1.定义总数据分页、获取指定页数据的方法
getListSegment(list) { // list为总的数据 const len = list.length; const n = this.pageSize; const lineNum = len % n === 0 ? len / n : Math.floor(len / n + 1); const res = []; for (let i = 0; i < lineNum; i++) { let temp = list.slice(i * n, i * n + n); res.push(temp); } this.listSegment = res; // listSegment为已分好页的二维数组},getListByPage() { //获取每页的数据并页数+1，获取不到返回[] const data = this.listSegment[this.pageNo - 1]; this.pageNo++; if (data) { return data; } else { return []; }}
2.调用方法
this.listOrign = res.data; //res.data为后端返回的总数组this.getListSegment(this.listOrign);this.pageNo = 1;const data = this.getListByPage();this.list = data; // 最终显示的数组
