自定义箭头反应光滑

问题描述 投票：0回答：13

我正在使用react-slick 在我的项目中创建一个轮播。 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自定义它...有谁知道是否有办法让 nextArrow 显示在图像前面/前面而不是显示在图像上这是正确的？ 请参阅下图以获得所需的结果： image

感谢您的帮助！

我倾向于禁用箭头并自己构建它们。

创建参考

const slider = React.useRef(null);

连接到滑块

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

在任意位置添加按钮

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

我遇到了同样的问题，并一直尝试按照此CustomArrows文档和其他一些建议来搜索解决方案，但它们都没有达到我想要的效果（对箭头使用不同的图标并在顶部显示箭头）幻灯片）。然后我尝试遵循这个previousNextMethods文档，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>
    );
  }

样式.css

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

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

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

我希望这会有所帮助。 代码沙盒

查看官方文档 https://react-slick.neostack.com/docs/example/custom-arrows/ https://react-slick.neostack.com/docs/example/previous-next-methods 那里的代码：

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>

      dots: true,
      infinite: true,
      speed: 500,
      slidesToShow: 1,
      slidesToScroll: 1

你可以试试这个方法

render() {
    const ArrowLeft = (props) => (
        <button
            {...props}
            className={'prev'}/>
    );
    const ArrowRight = (props) => (
        <button
            {...props}
            className={'next'}/>
    );

    const settings = {
        arrows: true,
        prevArrow: <ArrowLeft />,
        nextArrow: <ArrowRight />,
    };

    return (
        <Slider {...settings}>
            {/* items... */}
        </Slider>
    )
}

如果有人尝试达到相同的结果，可以使用一些 css 来实现：

.slick-next {
  right: 25px; 
}

添加自定义CSS样式

.slick-next {
  background: url('./images/next.png') center center no-repeat!important;

  &::before {
    display: none;
  }
}

.slick-prev {
  background: url('./images/back.png') center center no-repeat!important;

  &::before {
    display: none;
  }
}

您可以构建自己的箭头，就像上面每个人指出的那样，在他们的文档中提到了这一点。

但是如果你想更改图像（大多数情况都是这样），那么我所做的只是为滑块添加 2 行代码

.slick-next:before & .slick-prev:before
并用图像替换内容。有了这个，您不需要处理禁用最后一项上的箭头（这是默认的）。使用下面的代码只会更改您的箭头，其余行为保持不变。

请看下面的代码

.some_class .slick-slider {
    button.slick-next:before {
        content: url("your_image_here.svg");
    }
    button.slick-prev:before {
        content: url("your_image_here.svg");
    }
   }

请记住，需要将 onClick 属性添加到您的按钮中：

const SlickArrow = ({onClick}: props) => (
  <button onClick={onClick}><Icon.Arrow /></button>
);

此示例用另一个图标替换默认箭头

import Slider from "react-slick";
import './Example2.css'
import "slick-carousel/slick/slick.css"; 
import "slick-carousel/slick/slick-theme.css";
import { FaBeer } from 'react-icons/fa'

function SampleNextArrow(props: any) {
  const { className, style, onClick } = props;
  return (
    <div
      className={className}
      onClick={onClick}
    ><FaBeer style={{ ...style, color: "red", fontSize: "30px" }} /></div>
  );
}

function SamplePrevArrow(props: any) {
  const { className, style, onClick } = props;
  return (
    <div
      className={className}
      onClick={onClick}
    ><FaBeer style={{ ...style, color: "red", fontSize: "30px" }} /></div>
  );
}

const Example2 = () => {
  const settings = {
    dots: true,
    infinite: true,
    speed: 500,
    slidesToShow: 1,
    slidesToScroll: 1,
    nextArrow: <SampleNextArrow />,
    prevArrow: <SamplePrevArrow />
  };

  return (
    <div className="wrapper">
      <h1>example 2</h1>
      <Slider {...settings}>
          <div>
            <h3>1</h3>
          </div>
          <div>
            <h3>2</h3>
          </div>
          <div>
            <h3>3</h3>
          </div>
          <div>
            <h3>4</h3>

很多人用不同的方法回答这个问题。我也想出了我的。这是我的方法，仅使用一个组件，我们将生成两侧的下一个和上一个箭头，并为它们提供适当的样式。

LiveScoreArrowsComponent.jsx

import React from 'react'
import PropTypes from 'prop-types'

LiveScoreSliderArrow.propTypes = {
  className : PropTypes.string,
  onClick : PropTypes.func,
  style : PropTypes.object,
}
function LiveScoreSliderArrow(props) {
  const {className, style, onClick} = props;
  let arrow_direction = className.search("slick-prev") != -1 ? "left" : "right";
  let class_by_direction = {
    left: className.replace("slick-prev", ""),
    right: className.replace("slick-next", "")
  }

  let hide_flag_class = className.search("slick-disabled") != -1 ? " d-none" : "" 
  return (
    <button style={{...style, top: "unset", lineHeight: "normal"}} className={class_by_direction[arrow_direction] + hide_flag_class + ` p-1 shadow border text-black rounded ri-arrow-${arrow_direction}-s-line ${arrow_direction}`} onClick={onClick}></button>
  )
}

export default LiveScoreSliderArrow

SlickSlider设置

const SETTINGS = {
  slidesToShow: 3,
  infinite: false,
  swipeToSlide: true,
  slidesToScroll: 3,
  variableWidth: true,
  arrows: true,
  nextArrow: <LiveScoreSliderArrow />,
  prevArrow: <LiveScoreSliderArrow />,
}

首先确保将react-slick Slider 包装到其他自定义滑块组件中

import React from 'react'
import Slider from 'react-slick'
import PropTypes from 'prop-types'

import Card from '../livescore/card'

LiveScoreSlider.propTypes = {
    data: PropTypes.array.isRequired,
    settings: PropTypes.object.isRequired
}
function LiveScoreSlider({data, settings}) {
  return (
    <Slider className="col-sm-12 d-flex align-items-center livescore-scorecard-container" {...settings}>
        {
                  data.map((livescore, index)=>{
                    // console.log(livescore)
                    return <Card
                      key={index}
                      team1={livescore.teams[0]}
                      team2={livescore.teams[1]}
                      match={livescore.match}
                      stadium={livescore.stadium}
                      series={livescore.series}
                    />
                  })
         }
    </Slider>
  )
}

export default LiveScoreSlider

我从上面 Oleg 的答案开始，并对其进行了一些更改以使用 FontAwesome 图标。此方法可以很好地防止额外的属性被发送到 FontAwesome 组件，从而导致错误，例如“React 无法识别 DOM 元素上的 

currentSlide
属性”。感谢奥列格提供的图案。

import React from 'react';
import Slider from 'react-slick';
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';

const SomeComponent: React.FC = (): JSX.Element => {

  const NextArrow = (props: any) => {
    const { className, style, onClick } = props;
    return (
      <div
        className={className}
        style={{ ...style, display: 'block' }}
        onClick={onClick}
      >
        <FontAwesomeIcon icon="fa-solid fa-chevron-right" />
      </div>
    );
  };

  const PrevArrow = (props: any) => {
    const { className, style, onClick } = props;
    return (
      <div
        className={className}
        style={{ ...style, display: 'block' }}
        onClick={onClick}
      >
        <FontAwesomeIcon icon="fa-solid fa-chevron-left" />
      </div>
    );
  };

  const settings = {
    // other settings here ...
    nextArrow: <NextArrow />,
    prevArrow: <PrevArrow />,
    // more settings here ...
  };

  return (
    <Slider {...settings}>
      {/* inner stuff here */}
    </Slider>
  );
};
