Forum: Rails Spinoffs (closed, excessive spam) Class property

I have a DIV in the following format: <div class="MyClass[Param]">

I want to parse it. Which approach is better? I can found all divs
with $$('.MyClass'), but how to find [Param] string?

Or, for me, it's better to use <div class="MyClass" id="Param"> and
then found all $$('.MyClass').each(function(el) { el.id })?

I think, the first method is better, than second one. But I don't know
how to implement it with Prototype.

Thank you.

Not sure if [] is valid in a css class.  Why not use two classes?

<div class="MyClass Param">

$$('.MyClass.Param')

or

$$('.MyClass.' + someParam)

$$('[class="MyClass[Param]"]') should work.
Multiple classes is not a bad idea, just remember that IE ignores such
css declarations (and applies only last class' rules)

Param is a non constant value ;-)

For example, <div class="MyClass[4342]"> I want to extract: Element
(div), class name ("MyClass") and params ("4342"). So on.

If the value of param is unique to an element, I'd move it to the id 
attribute.

For a precise matching:

$$('div').findAll(function(el) {
  return /^MyClass\[\d{1,4}\]$/.test(el.className);
})

Though such approach does indeed seem weird.

Thanks a lot ;-) That's what I want ;-) Thanks ;-)
