Webmaster Forum / HTML, CSS, Scripts / JavaScript / October 2006

I am newer to the javascript  scene and i have figured out how to check
if a input box is empty or not but i like display the error right next
to the text box. I am not sure but i think it can be done by making a
div tag right next to it being empty. Anyone have an examples of code
or anything i would greatly appreciate  it. here is what i have so far
for code.

where i want it

<.div id="1"> </div>

javascript

function send_if_valid()
{
    if ( document.forms.newuser.email_a.value == "")
   {
       var str = "bah";
        var obj = document.getElementById("1");
        obj.document.open();
        obj.document.write(str);
        obj.document.close();

   }



}                                              

thanks
