Javascript正则表达式或其他解析技术来提取字符串中最后一组括号的内容

Question

I need to extract the rightmost parenthetical (the last one) from a string that has 1-N parentheticals.

For example, in Some title (8888)(123, bar)(1000, foo) I want to get the contents of the last set of parentheses, ie 1000, foo . There will always be at least one parenthetical, but may be more than one.

I am fine with using regex, or other string parsing techniques.

Answer 1

Assuming they are not nested you can simply do: /\\(([^\\)]+)\\)$/

var foo = "Some title (8888)(123, bar)(1000, foo)";
// Get your result with
foo.match(/\(([^\)]+)\)$/)[1];

Answer 2

follow this link

you will see with that regex .*\\((.+)\\) you can get $1(group one) as your wanted content

Answer 3

Match all parentheticals, and get the last one.

> 'Some title (8888)(123, bar)(1000, foo)'.match(/\(.*?\)/g).pop()
"(1000, foo)"

> var x = 'Some title (8888)(123, bar)(1000, foo)'.match(/\(.*?\)/g).pop(); x.substr(1, x.length-2)
"1000, foo"
