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' : '']" :style="'font-size:' + fontSize+'px'">
<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" style="cursor: pointer;">
{{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">
<template v-for="(item, index) in items">
<json-view v-if="item.isJSON"
:closed="closed"
:key="index"
:json="item.value"
:jsonKey="item.key"
:depth="depth+1"
:expandDepth="expandDepth"
:isLast="index === items.length - 1"></json-view>
<p v-else class="json-item" :key="index">
<span class="json-key">
{{(isArray ? '' : '"' + item.key + '":')}}
</span>
<span class="json-value" v-html="item.value + (index === items.length - 1 ? '' : ',')"/>
</p>

</style>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阿兔在线工具。
