英文:
How do you get the word - after a regular expression matched phrase
问题
我想获得匹配短语后面的下一个单词。
示例：我想要改变我的疼痛阈值
-- "改变我的 ***"
let text = "我想要改变我的疼痛阈值";
let firstTriggerregEx = "(?:\\b|')(改变我的)(?:\\b|')";
const found2 = text.match(firstTriggerregEx);
console.log(found2);
这将返回一个匹配，但不包括后面的单词。
英文:
I want to get the next word after the matched phrase.
e.t. - I want to change my pain threshold
-- "change my ***"
let text = "I want to change my pain threshold"
let firstTriggerregEx = "(?:\\b|')(change my)(?:\\b|')";
const found2 = text.match(firstTriggerregEx);
console.log(found2);
This will return a match, but not the word after

你可以使用以下模式：
(?<=\\bchange my )(\\w+)
第一部分是正向后查找。它确保后面的字符/组在指定模式之前。
第二部分包含了“单词字符”（[a-zA-Z0-9_]）的字符集，放在捕获组中，这样你可以稍后检索它。

英文:
You can use the following pattern:
(?<=\\bchange my )(\\w+)
The first part is positive lookbehind. It ensures that the following character/group is preceded by the specified pattern.
The second part consists of the character set for "word characters" ([a-zA-Z0-9_]) within a capture group, so you can retrieve it later.
