.net老项目中Jquery访问webservice

1. xml类型返回

javascript 复制代码

    jQuery.ajax({
        type: "POST",
        async: false,
        url: "WebService/Evection.asmx/GetCheckUpApplyEForm",
        contentType: "application/json",
        data: "{lngEvectionID:" + eformSNOriginal + "}",
        dataType: 'xml', //返回的类型为XML ，和前面的Json，不一样了
        success: function(result) {
            //演示一下捕获
            try {
                $(result).find("NewDataSet").each(function() {
                if (!bool) {
                        jQuery("#dtmOperatorDate_corres").val($(this).find("WebFlowGlideNo").text());
                        jQuery("#strCheckUpSubsidy").val($(this).find("strCheckUpSubsidy").text());
                        bool = true;
                    }
                });
            }
            catch (e) {
                alert(e);
                return;
            }
        },
        error: function(result, status) { //如果没有上面的捕获出错会执行这里的回调函数
            if (status == 'error') {
                return showError("健康申请列表载入出错。");
            }
        }
    });

对应c#代码

csharp 复制代码

    [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Xml)]
        public DataSet GetCheckUpApplyEForm(int lngEvectionID)
        {
            clsEvectionApply obj = new clsEvectionApply();
            DataSet ds = new DataSet();
            ds = obj.GetCheckUpApplyEForm(lngEvectionID);
            return ds;
        }

json返回

javascript 复制代码

function loadEvectionDetailList(beginDate, endDate) {
            var arrBgColor = ["#f2effe", "#fafafa"];
            var table = $("#tabEvection");
            var arrObj = null;

            table.find("tr:not(:first)").remove();
            $.ajax({
                type: "POST",
                contentType: "application/json",
                async: false,
                url: "../../WebService/Evection.asmx/GetFlowDataDetailJson",
                dataType: 'json',
                data: "{employeeID:'" + $N("bnEmployeeID_TextValue").value + "',beginDate:'" + beginDate + "',endDate:'" + endDate + "',showType:4}",
                success: function (result) {
                    arrObj = $.parseJSON(result.d).NewDataSet;
                }
            });


            if (arrObj != null) {
                for (var i = 0; i < arrObj.length; i++) {
                    var tr = $("<tr>");
                    tr.css("background-color", arrBgColor[i % 2]);
                    tr.append($("<td><input type=radio name=radEForm value=" + arrObj[i]["lngCheckUpID"] + "," + arrObj[i]["WebFlowGlideNo"] + "," + arrObj[i]["strCheckUpSubsidy"] + "></td>"));
                    tr.append($("<td>" + arrObj[i]["WebFlowGlideNo"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strEmployeeName"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["dtmOperatorDate"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strRealApplyerName"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strTWJobName"] + "</td>"));

                    tr.append($("<td>" + arrObj[i]["strCheckpoint"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strCheckDate1"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strCheckDate2"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strAuditName"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["dtmAuditDate"] + "</td>"));
                    tr.append($("<td>" + arrObj[i]["strRemark"] + "</td>"));
                    table.append(tr);
                }
            }
        }

对应c#代码

csharp 复制代码

using Newtonsoft.Json;
    [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
