遞歸查找父級節(jié)點 的實現(xiàn)：

			//取節(jié)點，得id、pid
			//比對頂級list，遍歷，定義為n
			//若pid=n.id，則n.children=[{parentId:pid}],結(jié)束
			//若pid!=n.id，繼續(xù) goto X
			//X: 查父節(jié)點1，得id1、pid1
			//查父節(jié)點1.children=[{parentId:id1}]
			//比對頂級list，遍歷，定義為n,
			//若pid1=n.id，則n.children=[{parentId:若pid1}],
			// 		同時遍歷：n.children，定義為c,當(dāng)c.id=查父節(jié)點1.id, 則c=查父節(jié)點1
			// 			結(jié)束
			//若pid1!=n.id,繼續(xù) goto X
