vue里面怎么使用String字符串操作的includes

Question

报错：

代码：

searchCourse:(data)=>{
            if (data.length !== 0) {
                for (let i = 0;i < data.length;i++) {
                    let titleState = data[i].videoTitle.includes(this.searchKey);
                    let conState = data[i].videoInfo.includes(this.searchKey);
                    if (titleState){
                        if (this.videoSearchResultArr.length !== 0) {
                            for (let v = 0;v < vm.videoSearchResultArr.length;v++) {
                                if (data[i].videoTitle !== vm.videoSearchResultArr[v].videoTitle && data[i].videoInfo !== vm.videoSearchResultArr[v].videoInfo) {
                                    vm.videoSearchResultArr.push(data[i]);
                                }
                            }
                        }else {
                            vm.videoSearchResultArr.push(data[i]);
                        }
                    }
                    if (conState) {
                        if (this.videoSearchResultArr.length !== 0) {
                            for (let v = 0;v < vm.videoSearchResultArr.length;v++) {
                                if (data[i].videoTitle !== vm.videoSearchResultArr[v].videoTitle && data[i].videoInfo !== vm.videoSearchResultArr[v].videoInfo) {
                                    vm.videoSearchResultArr.push(data[i]);
                                }
                            }
                        }else {
                            vm.videoSearchResultArr.push(data[i]);
                        }
                    }
                }
            }
        }

不知道为什么一直用不了这个关键字，原生js是没问题的，但一搭载vue框架就当机了

打印data数据然后控制台展开数据截张图看下，看includes是字符串的方法，属性拼写出错会导致获取不到数据为undefined会出错

searchCourse:(data)=>{
console.log(data)
