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.
Replace < with LESSTHAN symbol and > with GREATERTHAN symbol.
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.

$(‘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);
}
else {
$(‘#div’ + groupName).html(“No checkbox checked”);
}
};
});
