React初学者在这里。因此,基本上,我希望有3列的元素,可以拖动到同一列内重新排序或移动到不同的列。它的代码被分成两个类,以分隔每个列中应该包含的相关元素。
下面是定义每列结构的类(Swimlane.js)的代码:
import React from 'react';
import Card from './Card';
import Dragula from 'dragula';
import './Swimlane.css';
export default class Swimlane extends React.Component {
render() {
const dragulaDecorator = (componentBackingInstance) => {
if (componentBackingInstance) {
let options = {
moves: function (el, source, handle, sibling) {
return true;
},
accepts: function (el, target, source, sibling) {
return true;
},
direction: 'vertical',
copy: false,
copySortSource: false,
revertOnSpill: false,
removeOnSpill: false,
mirrorContainer: document.body,
ignoreInputTextSelection: true,
}
console.log('componentBackingInstance: ');
console.log(componentBackingInstance);
Dragula([componentBackingInstance]);
}
};
const cards = this.props.clients.map(client => {
return (
<Card
key={client.id}
id={client.id}
name={client.name}
description={client.description}
status={client.status}
/>
);
})
return (
<div className="Swimlane-column" class="Swimlane Column">
<div className="Swimlane-title">{this.props.name}</div>
<div className="Swimlane-dragColumn" ref={dragulaDecorator}> {/* this is the column that contains all my elements, and the one I want to make my container */}
{cards}
</div>
</div>);
}
}在下一个类Board.js中调用Swimlane.js来实际呈现所有组件。
import React from 'react';
import Dragula from 'dragula';
import 'dragula/dist/dragula.css';
import Swimlane from './Swimlane';
import './Board.css';
export default class Board extends React.Component {
constructor(props) {
super(props);
const clients = this.getClients();
this.state = {
clients: {
backlog: clients.filter(client => !client.status || client.status === 'backlog'),
inProgress: clients.filter(client => client.status && client.status === 'in-progress'),
complete: clients.filter(client => client.status && client.status === 'complete'),
}
}
this.swimlanes = {
backlog: React.createRef(),
inProgress: React.createRef(),
complete: React.createRef(),
}
}
getClients() {
return [
// [id, name, description, status]
['1','Name 1','Description 1', 'backlog'],
['2','Name 2','Description 2', 'in-progress'],
['3','Name 3','Description 3', 'backlog'],
['4','Name 4','Description 4', 'complete'],
].map(companyDetails => ({
id: companyDetails[0],
name: companyDetails[1],
description: companyDetails[2],
status: companyDetails[3],
}));
}
renderSwimlane(name, clients, ref) {
return (
<Swimlane name={name} clients={clients} dragulaRef={ref}/>
);
}
render() {
return (
<div className="Board">
<div className="container-fluid">
<div className="row">
<div className="col-md-4">
{this.renderSwimlane('Backlog', this.state.clients.backlog, this.swimlanes.backlog)}
</div>
<div className="col-md-4">
{this.renderSwimlane('In Progress', this.state.clients.inProgress, this.swimlanes.inProgress)}
</div>
<div className="col-md-4">
{this.renderSwimlane('Complete', this.state.clients.complete, this.swimlanes.complete)}
</div>
</div>
</div>
</div>
);
}
}因此,renderSwimlane()方法使用getClients()方法来生成一个“状态”属性和一个“泳道”属性,用于呈现3列,所有列都包含相关信息。
现在,如果我运行这段代码,三个'Swimlane-dragColumn‘div中的所有可拖动元素都可以在它们自己的容器中排序,但不能移动到其他容器中。此外,请忽略导入Card.js的语句,它是一个基本上显示每个可拖动元素应该是什么样子的类(颜色等)。
这里(how to move a dragula draggable element to another div in react-dragula?)也问了一个类似的问题,但我不明白答案是什么意思(由于缺乏声誉,我不能发表评论)。如何将类名为“Swimlane-dragColumn”的所有三列都呈现为可行的容器?我发现我应该在某个地方使用'push‘函数,但我不知道如何实现它。
谢谢

componentDidMount(){
Dragula(Array.from(document.getElementsByClassName('Swimlane-dragColumn')))
}
componentDidUpdate(){
Dragula(Array.from(document.getElementsByClassName('Swimlane-dragColumn')))
}我相信这是来自sherpa内部的,任务是与react挂钩相关的,试着这样做,然后继续工作。

如果你愿意添加库,我在这里写了这个:https://github.com/jpribyl/react-hook-dragula
它提供了强类型,并允许您在react环境中轻松地使用dragula。它只给你的捆绑包增加了22kb (假设你已经有了react + dragula)
在我看来,你只需要多个容器就能达到你想要的结果。本演示中的第一个示例应该类似:https://johnpribyl.com/react-hook-dragula/
此处提供的代码:https://github.com/jpribyl/react-hook-dragula/blob/main/example/src/examples/TwoContainerExample.tsx
如果有什么不清楚的地方,请告诉我!我相信你的解决方案应该是这样的:
<Dragula className="row">
<DragulaContainer className="col">
<Draggable>
column 1
</Draggable>
</DragulaContainer>
<DragulaContainer className="col">
<Draggable>
column 2
</Draggable>
</DragulaContainer>
<DragulaContainer className="col">
<Draggable>
column 3
</Draggable>
</DragulaContainer>
