    The javascript:pageObj.sendPage('21'); is a url which you can navigate to. The web-browser doesn't actually navigate to the script, instead it executes the script. So you can simply use Navigate method of WebBrowserControl:

    this.webBrowser1.Navigate("javascript:pageObj.sendPage('21');");

    is the most direct way of calling JavaScript from C/C++. It effectively runs the code using eval() which is a JavaScript function that evaluates code represented as a string.

    A detailed tutorial for embedding JS in C++ via Mozilla's SpiderMonkey engine can be found here Basically you need to include jsapi.h, create/configure/cleanup the JS engine as the tutorial describes (populating the char* script with your string literal JS source code and passing the resulting character array to JS_EvaluateScript), and then link against the SpiderMonkey library when you build

    You can't. Javascript runs client side, C# runs server side. In fact, your server will run all the C# code, generating Javascript. The Javascript then, is run in the browser. As said in the comments, the compiler doesn't know Javascript. To call the functionality on your server, you'll have to use techniques such as AJAX, as said in the other answers.

    How do we call the function from Javascript? Luckily it’s pretty straight forward as you can see from the code below: Module.onRuntimeInitialized = _ => { const factorialCpp = Module.cwrap('factorial', 'number', ['number']); factorialCpp(10); };

    Invoking a JavaScript Function. The code inside a function is not executed when the function is defined. The code inside a function is executed when the function is invoked. It is common to use the term "call a function" instead of "invoke a function". It is also common to say "call upon a function", "start a function", or "execute a function".
