Vue SPA应用中使用Layer的iframe 弹出层,并且传值

layer.open({
           type: 2,
           area: [‘840px‘, ‘550px‘],
           fixed: false, //不固定
           maxmin: true,
           title:title,
           content:url,
       });

     var index = parent.layer.getFrameIndex(window.name); //获取窗口索引

                    parent.app.UserCheckCount=this.UserCheckCount;
                    parent.app.UserCheckList=this.UserCheckList;
                    parent.app.QuestionSelectList=this.QuestionSelectList;


                    parent.app.FatherQuestionList=this.QuestionSelectList;
                    parent.app.FatherQuestionMake();

                    console.log(parent.app.QuestionList);
                    parent.app.QuestionSelectKey=this.QuestionSelectKey;
                    parent.app.QuesctionPageMake();

                    parent.layer.close(index);
