JavaScript/regex: Remove text between parentheses

Would it be possible to change

Hello, this is Mike (example)

to

Hello, this is Mike

using JavaScript w开发者_JAVA百科ith Regex?

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Result:

"Hello, this is Mike"

var str = "Hello, this is Mike (example)";

alert(str.replace(/\s*\(.*?\)\s*/g, ''));

That'll also replace excess whitespace before and after the parentheses.

Try / \([\s\S]*?\)/g

Where

(space) matches the character (space) literally

\( matches the character ( literally

[\s\S] matches any character (\s matches any whitespace character and \S matches any non-whitespace character)

*? matches between zero and unlimited times

\) matches the character ) literally

g matches globally

Code Example:

var str = "Hello, this is Mike (example)";
str = str.replace(/ \([\s\S]*?\)/g, '');
console.log(str);

.as-console-wrapper {top: 0}

If you need to remove text inside nested parentheses, too, then:

        var prevStr;
        do {
            prevStr = str;
            str = str.replace(/\([^\)\(]*\)/, "");
        } while (prevStr != str);

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();
