vue 实现分页
1 新建 pager.js 文件
/** * [pagination 分页组件] * @param {Number} total [数据总条数] * @param {Number} display [每页显示条数 default:10] * @param {Number} current [当前页码 default:1] * @param {Number} pagegroup [分页条数(奇数) default:5] * @param {Event} pagechange [页码改动时 dispatch ] * @return {[type]} [description] */ Vue.component('pagination', { template: '#template_pagination', props: { total: { // 数据总条数 type: Number, default: 0 }, display: { // 每页显示条数 type: Number, default: 10 }, current: { // 当前页码 type: Number, default: 1 }, pagegroup: { // 分页条数 -- 奇数 type: Number, default: 5, coerce: function (v) { v = v > 0 ? v : 5; return v % 2 === 1 ? v : v + 1; } } }, computed: { page: function () { // 总页数 return Math.ceil(this.total / this.display); }, grouplist: function () { // 获取分页页码 var len = this.page, temp = [], list = [], count = Math.floor(this.pagegroup / 2), center = this.current; if (len <= this.pagegroup) { while (len--) { temp.push({ text: this.page - len, val: this.page - len }); }; return temp; } while (len--) { temp.push(this.page - len); }; var idx = temp.indexOf(center); (idx < count) && (center = center + count - idx); (this.current > this.page - count) && (center = this.page - count); temp = temp.splice(center - count - 1, this.pagegroup); do { var t = temp.shift(); list.push({ text: t, val: t }); } while (temp.length); if (this.page > this.pagegroup) { (this.current > count + 1) && list.unshift({ text: '...', val: list[0].val - 1 }); (this.current < this.page - count) && list.push({ text: '...', val: list[list.length - 1].val + 1 }); } return list; } }, methods: { setCurrent: function (idx) { if (this.current != idx && idx > 0 && idx < this.page + 1) { this.current = idx; this.$emit('pagechange', this.current); } } } });
