Get a list of checked checkboxes in a div using jQuery

Question

I want to get a list of names of checkboxes that are selected in a div with certain id. How would I do that using jQuery?

E.g., for this div I want to get array ["c_n_0"; "c_n_3"] or a string "c_n_0;c_n_3"

<div id="checkboxes">
    <input id="chkbx_0" type="checkbox" name="c_n_0" checked="checked" />Option 1
    <input id="chkbx_1" type="checkbox" name="c_n_1" />Option 2
    <input id="chkbx_2" type="checkbox" name="c_n_2" />Option 3
    <input id="chkbx_3" type="checkbox" name="c_n_3" checked="checked" />Option 4
</div>

Answer 1

Combination of two previous answers:

var selected = [];
$('#checkboxes input:checked').each(function() {
    selected.push($(this).attr('name'));
});

Answer 2

Would this do?

var selected = [];
$('div#checkboxes input[type=checkbox]').each(function() {
   if ($(this).is(":checked")) {
       selected.push($(this).attr('name'));
   }
});

Answer 3

$("#checkboxes").children("input:checked")

will give you an array of the elements themselves. If you just specifically need the names:

$("#checkboxes").children("input:checked").map(function() {
    return this.name;
});

Answer 4

I needed the count of all checkboxes which are checked. Instead of writing a loop i did this

$(".myCheckBoxClass:checked").length;

Compare it with the total number of checkboxes to see if they are equal. Hope it will help someone

Answer 5

This works for me.

var selecteditems = [];

$("#Div").find("input:checked").each(function (i, ob) { 
    selecteditems.push($(ob).val());
});

Answer 6

You could also give them all the same name so they are an array, but give them different values:

<div id="checkboxes">
    <input type="checkbox" name="c_n[]" value="c_n_0" checked="checked" />Option 1
    <input type="checkbox" name="c_n[]" value="c_n_1" />Option 2
    <input type="checkbox" name="c_n[]" value="c_n_2" />Option 3
    <input type="checkbox" name="c_n[]" value="c_n_3" checked="checked" />Option 4
</div>

You can then get only the value of only the ticked ones using map:

$('#checkboxes input:checked[name="c_n[]"]')
            .map(function () { return $(this).val(); }).get()

 agencias.push(item.nextElementSibling.attributes.for.nodeValue);
 });

Answer 8

function listselect() {
                var selected = [];
                $('.SelectPhone').prop('checked', function () {

                    selected.push($(this).val());
                });

                alert(selected.length);

     <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="1" />
         <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="2" />
         <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="3" />
        <button onclick="listselect()">show count</button>

Answer 9

If you need to get quantity of selected checkboxes:

var selected = []; // initialize array
    $('div#checkboxes input[type=checkbox]').each(function() {
       if ($(this).is(":checked")) {
           selected.push($(this));
       }
    });
var selectedQuantity = selected.length;
