Vue中使用JsonView来展示Json树的实例代码
(编辑：jimmy 日期: 2024/11/10 浏览：2)
前两天干活儿有个需求，在前端需要展示可折叠的Json树，供开发人员查看，这里采用JsonView组件来实现，它是一款用于展示Json的Vue组件，支持大体积的Json文件快速解析渲染，下面记录一下实现过程。
1.首先先下载好JsonView的组件：JsonView.vue，组件代码如下：
<template>
<div class="bgView">
<div :class="['json-view', length " :style="'font-size:' + fontSize+'px'">
<span @click="toggleClose" :class="['angle', innerclosed " 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">
{{prefix}}
{{innerclosed "json-note">
{{innerclosed "!length">{{isArray "!innerclosed && length" class="json-body">
<template v-for="(item, index) in items">
<json-view :closed="closed" v-if="item.isJSON" :key="index" :json="item.value"
:jsonKey="item.key" :isLast="index === items.length - 1"></json-view>
<p class="json-item" v-else :key="index">
<span class="json-key">
{{(isArray "' + item.key + '"')}}
</span>
:
<span class="json-value">
{{item.value + (index === items.length - 1 "!innerclosed" class="body-line"></span>
</div>
<p v-if="!innerclosed && length" class="last-line">
<span>{{subfix}}</span>
</p>
</div>
</div>
</div>
</template>
<script>
export default {
name: 'jsonView',
props: {
json: [Object, Array],
jsonKey: {
type: String,
default: ''
},
closed: {
type: Boolean,
default: false
},
isLast: {
type: Boolean,
default: true
},
fontSize: {
type: Number,
default: 13
}
},
created() {
this.innerclosed = this.closed
this.$watch('closed', () => {
this.innerclosed = this.closed
})
},
data() {
return {
innerclosed: true
}
},
methods: {
isObjectOrArray(source) {
const type = Object.prototype.toString.call(source)
const res = type === '[object Array]' || type === '[object Object]'
return res
},
toggleClose() {
if (this.innerclosed) {
this.innerclosed = false
} else {
this.innerclosed = true
}
}
},
computed: {
isArray() {
return Object.prototype.toString.call(this.json) === '[object Array]'
},
length() {
return this.isArray "";
display: inline-block;
width: 0;
height: 0;
vertical-align: middle;
border-top: solid 4px #333;
border-left: solid 6px transparent;
border-right: solid 6px transparent;
}
.angle.closed::after {
border-left: solid 4px #333;
border-top: solid 6px transparent;
border-bottom: solid 6px transparent;
}
</style>
2.在需要使用的vue页面中引用JsonView组件
import JsonView from '@/components/JsonView'
3.定义Json数据变量
jsonData:{},
4.页面展示代码
<JsonView :json="jsonData"></JsonView>
5.实现效果如下：
JsonViewAttributes
