Dealing with various DOM elements in Rails is proving to be a pain. Although the helpers that Rails provides are certainly useful, they start to fall down whenever I want to do advanced configuration. What I *really* want is to have each DOM object represented by a Ruby class. Here's my theoretical syntax:
require "html/dom"
include HTML
select = DOM::Select.new{ |s|
s.id = "foo"
s.selected = 2
s.options = ["matz", "guido", "larry"]
s.onChange = "location = " + s.options[s.selectedIndex]
}
Let's assume each DOM object has a .html method that generates the raw html. In theory then, select.html would magically generate the following:
<select id='foo' onChange="location = this.options[this.selectedIndex].value;">
<option value="matz">matz
<option value="guido">guido
<option value="larry" selected>larry
</select>
To assign different values, you would replace the value pased to s.options with a hash:
...
s.options = {1=>"matz", 2=>"guido", 3=>"larry"}
...
<option value='1'>matz
<option value='2'>guido
<option value='3' selected>larry
...
What isn't immediately clear to me is how to properly handle this and document. Maybe someone smarter than me could work this out. :)
