reactjs - 如何切换 antd Typography.Paragraph 省略号

Question

我正在使用 <Typography.Paragraph>组件显示列表中某些项目的描述。我想将描述中的行数限制为 2。

现在我可以使用 ellipsis <Typography.Paragraph> 的 Prop 将描述限制为仅显示 2 行并将其设置为可扩展。但是，我似乎无法找到一种方法将文本折叠回带有省略号的 2 行 (...)

这是我当前代码的一个片段。

const listOfLongText = [.....];

listOfLongText.map((text,i) => {
    <Paragraph ellipsis={{ rows: 2, expandable: true }}> 
        {text}
    </Paragraph>
})

我知道 onExpand ellipsis 的回调Paragraph的 Prop 但不确定如何使用 onExpand 在展开和折叠功能之间切换

<Typography.Paragraph> API定义here

如果您需要更多信息，请发表评论，我会提供。

当前的antd版本(3.23.4)没有这个选项。

你需要通过状态来控制它，例如:

<Paragraph
  ellipsis={{
    rows: 3,
    expandable: true,
    onExpand: this.typoExpand
  }}
