一、背景描述
现有一个vue项目,需要一个json编辑器,能够格式化json数据,同时也支持编辑功能。以下是列举了几种,可以根据风格或者喜好随意选择其中的一种即可。如果有兴趣的话,每一种都可以试着写下哦。
二、vue-json-edit
2.1 依赖安装
npm install vue-json-editor --save
2.2 示例代码
<template>
<div style="width:50% ">
<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>
<script>
// 导入模块
import vueJsonEditor from 'vue-json-editor'
export default {
// 注册组件
***ponents: { vueJsonEditor },
data () {
return {
hasJsonFlag: true, // json是否验证通过
// json数据
resultInfo: {
'employees': [
{
'firstName': 'Bill',
'lastName': 'Gates'
},
{
'firstName': 'George',
'lastName': 'Bush'
},
{
'firstName': 'Thomas',
'lastName': 'Carter'
}
]
}
}
},
mounted: function () {
},
methods: {
onJsonChange (value) {
// 实时保存
this.onJsonSave(value)
},
onJsonSave (value) {
this.resultInfo = value
this.hasJsonFlag = true
},
onError (value) {
this.hasJsonFlag = false
},
// 检查json
checkJson () {
if (this.hasJsonFlag === false) {
alert('json验证失败')
return false
} else {
alert('json验证成功')
return true
}
}
}
}
</script>

三、vue-json-pretty
3.1 依赖安装
以下是vue2版本的依赖,如果需要vue3请自行查询对应的版本然后安装对应的依赖
npm install vue-json-pretty@1.7.1 --save
3.2 示例代码
<template>
<div>
<vue-json-pretty :deep="3" selectableType="single" :showSelectController="true" :highlightMouseoverNode="true"
path="res" :data="response" > </vue-json-pretty>
</div>
</template>
<script>
import VueJsonPretty from 'vue-json-pretty'
import 'vue-json-pretty/lib/styles.css'
export default {
name: 'cluster',
***ponents: {VueJsonPretty},
data () {
return {
response: {
result: '',
data: [
{
id: 1,
title: 'aaa'
},
{
id: 2,
title: 'bbb'
},
{
id: 3,
title: '***c'
},
{
id: 4,
title: 'ddd'
}
]
}
}
}
}
</script>

四、bin-code-editor
官网:https://wangbin3162.gitee.io/bin-code-editor/#/jsonEditor
4.1 依赖安装
npm install bin-code-editor -d
4.2 示例代码
<template>

ref="editor"></CodeEditor>
<br>
<el-button type="primary"
@click="onSubumit">提交</el-button>
</div>
</template>
<script>
import { CodeEditor } from 'bin-code-editor'
console.log('CodeEditor', CodeEditor)
const jsonData = `{
"employees": [{
"firstName": "Bill",
"lastName": "Gates"
}, {
"firstName": "George",
"lastName": "Bush"
}, {
"firstName": "Thomas",
"lastName": "Carter"
}]
}`
export default {
// 注册组件
***ponents: { CodeEditor },
data () {
return {
jsonStr: jsonData
}
},
methods: {
// 检测json格式
isJSON (str) {
if (typeof str === 'string') {
try {
var obj = JSON.parse(str)
if (typeof obj === 'object' && obj) {
return true
} else {
return false
}
} catch (e) {
return false
}
} else if (typeof str === 'object' && str) {
return true
}
},
onSubumit () {
if (!this.isJSON(this.jsonStr)) {
this.$message.error(`json格式错误`)
return false
}
this.$message.su***ess('json格式正确')
}
}
}
</script>

五、vue-json-views
5.1 依赖安装
npm i -S vue-json-views
5.2 示例代码
<template>
<json-view :data="jsonData"/>
</template>
<script>
import jsonView from 'vue-json-views'
export default {
***ponents: {
jsonView
},
data () {
return {
// 可使用 JSON.parse() 对json数据转化
jsonData: {
name: 'dog',
age: 2,
hobby: {
eat: {
food: '狗粮',
water: '冰可乐'
},
sleep: {
time: '白日梦'
}

html,yaml, markdown, python编辑模式,默认为 json
6.1 依赖安装
下载时注意指定版本,且这里下载vue-codemirror,不是codemirror,两者现有版本不同,可在npm社区查看具体版本,默认下载是最新版本只支持Vue3。
这里下载的是vue-codemirror4.0.6 支持 Vue2:
npm install vue-codemirror@4.0.6
npm install jshint
npm install jsonlint
npm install script-loader

<template>
<div style="width:50%">
<codemirror ref="myCm"
v-model="editorValue"
:options="cmOptions"
@changes="onCmCodeChanges"
@blur="onCmBlur"
