我是新手做出反应并尝试使用内联样式获取背景图像.但它不起作用.

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>
       )
    }
 }
