正则表达式字符串之间的所有内容
我有一个可以以两种不同方式查看的字符串：
foo=bar (everything after "=" including any other character)
or
foo=bar&bar (everything between "=" and "&")
我想在这种特殊情况下使用正则表达式，如何替换 foo 的值
I have a string that can look in two different ways:
foo=bar (everything after "=" including any other character)
or
foo=bar&bar (everything between "=" and "&")
I would like to use a regexp for this particular case, how could I replace the value of foo

匹配
(foo)=([^&]+)将捕获foo以及等号相应右侧内容的值。我不确定你到底想用它做什么。Matching
(foo)=([^&]+)will capturefooand the value of the stuff on the corresponding right-hand side of the equals sign. I'm not sure exactly what you're looking to do with it.
