hey!

clicking “login” opens (ajax) a login form (partial) on my site.

this partial includes the form and javascript block.  
looks like this:

the problem is: if i try to call the validate-function from inside the  
form (\<input onkeyup=“validate()”…) i’m getting a js error:

validate() is not defined

Why isn’t that function available on my site after the partial is loaded  
?

thx alot

Rendering a partial with Ajax usually requires the evalScripts parameter  
([Prototype API Documentation | String#evalScripts (Deprecated URL)](http://prototypejs.org/api/string/evalScripts)).

I’d give that a try, otherwise just include that javascript method in  
the initial page where you render the login form, that way the  
javascript will surely be evaluated.

Hope that helps,
