javascript - 拆分字符串但保留逗号

Question

我需要拆分一个保留非空格的句子字符串，例如. 或,。我需要将它们包含在要拆分的数组字符串中。不在它们自己单独的数组索引中。

const regex = /\W(?:\s)/g

function splitString (string) {
  return string.split(regex)
}

console.log(splitString("string one, string two, thing three, string four."))

// Output ["string one", "string two", "thing three", "string four."]
// Desired ["string one,", "string two,", "string three,", "string four."]

Answer 1

也许使用匹配方法而不是拆分方法:

"string one, string two, thing three, four four.".match(/\w+(?:\s\w+)*\W?/g);
// [ 'string one,', 'string two,', 'thing three,', 'four four.' ]

或更具体的(这样您可以轻松选择一个或多个分隔符):

"string one, string two, thing three, four four.".match(/\S.*?(?![^,]),?/g);
