一.准備工總

利用vue-cli和webpack如何快速搭建一個項目我們已經有過介紹：

為vue開發准備的一份es6語法筆記  https://my.oschina.net/tbd/blog/1541903

Vue.js構建項目筆記1:vue-cli  https://my.oschina.net/tbd/blog/1552953

Vue.js構建項目筆記2:vuejs+vue-router  https://my.oschina.net/tbd/blog/1553267

Vue.js構建項目筆記3:vuejs+vue-router +vuex  https://my.oschina.net/tbd/blog/1553518

至於vue的語法學習，官網讓你最快速掌握：https://cn.vuejs.org/v2/guide/

 

二.創建初始化項目

這里不在詳細說明，我們的分頁演示只需要vue和vue-router就可以了，我們直接構建項目和設置配置。

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 // （縮寫）相當於 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: '分頁組件：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>//模擬ajax數據 1-7頁</p>
  		<ul class="ull">
			<li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">內容：{{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="";

			//模擬ajax數據 1-7頁
			setTimeout(function(){

三.分頁靜態結構和樣式

divuePage.vue:

<template>
	<div class="DiReactPage">
		<div class="DiReactPage-btn">第一頁</div>
		<div class="DiReactPage-btn disable">上一頁</div>
		<div class="DiReactPage-page">
			<span class="active">1</span>

		<input class="DiReactPage-input" type="text" />
		<button class="DiReactPage-btn">跳轉</button>
	</div>
</template>

<script>
export default {
  name: 'divuePage',
  data () {
    return {
	  pages:[1,2,3,4,5]
    }
  },
  methods:{

})


new Vue({

四.分頁組件實現邏輯分析

我們分析一下如何實現我們的分頁組件：

從分頁組件考慮：

分頁組件需要顯示頁數，那么就需要傳遞給分頁組件總用多少頁這個狀態，

上一頁和下一頁存在不可用狀態，在第一頁上一頁不可用，所以要把當前所在頁數傳遞，同樣頁數的焦點位置也需要它判斷，

然后就是方法，我們頁數和按鈕的點擊都是發起請求，攜帶的參數就是當前點擊的頁數，

1.總頁數，當前所在頁，可在父組件傳遞進入

2.發起請求的方法可以通過組件交互通信實現

1的數據都是接口會返回給我們的，我們直接以屬性傳遞即可：

2的實現也很簡單，我們其實已經處理模擬使用過了：

我們只需要自定義事件，讓分頁組件$emit即可：

pageHome.vue:

<template>
  <div class="page">
  		<p>//模擬ajax數據 1-7頁</p>
  		<ul class="ull">
			<li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">內容：{{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="";
			//模擬ajax數據 1-7頁
			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(){
  		//模擬生成第一頁數據
  		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.分頁組件邏輯編寫

divuePage.vue我們接受了這些傳遞的內容，總頁數和當前所在頁，然后點擊第一頁觸發自定義事件，傳遞給父組件一個1，獲取第一頁數據：

<template>
	<div class="DiReactPage">
		<div class="DiReactPage-btn" v-on:click="clickFirst">第一頁</div>
		<div class="DiReactPage-btn disable">上一頁</div>
		<div class="DiReactPage-page">
			<span class="active">1</span>
			<span>2</span>
			<span>3</span>
			<span>4</span>
		</div>
		<div class="DiReactPage-btn">下一頁</div>
		<div class="DiReactPage-btn">最后一頁</div>
		<div class="DiReactPage-btn">總4頁</div>
		<input class="DiReactPage-input" type="text" />
		<button class="DiReactPage-btn">跳轉</button>
	</div>
</template>

<script>
export default {
  name: 'divuePage',
  props:["currentpage","allpage"],
  methods:{
  	clickFirst:function(){//點擊第一頁	
		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; }

1.頁數顯示

我們的首要工作就是把頁數顯示出來，我們已經接收了總頁數，其實這個問題很容易解決，我們設置一個計算屬性，屬性依據總頁數生成一個數組，從1到n即可：

顯示：

這樣還不夠健壯，還有一個就是總頁數5做分界線，大於5就顯示當前到后4個，

比如在第3頁，顯示：3 4 5 6 7

第2頁，顯示：2 3 4 5 6

好了我們加入一些小的邏輯判斷：

我們要給當前頁加一個類名標識，已經獲取當前的頁數了，我們加一個判斷就可以了，在v-for中：

我們在加入點擊事件，拿到點擊的item就是要請求后台數據的參數page:

定義這個方法：

<template>
	<div class="DiReactPage">
		<div class="DiReactPage-btn" v-on:click="clickFirst">第一頁</div>
		<div class="DiReactPage-btn disable">上一頁</div>

		<button class="DiReactPage-btn">跳轉</button>
	</div>
</template>

  	pages:function(){

	}
  },

2.第一頁和最后一頁處理

這個很簡單，只是傳遞page參數，我們已經獲取總頁數，直接設置即可！

3.上一頁和下一頁處理

這個對比第一頁需要加入特殊的處理，當前是第一頁，這個按鈕就不可用狀態，下一頁一樣的邏輯判斷當前是不是在最后一頁：

調用位置加入事件，在加一個是否可用的類名：

4.跳頁處理

這個我們獲取輸入框的值，直接調用，不過對輸入的內容必須有一些判斷限制：

加一個data:

使用位置：

5.顯示總頁數

這個是最簡單的：

 

六.分頁全部代碼和測試

divuePage.vue:

<template>
	<div class="DiReactPage">
		<div class="DiReactPage-btn" v-on:click="clickFirst">第一頁</div>
		<div class="DiReactPage-btn" v-on:click="clickPrev" v-bind:class="{disable:currentpage==1}">上一頁</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}">下一頁</div>
		<div class="DiReactPage-btn" v-on:click="clickLast">最后一頁</div>
		<div class="DiReactPage-btn">總{{allpage}}頁</div>
		<input class="DiReactPage-input" type="text" v-model="skipvalue" />
		<button class="DiReactPage-btn" v-on:click="clickSkip">跳轉</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(){//點擊第一頁	
		this.$emit("getajaxlist",1);
	},
	clickCurrent:function(item){
		this.$emit("getajaxlist",item);
	},
	clickLast:function(){//點擊最后一頁
		this.$emit("getajaxlist",this.allpage);
	},
	clickPrev:function(){//點擊上一頁
		if(this.currentpage-1<1){
			return false;
		}
		this.$emit("getajaxlist",this.currentpage-1);
	},
	clickNext:function(){//點擊下一頁
		if(this.currentpage+1>this.allpage){
			return false;
		}
		this.$emit("getajaxlist",this.currentpage+1);
	},
	clickSkip:function(){//點擊下一頁
		if(isNaN(this.skipvalue)){
			console.log("必須是數字")
			return false;
		}
		if(this.skipvalue<1 || this.skipvalue>this.allpage){
			console.log("超過范圍")
			return false;
		}
		this.$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>

 

我們現在在pageHome.vue做了使用，這個模擬數據包含7頁，我們在另外兩個組件也使用分頁組件，測試小於5頁和只有1頁的效果：

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

 

 

直接粘貼就可以在另外的組件使用。

只有1頁：

小於5頁：

測試沒有太大問題！

 

七.優化和改進建議

當然不是樣式的優化，這個需要設計的參與，我們還是顯示的優化和改進，比如：

我們是不是該有一個...

還有就是...

可以參考別的分頁效果，然后你可以不斷的改進！
