数据导出excel

JS：

            $.ajax({
                type: 'post',
                url: '/Manager/Salary/ExportAllSaleryData?customerId=' + customerId + '&&childIncluded=' + childIncluded + '&&salaryDateStart=' + salaryDateStart + '&&salaryDateEnd=' + salaryDateEnd,
                async: false,
                success: function (data) {
                    var list = eval(data);
                    if (list.length > 0) {

                        var url = '/Manager/Salary/ExportSaleryData?customerId=' + customerId + '&&childIncluded=' + childIncluded + '&&salaryDateStart=' + salaryDateStart + '&&salaryDateEnd=' + salaryDateEnd;
                        var xhr = new XMLHttpRequest();
                        xhr.open('GET', url, true);//get请求，请求地址，是否异步
                        xhr.responseType = "blob";  // 返回类型blob
                        xhr.onload = function () {// 请求完成处理函数
                            if (this.status === 200) {
                                var blob = this.response;// 获取返回值
                                console.log(blob);
                                var a = document.createElement('a');
                                a.download = '员工薪资档案表.xls';
                                a.href = window.URL.createObjectURL(blob);
                                a.click();
                            }
                        };
                        // 发送ajax请求
                        xhr.send();

                        //window.location = '/Manager/Salary/ExportSaleryData?customerId=' + customerId + '&&childIncluded=' + childIncluded + '&&salaryDateStart=' + salaryDateStart + '&&salaryDateEnd=' + salaryDateEnd;
                        }
                    else {
                        var msgs = "该客户暂无" + salaryDateStart + "-" + salaryDateEnd + "月度数据！";
                        layer.msg(msgs, { icon: 5, time: 3000 });
                    }
                }
            })

　　

应该也可以不使用xhr,用window.locaion就完事了，一般用xhr处理图片之类的。直接<a>标签更省事？

后端c#代码：

        public ActionResult SalaryExport()
        {
            return View();
        }

            string salaryDateEnd = string.IsNullOrEmpty(Request["salaryDateEnd"]) ? null : Request["salaryDateEnd"];//得到js传来的导出选项

            string templatePath = AppSetting.EmploySalaryInfoExportTemplate;  //文件模板路径
            var salaryDataList = _salaryService.GetExportData(customerId, childIncluded, salaryDateStart, salaryDateEnd);//获取数据

emmmm，比较坑的是我忘记在服务器上添加作为文件模板的.xls了，导致本地运行正常，访问服务器上则一直报500，找不到资源。
