Remove any spaces while typing into a textbox on a web page

Question

How could I, on the fly, remove spaces entered into a textbox while the person is typing?

Answer 1

$(function() {
  var txt = $("#myTextbox");
  var func = function() {
    txt.val(txt.val().replace(/\s/g, ''));
  }
  txt.keyup(func).blur(func);
});

You have to additionally handle the blur event because user could use context menu to paste ;)
