I found myself doing a lot of long :with strings with link_to_remote
when passing multiple parameters from the page by dom ids. This
strings are really easy to mess up so I added a behavior to
link_to_remote that allows me to pass a hash to the :with parameter
like this ->
link_to_remote “click me”,
:url => {:action => ‘some_action’},
:with => {:parameter => :some_dom_id,
:another_parameter => :another_dom_id,
“a[hash][parameter]” => :dom_id_3}
I added this to environment.rb
ActionView::Helpers::PrototypeHelper.class_eval do
def link_to_remote_with_with_hash(text, args)
if Hash == args[:with].class
args[:with] = “’” << args[:with].collect{|var, val|
“#{var}=’ + encodeURIComponent($(’#{val}’).value)”
}.inject{|str, el|
str << " + '&#{el}"
}
end
link_to_remote_without_with_hash(text, args)
end
alias_method_chain :link_to_remote, :with_hash
end
Just thought I’d share it.
