Having trouble executing JS function with InjectJS

Help Studio
1

Hello,

I’m building a really simple test case and want to trigger the Javascript function “calculate()” from a simple online calculator (JavaScript Calculator Online). I can do it through the Chrome console and through the buttons but I need to be able to call the function directly.

The most common error I’m getting is “Inject Js Script: ReferenceError: calculate is not defined”.

In my JS file I’ve tested with both:

  • “calculate()”

  • " function trigger(element, input) {
    calculate();
    return “result”;
    }"

Is it even possible to call predefined functions from websites?

Many thanks

I am having a similar problem so I built a simple test: It has an InjectJsScript inside of a BrowserScrope which calls this Javascript function.

function(element, inputFromRPA) {
	DoSomething();
	return true;
}

The DoSomething() function is on the page.

And it returns:
RemoteException wrapping UiPath.Core.ElementOperationException: ReferenceError: DoSomething is not defined —> RemoteException wrapping System.Runtime.InteropServices.COMException: ReferenceError: DoSomething is not defined

I have tried placing the DoSomething() function within the < head > and < body > elements, using both Chrome and Edge but to no avail.
