vue如何实现Json格式数据展⽰

Json格式数据展⽰
vue的jsonViewer组件也很好⽤，在⽹上看到有⼤神⾃⼰写的组件（递归调⽤），觉得很好，稍作修改，记录⼀下
JSON.stringify(obj, null, 4)
可以美化json数据的显⽰
<span class="light">要⾼亮的内容</span> 在json数据中，如果有需要⾼亮的内容，⽤以上标签包起来（这个要处理数据实现了，组件⾥⾼亮样式可以根据需要⾃⼰修改）
<template>
<div class="bgView">
<div :class="['json-view', length ? 'closeable' : '']" :>
<span @click="toggleClose" :class="['angle', innerclosed ? 'closed' : '']" v-if="length"></span>
<div class="content-wrap">
<p class="first-line">
<span v-if="jsonKey" class="json-key">"{{jsonKey}}": </span>
<span v-if="length" @click="toggleClose" >
{{prefix}}
{{innerclosed ? ('... ' + subfix) : ''}}
<!-- <span class="json-note">
{{innerclosed ? (' // count: ' + length) : ''}}
</span> -->
</span>
<span v-if="!length">{{isArray ? '[]' : '{}'}}</span>
</p>
<div v-if="!innerclosed && length" class="json-body">

vue解析json数据
在前端接授到json后，使⽤JSON.parse(jsonObject)就可以解析！（jsonObject为json对象）以上为个⼈经验，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
