).on( "click", function(){
var n = $("input[type=checkbox]:checked").length;
if(n){
$(".permanent-address").attr("disabled", 'disabled');
}else{
$(".permanent-address").removeAttr("disabled");
}
});
HTML
<div class="checkbox">
<label>
<input type="checkbox">Current and Permanent Address are the same.
</label>
</div>
<input class="form-control permanent-address" rv-value="address:address" name="model.cid" data-validate="required" />

Pure javascript anwser
function checkAddress(checkbox) {
var inputs = document.querySelectorAll('input:not([type=checkbox])');
var selects = document.querySelectorAll('select');
for (var i = 0; i < inputs.length; i++) {
inputs[i].disabled = checkbox.checked;
}
for (var i = 0; i < selects.length; i++) {
selects[i].disabled = checkbox.checked;
}
}
HTML code
<input type="checkbox" onclick="checkAddress(this)">
https://jsfiddle.net/0ba4f7jd/

Simply create a function that gets called when the checkbox is checked, which disables the div and all child elements:
$('#checkbox').change(function(){
var div = $('#everything');
if (div.attr('class')!="disabled") {
div.addClass("disabled");
$("#everything *").attr("disabled", true);
}
else {
div.removeClass("disabled");
$('#everything *').attr('disabled',false);
}
});
