返回的是rows数组项是json对象，不是数组，无法通过下标获取，你需要通过dom关系找到第一列的列名称，然后通过rows[i][名称]来获取
　　var colName=$('#tt').parent().find('table.datagrid-htable td:eq(0)').attr('field');//得到第一列的名称
var ids = [];
var rows = $('#tt').datagrid('getSelections');
for(var i=0; i<rows.length; i++){
ids.push(rows[i][colName]);/////
}
alert(ids.join('\n'));本回答被提问者和网友采纳
