1、childNodes 获取子节点

childNodes: function(node) {
            return isStartComment(node) ? getVirtualChildren(node) : node.childNodes;
        }

 

2、emptyNode 清空子节点

emptyNode: function(node) {
            if (!isStartComment(node))// 如果非ko开始节点
                ko.utils.emptyDomNode(node);
            else {
                var virtualChildren = ko.virtualElements.childNodes(node);
                for (var i = 0, j = virtualChildren.length; i < j; i++)
                    ko.removeNode(virtualChildren[i]);
            }
        }
