JS, Prototype - Search DOM Elements

Question

I can't figure out how to sort through collections. The $$ selector (". First input") returns a set:

[<input type="checkbox" id="id-9" name="ids[]" value="9">, <input type="checkbox" id="id-23" name="ids[]" value="23">, <input type="checkbox" id="id-24" name="ids[]" value="24">, <input type="checkbox" id="id-27" name="ids[]" value="27">, <input type="checkbox" id="id-1" name="ids[]" value="1">]

I check the marked elements, if checked, then put its id in the array:

 var checkedElemets = []; var elements = $$(".first input"); for(var i in elements){ if(elements[i].getValue('checked') != null){ checkedElemets.push(elements[i].getValue('checked')); } }

The browser swears that there is no getValue method in the elements [i] object. Please help me understand my mistakes.

Moreover, the construction elements [i] .getValue ('checked') where i is the ordinal number of the element, in the console works fine:> elements [0]. GetValue ('checked') returns> "9"

It is necessary to get the value of the element also added to the array
If elements [i] is a DOM node, then elements[i].значение returns an attribute with the name значение .
For example: elements[i].value returns the value attribute.
