怎么新建MySQL数据库

这篇文章给大家分享的是“Vue3进行列表界面数据展示的方法及操作是什么”，对大家学习和理解有一定的参考价值和帮助，有这方面学习需要的朋友，接下来就跟随小编一起学习一下吧。

一、列表界面展示示例

现在要做的就是把打到页面的数据，带样式，也就是说好看点显示。

之前我们在《Vue3（二）集成Ant Design Vue》这篇文章中，有提及组件的使用，对于一个前端不是很好（后端也不咋的），本着拿来主义，我们能现成的是最好、最省事的方式了。

直白点说就是，找Ant Design Vue现成的组件，将列表数据按组件样式显示到界面上。

1、挑选自己喜欢的列表样式

从https://2x.antdv.com/components/list-cn中，找到list列表，找到自己喜欢的风格，

如下图所示：

2、进行数据显示

2.1、组件在列表显示

接下来，我们只需要在home里进行修改即可，找到刚才对应组件的位置，把对应代码拷贝到home中，然后在进行修改即可，

示例代码如下：

<template>
  <a-layout>
    <a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"
          v-model:selectedKeys="selectedKeys2"
          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
          </template>
          <a-menu-item key="1">option1</a-menu-item>
          <a-menu-item key="2">option2</a-menu-item>
          <a-menu-item key="3">option3</a-menu-item>
          <a-menu-item key="4">option4</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub2">
          <template #title>
                <span>
                  <laptop-outlined />
                  subnav 2
                </span>
          </template>
          <a-menu-item key="5">option5</a-menu-item>
          <a-menu-item key="6">option6</a-menu-item>
          <a-menu-item key="7">option7</a-menu-item>
          <a-menu-item key="8">option8</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub3">
          <template #title>
                <span>
                  <notification-outlined />
                  subnav 3
                </span>
          </template>
          <a-menu-item key="9">option9</a-menu-item>
          <a-menu-item key="10">option10</a-menu-item>
          <a-menu-item key="11">option11</a-menu-item>
          <a-menu-item key="12">option12</a-menu-item>
        </a-sub-menu>
      </a-menu>
    </a-layout-sider>
    <a-list item-layout="vertical" size="large" :pagination="pagination" :data-source="listData">
      <template #footer>
        <div>
          <b>ant design vue</b>
          footer part
        </div>
      </template>
      <template #renderItem="{ item }">
        <a-list-item key="item.title">
          <template #actions>
          <span v-for="{ type, text } in actions" :key="type">
            <component v-bind:is="type" style="margin-right: 8px" />
            {{ text }}
          </span>
          </template>
          <template #extra>
            <img
                width="272"
                alt="logo"
                src="https://gw.alipayobjects.com/zos/rmsportal/mqaQswcyDLcXyDKnZfES.png"
            />
          </template>
          <a-list-item-meta :description="item.description">
            <template #title>
              <a :href="item.href" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >{{ item.title }}</a>
            </template>
            <template #avatar><a-avatar :src="item.avatar" /></template>
          </a-list-item-meta>
          {{ item.content }}
        </a-list-item>
      </template>
    </a-list>
  </a-layout>
</template>

<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];

for (let i = 0; i < 23; i++) {
  listData.push({
    href: 'https://www.antdv.com/',
    title: `ant design vue part ${i}`,
    avatar: 'https://zos.alipayobjects.com/rmsportal/ODTLcjxAfvqbxHnVXCYX.png',
    description:
        'Ant Design, a design language for background applications, is refined by Ant UED Team.',
    content:
        'We supply a series of design principles, practical patterns and high quality design resources (Sketch and Axure), to help people create their product prototypes beautifully and efficiently.',
  });
}

export default defineComponent({
  components: {
    StarOutlined,
    LikeOutlined,
    MessageOutlined,
  },
  name: 'Home',
  setup(){
    const pagination = {
      onChange: (page: number) => {
        console.log(page);
      },
      pageSize: 3,
    };
    const actions: Record<string, string>[] = [
      { type: 'StarOutlined', text: '156' },
      { type: 'LikeOutlined', text: '156' },
      { type: 'MessageOutlined', text: '2' },
    ];
    console.log('set up');
    //使用ref进行数据绑定
    const ebooks=ref();
    // 使用reactive进行数据绑定
    const ebooks1=reactive({books:[]})
    onMounted(()=>{
      axios.get("http://localhost:8888/ebook/list?name=spring").then(response =>{
        console.log("onMounted");
        const data=response.data;
        ebooks.value=data.content;
        ebooks1.books=data.content;
      })
    })
    return{
      listData,
      pagination,
      actions,
      ebooks1: ebooks,
      ebooks2:toRef(ebooks1,"books")
    }

  }
});
</script>

重新编译运行，查看效果如下：

2.2、接口返回数据在列表显示

明显现在，可以看到想要用的列表样式已经在页面中成功展示了，但这并不是我想要的，我想要的是后端接口返回数据在此处展示，也就是数据源，接下来,我们再次调整Home的代码，

示例代码如下：

<template>
  <a-layout>
    `<a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"
          v-model:selectedKeys="selectedKeys2"
          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
          </template>
          <a-menu-item key="1">option1</a-menu-item>
          <a-menu-item key="2">option2</a-menu-item>
          <a-menu-item key="3">option3</a-menu-item>
          <a-menu-item key="4">option4</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub2">
          <template #title>
                <span>
                  <laptop-outlined />
                  subnav 2
                </span>
          </template>
          <a-menu-item key="5">option5</a-menu-item>
          <a-menu-item key="6">option6</a-menu-item>
          <a-menu-item key="7">option7</a-menu-item>
          <a-menu-item key="8">option8</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub3">
          <template #title>
                <span>
                  <notification-outlined />
                  subnav 3
                </span>
          </template>
          <a-menu-item key="9">option9</a-menu-item>
          <a-menu-item key="10">option10</a-menu-item>
          <a-menu-item key="11">option11</a-menu-item>
          <a-menu-item key="12">option12</a-menu-item>
        </a-sub-menu>
      </a-menu>
    </a-layout-sider>`
    <a-list item-layout="vertical" size="large" :pagination="pagination" :data-source="ebooks1">
      <template #renderItem="{ item }">
        <a-list-item key="item.name">
          <template #actions>
          <span v-for="{ type, text } in actions" :key="type">
            <component v-bind:is="type" style="margin-right: 8px" />
            {{ text }}
          </span>
          </template>
          <a-list-item-meta :description="item.description">
            <template #title>
              <a :href="item.href" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >{{ item.name }}</a>
            </template>
            <template #avatar><a-avatar :src="item.cover" /></template>
          </a-list-item-meta>
        </a-list-item>
      </template>
    </a-list>
  </a-layout>
</template>

<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];

for (let i = 0; i < 23; i++) {
  listData.push({

        ebooks.value=data.content;
        ebooks1.books=data.content;
      })
    })
    return{
      listData,
      pagination,
      actions,
      ebooks1: ebooks,
      ebooks2:toRef(ebooks1,"books")
    }

  }
});
</script>
<style>
.ant-layout-sider{
  float: left;
}
</style>

重新编译运行，查看效果如下：

2.3、接口数据改造

很明显，列表数据太少，我对接口进行改造，让其返回多条数据。

我们从service中，不难看出我们做的是，不管传入什么，都是写死的走的模糊查询，这里我们改成动态SQL即可，

示例代码如下：

package com.rongrong.wiki.service;

import com.rongrong.wiki.domain.EBook;
import com.rongrong.wiki.domain.EBookExample;
import com.rongrong.wiki.mapper.EBookMapper;
import com.rongrong.wiki.req.EBookReq;
import com.rongrong.wiki.resp.EBookResp;
import org.springframework.stereotype.Service;
import org.springframework.util.ObjectUtils;

import javax.annotation.Resource;
import java.util.List;

import static com.rongrong.wiki.util.CopyUtil.copyList;

/**
 * @author rongrong
 * @version 1.0
 * @description
 * @date 2021/10/13 23:09
 */
@Service
public class EBookService {

    @Resource
    private EBookMapper eBookMapper;

    public List<EBookResp> list(EBookReq eBookReq) {
        EBookExample eBookExample = new EBookExample();
        //此处代码的意思相当于，搞了一个Sql的where条件
        EBookExample.Criteria criteria = eBookExample.createCriteria();
        //划波浪线为不推荐使用，这里我们去看源代码做个替换即可
        if(!ObjectUtils.isEmpty(eBookReq.getName())){
            criteria.andNameLike("%"+eBookReq.getName()+"%");
        }
        List<EBook> eBookList = eBookMapper.selectByExample(eBookExample);
        //List<EBookResp> eBookRespList = new ArrayList<>();
        //for (EBook eBook: eBookList) {
        //    //EBookResp eBookResp = new EBookResp();
        //    ////spring boot 自带的BeanUtils完成对象的拷贝
        //    //BeanUtils.copyProperties(eBook, eBookResp);
        //    //eBookResp.setId(12345L);
        //    //单体复制
        //    EBookResp copy = copy(eBook, EBookResp.class);
        //    eBookRespList.add(copy);
        //}
        //列表复制
        List<EBookResp> respList = copyList(eBookList, EBookResp.class);
        return respList;
    }
}

查看接口返回数据，如下：

2.4、list列表一行显示为多条数据

接口改造完成，接着需要对列表显示内容进行修改，同样在list列表找到栅格列表，我们还在home中修改，示例代码如下：

<template>
  <a-layout>
    `<a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"
          v-model:selectedKeys="selectedKeys2"
          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
          </template>
          <a-menu-item key="1">option1</a-menu-item>
          <a-menu-item key="2">option2</a-menu-item>
          <a-menu-item key="3">option3</a-menu-item>
          <a-menu-item key="4">option4</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub2">
          <template #title>
                <span>
                  <laptop-outlined />
                  subnav 2
                </span>
          </template>
          <a-menu-item key="5">option5</a-menu-item>
          <a-menu-item key="6">option6</a-menu-item>
          <a-menu-item key="7">option7</a-menu-item>
          <a-menu-item key="8">option8</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub3">
          <template #title>
                <span>
                  <notification-outlined />
                  subnav 3
                </span>
          </template>
          <a-menu-item key="9">option9</a-menu-item>
          <a-menu-item key="10">option10</a-menu-item>
          <a-menu-item key="11">option11</a-menu-item>
          <a-menu-item key="12">option12</a-menu-item>
        </a-sub-menu>
      </a-menu>
    </a-layout-sider>`
    <a-list item-layout="vertical" size="large"
            :grid="{ gutter: 16, column: 3 }" :data-source="ebooks1">
      <template #renderItem="{ item }">
        <a-list-item key="item.name">
          <template #actions>
          <span v-for="{ type, text } in actions" :key="type">
            <component v-bind:is="type" style="margin-right: 8px" />
            {{ text }}
          </span>
          </template>
          <a-list-item-meta :description="item.description">
            <template #title>
              <a :href="item.href" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >{{ item.name }}</a>
            </template>
            <template #avatar><a-avatar :src="item.cover" /></template>
          </a-list-item-meta>
        </a-list-item>
      </template>
    </a-list>
  </a-layout>
</template>

<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];

export default defineComponent({
  components: {
    StarOutlined,
    LikeOutlined,
    MessageOutlined,
  },
  name: 'Home',
  setup(){
    const pagination = {
      onChange: (page: number) => {
        console.log(page);
      },
      pageSize: 3,
    };
    const actions: Record<string, string>[] = [
      { type: 'StarOutlined', text: '156' },
      { type: 'LikeOutlined', text: '156' },
      { type: 'MessageOutlined', text: '2' },
    ];
    console.log('set up');
    //使用ref进行数据绑定
    const ebooks=ref();
    // 使用reactive进行数据绑定
    const ebooks1=reactive({books:[]})
    onMounted(()=>{
      axios.get("http://localhost:8888/ebook/list?name=").then(response =>{
        console.log("onMounted");
        const data=response.data;
        ebooks.value=data.content;
        ebooks1.books=data.content;
      })
    })
    return{
      pagination,
      actions,
      ebooks1: ebooks,
      ebooks2:toRef(ebooks1,"books")
    }

  }
});
</script>
<style>
.ant-layout-sider{
  float: left;
}
</style>

知识点：

• :grid="{ gutter: 16, column: 4 }" ，是进行栅格显示，栅格间隔16，每行显示4个
• 这里要删除:pagination="pagination"  ，即分页显示
  

再来重新编译，查看效果如下：

2.5、列表内容前图标样式修改

一切看是很好，但感觉是图书封面有点小不好看，如下图：

来接着改样式，只需在home里调整即可，示例代码如下：

html
<template>
  <a-layout>
    `<a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"
          v-model:selectedKeys="selectedKeys2"
          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
          </template>
