I have set up a periodically call remote on a page. To get it to stop  
calling I have made it reliant on a hidden element being populated  
with some value, this is all working.

But I want to actually delete the script from the DOM based on a  
decision from the server.

What would be the best way to go about doing this?

Thanks

Regards

Mikel

that should be possible with rjs, shouldnt it?  
like that in the controller:  
page[‘updater’].replace ‘’

\<%= rails updater helper %\>

One way to handle it would be to wrap the periodically\_call\_remote with  
a

\<div id="unique\_id\> and use RJS. Either page.replace or page.replace\_html depending on whether you wanted to get rid of the div entirely or just some of what's inside. \<p\>hth,\<br\> Bill\</p\>

I answered this a couple days ago. Use Google G. and look for  
periodically\_call\_remote and my street name.
