JavaScript 获取所点击行中某单元格的内容

原理：

在行绑定时为行添加onclick handler，并绑定所要显示的单元格内容：

代码如下

    <asp:GridView ID="GridView2" AutoGenerateColumns="False" ShowHeader="True" runat="server"
        OnRowDataBound="GridView1_RowDataBound">
        <Columns>
            <asp:BoundField HeaderText="0" DataField="Col0" />
            <asp:BoundField HeaderText="1" DataField="Col1" />
            <asp:BoundField HeaderText="2" DataField="Col2" />
            <asp:BoundField HeaderText="3" DataField="Col3" />
            <asp:BoundField HeaderText="4" DataField="Col4" />
            <asp:BoundField HeaderText="5" DataField="Col5" />
            <asp:TemplateField HeaderText="6">
                <ItemTemplate>
                    <asp:Button ID="gridButton" Text="Press Me" runat="server"></asp:Button>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField HeaderText="7" DataField="Col7" />
            <asp:BoundField HeaderText="8" DataField="Col8" />
            <asp:BoundField HeaderText="9" DataField="Col9" />
        </Columns>
    </asp:GridView>

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            // The value that we want is in column #9

string valueText = e.Row.Cells[9].Text;

// Find the Button with an ID of "gridButton" (in column #6 of the Grid)

            Button gridButton = (Button)e.Row.Cells[4].FindControl("gridButton");

            if (gridButton != null)
            {
                string clickHandler = string.Format("alert('Value in column #9 is {0}", valueText);
                gridButton.Attributes.Add("onclick", clickHandler);
            }
        }
    }
