How to I change the button into hypertext in RoR

Question

Here is the code for generate button, but I want it in a hyper text, how to modify this?

<% form_remote_tag (:url => { :action => :choose_category, :id => category }) do %>
  <%= submit_tag  category.name %>
<% end %>

I tried to use the link_to, but it can't submit a post method, what can I do?

Answer 1

Hyperlinks do not have the ability to submit POSTs (not in any browser that I know of, at least). Forms are usually the best way to POST some data.

What you can do, however, is create a form on your page (with the appropriate methods and fields), then create a hyperlink with an onclick handler that will submit the form. I'm not familiar with RoR to give you an example, but it should be a trivial change to the standard hyperlink-generating function.

(Note that the onclick handler should return false to prevent the link itself being followed; and ideally the href of the hyperlink would go to some acceptable page if people have Javascript disabled.)

Answer 2

Links can't technically submit forms. That means you're limited to javascript, check out link_to_function. You'll need the id of the form you want to submit and then you can write some javascript like:

$('the_forms_id').submit(); return false;

If I understand correctly, you want replace the submit button in your posted code with a regular hyperlink (<a> tag). Check out link_to_remote. To understand the javascript code that generates, you may also want to check out the docs for Prototype's Ajax.Updater.
