Javascript 未捕获的DomeException:未能执行'；removeChild'；在'；节点'；

无法在“节点”上执行“removeChild”：要删除的节点为 不是此节点的子节点

当我执行下面的代码时，我得到了错误。有没有办法解决这个问题

function clickLinks(links) {
  for(var item in links) {
      var anchor = document.createElement("a");

      anchor.target = "_blank";
      anchor.href   = links[item];

      document.body.appendChild(anchor);
      window.setTimeout(function() {
        anchor.dispatchEvent(new MouseEvent("click",{
              "bubbles"    : true,
              "cancelable" : true,
              "view"       : window
          }));


          window.setTimeout(function() {
              document.body.removeChild(anchor);
          }, 50);
      }, 50);
    }
   }

您需要为正在使用的锚点变量创建一个闭包，以确保它不会在for循环的下一次迭代中被覆盖

function clickLinks(links) {
 for(var item in links) {
  var anchor = document.createElement("a");

  anchor.target = "_blank";
  anchor.href   = links[item];

  document.body.appendChild(anchor);
  (function iifeclosure(anchor){
  window.setTimeout(function() {
    anchor.dispatchEvent(new MouseEvent("click",{
          "bubbles"    : true,
          "cancelable" : true,
          "view"       : window
      }));


      window.setTimeout(function() {
          document.body.removeChild(anchor);
      }, 50);
  }, 50);
  })(anchor);
 }
}
