Hi
I couldn't figure out, how to create a drop-down list with Markaby.
How
would I create something like this:
<select name="character">
<option value="marvin">Marvin the paranoid Android</option>
<option value="arthur">Arthur Dent</option>
<option value="zaphod">Zaphod Beeblebrox</option>
<option value="trillian">Tricia McMillan</option>
<option value="ford">Ford Prefect</option>
</select>
Here's a helper method I use with Camping. You can pass in a simple
array if your value matches your display text like ["value1",
"value2", ...], or nested array pairs of [ ["value1",
"display1"], ... ] if they don't.
def select_form(action, label_text, field_name, option_list,
button_text = "Submit")
form :action => action, :method => "post" do
label label_text; br
select :name => field_name do
option_list.each do |value, text|
option(text || value, :value => value)
end
end
input :type => "submit", :value => button_text
end
end
Your example above would look something like:
options = [ ["marvin", "Marvin the paranoid Android"],
["arthur", "Arthur Dent"], ... ]
select_form(R(MyController), "Select a hitchhiker:", "character",
options)
It should also be easy to extract just the <select> portion. In fact
I think I'll do that on my end too...
