Render HTML from a json string in react

Question

I'm trying to render an HTML object from a JSON string that I'm receiving from an API. I'm able to get the string to render to HTML successfully but it shows the entire JSON string. I'm only looking to get specific values (Phone, Name, Id.) What would be the best way for me to extract specific values from my JSON array and format it in HTML? I'm referring to records by state but I'm unable to get any sub-value of record in the render process.

class menuScreen extends React.Component {

    constructor(props) {
        super(props)

        const data = store.getState();

        this.state = {



            username: '',
            messages: data.messages
        }
    }

    handleSearch(e) {
        this.setState({username: e.target.value})
    }

    handleChange(evt) {
        this.setState({
            username: evt.target.value.substr(0, 100)
        });

    }

    onLinkClicked() {

        var conn = new jsforce.Connection({serverUrl: 'https://cs63.salesforce.com', accessToken: sessionStorage.getItem('token')})

        var parent = this.state.username
        //console.log(this.state.username)
        conn.sobject("Contact").find({
            LastName: {
                $like: parent
            }
        }, 'Id, Name, Phone'

        ).sort('-CreatedDate Name').
        limit(5).skip(10).execute(function(err, records) {
            if (err) {
                return console.error(err);
            }
            for (var i = 0; i < records.length; i++) {
                var record = (records[i]);
                console.log("Name: " + record.Name); //these are the records I'm trying to render
               console.log("Phone: " + record.Phone);


            } this.setState({records : records})


        }.bind(this));

    }

    render() {
        return (
            <div className='menubox' id='menubox'>
                <div className='searchbar-container'>
                    <form onSubmit={e => e.preventDefault()}>
                        <input type='text' size='25' placeholder='Contact Last Name' onChange={this.handleChange.bind(this)} value={this.state.username}/>
                        <button type='submit' onClick={this.onLinkClicked.bind(this)}>
                            Search
                        </button>
                    </form>
                   </div>
                <div>
            <div dangerouslySetInnerHTML={ { __html: JSON.stringify(this.state.records) } }></div> //how can I show specific values, isntead of the entire string?
        </div>
    </div>
        )
    }
}
export default menuScreen;

You can run a map function and output the JSX for each item.

class menuScreen extends React.Component {

    constructor(props) {
        super(props)

        const data = store.getState();

        this.state = {
            username: '',
            messages: data.messages,
            records: [],
        };
    }

    render() {
        return (
            <div>
                {this.state.records.map(record => (
                    <div>{record.attributes.name} {record.attributes.phone} {record.whatever}</div>
                )}
            </div>
        );
    }
}

Keep in mind, if you want a more complex HTML structure within map function, you'll have to wrap it in a single DOM node.

The full file would look like:

render() {
    return (
        <div className='menubox' id='menubox'>
            <div className='searchbar-container'>
                <form onSubmit={e => e.preventDefault()}>
                    <input type='text' size='25' placeholder='Contact Last Name' onChange={this.handleChange.bind(this)} value={this.state.username}/>
                    <button type='submit' onClick={this.onLinkClicked.bind(this)}>
                        Search
                    </button>
                </form>
            </div>
            <div>
                {this.state.records.map(record => (
                    <div>{record.attributes.name} {record.attributes.phone}</div>
                )}
            </div>
        </div>
    );
}
