Question

ztree判断所有节点是否选中状态

Answer 1

获取 zTree 当前被选中的节点数据集合
var treeObj = $.fn.zTree.getZTreeObj("tree");
var nodes = treeObj.getSelectedNodes();
获取 zTree 的全部节点数据
var treeObj = $.fn.zTree.getZTreeObj("tree");
var nodes = treeObj.getNodes();

for(var node in nodes){
//判断节点是否选中

var checked = node.checked;

if(checked){
alert("该节点处于选中状态");

}else{
alert("该节点未选中");
}
}
