I have got this checkbox which has value 1.

<input type=checkbox name=option_1 id=checkbox_1 value=1>

Also I use this method to make checked/unchecked it.

$('input[id^=checkbox_]').not('#checkbox_all').click(function () {

            $('#checkbox_all').prop('checked', false);



    // Get 'VALUE' of the checkbox here   



});

What I need is somehow get 'VALUE' of the clicked checkbox. So In that case it should be 1.

Any clue how do it could be done?

Thank you!
