var str = "Hello, this is Mike (example)";
alert(str.replace(/\s*\(.*?\)\s*/g, ''));
That'll also replace excess whitespace before and after the parentheses.
这也将替换括号前后多余的空格。

If you need to remove text inside nested parentheses, too, then:
如果您还需要删除嵌套括号内的文本，则：
var prevStr;
do {
prevStr = str;
str = str.replace(/\([^\)\(]*\)/, "");
} while (prevStr != str);
回答by Pascalius
I found this version most suitable for all cases. It doesn't remove all whitespaces.
我发现这个版本最适合所有情况。它不会删除所有空格。
For example "a (test) b" -> "a b"
例如“a（测试）b”->“a b”
"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim();
"Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();
"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim();
"Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();
