如何在javascript中制作正则表达式来重复(how to make an regular expression in javascript to repeat)

如何使其验证此字符串：

word:word,word:word,

我写的这篇文章仅适用于：

word:word,enithinggg

这是错的。

/^(^([0-9a-zA-Z!\? ])+\:([0-9a-zA-Z!\?. ])+\,)+$/i

How can I make it to validate this string:

word:word,word:word,

What I wrote this and works only for:

word:word,enithinggg

which is wrong.

/^(^([0-9a-zA-Z!\? ])+\:([0-9a-zA-Z!\?. ])+\,)+$/i

最满意答案

/^(([0-9a-zA-Z!\?])+\:([0-9a-zA-Z!\?])+\,?)+$/

应该这样做。 你在第一组中有^ ，强迫它匹配换行符。 我对javascript正则表达式不太熟悉，所以我不确定最后i在做什么。

您可以在http://rubular.com上运行快速测试

/^(([0-9a-zA-Z!\?])+\:([0-9a-zA-Z!\?])+\,?)+$/

should do it. You had ^ inside the first group, forcing it to match a newline. I'm not too familiar with javascript regular expressions, so I'm not sure what the i at the end was doing.
