export default {
  data() {
    return {
      list: [1, 2, 3, 4, 5],
      loading: false,
      finished: false
    };
  },
  methods: {
    loadMore() {
      if (this.list.length >= 200) {
        this.finished = true;
        return;
      }

      this.loading = true;
      setTimeout(() => {
        let lastNumber = this.list[this.list.length - 1];
        for (let i = 0; i < 5; i ++) {
          lastNumber += 1;
          this.list.push(lastNumber);
        }
        this.loading = false;
      }, 2500);
    },
    loadMoreUpper() {
      if (this.list[0] < 0) return;
