Embedding Question Marks in Query Strings

Rails
1

I have an Ajax updater using observe_field:

<%= text_area_tag('ubb', nil, :size => '60x40') %> <%= observe_field(:ubb, :url => {:action => 'render_preview'}, :frequency => 0.5, :update => 'preview', :with => 'ubb') %>

This all works great until the text in the textarea contains a
question mark. For example:

Can I use a question mark?

At which point, it seems not to be submittable using the Ajax helpers
because I get nothing in the params hash.

Anyone had this problem/found workarounds?

Thx

So it is… Thanks. In case anyone else runs into this, if you expect
any non-URL-safe characters in your Ajax request, use this:

:with => “‘text=’ + encodeURIComponent($(‘myfield’).value)”

in your observe_field method call. Out of the box, all characters are
passed through unmodified.
