我从HTML格式的远程API得到响应。除非您按 阅读更多 按钮,否则不应显示全部内容 响应如下所示:
"<p>A suspension concentrate (SC) formulation containing 450 g/litre of napropamide (41.4% w/w) for the control of annual grass and broad-leaved weeds in winter oilseed rape.</p>\r\n<p><strong>DIRECTIONS FOR USE</strong><br /> IMPORTANT: This information is approved as part of the product label.

我使用react-native-render-html
库进行渲染,不幸的是,该库没有numberOfLines
道具。
我尝试了在Github上建议的解决方案,该解决方案包括添加自定义渲染器,以用本机<p>
标签替换所有<Text>
标签,该标签具有我需要的numberOfLines道具:
<HTML
html={`<p>${description}</p>`}
renderers={{p: (_, children) => <Text numberOfLines={5}>{children}</Text>}}
/>
它起作用了,但问题是我的<p>
变量中有几个description
标签,它显示所有标签都缩短到我输入的行数,而不是缩短了整篇文章。因此,我认为必须使用唯一的标签来包装整个HTML内容,然后应用相同的逻辑
<HTML
html={`<section>${description}</section>`}
renderers={{section: (_, children) => <Text>{children}</Text>}}
/>
同样,该解决方案有效,但它弄乱了内部内容。没有应用换行符,等等。
再经过几次Google搜索后,偶然发现了名为react-native-read-more-text
的第三方库
我了解它仅适用于<Text>
标记内的内容,因此我再次使用模板字符串
<Text>
包装
<ReadMore
numberOfLines={10}
renderTruncatedFooter={renderTruncatedFooter}
renderRevealedFooter={renderRevealedFooter}>
<HTML
html={`<Text>${description}</Text>`}
/>
</ReadMore>
这次我收到一个错误:
我将不胜感激
答案 0 :(得分:0)
我的建议是不要弄乱react-native-render-html,而是执行以下操作:
