我正在使用"react-image-lightbox"制作画廊。首先,我使用 Material-Ui 中的 Grid 显示图像,然后按照https://www.npmjs.com/package/react-image-lightbox 中的文档进行操作。 但是,我无法在单击下一个或上一个时相应地更改图像标题。关于我如何解决那部分的任何线索?
import img1 from "../../Image/Process/image1.jpg";
import img2 from "../../Image/Process/image2.jpg";
import img3 from "../../Image/Process/image3.jpg";
const images = [img1, img2, img3];
class GalleryPage extends React.Component {
constructor(props) {
super(props);
this.state = {
photoIndex: 0,
isOpen: false,
caption: null
};
}
render() {
const { photoIndex, isOpen, caption } = this.state;
return (
<div className="gallery-section" id="gallery">
<div className="mdb-lightbox">
