js 查找树节点 数组去重

//查找树节点
function findData(curOrg, id) {
     var array = [];
     if ((typeof curOrg == 'object') && (curOrg.constructor == Object.prototype.constructor)) {
       array.push(curOrg);
     }
     else array = curOrg;
     for (var i = 0; i < array.length; i++) {
       var jn = array[i];
       if (jn.OrgId == id) {
         return jn;
       }
       if (jn.Orgs != "") {
         return findData(jn.Orgs, id);
       }
     }
   }

//数组去重
   function unique(arr) {
     var result = [], hash = {};
     for (var i = 0, elem; (elem = arr[i]) != null; i++) {
       if (!hash[elem]) {
         result.push(elem);
         hash[elem] = true;
        }
      }
     return result;
    }
