VueJs如何使用限制器和范围进行分页..? [英] VueJs how to make pagination with limiter and range..?
问题描述
我有这样的代码:
I have code like this :
var demoList = new Vue({
el: '#demoList',
data: {
items: [{
"id": 1,
"name": "Tom"
}, {
"id": 2,
"name": "Kate"
}, {
"id": 3,
"name": "Jack"
}, {
"id": 4,
"name": "Jill"
}, {
"id": 5,
"name": "aa"
}, {
"id": 6,
"name": "bb"
}, {
"id": 7,
"name": "cc"
}, {
"id": 8,
"name": "dd"
}, {
"id": 1,
"name": "Tom"
}, {
"id": 2,
"name": "Kate"
}, {
"id": 3,
"name": "Jack"
}, {
"id": 4,
"name": "Jill"
}, {
"id": 5,
"name": "aa"
}, {
"id": 6,
"name": "bb"
}, {
"id": 7,
"name": "cc"
}, {
"id": 8,
"name": "dd"
}, ],
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 {
color: #999;
}
.current {
color: red;
}
ul {
padding: 0;
list-style-type: none;
}
li {
display: inline;
margin: 5px 5px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.16/vue.js"></script>
<div id="demoList">
<div class="containerTable">
<table class="table">
<thead>
<tr class="header">
<th>
<div><a @click="sortvia('provider_name')">Provider</a>
</div>
</th>
</tr>
</thead>
<tbody>
<tr v-for="item in items | paginate">
<td>{{item.name}}</td>
</tr>
</tbody>
</table>
</div>
<ul>
<li v-for="pageNumber in totalPages">
<a href="#" @click="setPage(pageNumber)">{{ pageNumber+1 }}</a>
</li>
</ul>
</div>
我一直在尝试使用 vuejs 创建寻呼机,所以我想知道是否有人可以指定一个示例,说明如何在可能的情况下制作这样的寻呼机 "1-2-3-4-5 ... 55" ??,再次感谢您的帮助.

推荐答案
查看这段代码:
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:'...'
}
基本上,它只显示当前页面 2 页内的分页.然后它还会显示第 1 页和最后一页,并将 "..."
放在带有 CSS 的数字之前或之后.因此,如果您在第 10 页,它将显示:
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
