React Ant 设计标签点击并显示到文本区域
React Ant design tag click and showing to text area
我正在为 Ant design,
使用我的 React TypeScript 项目
这是我的冲突,我想点击标签并将其显示到文本区域,所以当我输入文本然后点击标签时,接下来输入文本并点击标签,
有人知道解决方案吗?
谢谢

import moment from 'moment';
const { TextArea } = Input;
const CommentList = ({ comments }) => (
<List
dataSource={comments}
header={`${comments.length} ${comments.length > 1 ? 'replies' : 'reply'}`}
itemLayout="horizontal"
renderItem={props => <Comment {...props} />}
/>
);
const Editor = ({ onChange, onSubmit, submitting, value }) => (

您需要将点击处理程序添加到 Tag
并且每当它被点击时您将其值附加到 textarea
:
addTag = e => {
const txt = e.target.innerHTML;
this.setState(prevState => ({
...prevState,
value: `${prevState.value} <${txt}> `,
}));
}
<Tag onClick={this.addTag} color="magenta">First Name</Tag>
<Tag onClick={this.addTag} color="red">Last Name</Tag>
<Tag onClick={this.addTag} color="volcano">NIC</Tag>
<Tag onClick={this.addTag} color="orange">FAX</Tag>

是的,正如 Taki 已经提到的,您必须在标签上附加事件侦听器以侦听点击事件,然后相应地处理该点击事件。
或者,如果您还想在标签上绑定一些数据,那么您可以在 html 元素上使用 data-
属性。阅读 using data attributes.
<div>
<Tag color="magenta" data-value="John" onClick={this.onTagClick}>
First Name
</Tag>
<Tag color="red" data-value="Cena" onClick={this.onTagClick}>
Last Name
</Tag>
<Tag color="volcano" data-value="123123" onClick={this.onTagClick}>
NIC
</Tag>
<Tag color="orange" data-value="999999" onClick={this.onTagClick}>
FAX
</Tag>
</div>
onTagClick = e => {
const dataValue = e.target.dataset.value;
this.setState(previousState => ({
value: previousState.value.concat(dataValue)
}));
};
