如何在javascript中拆分包含多个规则的字符串 [英] How to Split string with multiple rules in javascript

问题描述

我有这个字符串例如：

str = "my name is john#doe oh.yeh";

我正在寻找的最终结果是这个数组：

the end result I am seeking is this Array:

strArr = ['my','name','is','john','&#doe','oh','&yeh'];

这意味着适用2条规则：

which means 2 rules apply:

1. 在每个空格后拆分（我知道如何）


2. 如果有特殊字符（。或＃）那么也会拆分但是添加字符&在带有特殊字符的单词之前。

1. split after each space " " (I know how)
2. if there are special characters ("." or "#") then also split but add the characther "&" before the word with the special character.

我知道我可以strArr = str.split（）第一条规则。但我该如何做其他伎俩？

I know I can strArr = str.split(" ") for the first rule. but how do I do the other trick?

谢谢，
Alon

thanks, Alon

推荐答案

假设结果应为'& doe'而不是'& #doe' ，一个简单的解决方案就是用& 。和＃ code>按空格分割：

Assuming the result should be '&doe' and not '&#doe', a simple solution would be to just replace all . and # with & split by spaces:

strArr = str.replace(/[.#]/g, ' &').split(/\s+/)

/ \s + / 匹配连续的空格而不是一个。

/\s+/ matches consecutive white spaces instead of just one.

如果结果应为'& #doe'和'& .yeah'使用相同的正则表达式并添加捕获：

If the result should be '&#doe' and '&.yeah' use the same regex and add a capture:

strArr = str.replace(/([.#])/g, ' &$1').split(/\s+/)
