MVC+easyui-datagrid之查看详情

          在做GXPT时，我负责课表这块儿，而这块儿最大的特点是很难用到大家公共的东西，只能自己一点点去做，其中之一就是查看详情，这个功能我做了大概有两天时间，下面是我做的成果：

          

         点击查看详情后，要弹出对应ID 的内容，如下：

           

          下面看一下这个功能的具体实现：

            先看View:           

<span style="font-size:14px;"><table id="dgTimeTable" class="easyui-datagrid" style="position: relative;height:auto;" data-options="url:'/BasicTimeTable/QueryTimeTable/',checkbox:true,resizable:true,collapsible:true,method:'get',autoColWidth:true,pageSize:10,rownumbers:true,pagination:'true',fitColumns:true">                <thead>                    <tr>                        <th data-options="field:'ck',checkbox:true"></th>                        <th data-options="field:'TimeTableID',hidden:true">课表ID</th>                        <th data-options="field:'OnClassName',hidden:true">上课班名称</th>                        <th data-options="field:'CourseName'">课程名称</th>                        <th data-options="field:'Cycle'">周期</th>                        @*<th data-options="field:'weekly',width:100">周次</th>*@                        <th data-options="field:'StratWeek'">开始周</th>                        <th data-options="field:'EndWeek'">结束周</th>                        <th data-options="field:'StartSectionName'">开始节次</th>                        <th data-options="field:'EndSectionName'">结束节次</th>                        <th data-options="field:'Week'">星期</th>                        <th data-options="field:'BuildingName'">建筑</th>                        <th data-options="field:'RoomName'">教室</th>                        <th data-options="field:'OnClassNamey',<strong><span style="color:#ff0000;">formatter: rowformater</span></strong>">上课班信息</th>                        <th data-options="field:'operation',formatter:formatOper,hidden:true">操作</th>                        <th data-options="field:'TeacherName',hidden:true">授课教师</th>                        <th data-options="field:'courseID',hidden:true">课程ID</th>                        <th data-options="field:'CourseType',hidden:true">课程类型</th>                        <th data-options="field:'CourseProperty',hidden:true">课程性质</th>                        <th data-options="field:'Semeter',hidden:true">学年学期</th>                        <th data-options="field:'Period',hidden:true">学时</th>                        <th data-options="field:'Credit',hidden:true">学分</th>                        <th data-options="field:'Totalmember',hidden:true">                        人数</th>                         <th data-options="field:'StudentNo',hidden:true">                        学号</th>                        <th data-options="field:'Name',hidden:true">姓名</th>                           <th data-options="field:'ClassName',hidden:true">班级</th>                          <th data-options="field:'GradeName',hidden:true">年级</th>               <th data-options="field:'Profession',hidden:true">专业</th>               <th data-options="field:'pProfession',hidden:true">学院</th>                                            </tr>                </thead>            </table>        </div>    </div></div></span>

               加红处就是我要处理的“查看详情”的地方，下面再JS中给这个字段附上事件：

              

<span style="font-size:14px;"><script type="text/javascript">    //查看详情界面    function <strong>showDialog</strong>(aa, courseName, courseType, teacherName, semeter, period, credit, totalmember, organization, timetableid) {        //document.getElementById("courseID").innerText = courseid;        document.getElementById("CourseProperty").innerText = aa;        document.getElementById("CourseName").innerText = courseName;        document.getElementById("CourseType").innerText = courseType;        document.getElementById("TeacherName").innerText = teacherName;        document.getElementById("semeter").innerText = semeter;        document.getElementById("Period").innerText = period;        document.getElementById("Credit").innerText = credit;        document.getElementById("Totalmember").innerText = '45';        document.getElementById("Organization").innerText = organization;        document.getElementById("TimeTableID").value = timetableid;        $('#dlgOnClassDetail').dialog('open').dialog('setTitle', '上课班信息');    }    //查看详情超链接    function rowformater(value, row, index) {        return "<a  href='#' onclick='<strong><span style="color:#ff0000;">showDialog</span></strong>(" + '" ' + row.CoursepropertyName + '"' + "," + '" ' + row.CourseName + '"' + "," + '" ' + row.CourseTypeName + '"' + "," + '"' + row.teacherName + '"' + "," + '" ' + row.Semeter + '"' + "," + '" ' + row.Period + '"' + "," + '" ' + row.Credit + '"' + "," + '" ' + row.TotalMember + '"' + "," + '" ' + row.OrganizationName + '"' + "," + '"' + row.TimeTableID + '"' + ")'>查看详情</a>";    } </script></span>

            下面是controller中的内容：

<span style="font-size:14px;"> public ActionResult QueryTimeTable(string strLike)        {            int pageSize = Request["rows"] == null ? 10 : int.Parse(Request["rows"]);            int pageIndex = Request["page"] == null ? 1 : int.Parse(Request["page"]);            int total;            List<TimeTable> timetableList = new List<TimeTable>();            //strLike = Request.Form["strLike"];            if (strLike == "" || strLike == null)            {                timetableList = iBasicTimeTable.QueryTimeTable(pageSize, pageIndex, out total);            }            else            {                timetableList = iBasicTimeTable.FuzzyQueryTimeTable(strLike);//查询到匹配的list            }            //将list转换成json字串，需要序列化            JavaScriptSerializer servializer = new JavaScriptSerializer();//实例化一个序列化对象            string strTimeTableJson = servializer.Serialize(timetableList);            var data = new            {                //total,                rows = timetableList            };            return Json(data, JsonRequestBehavior.AllowGet);        }</span>

              在我的需求中用到了对多个表的操作，包括节次、上课班、课程、教师、学生、建筑，所以说在底层，也就是WCF中的实现，难度也大大加大，因为返回的界面的内容很多，包括很多的表，所以，下面来看看我底层的实现：底层用的是三层+WCF+ViewModel+EF             

<span style="font-size:14px;"> public List<TimeTable> QueryTimeTable(int pageSize, int pageIndex, out int total)        {   //实例化一个数据泛型集合            List<TimeTable> timetablelist = new List<TimeTable>();            //调用BLL层接口            var result = IBasicTimeTable.LoadPageItems(pageSize, pageIndex, out total, p => p.TimeTableID, true);            //使用循环，遍历IQuerble集合，赋值到数据契约            foreach (var item in result)            {                List<Student> studentlist = new List<Student>();                //构造器                //var onclassstudentlist = IBasicOnClass.LoadEnities(n => n.OnClassID == item.OnClassID).ToList();                var onclassstudentlist = IBasicOnClassStudent.LoadEnities(n => n.OnClassID == item.OnClassID).ToList();                foreach (var studentTmp in onclassstudentlist)                {                    Student student = new Student                    {                        StudentID = studentTmp.StudentID,                        StudentNo = studentTmp.BasicStudentEntity.StudentNo,                        Name = studentTmp.BasicStudentEntity.Name,                        ClassName = studentTmp.BasicStudentEntity.BasicClassEntity.ClassName ,                        GradeName = studentTmp.BasicStudentEntity.BasicClassEntity.BasicGradeEntity.GradeName,                        TrainDestination = studentTmp.BasicStudentEntity.TrainDestination,                        OrganizationName = studentTmp.BasicStudentEntity.BasicClassEntity.BasicOrganizationEntity.OrganizationName //学院                    };                    studentlist.Add(student);                }                TimeTable timetable = new TimeTable                {                    TimeTableID = item.TimeTableID,                    OnClassName=item.BasicOnClassEntity.OnClassName,                    EndWeek = item.EndWeek,                    StratWeek = item.StratWeek,                    Cycle = item.Cycle,                    OnClassID = item.BasicOnClassEntity.OnClassID,                    CourseName = item.BasicOnClassEntity.BasicCourseEntity.CourseName,                    StartSectionName = item.BasicSectionEntity.SectionName,                    EndSectionName = item.BasicSectionEntity1.SectionName,                    Week = item.Week,                    BuildingName = item.BasicRoomEntity.BasicBuildingEntity.BuildingName,                    RoomName = item.BasicRoomEntity.RoomName,                    CourseTypeName = item.BasicOnClassEntity.BasicCourseEntity.BasicCourseTypeEntity.CourseTypeName,                    CoursepropertyName = item.BasicOnClassEntity.BasicCourseEntity.BasicCoursepropertyEntity.CoursepropertyName,                    OrganizationName = item.BasicOnClassEntity.BasicCourseEntity.BasicOrganizationEntity.OrganizationName,                    teacherName = item.BasicOnClassEntity.BasicTeacherEntity.Name,                    SchoolYear = item.BasicOnClassEntity.BasicSchoolCalendarEntity.SchoolYear,                    Term=item.BasicOnClassEntity.BasicSchoolCalendarEntity.Term,                    Period = item.BasicOnClassEntity.BasicCourseEntity.Period,                    Credit = item.BasicOnClassEntity.BasicCourseEntity.Credit,                    studentSum = item.BasicOnClassEntity.TotalMember,                    studentList = studentlist                };                timetablelist.Add(timetable);            }            return timetablelist;        }</span>

             代码的实现到此为止，可是其中的思路和遇到问题时的心态回想起来比敲代码更加重要，因为查看详情这个问题在一开始做的时候确实没有头绪， 查完资料，看完前辈们的之后，然后会感觉无从下手，于是一开始的时候就会有些焦虑，消极，但是现在想想，一切的焦虑、心烦只能是为自己的问题火上焦油，根本起不到任何好的作用，还有就是在遇到问题时，用工具的技巧、意识的培养都很重要，当我让其他的同学来帮我调的时候，我发现自己欠缺的更多的是工具的使用技巧，所以说用好工具可以助自己一臂之力啊！
