Select values of checkbox group with jquery

Select values of checkbox group with jquery

In this video we will discuss, how to select values of checked checkboxes that are in different groups using jQuery. Along the way, we will also discuss how to pass a variable to jquery selector.


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



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 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');
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.

head
title /title
script type="text/javascript"
$(document).ready(function () {
$('input[name="skills"]').click(function () {
getSelectedCheckBoxes('skills');
});
$('input[name="cities"]').click(function () {
getSelectedCheckBoxes('cities');
});
var getSelectedCheckBoxes = function (groupName) {
var result = $('input[name="' + groupName + '"]:checked');
resultString += $(this).val() + " br/ ";
});
$('#div' + groupName).html(resultString);
}
else {
$('#div' + groupName).html("No checkbox checked");
}
};
});
/script
