So I have 10 checkbox fields, more then 1 can be selected, but at least 1 has to be selected at a minimum.
I had it working use the name="" attribute but that was not the case anymore as the name has to be unique to integrate with our CRM.
So I added the rule to use the class instead using addClassRule() and I added my own method to use a custom message for required.
But the result is they are all required. regardless if 1 or more is selected?
Here is my jQuery which is working but it requires all 10 checkbox's to be checked.
$.validator.addMethod("checkboxRequired", $.validator.methods.required, "Please select at least 1 of the values");
jQuery.validator.addClassRules('checkbox-validate', {
checkboxRequired: true
});
HTML code:
<div id="id_1" class="form-input">
<label for="test1"><input class="checkbox-validate" type="checkbox" id="test1" name="test1" value="1">1</label>
<label for="test2"><input class="checkbox-validate" type="checkbox" id="test2" name="test2" value="2">2</label>
<label for="test3"><input class="checkbox-validate" type="checkbox" id="test3" name="test3" value="3">3</label>
<label for="test4"><input class="checkbox-validate" type="checkbox" id="test4" name="test4" value="4">4</label>
<label for="test5"><input class="checkbox-validate" type="checkbox" id="test5" name="test5" value="5">5</label>
<label for="test6"><input class="checkbox-validate" type="checkbox" id="test6" name="test6" value="6">6</label>
<label for="test7"><input class="checkbox-validate" type="checkbox" id="test7" name="test7" value="7">7</label>
<label for="test8"><input class="checkbox-validate" type="checkbox" id="test8" name="test8" value="8">8</label>
<label for="test9"><input class="checkbox-validate" type="checkbox" id="test9" name="test9" value="9">9</label>
<label for="test10"><input class="checkbox-validate" type="checkbox" id="test10" name="test10" value="10">10</label>
</div>
Try require_from_group-method rule
jQuery(function($) {
jQuery.validator.addClassRules('checkbox-validate', {
require_from_group: [1, ".checkbox-validate"]
});
var validator = $('#myform').validate({
rules: {},
messages: {},
errorPlacement: function(error, element) {
if (element.hasClass('checkbox-validate')) {
element.closest('.form-input').find('.error-holder').html(error)
} else {
error.insertAfter(element);

You need to make your name attribute all be the same value. Then you can check how many are checked like so:
var count = $('input[name=test]:checked').size();

I am making a form with 10 fields with 10 checkboxes. On updating the field i want relevant checkbox to be checked. I can make it work by writing 10 different ON change function but i am looking for a smart way to achieve it instead of writing 10 different ON change functions for respective fields.
<input value="1" name="checkbox-1" id="checkbox-1" type="checkbox"/>
<label for="checkbox-1"></label>
<input type="text" value="" id="field-1" name="field-1">
<label class="form-label">Field 1</label>
<input value="1" name="checkbox-2" id="checkbox-2" type="checkbox"/>
<label for="checkbox-2"></label>
<input type="text" value="" id="field-2" name="field-2">
<label class="form-label">Field 2</label>
<input value="1" name="checkbox-3" id="checkbox-3" type="checkbox"/>
<label for="checkbox-3"></label>
<input type="text" value="" id="field-3" name="field-3">
<label class="form-label">Field 3</label>
$('#field-1').bind('change', () => {
$('#checkbox-1').prop('checked', true);
});
$('#field-2').bind('change', () => {
$('#checkbox-2').prop('checked', true);
});
$('#field-3').bind('change', () => {
$('#checkbox-3').prop('checked', true);
});
I would advise you to use starts-with selector to find all your fields and bind input handlers. Then when you are able to handle it, you have to find appropriate checkbox and check it:
$('input[name^="field-"]').on('input', function(){
let fieldId = $(this).attr('name').slice(-1);
$('#checkbox-'+fieldId).prop('checked', true);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input value="1" name="checkbox-1" id="checkbox-1" type="checkbox"/>
<label for="checkbox-1"></label>
<input type="text" value="" id="field-1" name="field-1">
<label class="form-label">Field 1</label>
<input value="1" name="checkbox-2" id="checkbox-2" type="checkbox"/>
<label for="checkbox-2"></label>
<input type="text" value="" id="field-2" name="field-2">
<label class="form-label">Field 2</label>
<input value="1" name="checkbox-3" id="checkbox-3" type="checkbox"/>
<label for="checkbox-3"></label>
<input type="text" value="" id="field-3" name="field-3">
<label class="form-label">Field 3</label>
Wrap your iinput field and checkbox in a div and then add the logic of checking your checkbox to those wrappers.
$('.checked-input').find('input[type=text]').on('change', function(){
$(this).closest('.checked-input').find('input[type=checkbox]').prop('checked', true);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="checked-input">
<input type="text" value="" id="field-1" name="field-1">
<input value="1" name="checkbox-1" id="checkbox-1" type="checkbox"/>
</div>
<div class="checked-input">
<input type="text" value="" id="field-2" name="field-2">
<input value="1" name="checkbox-2" id="checkbox-2" type="checkbox"/>
</div>
You could group all input which contain field in their id and use the number id to check corresponding checkbox:
$('input[id*=field]').on('change', function() {
$('#checkbox-' + $(this).prop("id").split('-')[1]).prop('checked', true);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input value="1" name="checkbox-1" id="checkbox-1" type="checkbox" />
<label for="checkbox-1"></label>
<input type="text" value="" id="field-1" name="field-1">
<label class="form-label">Field 1</label>
<input value="1" name="checkbox-2" id="checkbox-2" type="checkbox" />
<label for="checkbox-2"></label>
<input type="text" value="" id="field-2" name="field-2">
<label class="form-label">Field 2</label>
<input value="1" name="checkbox-3" id="checkbox-3" type="checkbox" />
<label for="checkbox-3"></label>
<input type="text" value="" id="field-3" name="field-3">
<label class="form-label">Field 3</label>
As an alternative you could tell the input which checkbox to target using a data poperty. I also put an alternate to only check if not empty OR an alternate to find the prior sibling of each.
$('input[type=text]').on('change', function(event) {
let checkpair = $(this).data('targetpair');
$(checkpair).prop('checked', true);
// alternate only if not empty:
//$(checkpair).prop('checked', $(this).val().trim().length);
});
/* alternate that finds the immediate checkbox sibling
$('input[type=text]').on('change', function(event) {
$(this).prevAll('input[type=checkbox]').first().prop('checked', true);
});
*/
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<input value="1" name="checkbox-1" id="checkbox-1" type="checkbox" />

Your current logic is only reading the value of the last clicked checkbox. Instead you can use map() to build an array of all the checked values, then join() the resulting array together as a string to be displayed, something like this:
$(':checkbox').on('change', function() {
var values = $(':checkbox:checked').map(function() {
return this.value;
}).get().join(', ');
$('#cs-input').html(values);
});

<div id="cs-input"></div>

Note the use of the :checkbox selector over [type="checkbox"] and :checked within the handler to retrieve only those which have been chosen.
Also note the addition of label elements to make the hit area of each checkbox include the text next to it.
I have a multi-step form that has a "next" and "back" button on each step of the form. I'm using jQuery to enable the "next" button once the criteria for each section is met. For example: at least one checkbox is checked or a radio button is selected.
I'm having an issue where after completing a number of sections, I go back to a previous section and uncheck all checkboxes and the "next" button remains enabled.
There's a Codepen here of a rough version of what I'm working with - note all sections are visible to show how the button remains enabled once you begin checking/unchecking: https://codepen.io/abbasarezoo/pen/jZgQOV

JS:
var $panelsInput = $('.panels input'),
$rowsInput = $('.rows input');
$panelsInput.click(function () {
if ($('.panels input:checked').length >= 1) {
$(this).closest('.panels').find('.next-q').prop('disabled', false);
}
else {
$(this).closest('.panels').find('.next-q').prop('disabled', true);

$rowsInput.click(function () {

if ($('.rows input:checked').length == radioLength) {
$('.rows .next-q').prop('disabled', false);
}
else {
$('.rows .next-q').prop('disabled', true);
}
});
Is there any way to make this work?
when you select the input to see if is checked, you're selecting all inputs
if ($('.panels input:checked').length >= 1) {
you need to select just the inputs from the panel the user clicked
if ($(this).closest('.panels').find('input:checked').length >= 1) {
https://codepen.io/spacedog4/pen/YaWqdo?editors=1010
Please see below comment in $panelsInput.click(function (){});, you need to get the checked count for current panel (the user clicks), instead of all.
So the comparasion in your codes:
$('.panels input:checked').length >= 1
need to change to:
$(this).parent().find('input:checked').length >= 1
var $panelsInput = $('.panels input'),
$rowsInput = $('.rows input');
$panelsInput.click(function () {
//get current input, find out its parent, then get the count of checked
if ($(this).parent().find('input:checked').length >= 1) {
$(this).closest('.panels').find('.next-q').prop('disabled', false);
}
else {
$(this).closest('.panels').find('.next-q').prop('disabled', true);
}
});
$rowsInput.click(function () {
var radioLength = $('.radio-row').length;
if ($('.rows input:checked').length == radioLength) {
$('.rows .next-q').prop('disabled', false);
}
else {
$('.rows .next-q').prop('disabled', true);

I thought it is interesting to handle interactions using event delegation at the form level which is more flexible:
Only one handler is loaded in memory. (By the way only a single scope is in charge of the logic behind the prev/next behavior).
You can add dynamically panels to the form (with the same markup structure) and buttons will work right away without requiring another listener registering step.
var $panelsInput = $('.panels input')
, $rowsInput = $('.rows input')
;
$('form').on('click', function (e) {
let $t = $(this)
, $target = $(e.target)
, $fieldset = $target.closest('fieldset')
, $rows = $fieldset.find('.radio-row')
;
// When a button is clicked
if ($target.is('button')) {
// Next button
if ($target.is('.next-q')) {
$fieldset.addClass('hide').next().addClass('show');
// Prev button
} else {
// Untick boxes
$fieldset.find('input').prop('checked', false).end()
// Disable appropriate button
.find('.next-q').prop('disabled', true).end()
.prev().removeClass('hide').nextAll().removeClass('show');
}
// When a checkbox is clicked
} else if ($target.is('input')) {
let $containers = ($rows.length ? $rows : $fieldset)
, containersHavingAtickedBox = $containers.filter(function() {
return !!$(this).find('input:checked').length
})
, shouldEnable = $containers.length === containersHavingAtickedBox.length
;
$fieldset.find('.next-q').prop('disabled', !shouldEnable);
}
});

I'm a newbie coder and cannot for the life of me figure out how to add up values for radio buttons below - any help would be greatly appreciated!
I am trying to create a diabetes screening assessment tool - where you will be able to assign different values to different risk factors.
You would need to use JavaScript to accomplish this.
Here's one way to do it:
Listen for the form's submit event
Prevent the default (so that the form doesn't get sent to the server)
Grab the value from each field. Fields use the name attribute from the HTML
Use parseInt on each field because they'll be strings
Add them up
Display the result (in this example, in the console)
const form = document.querySelector('form')
form.addEventListener('submit', event => {
event.preventDefault()
const total =
parseInt(form.age.value) +
parseInt(form.bmi.value) +
parseInt(form.famhistory.value) +
parseInt(form.diet.value)
console.log(total)
})

If you plan on adding values, here is a more flexible approach.
The idea is to loop through each relevant input (those that are inside your fieldset with ID controls), regardless of its name, so that if you add more checks, the same code will still work.
Create a score variable and increment it with the value of each input that is checked.
Be careful, you have the value 0 TWICE for the BMI check
window.addEventListener('DOMContentLoaded', function() {
var form = document.querySelector('form');
form.addEventListener('submit', function(event) {
event.preventDefault();
var inputs = document.querySelectorAll('#controls input');
var score = 0;
inputs.forEach(function(input) {
if (input.checked) {
score += parseInt(input.value, 10);
}
});
console.log(score);
});
});

i have a group of check boxes and i want to use a check all function but only for the corresponding checkboxes for example if i click checkAll1 it will only highlight checkItem 1 but also will still allow me to check other check boxes.
you will see from the snippet below the code i currently have, i want to also be able to put the checkAll label when it comes out to the #check div to be in a p tag so i can style it.
hope this all makes sense
Many thanks
$("input[type='checkbox']").change(function(){
$("#checked").empty();
$("input[type='checkbox']:checked").each(function(){
$("#checked").html($("#checked").html() + $(this).next().text() + " ");
});
});

You can use value to call checkbox, Do something like this..
var chk1 = $("input[type='checkbox'][value='1']");
var chk2 = $("input[type='checkbox'][value='2']");
var chk3 = $("input[type='checkbox'][value='3']");
var chk4 = $("input[type='checkbox'][value='4']");
var chk5 = $("input[type='checkbox'][value='5']");
var chk6 = $("input[type='checkbox'][value='6']");
chk1.on('change', function(){
chk2.prop('checked',this.checked);
});
chk3.on('change', function(){
chk4.prop('checked',this.checked);
});
chk5.on('change', function(){
chk6.prop('checked',this.checked);
});
$("input[type='checkbox']").change(function(){
$("#checked").empty();
$("input[type='checkbox']:checked").each(function(){
$("#checked").html($("#checked").html() + $(this).next().text() + "<p></p>");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" id="checkAll1" value="1"><label for="checkAll1" >Check All</label>
<input type="checkbox" id="checkItem1" value="2"> <label for="checkItem1" >Item 1</label>
<input type="checkbox" id="checkItem1" value="2"><label for="checkItem1" >Item 2</label>
<input type="checkbox" id="checkItem1" value="2"><label for="checkItem1" >Item3</label>
<hr />
<input type="checkbox" id="checkAll2" value="3"> <label for="checkAll2">Check All</label>
<input type="checkbox" id="checkItem2" value="4"><label for="checkItem2">Item 1</label>
<input type="checkbox" id="checkItem2" value="4"><label for="checkItem2">Item 2</label>
<input type="checkbox" id="checkItem2" value="4"><label for="checkItem2">Item3</label>
<hr />
<input type="checkbox" id="checkAll3" value="5"><label for="checkAll3">Check All</label>
<input type="checkbox" id="checkItem3" value="6"><label for="checkItem3">Item 1</label>
<input type="checkbox" id="checkItem3" value="6"> <label for="checkItem3">Item 2</label>
<input type="checkbox" id="checkItem3" value="6"><label for="checkItem3">Item3</label>

I tweak your code a little, and what you mean by able to put the checkAll label when it comes out to the #check div which i did't get it, try this below code :
$("input[type='checkbox']").change(function() {
$("#checked").empty();
$("input[type='checkbox']:checked").each(function() {
$("#checked").html($("#checked").html() + $(this).next().text() + " ");
});
});
$(".checkAll").click(function() {
if ( $(this).is(':checked') )
$(this).siblings(':checkbox').prop('checked', true);
else
$(this).siblings(':checkbox').prop('checked', false);
});
<div>
<!-- add class="checkAll" for checkAll checkbox only -->
<input type="checkbox" id="checkAll1" class="checkAll">
<label for="checkAll1">Check All</label>
<input type="checkbox" id="checkItem1">
<label for="checkItem1">Item 1</label>
<input type="checkbox" id="checkItem1">
<label for="checkItem1">Item 2</label>
<input type="checkbox" id="checkItem1">

<p>You have selected:</p>
<div id="checked"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
p/s : like other said, id must be unique for elements
Assign a same class for the same row check boxes
Use the below jquery
$("#checkAll1").change(function(){
$(".checkItem1").prop("checked", true);
});
$("#checkAll2").change(function(){
$(".checkItem2").prop("checked", true);
});
$("#checkAll3").change(function(){

});
