Hi Everybody,

I am having a tough time in figuring out how to pass ‘this’ java script  
keyword as a parameter to a java script function in page.call.

For instance, in my RJS template I want to do this:  
page.call “myFunctionName”, this

Any help in much appreciated!!!

Thanks!  
-Amit.

For starters you can use page \<\< to insert an arbitrary fragment of  
javascript (and if you find yourself fighting rjs to much you may want  
to just drop it altogether). You could also try page.call ‘foo’,  
page.literal(‘this’)

Thanks Fred!!!

“page.literal(‘this’)” did the trick.

I am working on a fast track project and didn’t had much time to figure  
this out.

I heartily appreciate your reply.

Thanks a lot!!!
