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.
这样会隐藏部分文字
