ABP框架按条件导出

web层

.js导出事件：

//导出为excel文档
$('#btn-export').click(function () {
//得到查询的参数
var temp = { //这里的键的名字和控制器的变量名必须一直，这边改动，控制器也需要改成一样的
ProcessSteps_RecordId: $("#ProcessSteps_RecordId").val(),
OperationModeId: $("#OperationModeId").val(),
ScanCodeProduce: $("#ScanCodeProduce").val(),
ReceiveValue: $("#ReceiveValue").val(),
IsOK: $("#IsOK").val(),
SerialNumber: $("#SerialNumber").val(),
OperationCategory: $("#OperationCategory").val(),
StationId: $("#StationName").val(),
LineId: $("#LineName").val(),
MinTime: $("#MinTime1").val(),
MaxTime: $("#MaxTime1").val()
};

layer.load(0, {
shade: [0.3, '#000'] //0.1透明度的白色背景
});

_processSteps_Detail_RecordService
.getProcessSteps_Detail_RecordToExcel(temp)
.done(function (result) {
layer.closeAll('loading');
app.downloadTempFile(result);
});

});

注释：

‘#’后面的字符是HTML里的Id名

temp 里面是条件（这个将传给Application层的方法），getProcessSteps_Detail_RecordToExcel(temp)方法是对应的Application层的方法。

Application层

接口：

Task<FileDto> GetProcessSteps_Detail_RecordToExcel(GetProcessSteps_Detail_RecordInput input);

方法：

public async Task<FileDto> GetProcessSteps_Detail_RecordToExcel(GetProcessSteps_Detail_RecordInput input)
{
var OperationCategoryDir = DictionaryDto.OperationCategoryDir;
var IsOKDir = DictionaryDto.IsOKDir;

//初步过滤
var query = from pdr in _processSteps_Detail_RecordRepository.GetAll()
join ed in _EnumDictRepository.GetAll() on pdr.OperationModeId equals ed.Id
join pr in _processSteps_RecordRepository.GetAll() on pdr.ProcessSteps_RecordId equals pr.Id
join p in _ProcessStepsRepository.GetAll() on pr.ProcessStepsId equals p.Id
join s in _StationRepository.GetAll() on p.StationId equals s.Id
join l in _LineRepository.GetAll() on s.LineId equals l.Id
orderby pdr.Id descending
select new ProcessSteps_Detail_RecordListDto()
{
Id = pdr.Id,
LineId = l.Id,
};

query = query
.WhereIf(!(input.LineId == "0"), u => u.LineId == LineId)
;

var list = query.ToList();

var fileDto = _processSteps_Detail_RecordListExcelExporter.ExportProcessSteps_Detail_RecordToFile(list);

return fileDto;
}
