利用原生JavaScript实现：
1、remove(selectors)删除指定的一个或一组元素。
2、recover(selectors)恢复刚才删除的元素。
1 function remove(selectors) {
2 selectors.removeNode = [];
3 if (selectors.length != undefined) {
4 var len = selectors.length;
5 for (var i = 0; i < len; i++) {
6 selectors.removeNode.push({
7 parent: selectors[i].parentNode,
8 inner: selectors[i].outerHTML,
9 next: selectors[i].nextSibling
10 });
11 }
12 for (var i = 0; i < len; i++)
13 selectors[0].parentNode.removeChild(selectors[0]);
14 }
15 else {
16 selectors.removeNode.push({
17 parent: selectors.parentNode,
18 inner: selectors.outerHTML,
19 next: selectors.nextSibling
20 });
21 selectors.parentNode.removeChild(selectors);
22 }
23 }
24 function recover(selectors) {
25 var len = selectors.removeNode.length;
26 for (var i = 0; i < len; i++) {
27 var node = selectors.removeNode[i];
28 if (node.next == null)
29 node.parent.innerHTML += node.inner;
30 else {
31 var div = document.createElement("div");
32 div.innerHTML = node.inner;
33 node.parent.insertBefore(div.childNodes[0], node.next);
34 }
35 }
36 }
