    if (tb)
     {
    var rows = tb.rows;
    for (var i = 1; i < rows.length; i++) {
        var id = rows[i].cells[1].innerText;
        var name = rows[i].cells[2].innerHTML;
        var oDropDownList = rows[i].cells[3].childNodes[0];
        var oText = oDropDownList.options[oDropDownList.selectedIndex].text;   //获取GridView中下拉列表中选中的文本
        var oValue = oDropDownList.options[oDropDownList.selectedIndex].value;;   //获取GridView中下拉列表中选中的值   
 }
    }
}

            var rowCount = tb.childNodes[0].childNodes.length;
            for (var i = 1; i < rowCount; i++) {
                var child = tb.childNodes[0].childNodes[i];
                var id = rowCount[i].cells[1].innerHTML;
                var name = child.childNodes[1].innerHTML;
                var oDropDownList = child.childNodes[2].childNodes[0];
                var oText = oDropDownList.options[oDropDownList.selectedIndex].text;
