style.display =“boxed”;不工作

Question

单击时尝试在不同的位置显示不同的图像，这是一个设置为10毫秒的间隔，当值改变时，它应该切换div，一个是无，一个是盒装。

function test() {
  var x = document.getElementById('spc_02');
  var y = document.getElementById('purchase_01');
  if (rest === 0) {
    x.style.display = "none";
    y.style.display = "boxed";
  }
  if (rest === 1) {
    x.style.display = "boxed";
    y.style.display = "none";
  }
  var x = document.getElementById('spc_03');
  var y = document.getElementById('purchase_02');
  if (news === 0) {
    x.style.display = "none";
    y.style.display = "boxed";
  } if (news === 1) {
     x.style.display = "boxed";
     y.style.display = "none";
  }
 }
