Hi Everyone,

I’m trying to get page.call to work and if i call something like  
page.call ‘alert’, ‘this is a test’  
everything works ok, however when i try calling a function that i  
defined in application.js  
function my\_function(){  
alert(‘this is a test’);  
} i get NameError (undefined local variable or method `my\_function’ for  
#\<ActionView::Base:.

Any idea what i’m doing wrong here. Any input is greatly appreciated.

Thank you,

---

Well just as you wrote page.call ‘alert’ and not page.call alert you  
need to write page.call ‘my\_function’ (I’m assuming that script tag  
isn’t actually in your rjs file as that clearly won’t work)
