vue2.0实现分页组件的实例代码
最近使用vue2.0重构项目, 需要实现一个分页的表格, 没有找到合适的分页组件, 就自己写了一个, 效果如下:
该项目是使用 vue-cli搭建的, 如果你的项目中没有使用webpack,请根据代码自己调整:
首先新建pagination.vue文件, 所有组件的代码都写在这里, 写这样的组件并没有什么太大的难度, 主要是解决父子组件之间值传递的问题
<template> <nav> <ul class="pagination"> <li :class="{'disabled': current == 1}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(current - 1)"> « </a></li> <li :class="{'disabled': current == 1}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(1)"> 首页 </a></li> <li v-for="p in grouplist" :class="{'active': current == p.val}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(p.val)"> {{ p.text }} </a> </li> <li :class="{'disabled': current == page}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(page)"> 尾页 </a></li> <li :class="{'disabled': current == page}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(current + 1)"> »</a></li> </ul> </nav> </template> <script type="es6"> export default{ data(){ return { current: this.currentPage } }, props: { total: {// 数据总条数 type: Number, default: 0 }, display: {// 每页显示条数 type: Number, default: 10 }, currentPage: {// 当前页码 type: Number, default: 1 }, pagegroup: {// 分页条数 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); } } } } </script> <style lang="less"> .pagination { overflow: hidden; display: table; margin: 0 auto; /*width: 100%;*/ height: 50px; li { float: left; height: 30px; border-radius: 5px; margin: 3px; color: #666; & :hover { background: #000; a { color: #fff; } } a { display: block; width: 30px; height: 30px; text-align: center; line-height: 30px; font-size: 12px; border-radius: 5px; text-decoration: none } } .active { background: #000; a { color: #fff; } } } </style>
使用时, 在父组件中引入, 代码如下:
<template>
<v-pagination :total="total" :current-page='current' @pagechange="pagechange"></v-pagination>
</template>
<script type="es6">
import pagination from '@/components/common/pagination/pagination'
export default{
data(){
return {
total: 150, // 记录总条数
display: 10, // 每页显示条数
current: 1, // 当前的页数
},
methods: {
pagechange:function(currentPage){
console.log(currentPage);
// ajax请求, 向后台发送 currentPage, 来获取对应的数据
}
},
components: {
'v-pagination': pagination,
}
}
</script>
至此, 一个基于 vue2.0 的分页组件就完成了
