鉴于 Windows 8 中 Javascript 的兴起,Windows 8 / .Net 4.5 / VS 2012 是否提供了一种机制,可以在应用程序中嵌入 Chakra javascript 引擎以启用脚本编写?如果是这样,是否有相关文档?

Given the rise of Javascript in Windows 8, does Windows 8 / .Net 4.5 / VS 2012 provide a mechanism to embed the Chakra javascript engine in application to enable scripting? If so, is there documentation for this somewhere?

目前尚无已发布或讨论过的机制可以执行此操作。目前,它仅适用于 IE 和 Metro 风格应用程序。甚至没有 Windows Scripting Host 风格的公开。

您希望在脚本中体现 Chakra 的哪些内容?

There is no mechanism to do this that has been released or talked about. For now, it is available only in IE and to Metro style apps. There isn't even a Windows Scripting Host style exposure of it.

What is it about Chakra that you want in your scripting?

IE ActiveX 不使用与独立 IE 相同的 JavaScript 引擎吗?

您可以简单地嵌入 Internet Explorer ActiveX 框架并将其隐藏。

Doesn't IE ActiveX use the same JavaScript engine as IE standalone?

You can simply embed Internet Explorer ActiveX frame and keep it hidden.

是的,存在。

请参阅:https://github.com/Microsoft/ChakraCore/wiki/Embedding-ChakraCore< /a>

 using System;
 using System.Runtime.InteropServices;
 using ChakraHost.Hosting;

public class HelloWorld
{
    static void Main() {
    JavaScriptRuntime runtime;
    JavaScriptContext context;
    JavaScriptSourceContext currentSourceContext = JavaScriptSourceContext.FromIntPtr(IntPtr.Zero);
    JavaScriptValue result;

    // Your script, try replace the basic hello world with something else
    string script = "(()=>{return \'Hello world!\';})()";

    // Create a runtime. 
    Native.JsCreateRuntime(JavaScriptRuntimeAttributes.None, null, out runtime);

    // Create an execution context. 
    Native.JsCreateContext(runtime, out context);

    // Now set the execution context as being the current one on this thread.
    Native.JsSetCurrentContext(context);

    // Run the script.
    Native.JsRunScript(script, currentSourceContext++, "", out result);

    // Convert your script result to String in JavaScript; redundant if your script returns a String
    JavaScriptValue resultJSString;
    Native.JsConvertValueToString(result, out resultJSString);

    // Project script result in JS back to C#.
    IntPtr resultPtr;
    UIntPtr stringLength;
    Native.JsStringToPointer(resultJSString, out resultPtr, out stringLength);

    string resultString = Marshal.PtrToStringUni(resultPtr);
    Console.WriteLine(resultString);
    Console.ReadLine();

    // Dispose runtime
    Native.JsSetCurrentContext(JavaScriptContext.Invalid);
    Native.JsDisposeRuntime(runtime);
}

}

Yes, exists.

See: https://github.com/Microsoft/ChakraCore/wiki/Embedding-ChakraCore

 using System;
 using System.Runtime.InteropServices;
 using ChakraHost.Hosting;

public class HelloWorld
{
    static void Main() {
    JavaScriptRuntime runtime;
    JavaScriptContext context;
    JavaScriptSourceContext currentSourceContext = JavaScriptSourceContext.FromIntPtr(IntPtr.Zero);
    JavaScriptValue result;

    // Your script, try replace the basic hello world with something else
    string script = "(()=>{return \'Hello world!\';})()";

    // Create a runtime. 
    Native.JsCreateRuntime(JavaScriptRuntimeAttributes.None, null, out runtime);

    // Create an execution context. 
    Native.JsCreateContext(runtime, out context);

    // Now set the execution context as being the current one on this thread.
    Native.JsSetCurrentContext(context);

    // Run the script.
    Native.JsRunScript(script, currentSourceContext++, "", out result);

    // Convert your script result to String in JavaScript; redundant if your script returns a String
    JavaScriptValue resultJSString;
    Native.JsConvertValueToString(result, out resultJSString);

    // Project script result in JS back to C#.
    IntPtr resultPtr;
    UIntPtr stringLength;
    Native.JsStringToPointer(resultJSString, out resultPtr, out stringLength);

    string resultString = Marshal.PtrToStringUni(resultPtr);
    Console.WriteLine(resultString);
    Console.ReadLine();

    // Dispose runtime
    Native.JsSetCurrentContext(JavaScriptContext.Invalid);
    Native.JsDisposeRuntime(runtime);
}

}
