//不是很确切地说 应该用GridPanel替代ColumnModel吧 要不然光写这句就要报错了var cm = new Ext.grid.GridPanel([ {header:'曲目编号', dataIndex:'music_id'}, {header:'曲目名称', dataIndex:'music_name'}, {header:'作曲家', dataIndex:'composer'}, {header:'演奏乐器', dataIndex:'instrument'}]); -
当年话下
首先确保你的js文件的引用路径是否正确，第二，store.load();改为store.load(data);
