　点击获取所有的子节点

var setting = {
    data: {
        simpleData: {

        }
    },
    callback: {
        onClick: treenodeClick

function treenodeClick(event, treeId, treeNode, clickFlag) {
    //此处treeNode 为当前节点
     var str ='' ;
     str = getAllChildrenNodes(treeNode,str);
     alert(str); //所有叶子节点ID
}
 
function getAllChildrenNodes(treeNode,result){
      if (treeNode.isParent) {
        var childrenNodes = treeNode.children;
        if (childrenNodes) {
            for (var i = 0; i < childrenNodes.length; i++) {
                result += ',' + childrenNodes[i].id;
