在图库组件中，照片对象未通过状态更改。 我创建了一个“文件夹库”，这是一个多库组件，如果您通过单击将其选中，则可以呈现一个新库。
查看演示： https://codesandbox.io/s/50wr02n8q4
github问题： https://github.com/neptunian/react-photo-gallery/issues/118
环境：
请参见下面的代码：
Hover A -> Focus/Enlarged A1, A2, A3
Hover B -> Focus/Enlarged B1, B2
const folderPhotos = [
{
title: "Gallery one",
photos: [
{
src: "https://source.unsplash.com/2ShvY8Lf6l0/800x599"
},
{
src: "https://source.unsplash.com/Dm-qxdynoEc/800x799"
},
{
src: "https://source.unsplash.com/qDkso9nvCg0/600x799"
}
]
},
{
title: "Gallery two",
photos: [
{
src: "https://source.unsplash.com/iecJiKe_RNg/600x799"
},
{
src: "https://source.unsplash.com/epcsn8Ed8kY/600x799"
},

}
]
}
];
维对象：
photoProps这里的内部组件：
const photoProps = {
width: 1,
height: 1
};
现在使用<Gallery
columnsLength={6}
photosObj={folderPhotos}
photoProps={photoProps}
withLightbox={true}
/>
组件：
Gallery我也修复了示例的import _ from "lodash";
import React, { Component, Fragment } from "react";
import Gallery from "react-photo-gallery";
import Lightbox from "react-images";
export class PhotoGallery extends Component {
constructor(props) {
super(props);
// Bindables
this.showGallery = this.showGallery.bind(this);
this.openLightbox = this.openLightbox.bind(this);
this.closeLightbox = this.closeLightbox.bind(this);
this.goToPrevious = this.goToPrevious.bind(this);
this.goToNext = this.goToNext.bind(this);
}
state = {
photosObj: [],
currentImage: 0,
lightboxIsOpen: false
};
async showGallery(itemObj, photoProps) {
let photosObj = [];
if (!_.isEmpty(itemObj)) {
photosObj = await Object.keys(itemObj)
.map(i => itemObj[i])
.map(item => ({
...item,
width: photoProps.width,
height: photoProps.height
}));
this.setState({
photosObj
});
console.log("-- props: ", this.state.photosObj);
}
}
openLightbox(event, obj) {
this.setState({
currentImage: obj.index,
lightboxIsOpen: true
});
}
closeLightbox() {
this.setState({
currentImage: 0,
lightboxIsOpen: false
});
}
goToPrevious() {
this.setState({
currentImage: this.state.currentImage - 1
});
}
goToNext() {
this.setState({
currentImage: this.state.currentImage + 1
});
}
render() {
const { columnsLength, photosObj, photoProps, withLightbox } = this.props;
return (
<div className="section-body">
<div className="content-col-info">
<ul className="list-mentors w-list-unstyled">
{photosObj.map((itemObj, i) => (
<li key={i}>
<span
className="mentors-item w-inline-block"
onClick={() => this.showGallery(itemObj.photos, photoProps)}
>
<div>{itemObj.title}</div>
</span>
</li>
))}
</ul>
</div>
<div className="content-col-info">
{!_.isEmpty(this.state.photosObj) && (
<Gallery
columns={columnsLength}
photos={this.state.photosObj}
onClick={withLightbox ? this.openLightbox : null}
/>
)}
{!_.isEmpty(this.state.photosObj) && withLightbox && (
<Lightbox
images={this.state.photosObj}
onClose={this.closeLightbox}
onClickPrev={this.goToPrevious}
onClickNext={this.goToNext}
currentImage={this.state.currentImage}
isOpen={this.state.lightboxIsOpen}
/>
)}
</div>
</div>
);
}
}
export default PhotoGallery;
组件道具。
Gallery并称之为：
loadGallery(columnsLength) {
import("./photo-gallery").then(Gallery => {
console.log("-- load gallery: ", this.state.photosObj);
return (
<Gallery.default
columnsLength={columnsLength}
photosObj={this.state.photosObj}
withLightbox={true}
/>
);
});
}

因为在Gallery.js（库）中需要照片选项
Gallery.propTypes = {
photos: _propTypes2.default.arrayOf(_Photo.photoPropType).isRequired,
direction: _propTypes2.default.string,
onClick: _propTypes2.default.func,
columns: _propTypes2.default.number,
margin: _propTypes2.default.number,
ImageComponent: _propTypes2.default.func
};
在Gallery.js（您的js文件）的<Gallery />中传递“ photos = {this.state.photosObj}”，如下所示：
代码：
<Gallery
columnsLength={columnsLength}
photosObj={this.state.photosObj}
photos={this.state.photosObj}
withLightbox={true}
/>
我不确定您为什么要通过其他选择。
