My Code is here

\<% for category in @categories %\> \<% end %\>

| \<%= radio\_button 'category', 'id', category.id %\>\<%= h category.name %\> |

  
\<%= link\_to\_remote 'Edit', :update =\> 'category', :url =\> { :action =\> 'edit', :id =\> category[id]} %\>

I don’t get the radio\_button’s value, how can I get radio\_button’s value  
in  
link\_to\_remote?

\<%= link\_to\_remote ‘Edit’,  
:update =\> ‘category’,  
:url =\> { :action =\> ‘edit’, :id =\> category[id]},  
:with =\> “‘id=’ + $(‘id\_of\_your\_element\_here’).value”

There is still a problem. I inspect the DOM, that is

 root root2 root3 root4 

as you can see, I can’t use $() to get the radio value because the id is  
dynamic created
