jQuery filter asterisk (*) input

Question

I have here a jQuery code that filter special characters:

$("#txtFName").keyup(function () {
      name = $("#txtFName").val();
      name = name.replace(/[^a-zA-Z 0-9.]+/g, '');
      $("#txtFName").val(name);
});

But I only wanted to filter the asterisk (*) character and the remaining are allowed. What adjustment should I do in /[^a-zA-Z 0-9.]+/g to make this? Or there are other work around to do this? Thank you very much!

Answer 1

So you only need to replace * :

$("#txtFName").keyup(function () {
  $(this).val($(this).val().replace(/\*/g, ''));
});
