浅谈原生JavaScript实现remove()和recover()

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。

 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);
         }
     }
 }
