The problem is that you have no event to fire the function.
Try..Code:<% test = 1 %> <html> <head> <SCRIPT LANGUAGE="JavaScript"> function enb() { document.form1.send.disabled=true; } </SCRIPT> </head> <body <% IF test=1 THEN %> onLoad="enb()" <% ELSE %> <% END IF %> > <form name="form1" id="form1" action="test.asp?action=called" method="GET"> <input type="button" name="send" id="send" value="send" /> </form> </body> </html>Last edited by jhardman; Oct 6 '08, 05:40 PM.

Snester is right, and this is actually a common goof. You see, ASP is executed on the server and javascript is executed on the browser. Snester's approach of adding the javascript function call to the body onload event (conditionally, using asp) is the best way to solve this problem.

Thanks for your answer about calling tha javascript but im still in same problem i need to enable the send button in the page after checking the captcha text without submitting all the form content so i need to call the javascript function from server sideComment

You can't. Javascript is executed on the client, not on the server. I know of no captcha that is processed with javascript. There is not an active connection between the browser and the server, the form has to be submitted after the captcha is filled in order for the server to see what the user entered. It might be possible to do something like this with ajax, but then you would be asking in the wrong forum.

If I've understood you correctly then you could 'disable' the button by checking the condition that decides whether or not to display it and if it's true write the html that displays it. If it's not true then you can display an image that looks like the disabled button instead.
Not sure if this sorts your problem out as i'm answering this in a hurry but I hope so :-)

DrB, I think he is saying he has a "captcha" or "text capture to block automated submissions" and he wants to check it against a value on the server while neither submitting the whole form nor putting the correct answer anywhere on the page (he doesn't want the javascript function to have the answer). Using just ASP you would need to submit the whole form to check the "captcha". It is possible that this sort of thing could be handled with Ajax, but I definitely don't know how to do that.
