组件使用

<pagination
      v-show="total > 0"
      :total="total"
      :page.sync="listQuery.page"
      :limit.sync="listQuery.limit"
      @pagination="getList"
    />
import Pagination from "@/components/Pagination"; // 分页组件
export default {
	components: { Pagination },
	data() {
        return {
            total: 0, // 数据总条数
            listQuery: {
                page: 1, // 当前页
                limit: 20, // 每页条数
            },
        };
    },
    methods: {
        getList(obj) {
            this.listQuery.page = obj.page;
            this.listQuery.limit = obj.limit;
            // 调用页面的查询方法
            this.testDataSearch();
        },
    }
}
