props定义三个属性：当前页码，当前页显示数量，总数量
computed定义了一个计算方法：获取总数量/当前页显示数量，向上取整，默认取10个
methods定义了一个根据页码跳转方法：最终用于触发change事件，$emit用于抛出自定义事件，组件外可以捕获当前定义的change事件
html组件显示：
复制代码 代码如下:
<pagination :page-num="criteria.page.num" :page-size="criteria.page.size" :total-item-count="itemsCount" v-on:change="skiptoPage"></pagination>
以上的值为自己传入的值
let vm = new Vue({ el: '#app', data: { criteria: { keyword: '', page: { num: 1, size: 10 } }, itemsCount: 0 }, methods: { skiptoPage: function (num) { this.criteria.page.num = num; } } });
以上方法是自定义事件change的方法，你们可以自己去修改内容。
