使用多字符定界符分割字符串

Question

I want to split a text using delimiters that can be longer than one symbol. 我想使用可以超过一个符号的定界符来分割文本。

For example, this should be split using and , or and comma: 例如，应使用and ， or和逗号将其拆分：

"red lorry, yellow lorry and brown lorry".split(someRegexp)

should produce: 应该产生：

["red lorry", " yellow lorry", "brown lorry"]

It's not necessary for regex to trim spaces, this can be done later. 正则表达式不需要修剪空间，可以稍后进行。

Answer 1

You can use the regex 您可以使用正则表达式

/,|\b\s*(?:and|or)\s*\b/

Example 例

> "red lorry, yellow lorry and brown lorry".split(/,|\b\s*(?:and|or)\s*\b/)
< ["red lorry", " yellow lorry", "brown lorry"]

\\b Matches word boundaries. \\b匹配单词边界。 This ensure that the or and and are not matched within another word. 这样可以确保在另一个单词中的“ or和“ and不匹配。
