Js高级字符串拆分

Question

我有一个来自.txt文件的长字符串,其中包含我要分割的几个句子和日期.

语法是这样的

01-01-15: Here is some text
02-01-15: Here is some other text
05-06-17: Here is some new text
06-06-17: Here is some text
taking up 
several lines
07-06-17: And so on

由于有些句子占用了几行而我无法使用text.split("\n")- 但我能做些什么呢？所有句子都以xx-xx-xx开头,其中x是数字.

Answer 1

您可以通过使用先行模式搜索每个逻辑单元的开始日期来拆分行.

var data = '01-01-15: Here is some text\
02-01-15: Here is some other text\
05-06-17: Here is some new text\
06-06-17: Here is some text\
taking up \
several lines\
07-06-17: And so on';


console.log(data.split(/(?=\d\d-\d\d-\d\d:)/));
