原生JavaScript实现remove()和recover()功能示例

function remove(selectors) {
  selectors.removeNode = [];
  if (selectors.length != undefined) {
    var len = selectors.length;
    for (var i = 0; i < len; i++) {
      selectors.removeNode.push({
        parent: selectors[i].parentNode,
        inner: selectors[i].outerHTML,
        next: selectors[i].nextSibling
      });
    }
    for (var i = 0; i < len; i++)
      selectors[0].parentNode.removeChild(selectors[0]);
  }
  else {
    selectors.removeNode.push({
      parent: selectors.parentNode,
      inner: selectors.outerHTML,
      next: selectors.nextSibling
    });
    selectors.parentNode.removeChild(selectors);
  }
}
function recover(selectors) {
  var len = selectors.removeNode.length;
  for (var i = 0; i < len; i++) {
    var node = selectors.removeNode[i];
    if (node.next == null)
      node.parent.innerHTML += node.inner;
    else {
      var div = document.createElement("div");
      div.innerHTML = node.inner;
      node.parent.insertBefore(div.childNodes[0], node.next);
    }
  }
}
