Vue 实现一个分页组件
实现分页组件要分三个部分
样式，逻辑，和引用
首先新建一个vue文件用来承载组件内容
第一步：构建样式
<template>
<nav>
<ul class="pagination">
<li :class="{'disabled': current == 1}"><a href="javascript:;" @click="setCurrent(current - 1)"> <img src="../../../assets/btnleft.png" alt=""> </a></li>
<li v-for="(p,index) in grouplist" :class="{'active': current == p.val}" :key="index"><a href="javascript:;" @click="setCurrent(p.val)"> {{ p.text }} </a>
</li>
<li :class="{'disabled': current == page}"><a href="javascript:;" @click="setCurrent(current + 1)"> <img src="../../../assets/btnright.png" alt=""></a></li>
</ul>
</nav>
</template>
<style scope="scope">
.pagination {
overflow: hidden;
display: table;
margin: 0 auto;
height: 50px;
}
.pagination li {
float: left;
height: 30px;
border-radius: 5px;
margin: 3px;
}
.pagination li img{
width:100%;
height:100%;
}
.pagination li:hover{
background: #1E7FED;
}
.pagination li:hover a{
color: #fff;
}
.pagination a {
display: block;
width: 30px;
height: 30px;
text-align: center;
line-height: 30px;
font-size: 12px;
border-radius: 5px;
text-decoration: none;
border:1px solid rgba(221,221,221,1);
color: #666666;
}
.pagination .active {
background: #1E7FED !important;
}
.active >a{
color:white;
}
</style>
第二步:编写逻辑
<script>
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: 20
},
currentPage: {// 当前页码
type: Number,
default: 1
},
pagegroup: {// 分页条数
type: Number,
default: 20,
coerce: function (v) {
v = v > 0 ? v : 20;
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>
第三步：引用组件
1.在父组件中引入并注册
total:0, // 记录总条数
display: 10, // 每页显示条数
current: 1, // 当前的页数
3.挂载
