I have the follwing jQuery:

        $("#textArea").keyup(function(){
            var textAreaValue = $("textArea");
            if(!textArea.value.indexOf("some string")){
                textArea.value = textArea.value.replace("some string",null);
                alert("It was there!");
            }
        });


  • Is it normal for element.value.replace("some string",null); to replace "some string" with "null"as a string? And if normal can you please explain why?

  • I have tested it with element.value.replace("some string",""), and that works fine, so what would be the difference between null and ""?

Thanks in advance.
