正则表达式匹配最后一个空格字符

问题描述

我需要一些帮助.我正在寻找一个匹配字符串中最后一个空格字符的正则表达式.我正在使用 JavaScript 和经典 ASP.

I need some help. I am looking for a regex that would match the last space character in a string. I am using JavaScript and classic ASP.

我有一长串文本，我将其修剪为 100 个字符.如果修剪由于 100 个字符的限制而剪切了一个单词，我想删除最后一个字符以避免拼写错误.

I have a long string of text which I trim to 100 characters. I would like to remove the last character to avoid a spelling mistake if the trim cuts a word due to the 100 characters limit.

regex.replace(/[ ]$.*?/ig, '');

有人有想法吗?谢谢.

推荐答案

根据我的理解，你需要删除最后一个空格和后面的所有内容，对吧?

From my understanding, you need to remove the last space and everything after it, right?

 str = str.replace(/s+S*$/, "")
