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);    }  }}
