Data display in Json format

The jsonViewer component of vue is also very easy to use. I feel good when I see a component written by God himself (recursive call) on the Internet. Make a little modification and record it.

JSON.stringify (obj, null, 4)

Can beautify the display of json data

The content to be highlighted is in the json data. If there is any content that needs to be highlighted, wrap it with the above tag (this needs to be done with the data, and the highlight style in the component can be modified as needed).

"{{jsonKey}}": {{prefix}} {{innerclosed? ('. '+ subfix):''}} {{isArray?'[]':'{}'}

{{(isArray?'':'"+ item.key +'":)}}

{{subfix}}

Export default {name: 'jsonView', props: {json: [Object, Array], jsonKey: {type: String, default:''}, closed: {type: Boolean, default: true} IsLast: {type: Boolean, default: true}, fontSize: {type: Number, default: 13}, expandDepth: {type: Number, default: 0} Depth: {type: Number, default: 0}}, created () {this.innerclosed =! this.closed? This.closed: this.depth > = this.expandDepth 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? This.json.length: Object.keys (this.json). Length}, subfix () {return (this.isArray?']':'}') + (this.isLast?':',)}, prefix () {return this.isArray?'[':'{'} Items () {if (this.isArray) {return this.json.map (item = > {const isJSON = this.isObjectOrArray (item) return {value: isJSON? Item: JSON.stringify (item), isJSON Key:''}})} const json = this.json return Object.keys (json) .map (key = > {const item = json [key] const isJSON = this.isObjectOrArray (item) return {value: isJSON? Item: JSON.stringify (item), isJSON, key} .bgView {background-color: # efefef; font-family: NotoSansCJKkr;} .json-view {position: relative; display: block Width: 100%; height: 100%; / * white-space: nowrap; * / padding: 020px; box-sizing: border-box; line-height: 30px;} .json-note {color: # 909399;} .json-key {color: # 333333;} .json-value {color: # 333333 } .json-item {margin: 0; padding-left: 20px;} .first-line {padding: 0; margin: 0;} .json-body {position: relative; padding: 0; margin: 0;} .json-body. Body-line {position: absolute; height: 100%; width: 0 Border-left: dashed 1px # bbb; top: 0; left: 2px;} .last-line {padding: 0; margin: 0;} .angle {position: absolute; display: block; cursor: pointer; float: left; width: 20px; text-align: center; left: 0 } .angle:: after {content: "; 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.angles:: after {border-left: solid 4px # 333 Border-top: solid 6px transparent; border-bottom: solid 6px transparent;} .light {color: # 0595ff;} vue parses json data

After the front end receives the json, it can be parsed using JSON.parse (jsonObject)! (jsonObject is a json object)
