  • This should work for you. 

    var myNodeList = document.querySelectorAll("input[value=A], input[value=C]");
for (i = 0; i <	myNodeList.length; i++) {
   	myNodeList[i].checked = true;

    <input type="checkbox" name="name[]" value="A">A</input>
<input type="checkbox" name="name[]" value="C">C</input>
<input type="checkbox" name="name[]" value="D">D</input>
