如何让一个单选按钮选择另一个单选按钮的值

<button type='button' onclick='selectAs0()'>Select All As 0</button>

<input type='radio' name='setA' value='0' /> 0
<input type='radio' name='setA' value='1' /> 1

<input type='radio' name='setB' value='0' /> 0
<input type='radio' name='setB' value='1' /> 1

function selectAs0() {
  var ALL = document.getElementsByTagName("INPUT");

  for(var x = 0; x< ALL.length;x++) {
    if(ALL[x].type=='radio' && ALL[x].value == 0) {
      ALL[x].checked = true;
    }
  }
}

<input type='radio' onclick='selectAs0()' />
