I am new to javascript and web development in general and got a couple of questions. 1. Would this be a sane way to achieve the objective? 2. How would I get more elements into the function like lastname? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <script type="text/javascript"> function see_red() { var input = document.getElementById('firstname'); if (input.value.length < 2) { input.style.border='2px solid red'; return false; } else { input.style.border='2px solid green'; return true; } } function see_green() { var input = document.getElementById('firstname'); if (input.value.length < 2) { input.style.border='2px solid red'; return false; } else { input.style.border='2px solid green'; return true; } } </script> <body> <form id="form1" name="form1" method="post" action=""> <p><input type="text" name="firstname" id="firstname" onclick="see_red()" onchange="see_green()" /></p> <p><input type="text" name="lastname" id="lastname" /></p> <p><input type="text" name="email" id="email" /></p> <p><textarea name="msg" cols="30" rows="5" id="msg"></textarea></p> <p><input type="submit" name="submit" id="button" value="Submit" /></p> </form> </body> </html>
