When I trigger a paste event in an input field, I have a method that replaces all special characters. However, it is also removing empty spaces between words. How can I prevent this from happening?
checkSpecialCharacters(){
let value = this.form.get("quantity").value.replace(/[^a-zA-Z0-9 ]/g,'').replace(/\s/g,'');
// if value = "testing value"
console.log(value) // returns testingvalue
}
What am I doing wrong here? Does [^a-zA-Z0-9 ] including a space not skip spaces?
The code snippet .replace(/\s/g,''); will eliminate any space character, including normal spaces, newlines, line feeds, and tab characters (both horizontal and vertical). If you wish to keep plain spaces intact, simply omit this part.
To simplify the pattern further, consider using the case-insensitive flag along with \d instead of 0-9.
let value = this.form.get("quantity").value.replace(/[^a-z\d ]/gi, '');
