Vue3 list interface data display details

Vue3 list interface data display details

1. List interface display example

What we need to do now is to style the data entered into the page, that is, to make it look better.

Previously, in the article "Vue3 (Part 2) Integrating Ant Design Vue", we mentioned the use of components. For a front-end that is not very good (the back-end is not very good either), in the spirit of "take what you need", the best and most convenient way is to use what we have ready-made.

To put it simply, find ready-made components of Ant Design Vue and display the list data on the interface according to the component style.

1. Choose your favorite list style

From https://2x.antdv.com/components/list-cn , find the list and find the style you like.

As shown in the following figure:

2. Display data

2.1. Components are displayed in the list

Next, we only need to make changes in home , find the location of the corresponding component just now, copy the corresponding code to home , and then make changes.

The sample code is as follows:

<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>

2.2. The data returned by the interface is displayed in a list

Obviously now, you can see that the list style you want to use has been successfully displayed on the page, but this is not what I want. What I want is that the data returned by the backend interface is displayed here, that is, the data source. Next, let's adjust the Home code again.

2.3 Interface data transformation

Obviously, the list data is too small, so I modified the interface to return multiple data.

From service , it is not difficult to see that what we do is that no matter what is passed in, it is a hard-coded fuzzy query. Here we can change it to dynamic SQL .

The sample code is as follows:

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();
        //The meaning of the code here is equivalent to creating a Sql where condition EBookExample.Criteria criteria = eBookExample.createCriteria();
        //The wavy line indicates that it is not recommended. Let's look at the source code and make a replacement 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's own BeanUtils completes the object copy// //BeanUtils.copyProperties(eBook, eBookResp);
        // //eBookResp.setId(12345L);
        // //Single copy// EBookResp copy = copy(eBook, EBookResp.class);
        // eBookRespList.add(copy);
        //}
        //List copy List<EBookResp> respList = copyList(eBookList, EBookResp.class);
        return respList;
    }
}

View the data returned by the interface, as follows:

2.4. List displays multiple data in one row

The interface modification is completed. Then we need to modify the list display content. Similarly, we find the grid list in the list list. We also modify it in home . The sample code is as follows:

<template>
  <a-layout>
    `<a-layout-sider width="200" style="background: #fff">

    return {
      pagination,
      actions,
      ebooks1: ebooks,
      ebooks2:toRef(ebooks1,"books")
    }

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

Knowledge points:

  • :grid="{ gutter: 16, column: 4 }" is for grid display, with a grid interval of 16 and 4 items per row
  • Here we need to delete: pagination="pagination" , that is, pagination display

Recompile again and see the effect as follows:

2.5. Change the icon style before the list content

Everything looks good, but the book cover is a little small and ugly, as shown below:

To change the style, just adjust it in home. The sample code is as follows:

html
<template>
  <a-layout>
    `<a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"

          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />

                </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>
