I made a regular expression that only accepts letters. I'm not really good in regex, thats why I don't know how to include spaces in my regex.

My HTML:

<input id=input />

My js / jQuery code:

$('#input').on('keyup', function() {

      var RegExpression = /^[a-zA-Z]*$/; 



      if (RegExpression.test($('#input').val())) {



      } 

      else {

          $('#input').val();

      }

});

use this expression

var RegExpression = /^[a-zA-Zs]*$/;

Update: 27-April-2023

function validate(){

  const regEx1 = /[^a-zA-Zs]+/;

    input.value = input.value.replace(regEx1, '');

}

<input id=input type=text onkeyup=return validate();>
