easyui树节点拖拽排序的存储过程

easyui树的拖拽排序功能

easyui树中有拖拽功能

树结构如下:

一个行政区域对应一个单位,一个单位对应多个部门,每个部门下有相关人员,功能要求:

(1)行政区域没有子节点,点击text加载部门;(2)点击部门的text,如果有下级部门则加载部门,没有则加载人员;(3)树都有拖拽排序功能

1、前台页面:


    var $orgs_tree = $("#orgs_tree").tree(orgs_tree_default);

    var orgs_tree_default = {
    			url : 'servlet/SearchServlet?dispatch=0',
    			animate : true,
    			onClick:function(node){
    				var url = "servlet/SearchServlet?dispatch=1";//默认加载地区的树
    				var isDeptTree = false;
    				var unit_id ;
    				//根据行政区划获取单位列表
    				$.getJSON(url,{regions_id:node.attributes.regions_id},function(data){					
    					if(data.length > 1){
    						
    					}else if(data.length == 0){
    						
    					}else{						
    					//点击部门树的text,加载树
    					$("#dept_tree").tree({  				       
    					     url:"servlet/SearchServlet?dispatch=2&unit_id=" + unit_id+"&id=0",  //默认加载部门的树
    					     onBeforeExpand:function(node,param){  						    
    					        $("#dept_tree").tree("options").url="servlet/SearchServlet?dispatch=2&unit_id=" + unit_id+"&id="+node.id; 
    					      },  
    					      onSelect:function(node){	//当点击text的时候,展开子节点
    					         $(this).tree("expand",node.target);  
    					      }
    					    });  	
    					}
    				});
    			},
    			onDrop:function(target, source, point){ //行政区域树的拖拽功能
    				var node = $("#orgs_tree").tree("getNode",target); // 将DOM对象转换为node				
    				//组装参数
    				var param = {						
    						//目标节点属性
    						targetId : node.attributes.regions_id ,
    						targetSort : node.attributes.regions_sort ,
    						
    						//源节点属性
    						sourceId : source.attributes.regions_id , 
    						sourceSort : source.attributes.regions_sort,
    						
    						//操作方式3种,append:变更父节点,top:平级-上 bottom:平级-下
    						point : point};
    				
    				//更新数据库,这个后台需要用到存储过程
    				var url = "servlet/ManagerServlet?dispatch=0";
    				$.post(url,param,function(data){
    					alert("success");
    				});				
    			}
    };
    2、java后台调用方法
    public String dragRegionsSort(int target_id, int target_sort,
    			int source_id, int source_sort,String operation) {
    		String result = "排序成功";
    		conn= this.getConnection();
    		CallableStatement statement = conn.prepareCall("{call PRO_UPDATE_REGION_SORT(?,?,?,?,?)}");
    		try {
    			statement.setInt(1, target_id);
    			statement.setInt(2, target_sort);
    			statement.setInt(3, source_id);
    			statement.setInt(4, source_sort);
    			statement.setString(5, operation);
    			statement.execute();	
    		} catch (SQLException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    		return result ;
    		
    	}
    3、存储过程
    create or replace procedure "PRO_UPDATE_REGION_SORT"
    (
           target_id in number,--目标id
           target_sort in number,--目标排序号
           source_id in number,     --源id
           source_sort in number , --源排序号
           operation  in varchar2     --操作类型,之前还是之后
    )as
     p_tid   number;
      p_sid  number ; 
    begin
      select regions_id into p_tid from tbl_regions t where t.regions_id = target_id;
      select regions_id into p_sid from tbl_regions t where t.regions_id = source_id;
      dbms_output.put_line('---目标id--'||p_tid||'---源id---'||p_sid);
      if target_sort - source_sort = 1 then 
          if operation = 'top' then
            null;
          else
            update tbl_regions t set t.regions_sort = target_sort WHERE t.regions_id = source_id ;
            update tbl_regions t set t.regions_sort = source_sort WHERE t.regions_id = target_id ;
          end if ;
       elsif target_sort - source_sort = -1 then
          if operation = 'top' then
            update tbl_regions t set t.regions_sort = target_sort WHERE t.regions_id = source_id ;
            update tbl_regions t set t.regions_sort = source_sort WHERE t.regions_id = target_id ;   
          else
            null;
          end if;
        elsif target_sort - source_sort < -1 then
          if operation = 'top' then       
            update tbl_regions t set t.regions_sort = t.regions_sort + 1 where t.regions_sort >= target_sort and t.regions_sort < source_sort;
            update tbl_regions t set t.regions_sort = target_sort where t.regions_id = source_id ;
            dbms_output.put_line('---排序前目标sort--'||target_sort||'---源sort---'||source_sort);
            dbms_output.put_line('---排序后目标sort--'||target_sort||'---源sort---'||source_sort);
          else
            update tbl_regions t set t.regions_sort = t.regions_sort + 1 where t.regions_sort > target_sort and t.regions_sort < source_sort;
            update tbl_regions t set t.regions_sort = target_sort+1 where t.regions_id = source_id ;
          end if ;
        elsif target_sort - source_sort > 1 then
          if operation =  'top' then
            update tbl_regions t set t.regions_sort = t.regions_sort - 1 where t.regions_sort > source_sort and t.regions_sort < target_sort;
            update tbl_regions t set t.regions_sort = target_sort - 1 where t.regions_id = source_id ; 
          else 
            update tbl_regions t set t.regions_sort = t.regions_sort - 1 where t.regions_sort > source_sort and t.regions_sort <= target_sort;
            update tbl_regions t set t.regions_sort = target_sort where t.regions_id = source_id ;
          end if;
        end if;
    end;
