To remove text between two parts of a string, use JavaScript regex.
Example
You can try to run the following code to learn how to remove text between parentheses −
<html> <head> <script> var str = "Welcome to Qries (website)"; document.write(str); // Removing text between parentheses document.write("<br>"+str.replace(/ *\([^)]*\) */g, "")); </script> </head> <body> </body> </html>
