首先，做出来的效果如图所示，具体的Ajax请求数据可以写在点击函数中
分页效果算是比较费脑子的，里面计算有些麻烦，本文上完整代码，一起学习进步
<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>
<!--当前页背景色为蓝色-->
<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>
难点就是IF嵌套语句
1、每次显示5个数据，如果大于3，范围从3到6，如果到达7，那么下边加2变成9，已经超过最大的范围值，所以最大范围到6
2、如果是大于6，那么最大值就是最大值，最小变成all-4
3、如果3以内，默认不跳动
var pageBar = new Vue({
el: '.page-bar',
data: {
all: 8, //总页数
cur: 1//当前页码
},
watch: {
cur: function(oldValue , newValue){
console.log(arguments);
}
},
methods: {
btnClick: function(data){
if(data != this.cur){
this.cur = data;
}
},
pageClick: function(){
console.log('现在在'+this.cur+'页');
}
},
computed: {
indexs: function(){
var left = 1;
var right = this.all;
var ar = [];
if(this.all>= 5){
//这里最大范围从3到6，如果到达7，那么下边加2变成9，已经超过最大的范围值
if(this.cur > 3 && this.cur < this.all-1){
//以4为参考基准，左面加2右边加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 ++
}
console.log(ar);
return ar
}
}
})
