推荐答案

根据您的代码，您发送一个JavaScript代码来调用一些客户端打印功能，而不是命令ASP.NET引擎重定向到其他页面。这意味着重定向之前的所有代码都是无用的，因为永远不会被执行...

According your code you send a JavaScript code to call some client print function, than order ASP.NET engine to redirect to some other page. It means that all your code before that Redirect is useless as never will be executed...

这与工作方式有关：整个页面被翻译为HTML，这是整个页面完成后发送到客户端（包含嵌入式javascript）。



Response.Redirect是一个中止功能：抛弃所有先前组装的数据并重新启动一个新的空白页面 - 所以你的启动脚本也被扔掉了。



你必须让客户打印，然后重定向完成。

This has to do with how things work: your entire page is "translated" to HTML which is sent up to the client (complete with embedded javascript) when the whole page is complete.

Response.Redirect is an "abort" function: it throws away all previously assembled data and starts again with a new, blank page - so your startup script is thrown away as well.

You have to let the client print, then redirect when he is finished.

你能做的是

what you can do is

function PrintPanel()
{
    // your code....
    //finally after you done with printing call redirect from javascript like below 
    window.location.href("invoice.aspx");
}
