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"},{id:5,text:"555555555"},]allpage=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=true;               }else if(currentpage==7){list=[{id:1,text:"3131"},{id:2,text:"3232"}]allpage=7nextpage=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>

pageInfo.vue:

<template><div class="page"><p>//模拟ajax数据 1-3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: 'pageInfo',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 1-3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=3nextpage=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=3nextpage=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=3nextpage=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>

pageNews.vue:

<template><div class="page"><p>模拟ajax数据 1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: 'pageNews',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页setTimeout(function(){        if(currentpage==1){list=[{id:1,text:"111111"},{id:2,text:"222222"},{id:3,text:"3333333333"}]allpage=1nextpage=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>

预览效果：

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'//注册组件
import divuePage from './divuePage.vue'
Vue.component('divue-page', divuePage)
//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)
})

pageHome.vue引用：

<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></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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=true;               }else if(currentpage==7){list=[{id:1,text:"3131"},{id:2,text:"3232"}]allpage=7nextpage=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>

效果预览：

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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=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=7nextpage=true;               }else if(currentpage==7){list=[{id:1,text:"3131"},{id:2,text:"3232"}]allpage=7nextpage=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！

八.完整代码

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'//注册组件
import divuePage from './divuePage.vue'
Vue.component('divue-page', divuePage)
//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)
})
