java 功能点
1. 根据页面中table返回excel,不请求后台
.factory('exportExcelService',function($window){ var uri='data:application/vnd.ms-excel;base64,', template='<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>', base64=function(s){return $window.btoa(unescape(encodeURIComponent(s)));}, format=function(s,c){return s.replace(/{(\w+)}/g,function(m,p){ return c[p]; })}; return { tableToExcel:function(tableId,worksheetName){ var table=$(tableId); var ctx={worksheet:worksheetName,table:table.html()}; var href=uri+base64(format(template,ctx)); return href; } }; })
2. 后台请求生成excel
@RequestMapping("/exportExcelRecord")
public void ExportExcelRecord(MedicalCardModel medicalCardModel,HttpServletResponse response){
List<MedicalCardResultModel> result=medicalCardService.getMedicalRecord(medicalCardModel);
int size = result.size();
OutputStream out =null;

Map<String, String> mapGender = new HashMap<String, String>();
mapGender.put(IS_MAN+"", GenderEnums.getName(IS_MAN));
mapGender.put(IS_WOMAN+"", GenderEnums.getName(IS_WOMAN));
edf.set("gender", mapGender);
List<MedicalCardResultModel> list =null;
for (int i = 0; i < size; i = i + EXCEL_MAX_FROM＿DB) {
list=(size-i>EXCEL_MAX_FROM＿DB?result.subList(i, i + EXCEL_MAX_FROM＿DB):result.subList(i,i+size));
ExcelBasePoiUtils.getWorkBook(list, sh, wb, edf);
}
wb.write(out);
wb.dispose();
ExcelBasePoiUtils.close(out);
} catch (Exception e) {
}
}

/** * 释放资源 * @param os * @throws IOException */ public static void close(OutputStream os) throws IOException{ ThreadLocalUtils.remove(); os.flush(); os.close(); }

4. 点击编辑，编辑变保存，输入框可编辑，获取焦点
<td style="padding: 0px 0px;"> <input type="text" name="correction" class="form-control" ng-model="cor.correction" ng-readonly="checkEdit"/> </td> <td>{{cor.operator}}</td> <td>{{cor.updatetime | date:'yyyy-MM-dd'}}</td> <td> <a href="javascript:void(0)" class="operate_a" ng-click="editSec($event,cor.id,cor.correction)">编辑</a>
$scope.checkEdit = true;
$scope.editSec = function (event,id,context) { if(angular.element(event.target).context.innerHTML == "编辑"){ $scope.checkEdit = false; angular.element(event.target).parents("tr").find("input").focus(); angular.element(event.target).context.innerHTML = "保存"; }else{ $scope.updateCor(id,context); $scope.checkEdit = true; angular.element(event.target).context.innerHTML = "编辑"; } }
