        let selectPaperCheckBox = this.$store.state.selectPaperCheckBox;
        //question 选择的试题id
        let question = selectPaperCheckBox.question;
        //paper 对象
        let paper = selectPaperCheckBox.paper;
....
          let filter = [];
              contentListElement.questionIdList.forEach(it => {
                filter.push(it.questionId);
              })
              paper.paperMap.set(contentListElement.id + '', filter);
              //查询设置 map
              paper.paperMap=new Map(paper.paperMap)
