How can I check with JQuery if a checkbox is checked and if so add a class to the parent label?

I would like, on load of the page, to check if a checkbox is :checked Then if it is, add a class to the label. I currently have the following script but it doesn't work.
$(document).ready(function() {
$('input').is(':checked') {
$(this).parent('label').toggleClass('label--active');
});
});
My HTML is:
<label class="container-checkbox" for="checkOne">
<span class="checkbox-label">Option one</span>
<input type="checkbox" id="checkOne">
<span class="checkmark"></span>
</label>
I can not change the DOM order as these are custom checkboxes.

I guess you can use this:
$(document).ready(function() {
let checkboxone = document.getElementById('checkOne');
checkboxone.addEventListener('change',function() {
checkboxone.parentNode.classList.toggle('label--active');
});
});
How does is work?
Everytime when the checkbox is clicked, the class 'label--active' will be added / removed.

jQuery Select All Checkbox with toggleClass

I have seen other examples of this but have not successfully gotten this to function correctly. The examples I have seen also are just using regular checkboxes. I have used a class to stylize the checkbox with a sprite sheet so having a bit of trouble taking the ideas of these other examples and applying them to my case.
Here is the mark up:
<div id="showHideAll"">Show/Hide All<input type="checkbox" id="allCheck" name="pinSet" class="pinToggles" onclick="checkAllLinks()">
<label for="allCheck" class="css-label"></label></div>
</div>
<div>Opt1<input type="checkbox" id="opt1Check" name="pinSet" class="pinToggles" onclick="checkOpt1Links()">
<label for="opt1Check" class="css-label"></label>
</div>
<div>Opt2<input type="checkbox" id="opt2Check" name="pinSet" class="pinToggles" onclick="checkOpt2Links()">
<label for="opt2Check" class="css-label"></label>
</div>
<div>Opt3<input type="checkbox" id="opt3Check" name="pinSet" class="pinToggles" onclick="checkOpt3Links()">
<label for="dinShopCheck" class="css-label"></label>
</div>
The checked property is what changes the sprite using a css class.
input[type=checkbox].pinToggles:checked + label.css-label {
background-position: 0 -16px;
}
Most of this is for other functionality but thought I would show it just in case.
This is how I set up the individual checkboxes:
function checkOpt1Links(){
$('#opt1 li a').toggleClass("inactive");
if(opt1.getVisible() == true)
{
opt1.setOptions({visible:false});
}
else
{
opt1.setOptions({visible:true});
}
}
What I am looking for is the typical select all checkbox functionality, where if you check it the boxes all check, if you uncheck they all uncheck but also if you click a box when select all is checked the select all and the clicked checkbox uncheck and vice versa. I did look at this example: Jquery "select all" checkbox but just having difficult time making it work. Thanks for the help!

1) Use change event handler instead of click for checkbox and radio buttons.
You can make it simple like this
$('#showHideAll').on('change', 'input[type=checkbox]', function () {
if ($('.pinToggles').is(':checked')) {
$('.pinToggles').prop('checked', false)
}
else {
$('.pinToggles').prop('checked', true)
}
});
2) I have removed the class and onclick event handler in the below checkbox only.
HTML:
<div id="showHideAll">Show/Hide All<input type="checkbox" id="allCheck" name="pinSet" >
<label for="allCheck" class="css-label"></label></div>
</div>

CheckAll/UncheckAll checkbox with jQuery

I have made a check-box checkall/uncheckall.
HTML
<div> Using Check all function </div>
<div id="selectCheckBox">
<input type="checkbox" class="all" onchange="checkAll('selectCheckBox','all','check','true');" />Select All
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 1
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 2
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 3
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 4
</div>
main.js
function checkAll(parentId,allClass,checkboxClass,allChecked){
checkboxAll = $('#'+parentId+' .'+allClass);
otherCheckBox = $('#'+parentId+' .'+checkboxClass);
checkedCheckBox = otherCheckBox.filter($('input[type=checkbox]:checked'));
if(allChecked=='false'){
if(otherCheckBox.size()==checkedCheckBox.size()){
checkboxAll.attr('checked',true);
}else{
checkboxAll.attr('checked',false);
}
}else{
if(checkboxAll.attr('checked')){
otherCheckBox.attr('checked',true);
}else{
otherCheckBox.attr('checked',false);
}
}
}
It works fine. But get bulky when I have whole lot of checkboxes. I want to do same work by using jQuery rather than putting onchange on each checkbox. I tried different sort of things but couldnot work. I tried following one:
$('.check input[type="checkbox"]').change(function(e){
checkAll('selectCheckBox','all','check','true');
});
to do same work as onchange event but didnot work. Where do I went wrong.

I think you just need this: You do not need to pass all the arguments and have the inline onchange event attached to it. You can simplify your code.
$(function () {
$('input[type="checkbox"]').change(function (e) {
if(this.className == 'all')
{
$('.check').prop('checked', this.checked); //Toggle all checkboxes based on `.all` check box check status
}
else
{
$('.all').prop('checked', $('.check:checked').length == $('.check').length); // toggle all check box based on whether all others are checked or not.
}
});
});
Demo

Your selector is wrong:
.check input[type="checkbox"]
Above selects any input of type checkbox that has the ancestor with class .check. It'll match this:
<div class="check">
<input type="checkbox".../>
</div>
it should be:
input.check[type="checkbox"]

You closed the string here $('.check input[type='checkbox']') instead, you should use double quotes $('.check input[type="checkbox"]')

problem with jquery for add cart button

hi i have a problem with displaying amount.i have the page called make payment in this page i made three radio buttons, if i click the button that amount must add with addcart like a product.

$(".cart :radio[name='rmr']").add(".cart :radio[name='rmr']").each(function() {
$(this).click(function() {
$(".cart :radio[name='rmr']").add(".cart :radio[name='rmr']").each(function() {
$(this).attr("checked", false);
});
$(this).attr("checked", true);
});
});
})
function updatePayment(val) {
$("<p/>").html("updatePayment(" + val + ")").appendTo(document.body);
}
thanks.have a nice day

I have no idea why you seem to be implementing the selecting and un-selecting of radio buttons in jQuery, surely HTML will handle that correctly for you.
However if you are using jQuery, do away with those onclick attributes since that is the benefit of jQuery and achieve the same result as follows:
$(function() {
$('.cart :radio[name="rmr"]').change(function() {
if ($(this).is(':checked'))
updatePayment(this.value);
});
});
This will attach a change event to every radio button input with the attribute name="rmr". Thus when the client clicks a new radio button, the value of two radio buttons will change, and the one that is then selected will call the updatePayment function with its value.

Uncheck all other checkboxes

I need to clear all other checkboxes when a user clicks a checkbox. Pretty much the same behavior as a radio button. User clicks checkbox 'A' and checkboxes 'B' and 'C' are both unchecked. I am using jquery but I can't figure out how to accomplish this. Any ideas?
Here are how the checkboxes are set u:
<div class="sales_block_one">
<span class="sales_box_option_set"><input type="checkbox" value="1" id="exopt10i11553501716" name="optset[0][id]" /><label for="exopt10i11553501716">Test + £100.00</label></span>
<span class="sales_box_option_set"><input type="checkbox" value="2" id="exopt11i21553501716" name="optset[1][id]" /><label for="exopt11i21553501716">Test + £ 200.00</label></span>
<span class="sales_box_option_set"><input type="checkbox" value="3" id="exopt12i31553501716" name="optset[2][id]" /><label for="exopt12i31553501716">Test 3 + £400.00</label></span>
</div>

if all the checkboxes are siblings, it's just like this,
$(':checkbox').change(function(){
if (this.checked) {
$(this).siblings(':checkbox').attr('checked',false);
}
});
crazy demo
Well, if you really want to copy the behavior of the radio button, simple as this,
$(':checkbox').change(function(){
this.checked = true;
$(this).siblings(':checkbox').attr('checked',false);
});
crazy demo
siblings is when the elements has one same parent/container.
sample
<div>
<input type="checkbox" /><label>A</label>
<input type="checkbox" /><label>B</label>
<input type="checkbox" /><label>C</label>
<input type="checkbox" />​<label>D</label>
</div>
in that, <input>s and <label>s are siblings.
In your case, which it's not siblings, you can do it this way,
$('.sales_block_one :checkbox').change(function() {
var $self = this; // save the current object - checkbox that was clicked.
$self.checked = true; // make the clicked checkbox checked no matter what.
$($self).closest('span') // find the closest parent span...
.siblings('span.sales_box_option_set') // get the siblings of the span
.find(':checkbox').attr('checked',false); // then find the checbox inside each span and then uncheck it.
});​
crazy demo
more about traversing

$("#checkboxA").click(function() {
var checkedStatus = this.checked;
$("#checkboxB_And_C_Selector").each(function() {
this.checked = !checkedStatus;
});
});
