Question

我有一个网格和网格上下文菜单我调用一个函数如下 -

在网格上下文菜单中，我添加了以下项目

{ text: 'Preview', handler: 'PreviewGrid', scope: cnt, };

在控制器中 -

previewGrid: function (contextMenuItem) {    
        // Here I am getting the item i.e. contextmenu item.
        // But I want here is grid on which there was right click
}

我尝试使用item.ownerCt.up('grid')

但它不起作用。

任何帮助将不胜感激。

        var contextMenu = Ext.create('Ext.menu.Menu', {
            width: 200,
            items: [{
                text: 'Preview',

                    var record = grid ? grid.getSelection()[0] : null;
                    if (!record) {
                        return;
                    }

                    alert(record.get('name'));
                }
            }]
        });

        grid.on("itemcontextmenu", function(grid, record, item, index, e) {
            e.stopEvent();
            contextMenu.showAt(e.getXY());
        });
    }
});

这适合我。

在网格听众中：

listeners: {

  itemcontextmenu: function (grid, record, item, index, e) {

     var contextMenu = Ext.create('Ext.menu.Menu', {
         height: 200,
         width: 250,
         items: [{
                text:'Preview', 
                handler: function () {
                    //code...
                }
         }]
     });
    e.stopEvent();
    contextMenu.showAt(e.getXY());
  }
}
