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 class="page-bar">            <ul>             <li><a class="{{ setButtonClass(0) }}" 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 class="{{ setButtonClass(1) }}" 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="/UploadFiles/2021-04-02/vue.js">

最终效果
