Hi

I am relatively new to ruby on rails. I want to use this javascript  
bundle:  
[http://prototype-window.xilinus.com/index.html](http://prototype-window.xilinus.com/index.html)

How would I call those functions in an rjs file?

example:  
win = new Window(‘window\_id’, {title: “Sample”, top:100, left:350})  
win.getContent().innerHTML = “

# Hello world !!
”;  
win.setDestroyOnClose();  
win.showCenter();

Thanks

I think you would use page.call ‘javascript\_to\_be\_evaluated’

with your example I’m guessing something like this would work  
page.call(“win = new Window(‘window\_id’, {title: "Sample", top:100,  
left:350})”)  
etc…etc…  
don’t for get to include the javascript library in your layout  
\<%= include\_javascript\_tag “library\_name\_here” %\>  
And of course, make sure it’s in your rails app javascript folder =)

heres the docs on it:

Woops, I mean  
\<%= javascript\_include\_tag “library\_name\_here” %\>

Hi,

THanks for the input, but that did not work. Does anyone know how to  
get this to work using rjs?

thanks

In an RJS template, I think this outputs JS directly…

page \<\< ‘javascript code goes here’

That does. and it does work, however, I would like to try it without  
dumping straight up javascript code because i could just do it in js  
instead.

thanks

page.replace\_html

are all helper functions. You could write a set of helper functions  
like that for your JS library and then use them in a similar manner.
