前言

本文主要讲Outlet子路由渲染区域—>结构布局的封装。其中涉及的全局搜索hook函数，后面会单独拎出来讲，这期可先忽略，关注布局即可。

一、组件源码+解析如下

// @/layout/list/index.jsx
import React, { useRef, useImperativeHandle } from "react";
import { Pagination } from "antd";
import "./index.scss";
import useStore from "@/store";
import { useSearch } from "@/hook/index.js"; // hook
import { checkDataType } from "@/utils/common"; // utils
import Config from "@/config";

const CdList = (props) => {
  const { TableStore } = useStore();
  const { getReq } = useSearch();
  const state = useRef({
    pageIndex: getReq()?.pageIndex,
    pageSize: getReq()?.pageSize,
    total: 0,
    disabled: false,
  });
  const pageChange = (page, pageSize) => {
    const isFunction = checkDataType().isFunction(props?.page);
    if (!isFunction) {
      return false;
    }
    // 禁用按钮
    state.current.disabled = true;
    // 记录搜索动作类型
    TableStore.SET_FILTER_ACTION("page");
    // 记录页码
    TableStore.SET_PAGE({ size: pageSize, index: page });
    // 更新页码
    state.current.pageIndex = page;
    // 更新每页数量
    state.current.pageSize = pageSize;
    // 调用父组件更新表格数据方法
    props?.page(page, pageSize).finally(() => {
      state.current.disabled = false;
    });
  };
  // 设置总数
  const setTotal = (val) => {
    state.current.total = val * 1;
  };
  // 重置
  const reset = () => {
    state.current.pageIndex = Config.pageIndex;
  };
  // 暴露给父组件的方法放在这里
  useImperativeHandle(props?.tableRef, () => ({
    setTotal,
    reset,
  }));
  return (
    <div id="render-content">
      {/* 导航tab标签 */}
      <div id="render-content-header">
        {props.children.tabs ? (
          <>
            <div id="render-tabs">{props.children.tabs}</div>
          </>
        ) : null}
      </div>
      <div id="render-content-main">
        {/* 筛选 */}
        {props.children.tabschecked ? (
          <>
            <div id="render-tabs-checked">{props.children.tabschecked}</div>
          </>
        ) : null}
        {/* 搜索 */}
        {props.children.search ? (
          <>
            <div id="render-search">{props.children.search}</div>
          </>
        ) : null}
        {/* 手动控制 */}
        {props.children.control ? (
          <>
            <div id="render-control">{props.children.control}</div>
          </>
        ) : null}
        {/* 列表 */}
        <div id="render-body">
          <div>{props.children.default ? props.children.default : null}</div>
        </div>
        {/* 分页 */}
        <div id="render-footer">
          <Pagination className="pull-right" size="small" disabled={state.current.disabled} defaultCurrent={state.current.pageIndex} current={state.current.pageIndex} pageSize={state.current.pageSize} total={state.current.total} showSizeChanger onChange={pageChange} />
        </div>
      </div>
    </div>
  );
};

export default CdList;
-------------------------------------------------------------------------------------------------------------------
// @/layout/list/index.scss
#render-content {
  height: 100%;
  display: flex;
  flex-direction: column;
}
#render-content-header {
  background-color: #fff;
}
#render-content-main {
  flex: 1;
  height: 0;
  padding: 16px 24px 16px;
  background-color: #f0f2f5;
  box-sizing: border-box;
  display: flex;
  flex-direction: column;
}
#render-control {
  padding: 12px;
  background-color: #fff;
}
#render-body {
  flex: 1;
  height: 0;
  overflow-y: hidden;
  border-bottom: none;
  border-radius: 2px 2px 0 0;
  background-color: #fff;
  > div {
    padding: 0 12px;
    height: 100%;
  }
}
#render-footer {
  padding: 12px;
  border-radius: 0 0 2px 2px;
  background-color: #fff;
}
#render-tabs {
  padding: 0 24px;
  border-bottom: 1px solid #e9e9e9;
}
.block {
  height: 12px;
  background-color: #fff;
  border-radius: 2px 2px 0 0;
}
#render-tabs-checked {
  padding: 16px 16px 0;
  background-color: #fff;
  position: relative;
  &:after {
    content: "";
    position: absolute;
    border-bottom: 1px solid #e9e9e9;
    left: 16px;
    right: 16px;
    bottom: 0;
  }
}

二、页面使用方式

// 引用container组件
import CdList from "@/layout/list/index.jsx";
// html
<CdList tableRef={tableRef} page={changePage}>
  {{
     tabs: (
       <>
         {/* 导航tabs标签组件 */}
         {/* ... */}
       </>
     ),
     search: (
        <>
          {/* 筛选区域 */}
          {/* ... */}
        </>
     ),
     default: (
        <>
          {/* 表格区域 */}
          {/* ... */}
        </>
     ),
  }}
</CdList>
