I am trying to delete checked checkboxes in jQuery, but when i want to get state of checkbox i get error message.
jsfiddle
<div class="control-group">
<label class="checkbox"><input value="0" type="checkbox">Message 0</label>
<label class="checkbox"><input value="1" type="checkbox">Message 1</label>
<label class="checkbox"><input value="2" type="checkbox">Message 2</label>
<label class="checkbox"><input value="3" type="checkbox">Message 3</label>
<label class="checkbox"><input value="4" type="checkbox">Message 4</label>
<label class="checkbox"><input value="5" type="checkbox">Message 5</label>
<label class="checkbox"><input value="6" type="checkbox">Message 6</label>
<label class="checkbox"><input value="7" type="checkbox">Message 7</label>
<label class="checkbox"><input value="8" type="checkbox">Message 8</label>
</div>
<button class="btn" type="button" id="deleteAcc">Delete</button>
My jQuery code is:
$("#deleteAcc").on("click",function(){
$(".control-group label.checkbox").each(function(){
if (this.children(":first").is(':checked')) {
this.remove();
}
});
});
You don't need each method. Just select the checked inputs and remove the parents (the label elements containing the checkboxes):
$("#deleteAcc").on("click", function() {
$(".checkbox input:checked").parent().remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="control-group">
<label class="checkbox">
<input value="0" type="checkbox">Message 0</label>
<label class="checkbox">
<input value="1" type="checkbox">Message 1</label>
<label class="checkbox">
<input value="2" type="checkbox">Message 2</label>
<label class="checkbox">
<input value="3" type="checkbox">Message 3</label>
<label class="checkbox">
<input value="4" type="checkbox">Message 4</label>
<label class="checkbox">
<input value="5" type="checkbox">Message 5</label>
<label class="checkbox">
<input value="6" type="checkbox">Message 6</label>
<label class="checkbox">
<input value="7" type="checkbox">Message 7</label>
<label class="checkbox">
<input value="8" type="checkbox">Message 8</label>
</div>
<button class="btn" type="button" id="deleteAcc">Delete</button>
The actual issue is that the this context in the $.each closure is a reference to the DOM node itself. One way you can fix this by wrapping this in $:
$("#deleteAcc").on("click",function(){
$(".control-group label.checkbox").each(function(){
if ($(this).children(":first").is(':checked')) {
$(this).remove();
}
});
});
Try this
http://jsfiddle.net/zp3vwh1j/2/
$("#deleteAcc").on("click",function(){
$("input:checkbox").each(function() {
if ($(this).is(":checked")) {
$(this).parent().remove();
}
});
});
$().ready(function () {
$('body').on('click', '#deletebtn', function () {
$("#example1 tr").each(function () {
var rowSelector = $(this);
if (rowSelector.find("input[type='checkbox']").prop('checked'))
{
//THE MARKUP SHOWING THE ID IS NOT AVAILABLE
//POST A TABLE ENTRY TO CLEAR UP
var id = rowSelector.find('td').first().next().html();
var sendObj = {Id : id};
//USE JSON OBJECT
$.ajax({
url : "/page.aspx/deleteRecord",//CHANGE TO YOUR URL
dataType: "json",
data: sendObj,
type: "POST",
success: function () {
alert("entry deleted");
}
});
rowSelector.remove();
}
});
});
});

We have many radio input.
function showReferal() {
document.querySelector('#referral_code').classList.remove('d-none');
}
<div class="form-group row d-none" id="referral_code">
<label for="referral_code">Referral Code</label>
<div class="col-md-10">
<input id="referral_code" type="text" class="form-control" name="referral_code">
</div>
</div>
<input class="form-check-input" type="radio" name="familiar" id="google" value="1">
<input class="form-check-input" type="radio" name="familiar" id="friends" value="2">
<input class="form-check-input" type="radio" name="familiar" id="advertising" value="3">
<input class="form-check-input" type="radio" name="familiar" id="marketer" value="4" onclick="showReferal()">
And when I click on #marketer should show #referral_code.
When I click on advertising and google and friends , referral_code must be hidden. only marketer be show
Similar to Alex Kudryashev's answer, but you can use the built-in toggle method instead of writing an if statement.
function showReferal(show) {
var refCode = document.querySelector('#referral_code');
refCode.classList.toggle('d-none', !show);
}
.d-none {
display: none
}
<div class="form-group row d-none" id="referral_code">
<label for="referral_code">Referral Code</label>
<div class="col-md-10">
<input id="referral_code" type="text" class="form-control" name="referral_code">
</div>
</div>
<input class="form-check-input" type="radio" name="familiar" id="google" value="1" onclick="showReferal(false)">
<input class="form-check-input" type="radio" name="familiar" id="friends" value="2" onclick="showReferal(false)">
<input class="form-check-input" type="radio" name="familiar" id="advertising" value="3" onclick="showReferal(false)">
<input class="form-check-input" type="radio" name="familiar" id="marketer" value="4" onclick="showReferal(true)">
You need to call the function from each radio button.
function showReferal(show) {
var refCode = document.querySelector('#referral_code');
if (show) {
refCode.classList.remove('d-none');
} else if (refCode.classList.value.indexOf('d-none') === -1) {
refCode.classList.add('d-none');
}
}
.d-none {
display: none
}
<div class="form-group row d-none" id="referral_code">
<label for="referral_code">Referral Code</label>

sorry for anyone who couldnt understand my question.
try this one
function fuelList(val) {
var val = parseInt(val);
if (val == 1) {
$('#FourWheeler').hide();
$('#TwoWheeler').show();
} else {
$('#TwoWheeler').hide();
$('#FourWheeler').show();
}
}

Here is what you can do easily with JQuery
$(document).ready(function(){
$("input[name='vehicleList']").click(function(){
var selectedValue = $(this).val();
if(selectedValue === "1"){
$('#TwoWheeler').show();
$('#FourWheeler').hide();
}else{
$('#TwoWheeler').hide();
$('#FourWheeler').show();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="OwnVehicle">
<label>
<input type="radio" name="vehicleList" id="two" value="1" />Two Wheeler
</label>
<label>
<input type="radio" name="vehicleList" id="four" value="2" />Four Wheeler
</label>
</div>
<div id="TwoWheeler" style="display:none">
<label>
<input type="radio" name="TwoWheeler" value="6" />Electric
</label>
<label>
<input type="radio" name="TwoWheeler" value="7" />Petrol
</label>
</div>
<div id="FourWheeler" style="display:none">
<label>
<input type="radio" name="FourWheeler" value="1" />Electric
</label>
<label>
<input type="radio" name="FourWheeler" value="2" />Petrol
</label>
<label>
<input type="radio" name="FourWheeler" value="3" />Diesel
</label>
<label>
<input type="radio" name="FourWheeler" value="4" />CNG
</label>
<label>
<input type="radio" name="FourWheeler" value="5" />LPG
</label>
</div>
Yiu can try this working code:
function fuelList(_this){
var value=$(_this).attr("value");
$("#TwoWheeler").hide();
$("#FourWheeler").hide();
if(value=="1"){
$("#TwoWheeler").show();
}
else if(value=="2"){
$("#FourWheeler").show();
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="OwnVehicle">
<label>
<input type="radio" name="vehicleList" id="two" onclick="fuelList(this)" value="1" />Two Wheeler
</label>
<label>
<input type="radio" name="vehicleList" id="four" onclick="fuelList(this)" value="2" />Four Wheeler
</label>
</div>
<div id="TwoWheeler" style="display:none">
<label>
<input type="radio" name="TwoWheeler" value="6" />Electric
</label>
<label>
<input type="radio" name="TwoWheeler" value="7" />Petrol
</label>
</div>
<div id="FourWheeler" style="display:none">
<label>
<input type="radio" name="FourWheeler" value="1" />Electric
</label>
<label>
<input type="radio" name="FourWheeler" value="2" />Petrol
</label>
<label>
<input type="radio" name="FourWheeler" value="3" />Diesel
</label>
<label>
<input type="radio" name="FourWheeler" value="4" />CNG
</label>
<label>
<input type="radio" name="FourWheeler" value="5" />LPG
</label>
</div>
Assuming I understood the question correctly, and you want to hide a div when you check a radio button?
Here is an example of how that can be achieved:
HTML:
<input type="radio" name="euResident" id="euResidentYes" value="Yes" checked />
<label for="euResidentYes" class="radio">yes</label>
<input type="radio" name="euResident" id="euResidentNo" value="No" />
<label for="euResidentNo" class="radio">no</label>
<div id='div'>Hello World</div>
Javascript:
function switchVar() {
if($("#euResidentNo").prop("checked"))
$("#div").show();
else
$("#div").hide();
}
$(document).ready(function() {
switchVar();
$("input[name=euResident]").change(switchVar);
});
It is an example using Javascript as this is perfect to use for this.
Demo: http://jsfiddle.net/2Uj9F/169/
Here you go with jsfiddle https://jsfiddle.net/ym10add9/
$("input[type='radio']").change(function() {
$('div').hide();
$( '#' + $(this).attr('value')).show();
});
My first suggestion is to change your onclick="" to onchange="".
<input type="radio" name="vehicleList" id="four" onchange="fuelList(this)" value="2" class="radioButtons" />Four Wheeler
<script>
function fuelList(element)
{
var id = element.value;
if( id == 1)
{
$(".wheels")hide(); //hides all the elements with class = wheels
$("#twoWheelers")show(); //shows the div with id = twoWheelers
}
else if( id == 2 )
{
$(".wheels")hide(); //hides all the elements with class = wheels
$("#fourWheelers")show(); //shows the div with id = fourWheelers
}
}
</script>
and put a class to the div of your "twoWheeler" and "fourWheeler"
I just make it "wheels"
<div id="twoWheelers" class="wheels">
...
</div>
<div id="fourWheelers" class="wheels">
...
</div>
I wrote code as per you describe in your post. May be useful to solve your problem.
$(document).ready(function() {
$('input[type=radio][name=vehicleList]').change(function() {
if (this.value == '1') {
$("#FourWheeler").hide();
$("#TwoWheeler").show();
}
else if (this.value == '2') {
$("#FourWheeler").show();
$("#TwoWheeler").hide();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="vehicleList">
<label>
<input type="radio" name="vehicleList" id="two" value="1" />Two Wheeler
</label>
<label>
<input type="radio" name="vehicleList" id="four" value="2" />Four Wheeler
</label>
</div>
<h5>Output : </h5>
<div id="TwoWheeler" style="display:none">
<label>
<input type="radio" name="TwoWheeler" value="6" />Electric
</label>
<label>
<input type="radio" name="TwoWheeler" value="7" />Petrol
</label>
</div>
<div id="FourWheeler" style="display:none">
<label>
<input type="radio" name="FourWheeler" value="1" />Electric
</label>
<label>
<input type="radio" name="FourWheeler" value="2" />Petrol
</label>
<label>
<input type="radio" name="FourWheeler" value="3" />Diesel
</label>
<label>
<input type="radio" name="FourWheeler" value="4" />CNG
</label>
<label>
<input type="radio" name="FourWheeler" value="5" />LPG
</label>
</div>
Below is simple JQuery code that will help you to achieve your requirement:
$("input[name='vehicleList']").on('click', function() {
if ($(this).val() == 1) {
$('#TwoWheeler').show();
$('#FourWheeler').hide();
} else {
$('#TwoWheeler').hide();
$('#FourWheeler').show();
}
});
#TwoWheeler,
#FourWheeler {
display: none;
}
#OwnVehicle label,
#TwoWheeler label,
#FourWheeler label {
cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="OwnVehicle">
<label>
<input type="radio" name="vehicleList" id="two" value="1" />Two Wheeler
</label>
<label>
<input type="radio" name="vehicleList" id="four" value="2" />Four Wheeler
</label>
</div>
<div id="TwoWheeler">
<label>
<input type="radio" name="TwoWheeler" value="6" />Electric
</label>
<label>
<input type="radio" name="TwoWheeler" value="7" />Petrol
</label>
</div>
<div id="FourWheeler">
<label>
<input type="radio" name="FourWheeler" value="1" />Electric
</label>
<label>
<input type="radio" name="FourWheeler" value="2" />Petrol
</label>
<label>
<input type="radio" name="FourWheeler" value="3" />Diesel
</label>
<label>
<input type="radio" name="FourWheeler" value="4" />CNG
</label>
<label>
<input type="radio" name="FourWheeler" value="5" />LPG
</label>
</div>
This is one way to do it:
$( "#r0" ).bind( "click", function() {
$("#OwnVehicle").show();
$("#TwoWheeler").hide();
});
$( "#r1" ).bind( "click", function() {
$("#OwnVehicle").hide();
$("#TwoWheeler").show();
});
Here a working fiddle

It can be improved
I have this script. Everything is working except I need to make it work with multi-able items. The first set of work perfectly, but I can seam to replicate it on the second and third set of check boxes.
$(".checkall").on('change', function()
{
// all normal checkboxes will have a class "chk_xxxxxx"
// where "xxxx" is the name of the location, e.g. "chk_wales"
// get the class name from the id of the "check all" box
var checkboxesClass = '.chk_' + $(this).attr("id");
// now get all boxes to check
var boxesToCheck = $(checkboxesClass);
// check all the boxes
boxesToCheck.prop('checked', this.checked);
});
$("#check1 input[type=checkbox], #wales").on("change", function()
{
checkBoxes();
});
function checkBoxes()
{
$("#checked").empty();
if($("#check1 input[type=checkbox]:checked").length == $("#check1 input[type=checkbox]").length)
{
$("#wales").prop("checked", true);
// Display the id of the "check all" box
$("#checked").html($("#checked").html() + "<h3>Wales</h3>");
}
else
{
$("#wales").prop("checked", false);
$("#check1 input[type=checkbox]:checked").each(function()
{
$("#checked").html($("#checked").html() + $(this).next().text() + "<br>");
});
}
}

Many thanks in advance.
remove checkBoxes() method and replace the last event handlers as (check this fiddle)
//put the event handler directly on the checkboxes inside the section
$( "section input[type='checkbox']" ).on("change", function()
{
console.log( $( this ) );
//get the handle to the parent section
var $parentSection = $( this ).parent();
//compare the number of checked checkboxes with total one
if( $parentSection.find( "input[type='checkbox']:checked" ).length == $parentSection.find( "input[type=checkbox]" ).length )
{
$parentSection.prev().prev().prop("checked", true);
//write checkall's textbox id
$("#checked").append( "<h3>" + $parentSection.prev().prev().attr( "id" ) + "</h3>");
}
else
{
$parentSection.prev().prev().prop("checked", false);
//write each and every checked box's text
$parentSection.find("input[type='checkbox']:checked").each(function()
{
$("#checked").html($("#checked").html() + $(this).next().text() + "<br>");
});
}
});
Following code snippet should fulfill your requirements. Hope this will help you.

I’m having some problems with some JavaScript I created. When a item from check all is Unchecked it needs to remove the checked from the checked all box, also when the check all is checked I don’t want to to pull through the other items only the check all box.
check all, item 1, item 2
Remove item 1 and check all un-checks and all that gets pulled through is item. If check all is checked the item 1 and item 2 are checked but then not pulled through.
// all "check all" checkboxes will have the class "checkall"
// and the id to match the location, e.g. wales, etc
$(".checkall").on('change', function() {
// all normal checkboxes will have a class "chk_xxxxxx"
// where "xxxx" is the name of the location, e.g. "chk_wales"
// get the class name from the id of the "check all" box
var checkboxesClass = '.chk_' + $(this).attr("id");
// now get all boxes to check
var boxesToCheck = $(checkboxesClass);
// check all the boxes
boxesToCheck.prop('checked', this.checked);
});
// display what the user has chosen
$("input[type='checkbox']").change(function() {
$("#checked").empty();
$("input[type='checkbox']:checked").each(function() {
// see if it is a "check all" box

// With some more work you could make the Check All headings show when only one or two checkboxes were checked. It depends how you need it to work.

Not sure what you mean by 'pulled through', but unchecking the check-all can be achieved through:
if (!$currentCheckbox.hasClass('checkall')) {
var $previousCheckAll = $currentCheckbox.prevAll('.checkall');
if ($previousCheckAll.length>0)
{
$previousCheckAll.first().prop('checked',false);
}
}
Just insert the code above beneath the line
$("#checked").empty();
of your JSbin.
This code should work if im not mistaken what you are trying to say. I have done for first set of checkboxes. You can do it for next two:
$("#check1 input[type=checkbox]").on("change", function() {
if($("#check1 input[type=checkbox]:checked").length == $("#check1 input[type=checkbox]").length) {
$("#wales").prop("checked",true);
}
else {
$("#wales").prop("checked",false);
}
});

<input type="checkbox" id="wales" class="checkall" value="1">
<label for="wales">Check All</label>

<label for="checkItem2">Item 2</label>
<input type="checkbox" id="checkItem3" value="2" class="chk_wales">

</section>
UPDATE
This will fulfill your requirement. Remove your $("input[type='checkbox']").change(function() code and use the updated one
$("#check1 input[type=checkbox]").on("change", function()
{
$("#checked").empty();
if($("#check1 input[type=checkbox]:checked").length == $("#check1 input[type=checkbox]").length)
{
$("#wales").prop("checked", true);
// Display the id of the "check all" box
$("#checked").html($("#checked").html() + "<h3>Wales</h3>");
}
else
{
$("#wales").prop("checked", false);
$("#check1 input[type=checkbox]:checked").each(function()
{
$("#checked").html($("#checked").html() + $(this).next().text() + "<br>");
});
}
});

Another Update
$(".checkall").on('change', function()
{
// all normal checkboxes will have a class "chk_xxxxxx"
// where "xxxx" is the name of the location, e.g. "chk_wales"
// get the class name from the id of the "check all" box
var checkboxesClass = '.chk_' + $(this).attr("id");
// now get all boxes to check
var boxesToCheck = $(checkboxesClass);
// check all the boxes
boxesToCheck.prop('checked', this.checked);
});
$("#check1 input[type=checkbox], #wales").on("change", function()
{
checkBoxes();
});
function checkBoxes()
{
$("#checked").empty();
if($("#check1 input[type=checkbox]:checked").length == $("#check1 input[type=checkbox]").length)
{
$("#wales").prop("checked", true);
// Display the id of the "check all" box
$("#checked").html($("#checked").html() + "<h3>Wales</h3>");
}
else
{
$("#wales").prop("checked", false);
$("#check1 input[type=checkbox]:checked").each(function()
{
$("#checked").html($("#checked").html() + $(this).next().text() + "<br>");
});

I got trouble finding a solution to this one.
I have an amount of checkboxes, and I want to get how many of them are checked.
Each time a box get checked/unchecked, the value needs to update.
What I have so far:
http://jsfiddle.net/drhmorw5/3/
My code so far:
function selected() {
var i = 0;
$("#names").each(function () {
if ($(this).prop("checked") === true) {
i++;
$("#checked").text("Sum Checked: " + i);
}
})
};
$("#checked").text("Sum Checked: ");
$(function(){
$('#names input[type=checkbox]').change(function(){
$("#checked").text($('#names input[type=checkbox]:checked').length);
});
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<div id="names">
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 1</label>
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 2</label>
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 3</label>
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 4</label>
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 5</label>
<label>
<input type="checkbox" name="checkbox-0" class="check">Name 6</label>
</div>
<br>
<br>
Sum Checked: <span id="checked">0</span>
