推荐答案



var ddlproduct1 = document.getElementById('<%=ddlproducttype1.ClientID%>');
            var ddlproductype1 = ddlproduct1.options[ddlproduct1.selectedIndex].value;
            if (ddlproductype1 == 0) {
                document.getElementById('<%=ddlproducttype1.ClientID %>').className = 'styletxtmandatory';
//                alert("Select Product Type.");
                return false;
            }
