在draft.js中实现链接可以通过使用Entity来实现。Entity是draft.js中的一种特殊对象,用于表示文本中的实体,比如链接、图片等。具体实现步骤如下:
import { EditorState, ContentState, RichUtils, Modifier, Entity } from 'draft-js';
const createLinkEntity = (url) => {
return Entity.create('LINK', 'MUTABLE', { url });
};
const insertLink = (editorState, url) => {
const contentState = editorState.getCurrentContent();
const contentStateWithEntity = contentState.createEntity('LINK', 'MUTABLE', { url });
const entityKey = contentStateWithEntity.getLastCreatedEntityKey();
const newEditorState = EditorState.set(editorState, { currentContent: contentStateWithEntity });
return RichUtils.toggleLink(
newEditorState,
newEditorState.getSelection(),
entityKey
);
};
const handleEditorChange = (newEditorState) => {
setEditorState(newEditorState);
};
const Link = (props) => {
const { contentState, entityKey } = props;
const { url } = contentState.getEntity(entityKey).getData();
return (
<a href={url} target="_blank" rel="noopener noreferrer">
{props.children}
</a>
);
};
const decorator = new CompositeDecorator([
{
strategy: findLinkEntities,
component: Link,
},
]);
<Editor
editorState={editorState}
onChange={handleEditorChange}
decorators={decorators}
/>
通过以上步骤,你可以在draft.js中实现链接功能。当用户输入链接文本时,可以使用insertLink
函数将链接插入到编辑器中。在渲染阶段,使用Link
组件来渲染链接文本,并通过href
属性将链接与实际URL关联起来。
