Jquery Append And Remove Values From Checkbox To Textarea

I am trying to append or remove values of checkbox to textarea, I tried using the following code which is working fine with textbox but not textarea. Also, it just adds information

Solution 1:

You could do something more like this

var checkboxes = $("#alloptions li input[type='checkbox']");

checkboxes.on('change', function() {
    $('#fulloptions').val(
        checkboxes.filter(':checked').map(function(item) {
            returnthis.value;
        }).get().join(', ')
     );
});

FIDDLE
