如何切換antd Typography.Paragraph ellipsis

Question

我正在使用<Typography.Paragraph>組件來顯示列表中某些項目的描述。 我想將描述中的行數限制為 2。

現在我可以使用<Typography.Paragraph>的ellipsis屬性將描述限制為僅顯示 2 行並將其設置為可擴展。 但是，我似乎無法找到一種方法將文本折疊回僅有 2 行的省略號(...)

這是我當前代碼的片段。

const listOfLongText = [.....];

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

我知道Paragraph的ellipsis道具的onExpand回調，但不確定如何使用onExpand在展開和折疊功能之間進行切換

<Typography.Paragraph> API 在這里定義

如果您需要更多信息，請發表評論，我會提供。

Answer 1

當前的antd版本（ 3.23.4 ）沒有這個選項。

您需要通過 state 控制它，例如：

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