vue3.0实现jsoneditor组件

踩了很多坑最后写出来了，需要props里加属性自己加，css部分也是很关键的内容
引用后可以在父组件用class设置height
很多处理的灵感来源于vue2.0项目vue-json-editor的代码，原项目代码还是写的很精彩的
安装命令：npm install jsoneditor --save

<template>
  <div>
    <div class="json" />
  </div>

<script>
import JSONEditor from 'jsoneditor';

export default {
  props: {
    name: String,
    modelValue: {
      type: [String, Number, Object, Array],
      default: () => {
        return {};
      }
    }
  },
  data() {
    return {
      jsonEditor: null,
      internalChange: false
    }
  },
  mounted() {
    this.init();
  },
  watch: {
    modelValue: {
      handler(json) {
        if (!this.internalChange) {
          this.setValue(json);
        }
      }
    }
  },
  methods: {
    init() {
      let self = this;
      this.jsonEditor = new JSONEditor(
          self.$el.querySelector(".json"), {
            mode: 'code',
            modes: ['code', 'view', 'tree'],
            indentation: 4,
            name: this.name,
            mainMenuBar: true,
            onModeChange() {
              // 去除作者信息
              if (document.getElementsByClassName('jsoneditor-poweredBy').item(0)) {
                document.getElementsByClassName('jsoneditor-poweredBy').item(0).remove();
              }
            },
            onChange() {
              self.internalChange = true;
              self.$emit('update:modelValue', self.jsonEditor.getText());
              // 防止双向绑定重复刷新数据
              self.$nextTick(function () {
                self.internalChange = false;
              });
            }
          }, self.modelValue);
      // 去除作者信息
      document.getElementsByClassName('jsoneditor-poweredBy').item(0).remove();
    },
    setValue(jsonStr) {
      if (this.jsonEditor) {
        this.jsonEditor.set(jsonStr ? JSON.parse(jsonStr) : '');
      }
    }
  }
};
</script>

<style>
@import '~jsoneditor/dist/jsoneditor.min.css';

.json {
  height: 100%;
}

.jsoneditor {
  border: thin solid #409EFF;
}

.jsoneditor-menu {
  background-color: #409EFF;
}

.ace-jsoneditor {
  min-height: 50px;
}
</style>

引入，省略import部分

<json-editor class="json" name="body" v-model="bodyJson"></json-editor>
