jQuery syntax for radio button

In an attempt to abbreviate code and perhaps make it run a touch faster, I tried this code for getting the value if an input whose name is key is a radio button:

var elem = $(':input[name^="'+key+'"]');
currVal = (elem.prop('type') == 'radio' ? 
  ':input[name^="'+key+'"]:checked').val() : elem.val());

I've tried various ways to abbreviate the instruction

':input[name^="'+key+'"]:checked')

but nothing works.

Is there a way of using elem in this situation?

Here's a working fiddle using your code: https://jsfiddle.net/wvbxmgpe/

var elem = $(':input[name^="'+key+'"]'),
currVal = elem.prop('type') == 'radio'
  ? $(':input[name^="'+key+'"]:checked').val()
  : elem.val();

Well you already have the element with 

var elem = $(':input[name^="'+key+'"]');

So instead of looking up all the elements again, use filter

elem.filter(":checked").val()

My guess is $("input[name='+key+'][type='radio']:checked").val(); should work for you.
