Select values of checkbox group with jquery

If you have just one group of checkboxes on your page, to get all the checked checkboxes you can use $('input[type="checkbox"]:checked').  
Select values of checkbox group with jquery 

However, if you have more than one checkbox group, then $('input[type="checkbox"] :checked') is going to select all checked checkboxes from both the checkbox groups.

If you prefer to get checked checkboxes from a specific checkbox group, depending on which button you have clicked, you can use $('input[name="skills"]:checked') or  $('input[name="cities"]:checked'). This will ensure that the checked checkboxes from only the skills or cities checkbox group are selected.

<html>
<head>
    <title></title>
    <script src="jquery-1.11.2.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $('#btnGetSelectedSkills').click(function () {
                getSelectedCheckBoxes('skills');
            });

            $('#btnGetSelectedCities').click(function () {
                getSelectedCheckBoxes('cities');
            });

            var getSelectedCheckBoxes = function (groupName) {
                var result = $('input[name="' + groupName + '"]:checked');
                if (result.length > 0) {
                    var resultString = result.length + " checkboxe(s) checked<br/>";
                    result.each(function () {
                        resultString += $(this).val() + "<br/>";
                    });
                    $('#divResult').html(resultString);
                }
                else {
                    $('#divResult').html("No checkbox checked");
                }
            };
        });
    </script>
</head>
<body style="font-family:Arial">
    Skills :
    <input type="checkbox" name="skills" value="JavaScript" />JavaScript
    <input type="checkbox" name="skills" value="jQuery" />jQuery
    <input type="checkbox" name="skills" value="C#" />C#
    <input type="checkbox" name="skills" value="VB" />VB
    <br /><br />
    Preferred Cities :
    <input type="checkbox" name="cities" value="New York" />New York
    <input type="checkbox" name="cities" value="New Delhi" />New Delhi
    <input type="checkbox" name="cities" value="London" />London
    <br /><br />
    <input id="btnGetSelectedSkills" type="submit" value="Get Selected Skills" />
    <input id="btnGetSelectedCities" type="submit" value="Get Selected Cities" />
    <br /><br />
    <div id="divResult">
    </div>
</body>
</html>

At the moment to get the checked checkboxes values, we are using a button click event. You can also use the click event of the checkbox to do this.

                getSelectedCheckBoxes('skills');
            });

            $('input[name="cities"]').click(function () {
                getSelectedCheckBoxes('cities');
            });

            var getSelectedCheckBoxes = function (groupName) {
                var result = $('input[name="' + groupName + '"]:checked');
                if (result.length > 0) {
                    var resultString = result.length + " checkboxe(s) checked<br/>";
                    result.each(function () {
                        resultString += $(this).val() + "<br/>";
                    });
                    $('#div' + groupName).html(resultString);
                }

Difference between each and map in jquery

Image
$.map $.each map method can be used as an iterator. each method is an immutable iterator Returns a new array Returns the original array The order of callback arguments - element, index. $.map(elems,  function  () { element, index }, arg) The order of callback arguments - index, element. $.each(elems,  function  () { index, element }, arg) Does not have a way to terminate the iteration Return false to terminate the iteration Example :  Notice that the callback arguments in the each method are the reverse of the callback arguments in the map function. Also notice that map returns a new array where as each method returns the original array. This proves the point that each method is an immutable iterator where as map is not. $(document).ready( function  () {      var  intArray = [1, 2, 3, 4, 5];      function  functionA(index, element) {          return ...
