This is an interesting problem:

I have a view that has a div that gets replaced by innerhtml using a  
settimer() in js.

The settimer() invokes a js function (makemytable())that creates a  
table in html based on json data that gets written on the server every  
2 seconds.

So, every 2 seconds, the table in the div in the view automatically  
updates itself. So far, tres bien, very good.

Now, I need to put links in some of the cells in the table – but I  
want them to be effectively link\_to\_remote’s.

So waht I need to do is, since this innerhtml is finished html/js and  
not ruby code, I need to put these link\_to\_remotes in in a pure js  
manner from within makemytable(), which is itself a js.

So my question, the must be a way within js to replicate what  
link\_to\_remote creates, no? How can I write out the finished page, in  
effect, with links that operate like link\_to\_remote? Does anyone know  
what that looks like? If I simply look at the source of a page I have  
with a link\_to\_remote on it I see:

\<a href="#" onclick="new Ajax.Request(’/channels/userfreeze’,  
{asynchronous:true, evalScripts:true, parameters:‘authenticity\_token=’

- encodeURIComponent  
(‘xgorbWtiTdb15yhJ9il0TbbD1szBHSAcWb7p6GVffF0=’)}); return false;"  
style=“float: right; border-style: ridge; padding: 1px;” title=“Make  
user in box below be frozen” type=“submit”\> ![Freeze]()

I assume I only need copy this text, altering what needs to be altered  
interms of where I wantt it to call, etc. But what is the  
authenticity\_token? I am using AUthLogic plugin, could it be from  
that?. Is that necessary here to put that text in too? -Janna B

Janna, it’s actually a feature of Rails to prevent  
cross site request forgery (CSRF)_. You can find_  
more details here:

Good luck,
