如何找到3个或更多连续字符? [英] How to find 3 or more consecutive characters?

问题描述

我正在检查密码.这些功能之一是查找是否连续重复输入的密码.我还没有代码，因为我不知道该怎么做.

I'm making a password checking. One of those functions is to find if the inputted password is consecutively repeated. I do not have codes yet because I don't know how to do it.

我发现了这一个 RegEx可以匹配两个或多个相同字符非连续，但只能匹配重复的逗号.

I found this one RegEx match two or more same character non-consecutive but it only match repeated commas.

以下是场景:

5236aaa121-重复模式，因为a连续重复3次

5236aaa121 - Repeated pattern because a is consecutively repeated 3 times

2312aa32aa-无重复字符

2312aa32aa - No repeated character

111111asd-重复模式，因为1被连续多次重复

111111asd - Repeated pattern because 1 is consecutively repeated many times

推荐答案

使用向后引用:/(.)\1\1/

示例:

var hasTripple = /(.)\1\1/.test('xyzzzy');
