vue如何实现Json格式数据展示
作者:A brick of socialism
这篇文章主要介绍了vue如何实现Json格式数据展示,具有很好的参考价值,希望对大家有所帮助。如有错误或未考虑完全的地方,望不吝赐教
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> </template> <!-- <span v-show="!innerclosed" class="body-line"></span>--> </div> <p v-if="!innerclosed && length" class="last-line"> <span>{{subfix}}</span> </p> </div> </div> </div> </template>

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脚本之家。
