Vue.js分页组件实现:diVuePagination的使用详解(7)

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 {

 computed:{
 pages:function(){
 var arr=[];
 if(this.allpage>5){

 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);
 },
