js代碼：

data () {
return {
all: 10, //總頁數
cur: 1,//當前頁碼
totalPage: 0,//當前條數
}
},
methods: {
//請求數據
dataListFn: function(index){
this.$axios.get("http://127.0.0.1:8090/demand/selectListByPage",
{
params:{
page: index,
limit:'10',
state: 0
}
}).then((res) => {
if(res.data.message == "success"){
this.dataList=[];
for(let i=0;i<res.data.data.length;i++){
this.dataList.push(res.data.data[i])
}
this.all = res.data.totalPage;//總頁數
this.cur = res.data.pageNum;
this.totalPage = res.data.totalPage;
}

});
},
//分頁
btnClick: function(data){//頁碼點擊事件
if(data != this.cur){
this.cur = data
}
//根據點擊頁數請求數據
this.dataListFn(this.cur.toString());
},
pageClick: function(){
//根據點擊頁數請求數據
this.dataListFn(this.cur.toString());
}
},
computed: {
//分頁
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){
