JSON editor used by VUE2

1. Take a look at the effect picture first, and you can choose to display the effect by yourself

2. This is the JSON editor I use in the vue2 project, first introduce the third-party plug-in

npm install vue-json-editor --save

3. Introduce it into the project (the complete code will be placed at the bottom, and it can be used directly after installation)

// 导入模块
import vueJsonEditor from 'vue-json-editor'

// 注册组件
components: {
    
     vueJsonEditor },

4. Generally, what the backend returns is to convert JSON into a String form. We pass it to the backend through this form, and the data obtained by the backend can be converted between JSON and String.

// 后端拿到的数据
configValue："{\"isBigTree\":true,\"needContact\":true,\"needProvinceCity\":true,\"needDetailAddress\":true,\"needReservationCheckSms\":false,\"BigTreeReservationConfig\":{\"orderApiUrl\":\"https://api.bigtreedev.com/openplatform/openApi/api/order/create/notification/v001?sign=\",\"reservationApiUrl\":\"https://api.bigtreedev.com/openplatform/openApi/api/service/appointment/create/service/appointment/v001?sign=\",\"cancelApiUrl\":\"https://api.bigtreedev.com/openplatform/openApi/api/order/unsubscribe/notification/v001?sign=\",\"companyNo\":\"C400020\",\"verNo\":\"v001\",\"secretKey\":\"72CDFFD7F63D8662B6E1873FEA14EB24\",\"signSecretId\":\"0BBF774D11C0A053A6C2A2E36E6C6C2E2C55D483\"}}"
// 我们通过JSON.parse()进行转换
let isJson = JSON.parse(configValue) // 这样我们拿到的就是JSON格式的了，可以渲染出来的
// 我们传给后端的数据也要将JSON转成字符串，通过JSON.stringify()
let isString = JSON.stringify(configValue)  // 这样我们拿到的就是String格式的了，直接传给后端

5. The following is the complete code (with comments written)

<template>
  <div>
    <vue-json-editor
      v-model="resultInfo"
      :showBtns="false"
      :mode="'code'"
      @json-change="onJsonChange"
      @json-save="onJsonSave"
      @has-error="onError"
    />
    <br>
    <el-button type="primary" @click="checkJson">确定</el-button>
  </div>
</template>
