方法一:

这是在GridView里面没有控件的情况下,有控件另当别论

var gdview=<%=gridview.ClientID%>;//gridview是GridView控件的ID

或者

var gdview=document.getElementById("<%=gridview.ClientID %>");

//1 读取指定行单元格的值 如果是0则读出其表头的值
//rowIndex=1就是第一行的值
function getCellValueByRow(rowIndex)
{
   for(var i=0;i<gdview.rows(rowIndex).cells.length;i++)
   {
      alert(gdview.rows(rowIndex).cells(i).innerText);//弹出指定行单元格的值

   }
}


//2 读取指定列单元格的值 cellIndex=0则为第一列的值
function getValueByCell(cellIndex)
{
   for(var i=0;i<gdview.rows.length;i++)
   {
       alert(gdview.rows(i).cells(cellIndex).innerText);//指定列单元格的值
   }
}

//3 读取所有单元格的值
function getValueAll(cellIndex)
{
   for(var i=1;i<gdview.rows.length;i++)//要从1开始,从0则会读出表头的值
   {
       for(var j=0;j<gdview.rows(i).cells.length;j++)
       {
           alert(gdview.rows(i).cells(j).innerText);//读取所有单元格的值
        }
   }
}


//4 读取列标头的值
functioin getValueTitle()
{
   for(var i=0;i<gdview.rows(0).cells.length;i++)
   {
      alert(gdview.rows(0).cells(i).innerText);//读取列标头的值

   }
}

方法二:

首先在模板列中添加一个按钮用来选中行，页面有关代码如下：

<asp:GridView ID="gdview" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None"
                                            Height="176px" Width="380px" OnRowDataBound="gdview_RowDataBound" OnSelectedIndexChanging="gdview_SelectedIndexChanging">
                                            <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
                                            <RowStyle BackColor="#E3EAEB" />
                                            <PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
                                            <SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333" />
                                            <HeaderStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
                                            <EditRowStyle BackColor="#7C6F57" />
                                            <AlternatingRowStyle BackColor="White" />
                                            <Columns>
                                                <asp:TemplateField>
                                                    <ItemTemplate>
                                                        <input id="btnLocation" type="button" value="定位到" onclick="Select()" style="height: 20px" />
                                                    </ItemTemplate>
                                                </asp:TemplateField>
                                            </Columns>
                                        </asp:GridView>

脚本代码如下：

//取得gridview中获取选中行指定列的值
      function Select()
      {
            //获取鼠标点击的元素
            var e=event.srcElement;
            //获取元素所在的行的行号（表头行号从0开始）。注意：parentElement只适用于IE浏览器，而parentNode则符合DOM标准。
           //var rowIndex=e.parentElement.parentElement.rowIndex ;
            var rowIndex=e.parentNode.parentNode.rowIndex ;
            //获取GridView控件
            var gdview=document.getElementById("<%=gdview.ClientID %>");
           //分别获取选定行标注点的X、Y坐标
           var value=gdview.rows(rowIndex).cells(列号).innerText;

      }

方法三:

<script type="text/javascript">       function fun()       {           var GridView=document.getElementById("GridView1");           for(var i=1;i <GridView.rows.length;i++)//从1开始，表示不考虑表格列头           {               var html=GridView.rows[i].cells[0].getElementsByTagName("input")[0].value;               alert(html);           }       }     </scr
