elementUI的坑

(1)el-pagination

会出现页面显示不出来，total必须是number类型

 <el-pagination
      v-if="total>0"
      @size-change="handlePageSize"
      @current-change="handlePage"
      :current-page.sync="page.pageNum"
      :page-size="page.pageSize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="total">
</el-pagination>
