Get text of label sibling of checked checked using javascript

I want to be able to check if the input is checked and if it is checked then grab the data associated with that input and display it into another div. here is my code.

var levels = $('input:checked + label').map(function() {
  return $(this).text();
}).get();
//alert(levels);
document.getElementById('listprice').innerHTML = levels;
