I am wanting to loop over an checkbox input and check if the checkbox ISNT selected then add the value of the checkbox to an array which im wanting to POST through ajax.
I have an example below of looping through checkboxes which are selected but how would i do the inverse of this while still including the .each?
var categories = [];
$("input[name='categories[]']:checked").each(function () {
categories.push(this.value);
});
You mean this?
$("input[name='categories[]']").each(function () {
if (!this.checked) categories.push(this.value);
});
or
const categories = $("input[name='categories[]']").not(":checked") // or ]:not(:checked)")
.map(function() { return this.value })
.get();
console.log(categories)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="categories[]" value="1" checked />
<input type="checkbox" name="categories[]" value="2" />
<input type="checkbox" name="categories[]" value="3" checked />

hope you can help me :)
I have this code to get the value of the checkboxes:
function check() {
var Input = Array.prototype.slice.call(document.querySelectorAll(".checkboxes:checked")).map(function(el) {
return el.value;
}).join(',')
document.getElementById('output2').innerHTML = Input;
return false;
}
I want that the output is in the order I selected the checkboxes. Is there a way to get them in correct order?
You can set the timestamp to them when they are changed (comments inline)
var allCheckboxes = document.querySelectorAll("input[type='checkbox'][data-name]");
//bind the event to set time value on change
[...allCheckboxes].forEach(s => s.addEventListener("change", function(e) {
e.currentTarget.timeval = new Date().getTime();
}));
document.querySelector("button").addEventListener("click", check);
function check() {
var output = [...allCheckboxes]
.filter(s => s.checked) // filter out non-checked
.sort((a, b) => a.timeval - b.timeval) //sort by timeval
.map(s => s.getAttribute("data-name")).join(","); //fetch only data-name for display
document.getElementById('output').innerHTML = output;
}
Check 1 <input type="checkbox" data-name="check1"> <br/> Check 2 <input type="checkbox" data-name="check2"> <br/> Check 3 <input type="checkbox" data-name="check3"> <br/> Check 4 <input type="checkbox" data-name="check4"> <br/> Check 5 <input type="checkbox"
data-name="check5"> <br/>
<button>check</button>
<div id="output"></div>
You can set an array and save the values as they are selected.
You can achive this by giving each chcekbox an event listener.
In the event listener you add an if to validate if the click event was when checked and then add them to your list/array.
Hope this helps :)
var checks = document.querySelectorAll('input[type=checkbox]');
var order = [];
for(var i=0; i<checks.length;i++){
checks[i].addEventListener("click", function(){
if(this.checked)
order.push(this.value);
})
}
<input type="checkbox" value="A">A
<input type="checkbox" value="B">B
<input type="checkbox" value="C">C
<input type="checkbox" value="D">D
<br>
<button onclick="console.log('Order: '+order)">Check order</button>
You can add a data-id attribute to each section. And when you click on one checkbox, change the attribute values of each checkbox to a serial number. To do this, it's easier to use jquery
You could use a Set and add or delete depending of the checked state of the check box.
Set returns the items in insertation order.
var checks = document.querySelectorAll('input[type=checkbox]'),
order = new Set,
i
for (i = 0; i < checks.length; i++) {
checks[i].addEventListener("click", function() {
order[['delete', 'add'][+this.checked]](this.value);
});
}
<input type="checkbox" value="A">A
<input type="checkbox" value="B">B
<input type="checkbox" value="C">C
<input type="checkbox" value="D">D
<br>
<button onclick="console.log('Order: '+[...order])">Check order</button>
I have a list of checkboxes like so:
<div class="checkbox-list">
<label><input type="checkbox" value="" /> All items</label><br />
<label><input type="checkbox" value="1" /> First item</label><br />
<label><input type="checkbox" value="2" /> Second item</label><br />
<label><input type="checkbox" value="3" /> Third item</label><br />
<label><input type="checkbox" value="4" /> Forth Checkbox</label>
</div>
The behavior I am looking for is if I select the first checkbox in this div (.checkbox-list input[type=checkbox]:first) all other checkboxes after is checked off. Likewise if I select any other than the first, the first one is deselected.
I am struggling on how to check if the first one is clicked on?
$(".checkbox-list").on("change", "input[type=checkbox]", function () {
if ($(this).first()) { // <- not working - how do I know if I clicked the first one?
$("input[type=checkbox]:checked", ".checkbox-list").not(this).prop("checked", false);
$(this).prop("checked", true);
} else {
// Uncheck first checkbox
}
});
Here is a fiddle if you wish to play around: http://jsfiddle.net/4c7aubqL/1/
jsBin demo
$(".checkbox-list").on("change", ":checkbox", function() {
var $all = $(".checkbox-list").find(":checkbox");
var $first = $all.eq(0);
if ($first.is(":checked")) {
$all.not(this).prop("checked", false);
}
});
You should be using radio buttons, not checkboxes. That will do exactly what you want, with no additional effort on your part. Even if you succeed in what you are trying to do, the user interface will look wrong.
I am trying to make the check boxes behave like radio buttons in my ASP .NET MVC Web Application. I have got about 20-30 check boxes grouped in two. For Example:
<input type="checkbox" id="#riggingType.RiggingTypeId 1" name="RiggingTypePlus"
value="#riggingType.RiggingTypeId"
checked="#riggingTypeIds.Contains(riggingType.RiggingTypeId)" />
<input type="checkbox" id="#riggingType.RiggingTypeId 2" name="RiggingTypeMinus"
value="#riggingType.RiggingTypeId"
checked="#riggingTypeIds.Contains(riggingType.RiggingTypeId)" />
Goal:
I want to make the check boxes to behave in such a way that if a Plus Check box is checked then the Minus is unchecked automatically and vice versa. I have written following code to try and achieve this functionality:
$(":checkbox").change(function () {
var inputs = $(this).parents("form").eq(0).find(":checkbox");
var idx = inputs.index(this);
if (this.name.substring(this.name.length - 4, this.name.length) === "Plus") {
// just trying to check if I am getting the right it
// and I am getting the right id
// alert(inputs[idx + 1].id);
// But this does not work
$("#" + inputs[idx + 1].id).prop('checked', false);
}
});
Am I doing something wrong here:
$("#" + inputs[idx + 1].id).prop('checked', false);
Any help will be appreciated.
I know that I can use the radio buttons and group them by same name but I am rendering the elements in a loop so they all have the same name but different values and I don't want to name them differently because I am using this data on the server side... Is there a better way to do this?
Answer:
Got this working using the following:
$(document).ready(function(){
$(":checkbox").on('click', function () {
var $this = $(this);
var inputs = $this.closest("form").find(":checkbox");
if ($this.attr('name').substring(this.name.length - 4, this.name.length) === "Plus" && $this.attr('checked')) {
$this.next().prop('checked', false);
}
else
{
$this.prev().prop('checked', false);
}
});
});

fiddle: https://jsfiddle.net/24gmnjwm/1/
$(document).ready(function(){
$(":checkbox").on('click', function () {
var $this = $(this);
var inputs = $this.closest("form").find(":checkbox");
if ($this.attr('name').substring(this.name.length - 4, this.name.length) === "Plus") {
$this.next().prop('checked', false);
}
});
});
If we can assume that the "plus" checkbox always appears immediately before its related "minus" checkbox then this will do the trick:
$(":checkbox").change(function () {
if ($(this).prop("name").match(/Plus$/)) {
$(this).next().prop("checked", !$(this).prop("checked"));
} else {
$(this).prev().prop("checked", !$(this).prop("checked"));
}
});
sample form:
<form>
<input type="checkbox" name="RiggingTypePlus" value="2" checked />
<input type="checkbox" name="RiggingTypeMinus" value="2" />
<input type="checkbox" name="RiggingTypePlus" value="3" />
<input type="checkbox" name="RiggingTypeMinus" value="3" />
<input type="checkbox" name="RiggingTypePlus" value="4" />
<input type="checkbox" name="RiggingTypeMinus" value="4" />
<input type="checkbox" name="RiggingTypePlus" value="5" />
<input type="checkbox" name="RiggingTypeMinus" value="5" />
</form>

I'm trying to add the values of any checked checkbox to an input text field.
Here's my fiddle: http://jsfiddle.net/Lf6ky/
$(document).ready(function() {
$(":checkbox").on('click', function() {
if ($(':checkbox:checked')) {
var fields = $(":checkbox").val();
jQuery.each(fields, function(i, field) {
$('#field_results').val($('#field_results').val() + field.value + " ");
});
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<input type="text" id="field_results" /><br>
<input type="checkbox" value="1">1<br>
<input type="checkbox" value="2">2<br>
<input type="checkbox" value="3">3
In this example, I have 3 checkboxes, with the values 1,2,3. If I click on all these checkboxes, then the input field should look like this: 1 2 3
If I uncheck any of these checkboxes, then that corresponding value should disappear in the input field.
How do I do this?
I've stored the collection of check-boxes in a variable $checks, then attach the handler to this collection. Inside the event handler, I take the collection once again and filter (return) only the check-boxes that are checked.
map() returns a jQuery object containing the values of the checked check-boxes, get() converts it to a standard array. Join those values with a space and put 'em in the input.
$(document).ready(function(){
$checks = $(":checkbox");
$checks.on('change', function() {
var string = $checks.filter(":checked").map(function(i,v){
return this.value;
}).get().join(" ");
$('#field_results').val(string);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="field_results"/><br>
<input type="checkbox" value="1">1<br>
<input type="checkbox" value="2">2<br>
<input type="checkbox" value="3">3
On click of a checkbox, loop through the checked inputs, append to a string then assign that to your text box:
$(document).ready(function() {
$("input:checkbox").click(function() {
var output = "";
$("input:checked").each(function() {
output += $(this).val() + " ";
});
$("#field_results").val(output.trim());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<input type="text" id="field_results" /><br>
<input type="checkbox" value="1">1<br>
<input type="checkbox" value="2">2<br>
<input type="checkbox" value="3">3
First issue is
if($(':checkbox:checked')) {
will always be true since it returns a jQuery object and an object is a truthy value. If you were to use the if, you want to check the length. aka if($(':checkbox:checked').length) {
Secondly
var fields = $(":checkbox").val();
returns only the first element's value and it returns any checkbox, not just the checked ones. You want to loop through $(':checkbox:checked')
One way to attack it is to use an each and an array.
$(":checkbox").on('change', function() {
var total = [];
$(':checkbox:checked').each( function(){ //find the checked checkboxes and loop through them
total.push(this.value); //add the values to the array
});
$('#field_results').val(total.join(" ")); //join the array
});
Problem
if($(':checkbox:checked')) will always be true
var fields = $(":checkbox").val(); Will give first checkbox value
You can try this.
$(document).ready(function() {
$(":checkbox").on('click', function() {
var fields = '';
$(":checkbox").each(function() {
if (this.checked) {
fields += $(this).val() + ' ';
}
});
$('#field_results').val($.trim(fields))
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<input type="text" id="field_results" />
<br>
<input type="checkbox" value="1">1
<br>
<input type="checkbox" value="2">2
<br>
<input type="checkbox" value="3">3
I have to control the checked status a list of checkboxes from another checkbox.
HTML:
<input id="readall" name="readall" type="checkbox" value="1">
<div id="permGrid">
<input id="recipe.read" name="recipe.read" type="checkbox" value="1" rel="read">
<input id="group.read" name="group.read" type="checkbox" value="1" rel="read">
<input id="ingredients.read" name="ingredients.read" type="checkbox" value="1" rel="read">
</div>
JS:
$('#readall').click(function()
{
var checkStatus = $(this).is(':checked');
var checkboxList = $('#permGrid input[rel="read"]');
$(checkboxList).attr('rel', 'read').each(function(index)
{
if(checkStatus == true)
{
$(this).attr('checked', 'checked');
console.log($(this).attr('checked'));
}
else
{
$(this).removeAttr('checked').reload();
console.log($(this).attr('checked'));
}
});
});
The above code seems fine but the check/uncheck works only for the first time. But when I click the main checkbox second time, it doesn't change the status of other checkboxes into 'checked'. Is there anything I need to do?
I found something similar here. I compared the code and mine and this code is somewhat similar but mine doesn't work.
Try using prop, and shorten the code alot like this
$('#readall').click(function () {
var checkboxList = $('#permGrid input[rel="read"]')
checkboxList.prop('checked', this.checked);
});
DEMO
You can't use a method .reload like this
$(this).removeAttr('checked').reload();
// returns Uncaught TypeError: Object #<Object> has no method 'reload'
Remove it, and it will work.
JSFiddle
Use a class for all the checkboxes which you need to change on click of some checkbox. Like:
<input id="recipe.read" class="toChange" name="recipe.read" type="checkbox" value="1" rel="read" />
I have added a class="toChange" to all the checkboxes except the first one.
<input id="readall" name="readall" type="checkbox" value="1">
<div id="permGrid">
<input id="recipe.read" class="toChange" name="recipe.read" type="checkbox" value="1" rel="read" />
<input id="group.read" class="toChange" name="group.read" type="checkbox" value="1" rel="read" />
<input id="ingredients.read" class="toChange" name="ingredients.read" type="checkbox" value="1" rel="read" />
</div>
Then use the following script:
$('#readall').click(function(){
var checkStatus = $(this).is(':checked');
if(checkStatus){
$(".toChange").attr('checked', 'checked');
}
else{
$(".toChange").removeAttr('checked')
}
});
