vue-json-editor

1.安装vue-json-editor

npm install vue-json-editor --save

2.在.vue 文件中引用

import JsonEditor from "vue-json-editor";

3.使用

<template>
  <div class = "routeManagement">
    <vue-json-editor 
      v-model="routeJson" :showBtns="true" lang="zh"
      @json-change="onJsonChange" @json-save = "onJsonSave"/>
  </div>
</template>

<script>
// 引入vue-json-editor模块
import vueJsonEditor from 'vue-json-editor'
export default {
  data () {
    return{
      // 可使用 JSON.parse() JSON.stringify() 转化 json 数据
      json: {
        msg: 'demo of jsoneditor'
      }
    }
  },
  components: {
    vueJsonEditor
  },
  methods: {
    onJsonChange () { // 数据改变时触发
    },
    onJsonSave(){ // 点击保存触发
    }
  },
}
</script>

<style lang="scss" scoped>
.routeManagement{
  width:98%;
  margin:16px auto;
  /deep/.jsoneditor-vue{
    height:700px;
  }
  /deep/.json-save-btn{
    cursor: pointer;
  }
}
</style>

codemirror + json-lint

1.安装

npm install codemirror
npm install json-lint

2.组件

<template>
  <div class="json-editor">
    <textarea ref="textarea" />
  </div>
</template>

<script>
import CodeMirror from 'codemirror'
import 'codemirror/addon/lint/lint.css'
import 'codemirror/lib/codemirror.css'
import 'codemirror/theme/rubyblue.css'
require('script-loader!jsonlint')
import 'codemirror/mode/javascript/javascript'
import 'codemirror/addon/lint/lint'
import 'codemirror/addon/lint/json-lint'

export default {
  name: 'JsonEditor',
  /* eslint-disable vue/require-prop-types */
  props: ['value'],
  data() {
    return {
      jsonEditor: false
    }
  },
  watch: {
    value(value) {
      const editorValue = this.jsonEditor.getValue()
      if (value !== editorValue) {
        this.jsonEditor.setValue(JSON.stringify(this.value, null, 2))
      }
    }
  },
  mounted() {
    this.jsonEditor = CodeMirror.fromTextArea(this.$refs.textarea, {
      lineNumbers: true,
      mode: 'application/json',
      gutters: ['CodeMirror-lint-markers'],
      theme: 'rubyblue',
      lint: true
    })

    this.jsonEditor.setValue(JSON.stringify(this.value, null, 2))
    this.jsonEditor.on('change', cm => {
      this.$emit('changed', cm.getValue())
      this.$emit('input', cm.getValue())
    })
  },
  methods: {
    getValue() {
      return this.jsonEditor.getValue()
    }
  }
}
</script>

<style lang="scss" scoped>
.json-editor {
  height: 100%;
  position: relative;

  ::v-deep {
    .CodeMirror {
      height: auto;
      min-height: 300px;
    }

    .CodeMirror-scroll {
      min-height: 300px;
    }

    .cm-s-rubyblue span.cm-string {
      color: #F08047;
    }
  }
}
</style>

3.使用

先引入组件然后直接用
<JsonEditor ref="jsonEditor" v-model="jsonValue"></JsonEditor>
