Question

Specifically I need the equivalent selector for this, which worked in Prototype 1.5.0:

//for each element with class of 'myClassName' and an ancestor with id='myElementID'...
document.getElementsByClassName('myClassName', $('myElementID')).each( ... );

I tried this:

$$('myElementID input.myClassName').each( ... ); //Because I will be selecting input elements with this class

and this:

$$('myElementID .myClassName').each( ... ); //Trying to get all child elements with this class name

I get an empty list every time. The child elements I want are not necessarily direct children, so I know the > character will not work.

I don’t use Prototype and can’t find help on this exact issue. Any help is appreciated.

Answer 1

The $$ function will take any CSS Selector, so use a # to get myElementID by id. The rest of the selector to get all the inputs with class myClassName inside of myElementID was correct.

$$('#myElementID input.myClassName').each( ... );
