vue element 分页页面初始请求两次的问题

主要是插件监听值的变化，初始化没彻底

//分页初始化

pageSize:"",

currentPage: 1,

 totalResult: '',

 pageNum: 1,

 

 

<div class="panel footer_list" v-cloak>

            <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" background :current-page="currentPage"

             :page-sizes="[50,100, 200, 300, 400]" :page-size="100" layout="total, sizes, prev, pager, next, jumper" :total="totalResult">

            </el-pagination>

        </div>
