el: '#demoList',
data: {
items: [{
"id": 1,
"name": "Tom"
}, {
"id": 2,
"name": "Kate"
}, {
"id": 3,
"name": "Jack"
}, {
"id": 4,
"name": "Jill"
}, {

loading: false,
order: 1,
searchText: null,
ccn: null,
currentPage: 0,
itemsPerPage: 2,
resultCount: 0
},
computed: {
totalPages: function() {
console.log(Math.ceil(this.resultCount / this.itemsPerPage) + "totalPages");
return Math.ceil(this.resultCount / this.itemsPerPage);

}
},
methods: {
setPage: function(pageNumber) {
this.currentPage = pageNumber;
console.log(pageNumber);
}
},
filters: {
paginate: function(list) {
this.resultCount = this.items.length;
console.log(this.resultCount + " Result count");
console.log(this.currentPage + " current page");
console.log(this.itemsPerPage + " items per page");
console.log(this.totalPages + " Total pages 2");
if (this.currentPage >= this.totalPages) {
this.currentPage = Math.max(0, this.totalPages - 1);
}
var index = this.currentPage * this.itemsPerPage;
console.log(index + " index");
console.log(this.items.slice(index, index + this.itemsPerPage));
return this.items.slice(index, index + this.itemsPerPage);
}
}
});

a {

}
.current {

}
ul {
padding: 0;
list-style-type: none;

Answer

Check out this code:

https://jsfiddle.net/os7hp1cy/48/

html:

<ul>
    <li v-for="pageNumber in totalPages" 
        v-if="Math.abs(pageNumber - currentPage) < 3 || pageNumber == totalPages - 1 || pageNumber == 0">
    <a href="#" @click="setPage(pageNumber)"  
       :class="{current: currentPage === pageNumber, last: (pageNumber == totalPages - 1 && Math.abs(pageNumber - currentPage) > 3), first:(pageNumber == 0 && Math.abs(pageNumber - currentPage) > 3)}">
       {{ pageNumber+1 }}</a>
    </li>
</ul>

css:

a.first::after {
  content:'...'
}

a.last::before {
  content:'...'
}

Basically, it only shows pagination that is within 2 pages of the current page. Then it will also show page 1 and the last page, and will put "..." before or after the number with CSS. So if you are on page 10, it will show:

1... 8 9 10 11 12 ...21
