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;

    }
