i have some items that use the link\_to\_remote helper and i would like  
them to also link directly to the page that they are calling if  
javascript is not available. i have tried putting the action and id in  
like i would with a regular link\_to helper but that didn’t work.

how can i accomplish this?

found it.

i added: :href =\> url\_for(:action =\> ‘show\_links’, :id =\> link\_cat) to  
the helper and it works beautifully.

I’ve done this before, here is an example:

\<%= link\_to\_remote s.name, {:url =\> {:action =\> “view”, :id =\> s}},  
{:href =\> url\_for(:action =\> “index”, :id =\> s)} %\>

Note the extra braces to separate which hash is which. Actually I  
don’t think the braces arount :href are necessary, but I’m leaving them  
because I know this works because it’s cut and paste from an actual  
app.

Link to remote allows you to add additional html attributes to the tag:

link\_to\_remote “Delete this post”, :update =\> “posts”,  
:url =\> { :action =\> “destroy”, :id =\> post.id },  
{:href =\> url\_for(…)}

Note the href above.

Using tabs i had to put in the class name in to link\_to\_remote  
BTW. just to understand this definition for link\_to\_remote

name, options = {}, html\_options = {} - which means that there are 2  
types of options there which to be used like that { :update =\>  
“div\_name”, :url =\> {…}} and html\_options  
{:class =\> “class\_name”,:href =\> url\_for(…)}

So thats how I put in my class name

\<%= link\_to\_remote “Parent”,  
{:update =\> “tabs”,:url =\> {:action =\>  
“show\_parent”}},  
{:class =\> “active”} %\>  
BTW, if you are to disable class parameter you can send in nil ( :class  
=\> nil )

Note: Thats was not intended as tutorial - just something for me to  
remember in the future.

Take a look at UnobtrusiveJavascript for rails.

It’s perfect for what you’re looking to do.

Forms:  
\<%= form\_remote\_tag(:url =\>{:action =\> “myaction”}, :html =\> {:action  
=\> url\_for(:action =\> “myaction”), :id =\> “myform”}) %\>

Links:  
link\_to\_remote(“mylink”,{:url =\> {:action =\> “myaction”}},{:href =\>  
url\_for(:action =\> “myaction”)})
