Answered question

When you record your application with NeoLoad, all requests/responses exchanged between the browser and your server are recorded. Since NeoLoad replays a script at protocol level, none of the Javascript that was recorded is executed.

Most of the time this Javascript is only needed to render the UI and so there's no need to evaluate since NeoLoad works at the protocol level. However, if you need to evaluate a Javascript sent by your server in your script, it's still possible.

Let's say you are able to extract your function from a server response. Here it is:

function AC_AddExtension(src, ext) 

{   if (src.indexOf('?') != -1)     

  return src.replace(/\?/, ext+'?');

  else

  return src + ext;

}

That function has two parameters.

You can use the NeoLoad Javascript below to evaluate that function:

//I put the content of my variable extractor inside jsfunctionDef variable

var jsfunctionDef = context.variableManager.getValue("jscontent");

//I use a NeoLoad variable to create a random string

var nlRandom = context.variableManager.getValue("StringRandomVariable_0");

//Here i evaluate my function

eval(jsfunctionDef);

// Use the js function with parameters and get result

var result = AC_AddExtension(nlRandom, "hardvalue");

//We log the result in Load Generator logs.

logger.debug("JS Value="+result);

This is just an example that you can adapt to suit your needs.
