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>

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！
3.上一页和下一页处理
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>
<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);
},
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);
}
}
}
</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：
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！
