regex with space and letters only?

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-Z\s]*$/;

Update: 27-April-2023

function validate(){
  const regEx1 = /[^a-zA-Z\s]+/;
    input.value = input.value.replace(regEx1, '');
}
<input id="input" type="text" onkeyup="return validate();">

regex expression:

var reg_name_lastname = /^[a-zA-Z\s]*$/;

Validation to the user_name input field

if(!reg_name_lastname.test($('#user_name').val())){ //
    alert("Correct your First Name: only letters and spaces.");
    valid = false;
}

Allowed only characters & spaces. Ex : Jayant Lonari

if (!/^[a-zA-Z\s]+$/.test(NAME)) {
    //Throw Error
}

$('#input').on('keyup', function() {
     var RegExpression = /^[a-zA-Z\s]*$/;  
     ...

});

\s will allow the space
