JavaScript/regex: Remove text between parentheses
JavascriptRegexJavascript Problem Overview
Would it be possible to change
Hello, this is Mike (example)
to
Hello, this is Mike
using JavaScript with Regex?
Javascript Solutions
Solution 1 - Javascript
"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");
Result:
"Hello, this is Mike"
Solution 2 - Javascript
var str = "Hello, this is Mike (example)";
alert(str.replace(/\s*\(.*?\)\s*/g, ''));
That'll also replace excess whitespace before and after the parentheses.
Solution 3 - Javascript
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}
Solution 4 - Javascript
If you need to remove text inside nested parentheses, too, then:
var prevStr;
do {
prevStr = str;
str = str.replace(/\([^\)\(]*\)/, "");
} while (prevStr != str);
Solution 5 - Javascript
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();
