这篇文章主要介绍“vuejs2.0怎么实现分页组件”的相关知识，小编通过实际案例向大家展示操作过程，操作方法简单快捷，实用性强，希望这篇“vuejs2.0怎么实现分页组件”文章能帮助大家解决问题。
首先使用基础 Vue 构造器，创建一个“子类”,Vue.extend( options )
var barHtml = '<div class="page-bar">'+
'<ul>'+
'<li v-if="cur>1"><a v-on:click="cur--,pageClick()">上一页</a></li>'+
'<li v-if="cur==1"><a class="banclick">上一页</a></li>'+
'<li v-for="index in indexs" v-bind:class="{ active: cur == index}">'+
'<a v-on:click="btnclick(index)">{{ index }}</a>'+
'</li>'+
'<li v-if="cur!=all"><a v-on:click="cur++,pageClick()">下一页</a></li>'+
'<li v-if="cur == all"><a class="banclick">下一页</a></li>'+
'<li><a>共<i>{{all}}</i>页</a></li>'+
'</ul>'+
'</div>';
var navBar = Vue.extend({
template:barHtml,
props:['all','cur'],
computed: {
indexs: function(){
var left = 1;
var right = this.all;
var ar = [];
if(this.all>= 5){
if(this.cur > 3 && this.cur < this.all-2){
left = this.cur - 2
right = this.cur + 2
}else{
if(this.cur<=3){
left = 1
right = 5
}else{
right = this.all
left = this.all -4
}
}
}
while (left <= right){
ar.push(left)
left ++
}
return ar
}
},
methods: {
btnclick: function(data){
if(data != this.cur){
this.cur = data;
this.$emit('btn-click',data);
}
},
pageClick: function(){
this.$emit('btn-click',this.cur);
}
},
});
window.pagenav = navBar;这儿创建了一个全局的pagenav，可以在其它地方都可以调用。
html代码
<div id="page">
<vue-nav :cur.sync="cur" :all.sync="all" v-on:btn-click="listenDate"></vue-nav>
<p >{{msg}}</p>
</div>css代码
.page-bar{
margin:40px;
}
ul,li{
margin: 0px;
padding: 0px;
}
li{
list-style: none
}
.page-bar ul{
overflow: hidden;
}
.page-bar li{
float: left;
}
.page-bar li:first-child>a {
margin-left: 0px
}
.page-bar a{
display: block;
border: 1px solid #ddd;
text-decoration: none;
position: relative;
padding: 6px 12px;
margin-left: -1px;
line-height: 1.42857143;
color: #337ab7;
cursor: pointer
}
.page-bar a:hover{
background-color: #eee;
}
.page-bar a.banclick{
cursor:not-allowed;
}
.page-bar .active a{
color: #fff;
cursor: default;
background-color: #337ab7;
border-color: #337ab7;
}
.page-bar i{
font-style:normal;
color: #d44950;
margin: 0px 4px;
font-size: 12px;
}新建一个vue对象实例
var pageBar = new Vue({
el: '#page',
data: {
all: 8, //总页数
cur: 1,//当前页码
msg:''
},
components:{
'vue-nav':pagenav
},
watch: {
cur: function(oldValue , newValue){
console.log('监听cur前与后的值：');
console.log(arguments);
}
},
methods:{
listenDate:function(data){
this.cur = data;
this.msg = '你点击了'+data+ '页';
}
}
})简单的用js封装了一下分页组件。
实现效果
