public void ChangeSubjectsSort(int templateId)
{
string subjectIds = ctx.Post("subjectIds");
string[] subjectIdArray = subjectIds.Split(',');
for (int i = 0; i < subjectIdArray.Length; i++)
{
Edu_QnSubject qnSubject = edu_QnSubjectService.findById<Edu_QnSubject>(int.Parse(subjectIdArray[i]));
qnSubject.Sort = i + 1;
Result result = edu_QnSubjectService.update(qnSubject); //保存
