Answer 4

用ajax中的ModalPopupExtender控件弹出一个panel

Answer 5

可用ajax的ModalPopupExtender控件弹出一个panel

Answer 6

没仔细看 
你那没有弹出窗口的原因是因为后面有个Redirect(),而导致前面的Alert覆盖掉了
所以你应该在JS里面实现跳转 比如4楼.

Answer 7

也就是说 你试下4楼的代码 但是你得把你后面的Redirect去掉（location.href实现页面跳转）.

                        </td>
后台弹窗方法mpePassword.Show();

Answer 9

还有就是直接使用Response.Write() 会在页面的第一行写入JS代码 带来的问题就是 有时候会导致浏览器的兼容问题 最好的是使用pg.ClientScript.RegisterStartupScript() 这种来注册JS事件.

Answer 10

.modalBackground
        {
            position: absolute;
            z-index: 100;
            top: 0px;
            left: 0px;
            background-color: #000;
            filter: alpha(opacity=60);
            -moz-opacity: 0.6;
            opacity: 0.6;
        }
        .panel
        {
            background-color: White;
            height: 300px;
            width: 500px;
        }

Answer 11

试了一下 不行  我在贴点代码
 bool success = true;
        success = UpdateMachineIp(1, txtIp1.Text.Trim());
        success = UpdateMachineIp(2, txtIp2.Text.Trim()) && success;
        success = UpdateMachineIp(3, txtIp3.Text.Trim()) && success;
        success = UpdateMachineIp(4, txtIp4.Text.Trim()) && success;
        success = UpdateMachineIp(5, txtIp5.Text.Trim()) && success;
        success = UpdateMachineIp(6, txtIp6.Text.Trim()) && success;        if (success)
        {
            //msg.Text = "保存成功！";
            Response.Write("<script>alert('成功！'),location.href='QdMachine.aspx';</script>");
        }
        else
        {
            msg.Text = "保存失败！";
        }

Answer 12

 Response.Write("<script language='javascript'>alert('保存成功！');window.location.href='QdMachine.aspx';</script>");

Answer 13

是不是前台xml里面要设置什么  为什么我总是跳不出来

Answer 14

是不是跑到false里面去拉?

Answer 15

如果success是true  那么跳出  保存成功
如果success是false 那么跳出  保存失败

Answer 16

我怎么看见你好多马甲啊
不就是提示跳转嘛  if (success)
        {
            msg.Text= "保存成功！";//此处替换成弹窗，但是用了很多方法不能成功，求解
        }
        else
        {
            msg.Text= "保存失败！";
        }
        Thread.Sleep(2000); 
        this.Response.Redirect("QdMachine.aspx");
=================》if (success)
{
      ClientScript.RegisterClientScriptBlock(GetType(), "", "<script>alert(保存成功!');setTimeout(function(){location.href=QdMachine.aspx'},2000);</script>");
}
else
{
      ClientScript.RegisterClientScriptBlock(GetType(), "", "<script>alert(保存失败!');</script>");
      return;
}

Answer 17

有兔斯基揉头的表情么，我想揉一通，不能实现哎。
在html里面要写什么么？还是什么 崩溃ing

Answer 18

看看结果再说

        }
        else
        {
            Response.Write("<script language='javascript'>alert('保存失败！');</script>");
        }

Answer 19

页面没有啥 问题 关键你的代码 是什么狗屁代码
bool success = true;
success = UpdateMachineIp(1, txtIp1.Text.Trim());
success = UpdateMachineIp(2, txtIp2.Text.Trim()) && success;
success = UpdateMachineIp(3, txtIp3.Text.Trim()) && success;
success = UpdateMachineIp(4, txtIp4.Text.Trim()) && success;
success = UpdateMachineIp(5, txtIp5.Text.Trim()) && success;
success = UpdateMachineIp(6, txtIp6.Text.Trim()) && success;

Answer 20

这是一个IP的check，最后success肯定是true，后面不出现弹窗

Answer 21

关于AJAX中调用JS问题，请参考我的博客文章：
在UpdatePanel中调用JS，弹出页面将其中的JS代码换成：<script>alert('成功！'),location.href='QdMachine.aspx';</script>

Answer 22

算了 直接写给你吧：string script = "<script language='javascript'>alert("+msg+");</script>";  
     ScriptManager.RegisterStartupScript(grvWorkList, this.GetType(), "alert", script, false);  

Answer 23

 this.ClientScript.RegisterClientScriptBlock(this.GetType(), "message", "<script>alert('成功！')</script>");
