 $('#field1,#field2').on('input propertychange paste', function() {


     $('#totalPrice').html(parseFloat($("#field1").val()!=''?$("#field1").val():0)+parseFloat($("#field2").val()!=''?$("#field2").val():0));
    });

    $(document).ready(function () {
        jQuery('#field2, #field1').on('input propertychange paste', function () {
            var op1 = document.getElementById('field1');
            var op2 = document.getElementById('field2');
            var result = document.getElementById('totalPrice');
            if (op1.value == "" || op1.value != parseFloat(op1.value)) op1.value = 0;
            if (op2.value == "" || op2.value != parseFloat(op2.value)) op2.value = 0;
            result.value = 0;
            result.value = parseInt(result.value);
            result.value = parseInt(result.value) + parseInt(op1.value) + parseInt(op2.value);
            var divobj = document.getElementById('totalPrice'); divobj.style.display = 'block'; divobj.innerHTML = "Total $" + result.value;
        })            
    });
