Check if checkbox is checked with jQuery

Question

Check if checkbox is checked with jQuery

How might I check if a checkbox in a checkbox array is checked utilizing the id of the checkbox array?

I'm utilizing the accompanying code, however, it generally returns the count of checked checkboxes regardless of id.

function isCheckedById(id) {

    alert(id);

    var checked = $("input[@id=" + id + "]:checked").length;

    alert(checked);



    if (checked == 0) {

        return false;

    } else {

        return true;

    }

}

$('#checkbox').is(':checked');

The above code returns true if the checkbox is checked or false if not.

All following methods are useful:

$('#checkbox').is(":checked")



$('#checkbox').prop('checked')



$('#checkbox')[0].checked



$('#checkbox').get(0).checked

It is recommended that DOMelement or inline "this.checked" should be avoided instead jQuery on method should be used event listener.
