echo "<script language=\"JavaScript\" type=\"text/javascript\">document.getElementById('username').style.border='2px solid #FF0000';</script>";

That line would have to be echoed AFTER the line where your tag is with the id of "username." Also, the language property is deprecated so you only need the type property.

You can't use that kind of syntax with JavaScript. That's CSS, not JavaScript. :-\

its called through ajax. i suppose that is the problem. any idea how to make it work.

It doesn't matter what it's called through. In JavaScript:

border='2px solid #FF0000';

You can't use that syntax.

 

http://www.w3schools.com/css/css_border.asp

Use that site to specify each border values separately with JavaScript. That's the only way with JavaScript alone.

 

The other way is to make a CSS class or ID with that value and just add the class using JavaScript.

sure you can...it's perfectly fine to add a border with that syntax. the probably probably has to do with your AJAX. the javascript won't evaluate when you load it with standard AJAX methods. you have to parse the JS out of the contents returned and eval() it. i would use a JS library like jQuery or Prototype, as they will do this for you automatically.
