        void txtVehicleNum_TextChanged(object sender, EventArgs e)        {             DangerClassDataBind();        }

        { 
            txtVehicleNum.Attributes["OnBlur"] = ClientScript.GetPostBackEventReference(btnTemp, null);  
        }

        void btnTemp_Click(object sender, EventArgs e)        {            DangerClassDataBind();        }

方法三：推荐

                if (returnValue != null) {
                    var strvalue = returnValue.split('|'); 
                    document.getElementById("<%=txtVehicleNum.ClientID %>").value = strvalue[0];
                    document.getElementById("<%=txtPlateColor.ClientID %>").value = strvalue[1];
                    document.getElementById("<%=txtPlateColorName.ClientID %>").value = strvalue[2];

                    document.getElementById("btnTemp").click();
                }
            }
