easy ui 删除多行操作

    function questionChange(){
            var row3 = $dg3.edatagrid(‘getSelected‘);//当前选择行
            var editrow3 = $dg3.edatagrid(‘getRowIndex‘, row3);//当前选择行的索引号
            var correlate_seq3 = row3.correlate_seq;//问题编号
            var rows = $dg4.datagrid(‘getRows‘);
             for(var i = 0;i<=rows.length;i++){
                var correlate_seq = rows[i].correlate_seq;
                var editrow = $dg4.edatagrid(‘getRowIndex‘, rows[i]);
                if(correlate_seq == correlate_seq3){
                        $dg4.datagrid(‘beginEdit‘, editrow);
                        $dg4.datagrid(‘deleteRow‘,editrow);
