基础用法

<script> 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; this.list.unshift(-1); } }, computed: { isWaterfallDisabled: function() { return this.loading || this.finished; } } }; </script> <style> .waterfall { max-height: 300px; overflow: scroll; } </style>

<div class="waterfall">
  <div
