のためのコンテンツを文字列としてReactJSコンポーネントを使用する方法Google MapsのAPI情報ウィンドウ

Question

私はreactJS内部のGoogleマップのAPIを使用するアプリケーションを持っている：

https://github.com/strangebnb/react-airbnb

は私がするために必要なすべてを行うことに成功できましたReactJSコンポーネントをGoogle Maps APIのコンテンツ文字列として使用する点を除いてdo

2つのライブラリまたはnpmパッケージをマージするのに使用していません.2つのGoogle Maps APIとReactJSをマージします。ここ

マップをレンダリングするコンポーネント全体のための私のコードである：以下の方法で

、私contentStringはコンポーネント代わりHTMLまたは文字列を、反応する必要がありますGoogle APIが望むもの

createInfoWindow =() => { 
     let contentString = `<div>hi</div>` 
     return new google.maps.InfoWindow({ 
     map: this.map, 
     anchor: this.marker, 
     content: contentString 
     }) 
    } 

インフォボックスは、マップとマーカーとともにrenderMapメソッドでレンダリングされます。これの周りに仕事があるのですか、私は運が痛いですか？

Answer 1

あなたは例のコードは、それはかなり良いです

import ReactDOMServer from 'react-dom/server'; 


createInfoWindow =() => { 
    let contentString = ReactDOMServer.renderToString(<YourComponent/>); 
    return new google.maps.InfoWindow({ 
    map: this.map, 
    anchor: this.marker, 
    content: contentString 
    }) 
}
