Perform the operation with intricate inputs

Due to specific requirements, I need to execute a JavaScript function, which is defined in a separate JS file, from a .NET desktop application and retrieve the output.

To achieve this task, I am utilizing Jurassic. However, I am unsure how to invoke functions that require complex data types. Let me illustrate this with an example.

Consider the following function defined in the JS file:

function plus(a, b) {
    return a + b;
}

In order to call this function in .NET, I am using the following code snippet:

Dim auxfile As New Jurassic.FileScriptSource(pathToPreviosJSFile)
Dim aux As New Jurassic.ScriptEngine
aux.Evaluate(auxfile)
Dim suma As Integer = aux.Evaluate("plus(2,3)")

With this implementation, the value of 'suma' would be 5. However, if the definition of the plus function were as follows:

function plus(a, b) {
    return a.value + b.value;
}

How should I modify my call to the plus function to obtain the same result?

Answer №1

When you reference the value property of a and b, it implies that a and b are objects. Therefore, you can invoke the function in this manner:

Dim sum As Integer = aux.Evaluate("plus({value:2},{value:3})")
