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">

<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>

</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！郑重声明：本站内容如果来自互联网及其他传播媒体，其版权均属原媒体及文章作者所有。转载目的在于传递更多信息及用于网络分享，并不代表本站赞同其观点和对其真实性负责，也不构成任何其他建议。
