Vue.js分页组件实现：diVuePagination的使用详解

时间：2021-03-25 09:20:28|栏目：vue|点击：次

一.介绍

Vue.js 是什么

Vue (读音 /vjuː/，类似于 view) 是一套用于构建用户界面的渐进式框架。与其它大型框架不同的是，Vue 被设计为可以自底向上逐层应用。Vue 的核心库只关注视图层，不仅易于上手，还便于与第三方库或既有项目整合。另一方面，当与现代化的工具链以及各种支持类库结合使用时，Vue 也完全能够为复杂的单页应用提供驱动。

二.创建初始化项目

这里不在详细说明，我们的分页演示只需要vue和vue-router就可以了，我们直接构建项目和设置配置。

main.js:

import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import pageHome from './pageHome.vue'
import pageNews from './pageNews.vue'
import pageInfo from './pageInfo.vue'
//路由配置
Vue.use(VueRouter);
var routes = [
 { path: '/', component: pageHome},
 { path: '/pageNews', component: pageNews},
 { path: '/pageInfo', component: pageInfo}
]
var router = new VueRouter({
 routes: routes // （缩写）相当于 routes: routes
})
new Vue({
 el: '#app',
 router,
 render: h => h(App)
})

App.vue:

<template>
 <div id="app">
 <h3>{{msg}}</h3>
 <ul>
 <li><router-link to="/">pageHome</router-link></li>
 <li><router-link to="/pageNews">pageNews</router-link></li>
 <li><router-link to="/pageInfo">pageInfo</router-link></li>
 </ul>
 <div>
 <router-view></router-view>
 </div>
 </div>
</template>
<script>
export default {
 name: 'app',
 data () {
 return {
 msg: '分页组件：DiVuePage '
 }
 }
}
</script>
<style>
#app {
 font-family: 'Avenir', Helvetica, Arial, sans-serif;
 -webkit-font-smoothing: antialiased;
 -moz-osx-font-smoothing: grayscale;
 text-align: center;
 color: #2c3e50;
 margin-top: 60px;
}
</style>

pageHome.vue:

<template>
 <div class="page">
 <p>//模拟ajax数据 1-7页</p>
 <ul class="ull">
 <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容：{{item.text}}</span></li>
 </ul>
 </div>
</template>
<script>
export default {
 name: 'pageHome',
 data () {
 return {
 currentpage:0,
 list: [],
 allpage:"",
 nextpage:false
 }
 },
 methods:{
 getajaxlist:function(currentpage){
 var that=this;
 var list=[];
 var allpage="";
 var nextpage="";
 //模拟ajax数据 1-7页
 setTimeout(function(){ 
 if(currentpage==1){
 list=[
 {id:1,text:"111111"},
 {id:2,text:"222222"},
 {id:3,text:"3333333333"},
 {id:4,text:"44444444444"},

 ]
 allpage=7
 nextpage=false; 
 };
 that.currentpage=currentpage;
 that.list=list;
 that.allpage=allpage;
 that.nextpage=nextpage;
 },200); 
 }
 },
 created:function(){
 //模拟生成第一页数据
 this.getajaxlist(1);
 }
}
</script>
<style>
 ul{ list-style:none;}

三.分页静态结构和样式

divuePage.vue:

<template>
 <div class="DiReactPage">
 <div class="DiReactPage-btn">第一页</div>
 <div class="DiReactPage-btn disable">上一页</div>
 <div class="DiReactPage-page">
 <span class="active">1</span>
 <span>2</span>
 <span>3</span>
 <span>4</span>
 </div>
 <div class="DiReactPage-btn">下一页</div>
 <div class="DiReactPage-btn">最后一页</div>
 <div class="DiReactPage-btn">总4页</div>
 <input class="DiReactPage-input" type="text" />
 <button class="DiReactPage-btn">跳转</button>
 </div>
</template>
<script>
export default {
 name: 'divuePage',
 data () {
 return {
 pages:[1,2,3,4,5]
 }
 },
 methods:{
 }
}
</script>
<style>
 .DiReactPage{ height:30px; line-height:30px; text-align:center;}
 .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;}
 .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;}
 .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;}
 .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;}
 .DiReactPage .DiReactPage-page span.active{ color:#09F; }
 .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; }
</style>

main.js注册：

import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import pageHome from './pageHome.vue'
import pageNews from './pageNews.vue'
import pageInfo from './pageInfo.vue'

]
var router = new VueRouter({
 routes: routes // （缩写）相当于 routes: routes
})
new Vue({
 el: '#app',
 router,
 render: h => h(App)

 .r{float:left;width:600px;}
</style>

四.分页组件实现逻辑分析

我们分析一下如何实现我们的分页组件：

从分页组件考虑：

分页组件需要显示页数，那么就需要传递给分页组件总用多少页这个状态，

上一页和下一页存在不可用状态，在第一页上一页不可用，所以要把当前所在页数传递，同样页数的焦点位置也需要它判断，

然后就是方法，我们页数和按钮的点击都是发起请求，携带的参数就是当前点击的页数，

1.总页数，当前所在页，可在父组件传递进入

2.发起请求的方法可以通过组件交互通信实现

1的数据都是接口会返回给我们的，我们直接以属性传递即可：

2的实现也很简单，我们其实已经处理模拟使用过了：

我们只需要自定义事件，让分页组件$emit即可：

pageHome.vue:

<template>
 <div class="page">
 <p>//模拟ajax数据 1-7页</p>
 <ul class="ull">
 <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容：{{item.text}}</span></li>
 </ul>
 <divue-page v-bind:currentpage="currentpage" v-bind:allpage="allpage" v-on:getajaxlist="getajaxlist"></divue-page>
 </div>
</template>
<script>
export default {
 name: 'pageHome',
 data () {
 return {
 currentpage:0,
 list: [],
 allpage:"",
 nextpage:false
 }
 },
 methods:{
 getajaxlist:function(currentpage){
 var that=this;
 var list=[];
 var allpage="";
 var nextpage="";
 //模拟ajax数据 1-7页
 setTimeout(function(){ 
 if(currentpage==1){
 list=[
 {id:1,text:"111111"},
 {id:2,text:"222222"},
 {id:3,text:"3333333333"},
 {id:4,text:"44444444444"},
 {id:5,text:"555555555"},
 ]
 allpage=7
 nextpage=true;
 }else if(currentpage==2){
 list=[
 {id:1,text:"66666666"},
 {id:2,text:"7777777777"},
 {id:3,text:"8888888888"},
 {id:4,text:"99999999999"},
 {id:5,text:"101010"},
 ]
 allpage=7
 nextpage=true; 
 }else if(currentpage==3){
 list=[
 {id:1,text:"111111111111111"},
 {id:2,text:"121212"},
 {id:3,text:"131313"},
 {id:4,text:"141414"},
 {id:5,text:"15515"},
 ]
 allpage=7
 nextpage=true; 
 }else if(currentpage==4){
 list=[
 {id:1,text:"161616"},
 {id:2,text:"171717"},
 {id:3,text:"181818"},
 {id:4,text:"191919"},
 {id:5,text:"202020"},
 ]
 allpage=7
 nextpage=true; 
 }else if(currentpage==5){
 list=[
 {id:1,text:"2121"},
 {id:2,text:"22222"},
 {id:3,text:"232323"},
 {id:4,text:"242424"},
 {id:5,text:"252525"},
 ]
 allpage=7
 nextpage=true; 
 }else if(currentpage==6){
 list=[
 {id:1,text:"2626"},
 {id:2,text:"2727"},
 {id:3,text:"2828"},
 {id:4,text:"2929"},
 {id:5,text:"3030"},
 ]
 allpage=7
 nextpage=true; 
 }else if(currentpage==7){
 list=[
 {id:1,text:"3131"},
 {id:2,text:"3232"}
 ]
 allpage=7
 nextpage=false; 
 };
 that.currentpage=currentpage;
 that.list=list;
 that.allpage=allpage;
 that.nextpage=nextpage;
 },200); 
 }
 },
 created:function(){
 //模拟生成第一页数据
 this.getajaxlist(1);
 }
}
</script>
<style>
 ul{ list-style:none;}
 ull{ margin:100px auto; width:1000px;line-height:30px;}
 li{height:30px;}
 .l{float:left;width:300px;}
 .r{float:left;width:600px;}
</style>

五.分页组件逻辑编写

divuePage.vue我们接受了这些传递的内容，总页数和当前所在页，然后点击第一页触发自定义事件，传递给父组件一个1，获取第一页数据：

<template>
 <div class="DiReactPage">
 <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div>
 <div class="DiReactPage-btn disable">上一页</div>
 <div class="DiReactPage-page">
 <span class="active">1</span>
 <span>2</span>
 <span>3</span>
 <span>4</span>
 </div>
 <div class="DiReactPage-btn">下一页</div>
 <div class="DiReactPage-btn">最后一页</div>
 <div class="DiReactPage-btn">总4页</div>
 <input class="DiReactPage-input" type="text" />
 <button class="DiReactPage-btn">跳转</button>
 </div>
</template>
<script>
export default {
 name: 'divuePage',
 props:["currentpage","allpage"],
 methods:{
 clickFirst:function(){//点击第一页 
 this.$emit("getajaxlist",1);
 }
 }
}
</script>
<style>
 .DiReactPage{ height:30px; line-height:30px; text-align:center;}
 .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;}
 .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;}
 .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;}
 .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;}
 .DiReactPage .DiReactPage-page span.active{ color:#09F; }
 .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; }
</style>

1.页数显示

我们的首要工作就是把页数显示出来，我们已经接收了总页数，其实这个问题很容易解决，我们设置一个计算属性，属性依据总页数生成一个数组，从1到n即可：

显示：

这样还不够健壮，还有一个就是总页数5做分界线，大于5就显示当前到后4个，

比如在第3页，显示：3 4 5 6 7

第2页，显示：2 3 4 5 6

好了我们加入一些小的逻辑判断：

我们要给当前页加一个类名标识，已经获取当前的页数了，我们加一个判断就可以了，在v-for中：

我们在加入点击事件，拿到点击的item就是要请求后台数据的参数page:

定义这个方法：

完整代码：

<template>
 <div class="DiReactPage">
 <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div>
 <div class="DiReactPage-btn disable">上一页</div>
 <div class="DiReactPage-page">
 <span v-for="(item,index) in pages" v-bind:class="{active:currentpage==item}" v-on:click="clickCurrent(item)">{{item}}</span>
 </div>
 <div class="DiReactPage-btn">下一页</div>
 <div class="DiReactPage-btn">最后一页</div>
 <div class="DiReactPage-btn">总4页</div>
 <input class="DiReactPage-input" type="text" />
 <button class="DiReactPage-btn">跳转</button>
 </div>
</template>
<script>
export default {
 name: 'divuePage',
 computed:{
 pages:function(){
 var arr=[];
 if(this.allpage>5){
 if(this.currentpage+5>this.allpage){
 for(var i=this.currentpage;i<=this.allpage;i++){
 arr.push(i);
 };
 }else{
 for(var i=this.currentpage;i<this.currentpage+5;i++){
 arr.push(i);
 };
 };
 }else{
 for(var i=1;i<=this.allpage;i++){
 arr.push(i);
 };
 }
 return arr;
 }
 },
 props:["currentpage","allpage"],
 methods:{
 clickFirst:function(){//点击第一页 
 this.$emit("getajaxlist",1);
 },
 clickCurrent:function(item){
 this.$emit("getajaxlist",item);
 }
 }
}
</script>
<style>
 .DiReactPage{ height:30px; line-height:30px; text-align:center;}
 .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;}
 .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;}
 .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;}
 .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;}
 .DiReactPage .DiReactPage-page span.active{ color:#09F; }
 .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; }
</style>

效果测试：

2.第一页和最后一页处理

这个很简单，只是传递page参数，我们已经获取总页数，直接设置即可！

这个对比第一页需要加入特殊的处理，当前是第一页，这个按钮就不可用状态，下一页一样的逻辑判断当前是不是在最后一页：

调用位置加入事件，在加一个是否可用的类名：

全部代码：

<template>

 .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; }
</style>

效果测试：

4.跳页处理

这个我们获取输入框的值，直接调用，不过对输入的内容必须有一些判断限制：

加一个data:

使用位置：

5.显示总页数

这个是最简单的：

六.分页全部代码和测试

divuePage.vue:

<template>
 <div class="DiReactPage">
 <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div>
 <div class="DiReactPage-btn" v-on:click="clickPrev" v-bind:class="{disable:currentpage==1}">上一页</div>
 <div class="DiReactPage-page">
 <span v-for="(item,index) in pages" v-bind:class="{active:currentpage==item}" v-on:click="clickCurrent(item)">{{item}}</span>
 </div>
 <div class="DiReactPage-btn" v-on:click="clickNext" v-bind:class="{disable:currentpage==allpage}">下一页</div>
 <div class="DiReactPage-btn" v-on:click="clickLast">最后一页</div>
 <div class="DiReactPage-btn">总{{allpage}}页</div>
 <input class="DiReactPage-input" type="text" v-model="skipvalue" />
 <button class="DiReactPage-btn" v-on:click="clickSkip">跳转</button>
 </div>
</template>
<script>
export default {
 name: 'divuePage',
 computed:{
 pages:function(){
 var arr=[];
 if(this.allpage>5){
 if(this.currentpage+5>this.allpage){
 for(var i=this.currentpage;i<=this.allpage;i++){
 arr.push(i);
 };
 }else{
 for(var i=this.currentpage;i<this.currentpage+5;i++){
 arr.push(i);
 };
 };
 }else{
 for(var i=1;i<=this.allpage;i++){
 arr.push(i);
 };
 }
 return arr;
 }
 },
 data:function(){
 return {
 skipvalue:""
 }
 },
 props:["currentpage","allpage"],
 methods:{
 clickFirst:function(){//点击第一页 
 this.$emit("getajaxlist",1);
 },
 clickCurrent:function(item){
 this.$emit("getajaxlist",item);
 },
 clickLast:function(){//点击最后一页
 this.$emit("getajaxlist",this.allpage);
 },
 clickPrev:function(){//点击上一页
 if(this.currentpage-1<1){
 return false;
 }
 this.$emit("getajaxlist",this.currentpage-1);
 },
 clickNext:function(){//点击下一页
 if(this.currentpage+1>this.allpage){
 return false;
 }
 this.$emit("getajaxlist",this.currentpage+1);
 },
 clickSkip:function(){//点击下一页
 if(isNaN(this.skipvalue)){
 console.log("必须是数字")
 return false;
 }
 if(this.skipvalue<1 || this.skipvalue>this.allpage){
 console.log("超过范围")
 return false;
 }
 this.$emit("getajaxlist",this.skipvalue);
 }
 }
}
</script>
<style>
 .DiReactPage{ height:30px; line-height:30px; text-align:center;}
 .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;}
 .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;}
 .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;}
 .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;}
 .DiReactPage .DiReactPage-page span.active{ color:#09F; }
 .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; }
</style>

我们现在在pageHome.vue做了使用，这个模拟数据包含7页，我们在另外两个组件也使用分页组件，测试小于5页和只有1页的效果：

<divue-page v-bind:currentpage="currentpage" v-bind:allpage="allpage" v-on:getajaxlist="getajaxlist"></divue-page>

直接粘贴就可以在另外的组件使用。

只有1页：

小于5页：

测试没有太大问题！

七.优化和改进建议

当然不是样式的优化，这个需要设计的参与，我们还是显示的优化和改进，比如：

我们是不是该有一个...

还有就是...

可以参考别的分页效果，然后你可以不断的改进！
