我正在使用一个新闻 API，由于字符限制，它部分回复了截断的文本。它们以 '...'、'[...]' 或没有任何指示结尾。

我想在最后一句之后切断所有内容，所以我有干净的文字。

这是我当前的代码：

var shortenText = function (input) {
        if (input.search(/\w+\./) > 0) {
            return input.substring(0, input.lastIndexOf('.') + 1);
        } else {
            return input
        }
    }

问题是，日期（2 月 2 日）、数字（2.000）或美国搞砸了我的输出。

我需要类似 lastIndexOf(/\w+.\w+./g) 的东西来找到最后两个单词，然后用句号来确定句子结束。但是 lastIndexOf 不适用于正则表达式。：/

任何想法如何解决这个问题？

谢谢！

编辑：以下是 API 响应的一些示例：
