You could wrap the image in another element (perhaps a span) and then update that element with a new image as necessary. - Dash - On Dec 20, 11:18 am, Nuno <nuno.f.ne...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, > > I''m trying to refresh an img tag that as a captcha image. > > <img src="captcha.php" align="absmiddle" /> > > How am I able to do this with prototype? > > Thanks > > N--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Hi,
Here is the code:
<span id="cap"><img src="visual-captcha.php"
width="120" height="40"
alt="Captcha" /></span>
<a href="#" onClick="javascript: new
Ajax.Updater(''cap'', ''visual-
captcha.php'', { method: ''get'' });">Change
Image</a>
But it doesn''t work
Any ideas?

Ok, I solve it this way: <img name="captcha" src="visual-captcha.php" width="120" height="40" alt="Captcha" /></span> <a href="#" onClick="javascript: document.images[''captcha''].src ''visual-captcha.php?'' + Math.random();">Change Image</a> I''m not a Javascript man, so .. it works What do you think? Does this works on every browser?
