           <asp:Panel runat="server" ID="pnlEtryForm">
              <table>
                 <tr>
                    <td>

                    <td colspan="2">
                       <asp:Button runat="server" ID="btn" Text="test" OnClick="btn_click" />
                    </td>
                 </tr>
              </table>
           </asp:Panel>
           <div id="pnlFormDonate"  runat="server" visible="false">
              <form id="frmDonate" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" >
              <input class="empty" type="hidden" id="bus" name="business" value="[e-mail]">
              <input type="hidden" name="cmd" value="_donations">
              <input type="hidden" name="item_name" value="Donation For IJP">
              <input type="hidden" id="itemNo" name="item_number" value="Donate for IJP Ministry">
              <input type="hidden" name="amount" id="amt">
              <input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_donateCC_LG.gif"
                 border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
              <img alt="" border="0" width="1" height="1" src="https://www.paypal.com/en_US/i/scr/pixel.gif">
              </form>
           </div>
        </ContentTemplate>
     </asp:UpdatePanel>
  </div>
  </form>

上面的"apsx"文件包含一个按钮控件，在按钮单击事件处理程序中，我看到以下代码所示的"div".

the above "apsx" file contains one button control and in the button click event handler i visible the "div" the code below shows.

protected void btn_click(object sender, EventArgs e)
{
     pnlFormDonate.Visible = true;
}

回发后，当我单击贝宝图像链接时，该表单已发布在"Mozilla"中，但是在"Chrome"浏览器中，没有执行任何操作.

请帮我怎么做....

您好兄弟，请使用此代码.

Hello dude use this code.

<form id="form1"  runat="server">
   <div>
     <asp:scriptmanager id="sc" runat="server" xmlns:asp="#unknown">
      </asp:scriptmanager> 
      <asp:updatepanel runat="server" id="uPanel" xmlns:asp="#unknown">

                     </td>
                  </tr>
               </table>



            </asp:panel>


            <div id="pnlFormDonate"  runat="server" visible="false">
            
              <form>
             </form>
           <form id="frmDonate" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
           
               <input class="empty" type="hidden" id="bus" name="business" value="[e-mail]" />
               <input type="hidden" name="cmd" value="_donations" />
               <input type="hidden" name="item_name" value="Donation For IJP" />
               <input type="hidden" id="itemNo" name="item_number" value="Donate for IJP Ministry" />
               <input type="hidden" name="amount" id="amt" />

               <input id="Image1"  runat="server" type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_donateCC_LG.gif">
                  border="0" onclick="Submitfrom()"  name="submit" alt="PayPal - The safer, easier way to pay online!" />
               <img alt="" border="0" width="1" height="1" src="https://www.paypal.com/en_US/i/scr/pixel.gif" />
               </input></form>

   
            </div>
          </contenttemplate>
      </asp:updatepanel> 

     
    
   </div>
   </form>

在单击图像按钮时，您可以调用javascript函数.在该javascript函数中，您只需使用"__doPostBack"即可.请参考以下链接:

http://wiki.asp.net/page.aspx/1082/dopostback-function/ [< ^ ]

这将适用于所有浏览器.因此没有兼容性问题.

Hi,
On click of image button you can call a javascript function. And in that javascript function you just use "__doPostBack". Refer the links below:

http://wiki.asp.net/page.aspx/1082/dopostback-function/[^]

This will work in all the browsers. So no compatibility issue.

--Amit

首先尝试弄清楚不同浏览器如何填充字段.为此使用Fiddler.
我看到的是，您没有确切的动作触发器. Chrome浏览器肯定支持ajax，但这不是问题.但是ASP.NET客户端支持不够广泛.看到这篇文章: http://seejoelprogram.wordpress.com/2008 /09/04/adding-google-chrome-to-aspnet-ajax/ [ http://www.asp.net/web-forms/tutorials/aspnet-ajax/understanding-asp-net-ajax-updatepanel-triggers [

Try first to figure out, how fields are populated by different browsers. Use Fiddler for that.
What I see, that you have no exact action trigger. Chrome is for sure supporting ajax, that won''t be the problem. But ASP.NET client support is not extensive enough. See this article: http://seejoelprogram.wordpress.com/2008/09/04/adding-google-chrome-to-aspnet-ajax/[^]
You can fine-tune the triggering mechanism, see this article: http://www.asp.net/web-forms/tutorials/aspnet-ajax/understanding-asp-net-ajax-updatepanel-triggers[^]
Of course, you can also not relay on built-in triggering and use Javascript as others suggested.
