Backgroundimage在反应中不起作用

Question

我是新来的人，我想做出反应并尝试使用内联样式获取背景图片。但这不起作用。

显示错误“ URL未定义”

  render() {
    return (
        <div className="phase1" 
             style ={ { backgroundImage: url('https://lh3.googleusercontent.com/MOf9Kxxkj7GvyZlTZOnUzuYv0JAweEhlxJX6gslQvbvlhLK5_bSTK6duxY2xfbBsj43H=w300') } }>

            <input id="search" 
                   type="text" 
                   placeholder={this.state.search} 
                   onChange={this.updateSearch.bind(this)}/>
            &nbsp; &nbsp;&nbsp; &nbsp;

            <Link className="button1" to="Form"> + </Link>
        </div>
       )
    }
 }

CSS值始终是字符串。将backgroundImage值用引号引起来，使其成为字符串：

<div className="phase1" style ={ { backgroundImage: "url('https://lh3.googleusercontent.com/MOf9Kxxkj7GvyZlTZOnUzuYv0JAweEhlxJX6gslQvbvlhLK5_bSTK6duxY2xfbBsj43H=w300')" } }>
