React-slick:如何同步3个滑块

Question

我正在使用react-slick滑块与3个滑块同步。有2个滑块，它工作得很好，但当我尝试3个滑块和2个参考时，它不工作。

constructor(props) {
    super(props);
    this.state = {
        nav1: null,
        nav2: null,
        nav3: null,
    };
}

componentDidMount() {
    this.setState({
        nav1: this.slider1,
        nav2: this.slider2,
        nav3: this.slider3,
    });
}

<Slider
       className="background-slider"
       asNavFor={this.state.nav2, this.state.nav3}
       ref={slider => (this.slider1 = slider)}
       {...settings1}> ...
</Slider>
<Slider
       className="content-slider"
       asNavFor={this.state.nav1, this.state.nav3}
       ref={slider => (this.slider2 = slider)}
       {...settings2}> ...
</Slider>
<Slider
       className="person-slider"
       asNavFor={this.state.nav2, this.state.nav1}
       ref={slider => (this.slider3 = slider)}
       {...settings3}> ...
</Slider>

谢谢

"asNavFor“属性需要单个值，而不是一列值，所以在其中放置多个ref将不起作用。

如果你让每个滑块指向下一个滑块，然后让最后一个点回到第一个滑块，这样做是可行的：

constructor(props) {
    super(props);
    this.state = {
        nav1: null,
        nav2: null,
        nav3: null,
    };
}

componentDidMount() {
    this.setState({
        nav1: this.slider1,
        nav2: this.slider2,
        nav3: this.slider3,
    });
}

<Slider
       className="background-slider"
       asNavFor={this.state.nav2}
       ref={slider => (this.slider1 = slider)}
       {...settings1}> ...
</Slider>
<Slider
       className="content-slider"
       asNavFor={this.state.nav3}
       ref={slider => (this.slider2 = slider)}
       {...settings2}> ...
</Slider>
<Slider
       className="person-slider"
       asNavFor={this.state.nav1}
       ref={slider => (this.slider3 = slider)}
       {...settings3}> ...
</Slider>

作为附注:我不知道这是官方支持的行为，还是仅仅是一个愉快的巧合，所以请谨慎使用。
