regex with space and letters only?

Question

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("");       } });​ 

Answer 1

use this expression

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

Answer 2

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

\s will allow the space
