Show/hide div and clear filed value when change

I have some div that will show depending on the select value. Suppose there are two input fields name 'Apartment and Bechelor' If I select 'Apartment' some div and select field will show related to the apartment. The problem I am facing is, I can't clear the field value when selecting another. Like, after selecting 'Apartment', I will select Bachelor. Now it should be clear the value of the field which was under the apartment so that If I again select 'Apartment', I will get default values or clean fields.
<div id="residential" >
<input type="radio" value="apartment" id="type_apartment" name="type" >
<label for="type_apartment" class="radio-inline"> Apartment/Flat </label>
<input type="radio" value="bachelor" id="type_bachelor" name="type">
<label for="type_bachelor" class="radio-inline"> Bechelor </label>
</div>
<!-- show this when apartment select -->
<div class="form-group " id="tenant-flat">

<option value="">Anyone</option>
<option value="family">Family</option>
<option value="bechelor" >Bechelor</option>
</select>
</div>
<div class="form-group " id="flat-type">

<script>
$(document).ready(function(){
$('#r-type').hide();
$('#tenant').hide();
$('#tenant-flat').hide();
$('#flat-type').hide();
$('.pretty input[type="radio"]').click(function(){
if($(this).attr('value') == 'apartment'){
$('#tenant-flat').show();
}
else{
$('#flat-type').hide();
}
});
var showDiv = document.getElementById("tenant-type");
showDiv.onchange = function(){
var hiddenDiv = document.getElementById("flat-type");
hiddenDiv.style.display = (this.value == "family") ? "block":"none";
var genderDiv = document.getElementById("gender");
genderDiv.style.display = (this.value == "bechelor") ? "block":"none";
};
$('.pretty input[type="radio"]').click(function(){
if($(this).attr('value') == 'bachelor' || $(this).attr('value') == 'sublet' || $(this).attr('value') == 'hostel' ){
$('#r-type').show();
$('#tenant').show();
$('#tenant-type').hide();
}
else{
$('#r-type').hide();
$('#tenant').hide();
$('#tenant-type').show();
}
});
});
</script>

to reset the dropdown options you can set the value of the select elements selectIndex property to 0 with this line:
$('.form-control').prop('selectedIndex', 0);
and in your code:
$(document).ready(function(){
$('#r-type').hide();
$('#tenant').hide();
$('#tenant-flat').hide();
$('#flat-type').hide();
$('#residential input[type="radio"]').click(function(){
if($(this).attr('value') == 'apartment'){
$('#tenant-flat').show();
$('#flat-type').show();
$('#r-type').hide();
$('#tenant').hide();
}
else{
$('#r-type').show();
$('#tenant').show();
$('#flat-type').hide();
$('#tenant-flat').hide();
}
$('.form-control').prop('selectedIndex', 0);
});
$('#tenent-type').on('change', function() {
if($('#flat-type').val =='family') {
$('#flat-type').show();
} else {
$('#flat-type').hide();
}
if($('#gender').val =='bechelor') {
$('#gender').show();
} else {
$('#gender').hide();
}
});
});

how to clone div bassed select option

i have select option with count of numbers so i need now when user choose any number clone div tag personal information by this number ex: - select 8 clone 8 time ..
i try do that by use( for loop )but i have problem when run i see clone over this number ex:- choose 8 clone 16 time
this is html code and my try js code
$('#c3').change(function() {
$('.cloneHere').empty();
var count = $('#c3').val();
for (i = 1; count > i; i++) {
var clone = $('.rowClone').clone();
$('.cloneHere').append(clone);
}
});

The problem you are facing comes from this line: var clone = $('.rowClone').clone();
the first clone is fine because only 1 .rowClone exist, next time multiple .rowClone exist and it appends all of those.
You have 2 solutions, either use var clone = $('.rowClone:first').clone(); or move var clone = $('.rowClone').clone(); before your for loop
Demo of the problem, run it and look at the console
$('#c3').change(function() {
$('.cloneHere').empty();
var count = $('#c3').val();
for (i = 1; count > i; i++) {
console.log("Number of .rowClone that exist = " + $('.rowClone').length)
var clone = $('.rowClone').clone();
$('.cloneHere').append(clone);
}
});

Last-child not working inside iteration of div

In browser, the HTML is generated dynamically and is rendered as
<div id="dynamic-relationship-details">
<div id="count-status0" class="relationship-container form-group">

<div class="col-sm-2">

</div>
The code is
// Relationship details Array
$(".relationship-container").each(function(i, obj) {
var $this = $(this);
$this.find("select").each(function() {
var relationshipTypeValue = $(this).val();
var relationshipName =$this.find("input[type=text]:first-child").val();
var relationshipContactNumber =$this.find("input[type=text]:last-child").val();
var innerRelationshipArray = {};
innerRelationshipArray = {
relationshipTypeValue: relationshipTypeValue,
relationshipName: relationshipName,
relationshipContactNumber: relationshipContactNumber
};
relationship_details_array.push(innerRelationshipArray);
});
});
I am trying to fetch values of contact numbers i.e with id's relationship-type-contact(n) values in the line "
var relationshipContactNumber =$this.find("input[type=text]:last-child").val();"
This is fetching values of first-child textboxes in the variable relationshipContactNumber in the loop.
Please help !!!

This should work, use the .first() and .last() selectors.
Another way, if you have access to alter the HTML, is to add class names for the input fields and select them by using that instead.
function getData() {
var relationship_details_array = [];
// Relationship details Array
$(".relationship-container").each(function(i, obj) {
var $this = $(this);
$this.find("select").each(function() {
var relationshipTypeValue = $(this).val();
var relationshipName = $this.find("input[type=text]").first().val();
var relationshipContactNumber = $this.find("input[type=text]").last().val();
var innerRelationshipArray = {};
innerRelationshipArray = {
relationshipTypeValue: relationshipTypeValue,
relationshipName: relationshipName,
relationshipContactNumber: relationshipContactNumber
};
relationship_details_array.push(innerRelationshipArray);
});
});
console.log(relationship_details_array);
}
$("#getData").on("click", getData);

i want my dropdown list to show a form when clicked and i have tried using javascript function here, but it is not working the form is showing as it is and nothing is working with onclick. Help me to do it as the form is not being shown when clicked but it is shown directly
this is the javascript code;
<script>
function myFunction() {
var x = document.getElementById("restaurant-form");
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
}
</script>

Yes as per #gurvder372 you can't use onclick for option.You can also use an inline event assignment for this Like:
<select class="form-control" id="" onchange="javascript:return myFunction(event);">
<option value="" hidden>Select Venue Type</option>
<option>Theme Restaurant</option>
<option>Blah restaurant</option>
<option>Flana Restaurant</option>
<option>Woops Restaurant</option>
</select>
<script>
function myFunction(event)
{
var index_opt = event.target.selectedIndex;
if ( index_opt > 0 )
{
var x = document.getElementById("restaurant-form");
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
}
}
</script>

onclick is not supported on option tag, You need to add event listener to the select instead
document.querySelector( "select[id]" ).addEventListener( "change", myFunction );
In the myFunction method you can show/hide form based on which option is selected.
function myFunction(event)
{
var selection = event.target.selectedIndex;
var x = document.getElementById("restaurant-form");
x.style.display = selection >= 1 ? "block" : "none";
}
Demo
function myFunction(event)
{
var selection = event.target.selectedIndex;
var x = document.getElementById("restaurant-form");
x.style.display = selection >= 1 ? "block" : "none";
}
document.querySelector( "select[id]" ).addEventListener( "change", myFunction );
<div class="col-lg-10">
<div class="form-group">
<select class="form-control" id="" >
<option value="">Select Venue Type</option>
<option>Theme Restaurant</option>
<option>Blah restaurant</option>

How to Show/Hide Div on SelectedIndex in Bootstrap 3?

I have this code:
<div class="form-group">
<label for="slDisThrough" class="col-sm-1 control-label">Distributed Through</label>
<div class="col-sm-11">
<select name="slDisThrough" id="slDisThrough" class="form-control">
<option value="0">-Select-</option>
<option value="1">Agent</option>
<option value="2">Retail</option>
</select>
</div>
</div>
<div id="slAgentID" class="hide">
<div class="form-group">
<label for="slAgent" class="col-sm-1 control-label">Agent</label>
<div class="col-sm-11">
<select name="slAgent" class="form-control">
<option value="0">-Select-</option>
<option value="1">Show</option>
<option value="2">Hide</option>
</select>
</div>
</div>
</div>
<div id="slRetailID" class="hide">
<div class="form-group">
<label for="slRetail" class="col-sm-1 control-label">Retail</label>
<div class="col-sm-11">
<select name="slRetail" class="form-control">
<option value="0">-Select-</option>
<option value="1">Hide</option>
<option value="2">Show</option>
</select>
</div>
</div>
</div>
Check this Fiddle
if(document.getElementById("slDisThrough").selectedIndex == 1) {
document.getElementById("slAgentID").style.display = ""; }
else { document.getElementById("slAgentID").style.display = "none"; }
if(document.getElementById("slDisThrough").selectedIndex == 2) {
document.getElementById("slRetail").style.display = ""; }
else { document.getElementById("slRetail").style.display = "none"; }
I need to Show/Hide the DIVs on Selected Value, I was previously using it with JavaScript, but stuck with Bootstrap.

Since you load jQuery, better use it like this:
$('#slDisThrough').on('change', function(){
if ($(this).val() == 1 ) {
$('#slAgentID').removeClass('hide');
$('#slRetailID').addClass('hide');
}
if ($(this).val() == 2 ) {
$('#slAgentID').addClass('hide');
$('#slRetailID').removeClass('hide');
}
})
