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);
 }
 }
}
