自定义箭头react-slick

Question

我正在使用react-slick在我的项目中创建一个旋转木马。我已经阅读了文档并尝试了不同的方法，但找不到一种方法来完全按照我需要的方式进行自定义……有没有人知道有没有办法让nextArrow显示在图片的前面而不是右边？查看下图以获得所需的结果：image

谢谢你的帮忙!

请参阅官方文档https://react-slick.neostack.com/docs/example/custom-arrows/ https://react-slick.neostack.com/docs/example/previous-next-methods代码：

import React, { Component } from "react";
import Slider from "react-slick";

function SampleNextArrow(props) {
  const { className, style, onClick } = props;
  return (
    <div
      className={className}
      style={{ ...style, display: "block", background: "red" }}
      onClick={onClick}
    />
  );
}

function SamplePrevArrow(props) {
  const { className, style, onClick } = props;
  return (
    <div
      className={className}
      style={{ ...style, display: "block", background: "green" }}
      onClick={onClick}
    />
  );
}

export default class CustomArrows extends Component {
  render() {
    const settings = {
      dots: true,
      infinite: true,
      slidesToShow: 3,
      slidesToScroll: 1,
      nextArrow: <SampleNextArrow />,
      prevArrow: <SamplePrevArrow />
    };
    return (
      <div>
        <h2>Custom Arrows</h2>
        <Slider {...settings}>
          <div>
            <h3>1</h3>
          </div>
          <div>
            <h3>2</h3>
          </div>
          <div>
            <h3>3</h3>
          </div>
          <div>
            <h3>4</h3>
          </div>
          <div>
            <h3>5</h3>
          </div>
          <div>
            <h3>6</h3>
          </div>
        </Slider>
      </div>
    );
  }
}

或

import React, { Component } from "react";
import Slider from "react-slick";

export default class PreviousNextMethods extends Component {
  constructor(props) {
    super(props);
    this.next = this.next.bind(this);
    this.previous = this.previous.bind(this);
  }
  next() {
    this.slider.slickNext();
  }
  previous() {
    this.slider.slickPrev();
  }
  render() {
    const settings = {
      dots: true,
      infinite: true,
      speed: 500,
      slidesToShow: 1,
      slidesToScroll: 1
    };
    return (
      <div>
        <h2>Previous and Next methods</h2>
        <Slider ref={c => (this.slider = c)} {...settings}>
          <div key={1}>
            <h3>1</h3>
          </div>
          <div key={2}>
            <h3>2</h3>
          </div>
          <div key={3}>
            <h3>3</h3>
          </div>
          <div key={4}>
            <h3>4</h3>
          </div>
          <div key={5}>
            <h3>5</h3>
          </div>
          <div key={6}>
            <h3>6</h3>
          </div>
        </Slider>
        <div style={{ textAlign: "center" }}>
          <button className="button" onClick={this.previous}>
            Previous
          </button>
          <button className="button" onClick={this.next}>
            Next
          </button>
        </div>
      </div>
    );
  }
}

我遇到了同样的问题，并一直试图通过遵循这个CustomArrows documentation和其他一些建议来寻找解决方案，但它们都没有像我想的那样工作(使用不同的箭头图标并在幻灯片顶部显示箭头)。然后我尝试遵循这个previousNextMethods documentation，并尝试从那里调整它。

index.js

    renderArrows = () => {
    return (
      <div className="slider-arrow">
        <ButtonBase
          className="arrow-btn prev"
          onClick={() => this.slider.slickPrev()}
        >
          <ArrowLeft />
        </ButtonBase>
        <ButtonBase
          className="arrow-btn next"
          onClick={() => this.slider.slickNext()}
        >
          <ArrowRight />
        </ButtonBase>
      </div>
    );
  };
  render() {
    return (
      <div className="App">
        <div style={{ position: "relative", marginTop: "2rem" }}>
          {this.renderArrows()}
          <Slider
            ref={c => (this.slider = c)}
            dots={true}
            arrows={false}
            centerMode={true}
            slidesToShow={2}
          >
            <div>
              <img src="http://placekitten.com/g/400/200" alt="cat" />
            </div>
            <div>
              <img src="http://placekitten.com/400/200" alt="cat" />
            </div>
            <div>
              <img src="http://placekitten.com/g/400/200" alt="cat" />
            </div>
            <div>
              <img src="http://placekitten.com/400/200" alt="cat" />
            </div>
          </Slider>
        </div>
      </div>
    );
  }

style.css

.App {
font-family: sans-serif;
}

.slider-arrow {
  position: absolute;
  z-index: 1;
  height: 100%;
  width: 100%;
}

.arrow-btn {
  top: 45%;
}
.next {
  float: right;
}

我希望这能有所帮助。codesandbox

我倾向于禁用箭头并自己构建它们。

创建引用

const slider = React.useRef(null);

附加到滑块

<Slider ref={slider} {...settings}>

在你想要的任何地方添加你的按钮

<button onClick={() => slider?.current?.slickPrev()}>Prev</button>
<button onClick={() => slider?.current?.slickNext()}>Next</button>
