Hi,

Try below code:


js = "<SCRIPT LANGUAGE=\"JavaScript\">\n";
js += "window.open(\"stampe/frame.aspx?pfid=RULLS\", \"\", \"width=300, height=100\")";
js += "</script>";

Hi, I'm trying to open a new window injecting a javascript in my C# codebehind, actually I've managed to open the new window, but there seems to be a problem with the string that C# turns into JS, because the page is blank and gives me the error &quot;Server error in application &quot;/&quot;.<br />
<br />
Here's the code, it should be simple to sort this out.<br />

<pre><code id="code-8227578">This is the C# code to create the JS string:
js = &quot;&lt;SCRIPT LANGUAGE=\&quot;JavaScript\&quot;&gt;\n&quot;;
js += &quot;window.open(\&quot;/stampe/frame.aspx?pfid=RULLS\&quot;, \&quot;\&quot;, \&quot;width=300, height=100\&quot;)&quot;;
js += &quot;&lt;/script&gt;&quot;;


This is the content of the js variable just before I pass it to Response.Write(js):
&quot;&lt;SCRIPT LANGUAGE=\&quot;JavaScript\&quot;&gt;\nwindow.open(\&quot;/stampe/frame.aspx?pfid=RULLS\&quot;, \&quot;\&quot;, \&quot;width=300, height=100\&quot;)&lt;/script&gt;&quot;</code></pre>

Calling a javascript, syntax problem.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

JScript is Microsoft's dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer. JScript is implemented as an Active Scripting engine, so it can be "plugged in" to OLE Automation applications that support Active Scripting, such as Internet Explorer, Active Server Pages, and Windows Script Host. It also means such applications can use multiple Active Scripting languages, e.g., JScript, VBScript or PerlScript.
