You can do it like that.

function GetTextValue() {

    $(divValue).empty(); 
    $(divValue).remove(); values = '';

    $('.input').each(function() {
        divValue = $(document.createElement('div')).css({
            padding:'5px', width:'200px'
        });
        if (this.value == '') {
           // alert('Empty');
        } else if (values != '') {
            values += ',';
        }
        values += this.value;
    });
    document.all.contact_list.value = values;
}

JSFiddle

Hope it will be useful for you.

Alert if `this.value` is empty ?? – Arkar Aung Apr 09 '15 at 08:19
Shouldn't that be `if (this.value != '')` - he only wants to add commas if there is another value, so checking if values is not empty will add extra commas on the end – Pete Apr 09 '15 at 08:21
is this right? if (values != '') { alert('text'); values += ','; } thanks – rish Apr 09 '15 at 08:21
sorry, how to test, if i enter more email id with using alert? thanks – rish Apr 09 '15 at 08:48
@rish I added JSFiddle link to test it. Thanks – Arkar Aung Apr 09 '15 at 08:59

function GetTextValue() {
    $(divValue).empty();
    $(divValue).remove(); 
    var values = '';

    $('.input').each(function() {
        divValue = $(document.createElement('div')).css({
            padding:'5px', width:'200px'
        });
        if(this.value.trim() != ''){
            if(values != ''){
                values += ',';
            }
            values += this.value.trim();
        }
    });
    document.all.contact_list.value = values;
}

       if(this.value != '') {
           values += this.value;
           values += ',';
       }
    });
    document.all.contact_list.value = value.substring(0, value.length - 1);//remove last comma
}
