在反应中一次导入多个图像文件的任何简单方法

我输入以下内容来导入图像。需要一个简短的方法来做到这一点。

import banner1 from "./imgs/Banners/banner1.jpg"
import banner2 from "./imgs/Banners/banner2.jpg"
import banner3 from "./imgs/Banners/banner3.jpg"
import banner4 from "./imgs/Banners/banner4.jpg"
import banner5 from "./imgs/Banners/banner5.jpg"
import banner6 from "./imgs/Banners/banner6.jpg"
import banner7 from "./imgs/Banners/banner7.jpg"
import banner8 from "./imgs/Banners/banner8.jpg"
import banner9 from "./imgs/Banners/banner9.jpg"
.
.
.
import banner(n) from "./imgs/Banners/banner(n).jpg"

• 既然你使用的是 webpack，请看一下需要上下文 https://webpack.js.org/guides/dependency-management/#require-context。您应该能够导入所有 png 文件'./imgs/Banners' to images多变的。然后你可以使用图像images["banner(n).png"].

function importAll(r) {
    let images = {};
    r.keys().map((item, index) => { images[item.replace('./', '')] = r(item); });
    return images;
}

const images = importAll(require.context('./imgs/Banners', false, '/\.jpg/'));

<img src={images["banner1.png"]} />

• 另一种方式，您可以使用专用于这些导入的文件：

images.js :

import banner1 from "./imgs/Banners/banner1.jpg"
import banner2 from "./imgs/Banners/banner2.jpg"
import banner3 from "./imgs/Banners/banner3.jpg"
import banner4 from "./imgs/Banners/banner4.jpg"
import banner5 from "./imgs/Banners/banner5.jpg"
import banner6 from "./imgs/Banners/banner6.jpg"
import banner7 from "./imgs/Banners/banner7.jpg"
import banner8 from "./imgs/Banners/banner8.jpg"
import banner9 from "./imgs/Banners/banner9.jpg"
.
.
.
import banner(n) from "./imgs/Banners/banner(n).jpg"

export default [
    banner1,
    banner2,
    ...
];

然后将此数组导入到其他文件的一行中：

import banners from './images';
