Extjs4实现两个GridPanel之间数据拖拽功能具体方法

1、之前在winForm上有看过在选择数据时会将一些数据放在待选框中，而用户可以将想要选择的数据放到备选框中，那么如何用Extjs实现类似功能，我们选择用两个gridPanel来模拟其中的备选框和待选框。如下图所示：

定义代码如下：

         {
               xtype:'gridpanel',
               multiSelect: true,
                id:'staff', 
                x: 5,
             y: 0,
             height: 205,
             width: 260,
                viewConfig: {  
                    plugins: {  
                         ptype: 'gridviewdragdrop',  
                         dragGroup: 'firstGridDDGroup',  
                       dropGroup: 'secondGridDDGroup'  
               },
               listeners: {  
                  drop: function(node, data, dropRec, dropPosition) {  
                      var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('name') : ' on empty view';
                  }  
               }  
           },
            store:StaffData, //加载数据的store 
            columns: columns,  
            stripeRows: true,  
            title: '从业人员',  
            margins: '0 2 0 0'  
            },
           {
            xtype:'gridpanel',
            id:'admin',
            x: 280,
           y: 0,
           height: 205,
           width: 260,
          viewConfig: {  
              plugins: {  
                  ptype: 'gridviewdragdrop',  
                  dragGroup: 'secondGridDDGroup',  
                  dropGroup: 'firstGridDDGroup'  
              },  
              listeners: {  
                  drop: function(node, data, dropRec, dropPosition) {  
                      var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('name') : ' on empty view'; 
                  }  
              }  
          },  
          store:AdminData,  
          columns:columns,  
          stripeRows:true,  
          title:'管理员',  
          margins:'0 0 0 3'
           }

这样我们在拖拽时即可以将数据存储在所对应的store中，需要的时候从store取出数据即可。
