使用Vue做双向绑定的时候，可能经常会用到分页功能
接下来我们来封装一个分页组件
先定义样式文件 pagination.css
ul, li { margin: 0px; padding: 0px; } .page-bar { -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; } .page-button-disabled { color:#ddd !important; } .page-bar li { list-style: none; display: inline-block; } .page-bar li:first-child > a { margin-left: 0px; } .page-bar a { border: 1px solid #ddd; text-decoration: none; position: relative; float: left; padding: 6px 12px; margin-left: -1px; line-height: 1.42857143; color: #337ab7; cursor: pointer; } .page-bar a:hover { background-color: #eee; } .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; }
js文件 pagination.js
(function (vue) { // html模板信息 var template = '<div> \ <ul> \ <li><a v-on:click="prvePage(cur)">上一页</a></li> \ <li v-for="index in indexs" v-bind:class="{ active: cur == index }"> \ <a v-on:click="btnClick(index)">{{ index < 1 ? "..." : index }}</a> \ </li> \ <li><a v-on:click="nextPage(cur)">下一页</a></li> \ </ul> \ </div>' var pagination = vue.extend({ template: template, props: ['cur', 'all'], computed: { indexs: function () { var left = 1 var right = this.all var ar = [] if (this.all >= 11) { if (this.cur > 5 && this.cur < this.all - 4) { left = this.cur - 5 right = this.cur + 4 } else { if (this.cur <= 5) { left = 1 right = 10 } else { right = this.all left = this.all - 9 } } } while (left <= right) { ar.push(left) left++ } if (ar[0] > 1) { ar[0] = 1; ar[1] = -1; } if (ar[ar.length - 1] < this.all) { ar[ar.length - 1] = this.all; ar[ar.length - 2] = 0; } return ar } }, methods: { // 页码点击事件 btnClick: function (data) { if (data < 1) return; if (data != this.cur) { this.cur = data this.$dispatch('btn-click', data) } }, // 下一页 nextPage: function (data) { if (this.cur >= this.all) return; this.btnClick(this.cur + 1); }, // 上一页 prvePage: function (data) { if (this.cur <= 1) return; this.btnClick(this.cur - 1); }, // 设置按钮禁用样式 setButtonClass: function (isNextButton) { if (isNextButton) { return this.cur >= this.all ? "page-button-disabled" : "" } else { return this.cur <= 1 ? "page-button-disabled" : "" } } } }) vue.Pagination = pagination })(Vue)
pagination分页组件就封装好了，需要使用的时候，引入以上两个文件即可
接下来我们测试下效果
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> <title></title> <script src="https://www.jb51.net/article/vue.js"></script> <link href="https://www.jb51.net/pagination.css" /> <script src="https://www.jb51.net/pagination.js"></script> </head> <body> <div> <vue-pagination :cur.sync="cur" :all.sync="all" v-on:btn-click="listen"></vue-pagination> <p>{{msg}}</p> </div> <script type="text/javascript"> var app = new Vue({ el: '#app', data: { // 当前页码 cur: 1, // 总页数 all: 100, msg: '' }, components: { // 引用组件 'vue-pagination': Vue.Pagination }, methods: { listen: function (data) { // 翻页会触发此事件 this.msg = '当前页码：' + data } } }) </script> </body> </html>
最终效果
页码切换事件在listen中处理即可
