*清空選中的第一個節(jié)點的子節(jié)點

functionremoveChildNodesTree()

vartreeObj=$.fn.zTree.getZTreeObj("baseTree");

//獲取全部節(jié)點數(shù)據(jù)

varnodes=treeObj.getNodes();

for(vari=0,l=nodes.length;ii++)

//清空選中的第一個節(jié)點的子節(jié)點

treeObj.removeChildNodes(nodes[i]);

//--

/script

div

div

ulid="baseTree"/ul

inputtype="button"id="btn"value="清空選中的第一個節(jié)點的子節(jié)點"/
