ztree获取勾选节点数据并且与表单信息合并

$('#save').click(function () {
        var nodes = zTree.getCheckedNodes(true);   //获取被勾选/未勾选的节点集合
        // console.log(nodes);
        var id;    //存放节点id
        var nodestring="";   //拼接节点的id为一个字符串      
        var Sendjson={};
        var resultjson;
        for(var i=0;i<nodes.length;i++) {
            id=nodes[i].id;
            idarry[i]=id;
            if(i<nodes.length-1) {
                nodestring += id + ',';
            }
            else
                nodestring+=id;
        }
        Sendjson.data=nodestring;
        var form = $('#Addmessge').serializeJSON();//表单信息
        resultjson=Object.assign(Sendjson,form)    //合并两个对象
        console.log(JSON.stringify(resultjson));

    });

data为节点id，即已经勾选的id值，后面为一个表单的信息
{"data":"1,11,111,1111,1112","Cname":"","Cencoding":"","Sequence":"","Ucategory":"test1","Rdetial":"test1","Ninformation":""}
