Is checkbox checked (inside each() loop)?

Question

Hello,

I'm looping through multiple checkboxes with the same class with function each() and inside the loop I need to be able to tell whether the checkbox is checked or not. How to do that?

$('.checkbox').each(function() {
    var is_checked = 'no';
    // I need to change the value of the is_checked variable to 'yes'
    // if the checkbox is checked
    //
});

Answer 1

Use

var is_checked = this.checked ? 'yes' : 'no';

Answer 2

One way is:

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

Answer 3

Why not use the :checkbox:checked selector instead? That way you get the list of all the checkboxes that are checked and iterate over those.

Answer 4

This will get all the unchecked boxes

$("input:not(:checked)")

Answer 5

I believe $(this).val() will give you "true" if checked and then $(this).val("true") will set the value

Answer 6

$("input:checkbox[class='.checkbox']:checked").each(function () {
 // this will only loop thru checked boxes (checked = true)
}

OR

$('.checkbox').each(function() {    
 // or return a boolean for each one
 var is_checked = $(this).is(":checked");
});
