在java后台用  
   

 for(int i=0;i<crmWkstExchangeRecordList.size();i++ ){
                    if(i==0){
                        worksheet.setExchangeRecord(crmWkstExchangeRecordList.get(i).getCreateBy().getName()+",  "+DateUtils.formatDateTime(crmWkstExchangeRecordList.get(i).getCreateDate())+",  "+crmWkstExchangeRecordList.get(i).getExchangeRecord()+";     &#13;");
                    }else{
                        worksheet.setExchangeRecord(worksheet.getExchangeRecord()+crmWkstExchangeRecordList.get(i).getCreateBy().getName()+",  "+DateUtils.formatDateTime(crmWkstExchangeRecordList.get(i).getCreateDate())+",  "+crmWkstExchangeRecordList.get(i).getExchangeRecord()+";      &#13;");
                    }
                }

js前台用   \n

  $("#wkstExchangeRecord").val(wkstExchangeRecord+"  \n"+loginUser+",  "+getNowFormatDate()+","+temporaryText);
