需求：將用戶的違約金信息導出為excel表格格式
步驟
1. 數據庫中增加按鈕的值（註意上級編號要和頁面隱藏域中的相等）
DZ內容（頁面加載時根據SJBH查詢數據庫內容，讀取DZ字段信息並加載樣式及方法）
<a href="javascript:void(0)" class="easyui-linkbutton" data-options="iconCls:‘icon-remove‘" onclick="getWyj();">違約金查詢</a>
頁面加載後菜單欄出現“違約金查詢”按鈕
2. 創建js方法
sf_wyjcx.js
function getWyj(){ var userNode = frames[‘threeModel‘].$("#topUserList").datagrid("getSelected"); if (!userNode) { pubAlertMessage({ "msg" : "請選擇用戶信息!", "type" : BDXC_ALERT_TYPE.INFO }); return; } var yhbh = userNode.YHBH;var postData = { ‘jmjs.yhbh‘ : yhbh }; var paramJson = { "winDivId" :"getWyjWin", "title" :"違約金查詢", "width" :920,//300, // 790 "height" :400, // 520 "iconCls" :"icon-edit", "inDivId" :"getWyj","loadUrl" :"UserPayAction!getWyj.action", "postData" :postData, "watingTime":100, "defineFun":"exportExcel("+yhbh+")", "initFunc":"" }; //pubLoadWinPage(paramJson); pubLoadWyj(paramJson); } function pubLoadWyj(paramJson) { var watingStartJson = { "time" : paramJson.watingTime }; pubWatingStart(watingStartJson); $.ajax({ url : paramJson.loadUrl, type : ‘post‘, data : paramJson.postData, dataType : ‘html‘, error : function (e) { pubWatingEnd(); pubAlertMessage({ "msg" : "加載頁面失敗!", "type" : BDXC_ALERT_TYPE.ERROR }); }, success : function (data) { pubWatingEnd(); var winDiv = $(‘#‘ + paramJson.winDivId); if (winDiv.length == 0) { $(‘<div id="‘ + paramJson.winDivId + ‘"></div>‘).appendTo(document.body); } var canelFun = "pubWinClose(‘" + paramJson.winDivId + "‘,‘‘);"; if (paramJson.canelFun) { canelFun = "pubWinClose(‘" + paramJson.winDivId + "‘,‘" + paramJson.canelFun + "‘);"; } var inDivId = paramJson.inDivId || paramJson.winDivId + ‘Content‘; paramJson.inDivId = inDivId; paramJson.winHtml = ‘<div class="easyui-layout" fit="true">‘ + ‘<div id="‘ + paramJson.inDivId + ‘" region="center" border="false" class="winDataContent">‘ + data + ‘</div>‘; if (!paramJson.isNormal) { paramJson.winHtml += ‘<div region="south" border="false" class="winOpLine" style="float:right">‘ + ‘<a id="btnCancel" class="easyui-linkbutton" icon="icon-cancel" href="javascript:‘ + canelFun + ‘">關閉</a>‘ + ‘<a id="btnEp" class="easyui-linkbutton" icon="icon-ok" href="javascript:‘ + paramJson.defineFun + ‘" >導出</a>‘ + ‘</div>‘; } paramJson.winHtml += ‘</div>‘; pubInitWindow(paramJson); } }); } //導出表格 function exportExcel(yhbh){ var url = "UserPayAction!getWyjExcel.action?yhbh="+yhbh; $.messager.confirm("操作提示","是否導出違約金信息？",function(data){ if(data){ location.href = url; } }); }
3. 點擊菜單欄的“違約金查詢”首先加載用戶所有的違約金信息
後臺方法如下：
UserPayAction.java
// 查詢違約金 public String getWyj(){ jmjs.setYhbh(jmjs.getYhbh()); List list=userPayService.getWyjlist(jmjs); jmjs.setList(list); return "addwyj"; }
UserPayDaoImpl.java
public List getWyjlist(SfJmjsT vo){ List list = new ArrayList(); StringBuilder sql = new StringBuilder(); List result = null; sql.append("select a.*,b.*,c.* from (select cnq,sfmj,dj,ysje,sfje,qfje,decode(sfhjwyj,‘否‘,SF_ZNJ_F_CFD(‘居民‘,yhbh,?,cnq),znjys)znj," + "SF_ZNJ_F_TS(yhbh,?,cnq)ts from sf_jmjs_t where zf=0 and qfje>0 and yhbh=? )a," + "(select sum(qfje) zqf,sum(decode(sfhjwyj,‘否‘,SF_ZNJ_F_CFD(‘居民‘,yhbh,?,cnq),znjys))zznj from sf_jmjs_t " + "where zf=0 and qfje>0 and yhbh=?)b,(select yhbm,yhkh,yhmc,lxdh,fgs,qy,rlz,xq,dz from sf_jmyh_t where zf=0 and yhbh=?)c"); Date da=new Date(); SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); String dateString = formatter.format(da); DateFormat format1 = new SimpleDateFormat("yyyy-MM-dd"); Date date=null; try { date = format1.parse(dateString); } catch (ParseException e) { e.printStackTrace(); } list.add(date); list.add(date); list.add(vo.getYhbh()); list.add(date); list.add(vo.getYhbh()); list.add(vo.getYhbh()); try { result = this.executeSqlList(sql.toString(), list.toArray(), SfJmjsT.class); } catch (BDXCException e) { e.printStackTrace(); logger.error(BDXCUtil.getExceptionString(e)); } return result; }
返回的數據在頁面進行遍歷
sf_wyjcx.jsp
