jquery按长度限制文本

2022-01-12 00:00:00 text formatting jquery css

我可以在使用 jQuery 的多个字符之后隐藏 DIV 中的文本吗?

Can i hide text in a DIV after a number of characters with jQuery?

到目前为止，我认为它会是这样的——jQuery 会循环遍历文本，直到达到一定数量的字符.然后它将从该位置包装一个 DIV 到文本的末尾，然后可以使用 hide() 方法将其隐藏.我不确定如何插入该环绕文本.

So far I think it would go something like this - jQuery would cycle through the text until it gets to a certain number of characters. It would then wrap a DIV from that position to the end of the text which could then be hidden with the hide() method. I'm not sure how to insert that wrapping text.

也将不胜感激.

谢谢.
