c# - 弹出窗口拦截器验证

Question

如何检查客户端浏览器是否通过 C# 打开了弹出窗口阻止程序？

我尝试打开这样的弹出窗口

ClientScript.RegisterStartupScript(this.GetType(), "newWindow", String.Format("<script>window.open('{0}', 'Cliente', 'toolbar=no,directories=no,status=no,menubar=no, scrollbars=yes,resizable=no', '720', '600', 'true'); </script>", url));

但是如果浏览器有弹出窗口阻止程序，我需要打开警报

我怎样才能做到这一点？

你可以这样做:

ClientScript.RegisterStartupScript(this.GetType(), "newWindow", String.Format("<script>var myPopup = window.open('{0}', 'Cliente','toolbar=no,directories=no,status=no,menubar=no, scrollbars=yes,resizable=no','720', '600', 'true');if(!myPopup)alert('a popup was blocked. please make an exception for this site in your popup blocker and try again');</script>",url));

注意:没有测试是否编译，但大致思路是这样的。

编辑-添加测试:

string mys="<script>var myPopup = window.open('{0}', 'Cliente','toolbar=no,directories=no,status=no,menubar=no, scrollbars=yes,resizable=no','720', '600', 'true');if(!myPopup)alert('a popup was blocked. please make an exception for this site in your popup blocker and try again');</script>";

Console.WriteLine(string.Format(mys,"page.aspx"));

产品:

<script>var myPopup = window.open('page.aspx', 'Cliente','toolbar=no,directories=no,status=no,menubar=no, scrollbars=yes,resizable=no','720', '600', 'true');if(!myPopup)alert('a popup was blocked. please make an exception for this site in your popup blocker and try again');</script>

我不认为这有什么问题。现在，我的建议是您删除 <script></script>标签并让 RegisterStarupScript 通过传递 true 添加它们作为最后一个参数，如下所示:

ClientScript.RegisterStartupScript(this.GetType(), "newWindow", String.Format("var myPopup = window.open('{0}', 'Cliente','toolbar=no,directories=no,status=no,menubar=no, scrollbars=yes,resizable=no','720', '600', 'true');if(!myPopup)alert('a popup was blocked. please make an exception for this site in your popup blocker and try again');",url),true);
