vue中对element的分页组件的封装

在vue中使用分页，一般都做个封装来全局化，对组件进行复用。

1、封装。（直接copy就可以使用）

在components文件夹下创建一个pagination文件夹，并新建一个文件index.vue,内容如下：

/** index.vue*/
<template>
  <div :class="{'hidden':hidden}" class="pagination-container">
    <el-pagination
      :background="background"
      :current-page.sync="currentPage"
      :page-size.sync="pageSize"
      :layout="layout"
      :page-sizes="pageSizes"
      :total="total"
      v-bind="$attrs"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"/>
  </div>
</template>

<script>
import { scrollTo } from '@/utils/scrollTo'

export default {
  name: 'Pagination',
  props: {
    total: {
      required: true,
      type: Number
    },
    page: {
      type: Number,
      default: 1
    },
    limit: {
      type: Number,
      default: 20
    },
    pageSizes: {
      type: Array,
      default() {
        return [10, 20, 30, 50]
      }
    },
    layout: {
      type: String,
      default: 'total, sizes, prev, pager, next, jumper'
    },
    background: {
      type: Boolean,
      default: true
    },
    autoScroll: {
      type: Boolean,
      default: true
    },
    hidden: {
      type: Boolean,
      default: false
    }
  },
  computed: {
    currentPage: {
      get() {
        return this.page
      },
      set(val) {
        this.$emit('update:page', val)
      }
    },
    pageSize: {
      get() {
        return this.limit
      },
      set(val) {
        this.$emit('update:limit', val)
      }
    }
  },
  methods: {
    handleSizeChange(val) {
      this.$emit('pagination', { page: this.currentPage, limit: val })
      if (this.autoScroll) {
        scrollTo(0, 800)
      }
    },
    handleCurrentChange(val) {
      this.$emit('pagination', { page: val, limit: this.pageSize })
      if (this.autoScroll) {
        scrollTo(0, 800)
      }
    }
  }
}
</script>

<style scoped>
.pagination-container {
  background: #fff;
  padding: 32px 16px;
}
.pagination-container.hidden {
  display: none;
}
</style>

2、使用

/**需要用到分页的页面*/
<template>
   <!-- 分页 -->
    <pagination
      v-show="total>0"
      :total="total"
      :offset.sync="listQuery.queryPage.pageNum"
      :limit.sync="listQuery.queryPage.pageSize"
      class="pagination-content"
      @pagination="getList"
    />
  </div>
</template>

<script>
import Pagination from '@/components/Pagination'
import { getAudit } from '@/api/app-audit.js'

export default {
  name: 'AppAudit',
  components: {
    Pagination
  },
  data() {
    return {
      auditList: [],
      total: 0, // 审计列表总数
      listQuery: { // 获取审计列表传参集合
        queryPage: {
          pageNum: 1, // 当前页
          pageSize: 10 // 每页显示条数
        }
      },
      loading: true
    }
  },
   created() {
    // 获取审计列表
    this.getList()
  },
  methods: {
    // 获取审计列表
    getList() {
      this.loading = true
      const params = {}
      params.appId = this.appId // 应用id
      params.pageNum = this.listQuery.queryPage.pageNum // 当前页
      params.pageSize = this.listQuery.queryPage.pageSize // 每页显示条数
      // 对分页进行相关操作的判断
      arguments[0] ? (params.pageSize = arguments[0].limit, params.pageNum = arguments[0].page) : params
      getAudit(params).then(res => {
        this.auditList = res.model
        this.total = res.totalCount
        this.loading = false
      }).catch(err => {
        this.loading = false
        err.errorMessage ? this.$message.info(err.errorMessage) : this.$message.info('获取审计列表出错啦，请稍后重试！')
      })
    }
  }
}
