重构授课班时间安排模块代码
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1.很多的模塊除了首頁index.jsp主要還有兩個界面，一個添加，另一個是編輯頁面，授課班時間安排也是如此。之前的做法是做了兩個頁面，操作方面，兩者基本上都是獨立的，因為感覺兩個頁面不好整合在一起，但是這樣肯定是不好的，兩者都是commit操作，應該是可以整合起來的，所以，我今天就來改改吧，記錄下來，以備以后查看
界面：
add.jsp

this.itList[i];var item_id = "item_" + oneItem.itemId;var btList = eval(this.name + ".classMap." + item_id);var oneClass = btList[j];var fromObj = {};fromObj.type="add";fromObj.className = oneClass.className;fromObj.itemName = oneItem.itemName;fromObj.itemId = oneItem.itemId;fromObj.classId = oneClass.classId;var p = getParent();p.openParentDlg("ADDCLASSTIME", "授課班時間安排", 380, 360, fromObj,"CLASSTIME", "AddClassTimeIni", "&type="+fromObj.type+"&itemId=" + oneItem.itemId+ "&classId=" + oneClass.classId, window, true, true,"ClassTimeRet", "");}; edit： this._onClick = function(oneLc) {event.cancelBubble = true;if (oneLc != null) {var fromObj = {};fromObj.type="edit";fromObj.eDate=oneLc.eDate;fromObj.className = oneLc.oneClass.className;fromObj.itemName = oneLc.oneItem.itemName;fromObj.schId = oneLc.id;var p = getParent();p.openParentDlg("EDITCLASSTIME", "編輯授課班時間安排", 380, 360, fromObj,"CLASSTIME", "EditClassTimeIni", "&type="+fromObj.type+"&schId=" + fromObj.schId,window, true, true, "ClassTimeRet", "");}}; 這個方法給下一個頁面 add.jsp/edit.jsp 傳遞了一個對象fromObj，里面存放了一個很重要的屬性type，它是用來區別編輯操作的！還要注意的就是回調函數 ClassTimeRet 寫在 index.jsp 中這個回調函數是當新打開的窗體關閉了時觸發的，這里就是當返回的值是“T”時，就重新刷新頁面 function ClassTimeRet(p_RetData, p_InData) {if (p_RetData.data == "T") {doRefresh("CLASSTIME", "getLabClassDate", true, "", "", "");}}同時還有一個回調函數，當點擊了新的頁面（添加或者編輯）就會觸發的方法
添加的：
function AddClassTime() {var fobj={};fobj.type="add";if (confirm("是否提交數據？")) {doRefresh("CLASSTIME", "addClassTime", true, "","&type="+fobj.type,"ClassTimeCommitRet","");}}編輯的：
function EditClassTimeCommit() {var fobj = {};fobj.type = "edit";//如果過期則不可編輯var eDate=null;eDate = tObj.eDate;lastDate = new Date(eDate.replace(/-/g, "/"));if (Date.parse(lastDate) < Date.parse(this.today)) {alert("該時間段已過期，無法進行編輯");thisDlg.closeDlg();} else if (confirm("是否保存數據？")) {doRefresh("CLASSTIME", "updateClassTime", true, "", "&type="+ fobj.type, "ClassTimeCommitRet");}}他們調用同一個回調函數
function ClassTimeCommitRet(retObj, data) {if (data == "T") {var rObj = {};rObj.data = data;thisDlg.returnObj = rObj;thisDlg.closeDlg();} else {alert(data);}} 當返回的值是“T” 時，就構造一個新的對象rObj并作為這個窗體的返回值返回給上一個窗體（也就是index.jsp），之后就關閉當前的窗體?
重構的步驟：第一步：整合add.jsp和edit.jsp，新建一個jsp：commit.jsp，界面基本上借用add.jsp，但是要整合edit.jsp中其他的內容，包括js方法以及不同的隱藏域，同時修改提交按鈕觸發的js方法commit.jsp<%@page contentType="text/html; charset=gbk"%> <%@ taglib

可以看到的就是在三個不同的地方都是使用了判斷type是add還是edit，不能和在一起是因為操作是有一定的順序的?第三步：修改 labclass.js this._onClick = function(oneLc) {event.cancelBubble = true;if (oneLc != null) {var fromObj = {};fromObj.type="edit";fromObj.eDate=oneLc.eDate;fromObj.className = oneLc.oneClass.className;fromObj.itemName = oneLc.oneItem.itemName;fromObj.schId = oneLc.id;var p = getParent();p.openParentDlg("EDITCLASSTIME", "編輯授課班時間安排", 380, 360, fromObj,"CLASSTIME", "CommitClassTimeIni", "&type="+fromObj.type+"&schId=" + fromObj.schId,window, true, true, "ClassTimeRet", "");}};修改調用的后臺方法就可以了
?
第四步：整合處理方法addClassTime和editClassTime，根據的也是前臺傳過來的type屬性值
/** * <p> * 方法名稱: do_commitClassTime * </p> * <p> * 方法功能描述: 更新授課班時間安排 * </p> * <p> * 輸入參數描述: BSObject m_bs:BinaryStar框架參數集。 * </p> * <p> * 輸出參數描述: BSObject：BinaryStar框架參數集。 * </p> */public BSObject do_commitClassTime(BSObject m_bs) throws Exception {int count = 0;String retStr = "操作失敗，請稍后再試";//得到操作的類別，授課班時間安排id和實驗室idString type = (String)m_bs.getPrivateMap().get("type");String schId = (String) m_bs.getPrivateMap().get("schId");String labId = ((VBSSelect) m_bs.getTagMap().get("LabClass_LabList")).getCurSelectValue();// 通過前臺得到并設置一個授課班時間安排ClassTimePojo oneClassTime = new ClassTimePojo();if(type.equals("edit")){oneClassTime.setId(schId);}else if(type.equals("add")){oneClassTime.getOneItem().setItemId((String) m_bs.getPrivateMap().get("add_itemid"));oneClassTime.getOneClass().setClassId((String) m_bs.getPrivateMap().get("add_classid"));}oneClassTime.setsDate((String) m_bs.getPrivateMap().get("classSDate"));oneClassTime.seteDate((String) m_bs.getPrivateMap().get("classEDate"));oneClassTime.setsTime("csu_" + (String) m_bs.getPrivateMap().get("classSTime"));oneClassTime.seteTime("csu_" + (String) m_bs.getPrivateMap().get("classETime"));SqlExecute sqlHelper = new SqlExecute();ArrayList<ClassTimePojo> list = null;try {sqlHelper.setAutoCommit(false);BSClassTimeDBMang ctDB = new BSClassTimeDBMang(sqlHelper, m_bs);list = ctDB.getLabClassTimeList(labId);// 得到實驗室的所有授課班時間安排 if (type.equals("add")) {retStr = _validateClassTime(oneClassTime, list, "");if (retStr.equals("OK")) {// 只有可以插入時才進行插入操作count = ctDB.intsertClassTime(oneClassTime);if (count > 0) {retStr = "T";} else {retStr = "沒有更新任何數據!";}}} else {retStr = _validateClassTime(oneClassTime, list, schId);if (retStr.equals("OK")) {// 只有可以更新時才進行更新操作count = ctDB.updateClassTime(oneClassTime);if (count > 0) {retStr = "T";ClassTimePojo beforePojo = ctDB.getScheduleInfo(schId);// 得到修改前的信息this._delLabClassByClassTime(beforePojo, oneClassTime, labId, ctDB);} else {retStr = "沒有更新任何數據!";}}}sqlHelper.commit();} catch (Exception e) {sqlHelper.rollback();e.printStackTrace();throw e;}m_bs.setRetrunObj(retStr);return m_bs;} 至此，我重新測試了一遍，功能和以前一樣，但是代碼明顯少了很多啊，呵呵呵，重構！總結
以上是生活随笔為你收集整理的重构授课班时间安排模块代码的全部內容，希望文章能夠幫你解決所遇到的問題。
