我试图将一长串文本截断到一定长度,但也希望确保截断的结果在空格处结束.之后我还要附加一个省略号.

例如:

"This is a very long string that has more characters than I want in it."

成为这个:

"This is a very long string that..."

我从这开始,但显然这不涉及在空格上结束字符串的问题.

<%= item.description[0..30] %>&hellip;

我正在抓取一些网站,并有ASCII文本,我想转换为纯文本存储在数据库中.比如我想要的

I have got to tell anyone who will listen that this is
one of THE best adventure movies I've ever seen.
It's almost impossible to convey how pumped I am
now that I've seen it.

转换成

I have got to tell anyone who will listen that this is
one of THE best adventure movies I've ever seen. It's
almost impossible to convey how pumped I am now that
I've seen it.

我用手指搜索血腥,有什么帮助吗？
