Cannot get startComponent to work

steffejr · January 2023

I am trying to the "startComponent" function using the ID of each task in my JATOS project. It does not work though. I do not even get any errors. Where in my code do I add the jatos.startComponent(##) so that it works?

A full example would be really appreciated.

Thank you

Hi,

Maybe you don't put it inside the jatos.onLoad? Anyway here is simple example

<!DOCTYPE html>
<html>
<head>
    <script src="jatos.js"></script>
</head>

<body>
    <p>Press any key to continue</p>
    <script>
        jatos.onLoad(function () {
            // Wait for any key press and start next component
            document.onkeypress = function (e) {
                // Using the component's UUID
                jatos.startComponent("2502c4b4-9aba-4703-8d4f-fa034300ca5c");
                // Using the component's ID
                //jatos.startComponent(3);
                // Just jump to the next component
                //jatos.startNextComponent();
            };
        });
    </script>
</body>
</html>

Best,

Kristian

Hello Kri,

Thank you for the response. I have tried that and it also does not work. The code as you have it provided me with an error saying the component does not exist. Which is good. When I add my own UUID I do not even get an error, I am brought straight back to the JATOS interface. Any ideas? I am working with JATOS local.

Just to be clear, when you use jatos.startComponent("my-uuid") you use the UUID of the component you want to jump to, as specified in the Component Properties, right? And another questions: Which JATOS version do you use?

Hello Kri,

Sorry that I wasted your time. It works.

I was pressing the run button of the component and not the run button for the study

Thank you,
