 <div class="pagePagination">
        <el-pagination
          @current-change="handleCurrentChange"
          :page-size="listPageEvery"
          layout="prev, pager, next"
          prev-text="<上一页"
          next-text="下一页>"
          :total="listAllNum"
          background
          :current-page.sync="listCurrentPage"
          v-if="listAllNum != 0"
        ></el-pagination>
 </div>

js分页

// 页码跳跃
    handleCurrentChange(currentPage) {
      this.getList(currentPage);
      this.listCurrentPage = currentPage;
      this.setContextData("listCurrentPage", this.listCurrentPage);
    },

   //给sessionStorage存值
    setContextData: function (key, value) {
      if (typeof value == "string") {
        sessionStorage.setItem(key, value);
      } else {
        sessionStorage.setItem(key, JSON.stringify(value));
      }
    },
    // 从sessionStorage取值
    getContextData: function (key) {
      const str = sessionStorage.getItem(key);
      if (typeof str == "string") {
        try {
          return JSON.parse(str);
        } catch (e) {
          return str;
        }
      }
      return;
    },
