Ext 表格得到所有行，并得到相应的列值
//取出被所有列值 function getGridValue(gridname){ var grid = Ext.getCmp(gridname); var grid_data = grid.getStore(); //var data_ids = ""; var data_values = ""; for(var i= 0 ;i< grid_data.data.length;i++){ var row = grid_data.getAt(i); var id = row.get("class_unid"); var year = row.get("score"); if(year == "") year = "null"; data_values += ";"+id+","+year; } data_values = data_values.substring(1); return data_values; } ?
