js 取值，赋值

            var idval = $('#id').datetimebox('getValue');  //datagrid时间框取值
            var idval = $('#id option:selected').val();    //下拉列表框取值

            document.getElementById("orderLevel").options[0].selected = true;  //下拉列表设置默认值

            var idval = document.getElementById("id").value;     //文本框取值

            var val =document.getElementsByName("name");
            for (var i = 0, j = val.length; i < j; i++){
                var nameval = val[i].value;                  //根据name取值
            }
