我有一个usercontrol，我想打开一个错误窗口来显示错误消息。我在ascx.cs中使用了window.open，窗口打开正确。 现在我想通过调用另一个方法来关闭打开的窗口，我在使用window.close（）。 这对我不起作用。请帮帮我。 注意：当我使用IE调试器进行调试时，显示'ErrorWindow'未定义 我尝试过： 公共覆盖无效ErrorMessage（） { string url = string.Empty; ClientScriptManager cs = Page.ClientScript; url =ErrorEnhanced.aspx; 输入cstype = this.GetType（）; string script = string.Empty; script =var ErrorWindow = window.open（'+ url +'， 'ErrorWindow'，'width = 400，height = 200，left = 550，top = 180，resizable = no，location = no，toolbars = 0，scrollbars = 0，statusbars = 0，menubar = 0'）。focus（） ;; cs.RegisterStartupScript（cstype，Error_Script，脚本，true）; } public override void CloseErrorWindow（） { ClientScriptManager cs = Page.ClientScr ipt; 类型cstype = this.GetType（）; string script = string.Empty; script =var ErrorWindow; if（ErrorWindow！= null）{; script + =ErrorWindow.close（）;}; cs.RegisterStartupScript（cstype，Error_Script，script ，true）; }

解决方案

你不能关闭用户服务器的窗口。 用java脚本关闭它。使用javascript返回（部分）视图。 只需在这里调用window.close（）。

function openWin（）{ myWindow = window.open（，myWindow，width = 200，height = 100）; //打开一个新窗口} 函数closeWin（）{ myWindow.close（）; //关闭新窗口}

I have a usercontrol where i want to open a error window to display error messages. I have used the window.open in ascx.cs, the window opened correctly. Now i want to close the opened window by calling another method where i am using window.close(). It is not working for me. Please help me on this. Note: when i debugged using IE debugger, It shows 'ErrorWindow' undefined What I have tried: public override void ErrorMessage() { string url = string.Empty; ClientScriptManager cs = Page.ClientScript; url = "ErrorEnhanced.aspx"; Type cstype = this.GetType(); string script = string.Empty; script = "var ErrorWindow = window.open('" + url + "', 'ErrorWindow', 'width=400,height=200,left=550,top=180,resizable=no, location=no,toolbars=0,scrollbars=0,statusbars=0,menubar=0').focus();"; cs.RegisterStartupScript(cstype, "Error_Script", script, true); } public override void CloseErrorWindow() { ClientScriptManager cs = Page.ClientScript; Type cstype = this.GetType(); string script = string.Empty; script = "var ErrorWindow; if(ErrorWindow != null){"; script += "ErrorWindow.close();}"; cs.RegisterStartupScript(cstype, "Error_Script", script, true); }

解决方案

You can't close the window of a user server sided. Close this with java-script. Return a (partial)view with a javascript. Just call window.close() here.

function openWin() { myWindow = window.open("", "myWindow", "width=200, height=100"); // Opens a new window } function closeWin() { myWindow.close(); // Closes the new window }
