Remove all special characters except space from a string using JavaScript

Remove all special characters except space from a string using JavaScript

You can remove all special characters except spaces from a string in JavaScript using regular expressions. Here's a simple function to achieve that:

function removeSpecialCharactersExceptSpace(str) { // Replace all special characters except spaces with an empty string return str.replace(/[^\w\s]/gi, ''); } // Example usage: const originalString = "Hello! This is a string with *special* characters."; const cleanedString = removeSpecialCharactersExceptSpace(originalString); console.log(cleanedString); // Output: "Hello This is a string with special characters"

In the regular expression /[^\w\s]/gi:

  • [^\w\s]: Matches any character that is not a word character (\w, which includes letters, digits, and underscores) or a whitespace character (\s).
  • gi: Flags for global (match all occurrences) and case-insensitive matching.

This function will remove all special characters except spaces from the input string.
