<script>
import { IndexBar, IndexAnchor } from "vant";
export default {
  components: {
    "van-index-bar": IndexBar,
    "van-index-anchor": IndexAnchor
  },
  data() {
    return {
      indexList: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    };
  },
  methods: {
    goView(val) {
      document.querySelector("#" + val).scrollIntoView({
        behavior: "smooth",
        block: "end",
        inline: "nearest"
      });
