Prototype: find all elements with a certain class?

Question

Using the Prototype js framework, how do you find all elements with a certain class?

Solution 1

You can use the $$ function to get elements by class:

$$(".myclass")

Will give you an array of elements you can iterate over. This function allows you to use any css selector to get the elements, too:

$$("li.myclass")
$$("p#test")

$$ lets you pass in any css selector.

$$('.class')

For any who come across this in the future: it looks like this function is available in PrototypeJS 1.5+. If I'm wrong about this, someone please correct me.
