Rails spinoffs - Mar 2006 - Returning Javascript

I have a page with some links on it that when clicked, loads a
"subpage" in
a div.  This subpage contains some html and javascript.  I see how using
ajax.updater with evalscripts will run any standalone javascript on the
subpage, but I do not have access to any of the javascript functions on that
subpage.  Is there some way I can make those javascript functions available
to the page?  thanks for any help!

When defining the functions, store them in variables...

 

myFunc = function() {

            //...etc...

}

 

 

That SHOULD work, but others have mentioned having to go the extra step
of assigning them to the window object (which I''m almost convinced in
unnecessary but I don''t use the prototype AJAX stuff - not flexible
enough for my needs). So if the above still does not work, try...

 

window.myFunc = function() {

            //...etc...

}

btw, it worked without having to assign to window, at least in FF and IE6

No problem. Keep that window assignment thing in mind though. You might
run into a situation where your eval statements are running in the scope
of a closure, in which case you might lose those functions if you don''t
assign them to some global object. But I think for the most part you''ll
be safe with just assigning them to variables.
