vue使用element pagination组件

 <div v-if="pageshow">
       <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange"  :current-page="currentPage" :page-size="size" background layout="prev, pager, next" :total="total"></el-pagination>
 </div>

     handleSizeChange(val) {
        this.size = val
        this.getData(this.size, this.currentPage)
      },
      handleCurrentChange(val) {
        let page = val
        this.getData(this.size, page)
        this.pageshow = false
        this.$nextTick(() => {
          this.currentPage = val
          this.pageshow = true
        })
      }
