Is `jatos.urlQueryParameters` deprecated? about jatos

Is jatos.urlQueryParameters deprecated?

No, it's not. I just tried it and it worked for me, returning an object. How do you call it in JS?

And it looks like the URL in the Reference seems to be a past version. The URL now does not contain the start?.

Yes, you are right, it's outdated. I'll update it. Thank you for pointing this out. Please, if you find more of those, tell me ;)

I use console.log(jatos.urlQueryParameters) at the top of the body part in my JS. The output in the console is as follows.

I also try to use the URL "http://127.0.0.1:9000/publix/[code]?foo=bar&a=123", but the output is still undefined.

I made a mistake in the updated docs: the first one is an ? - not an &. So it has to be http://127.0.0.1:9000/publix/[code]?foo=bar&a=123 like you already used :)

But it works for me. I just tried it:

Though you can only call it after jatos.js initialized. So, you have to call it from jatos.onLoad (https://www.jatos.org/Write-your-own-Study-Basics-and-Beyond.html#mandatory-lines-in-your-components-html):

jatos.onLoad(function() {
  console.log(jatos.urlQueryParameters);
}

Oh, that is indeed the main reason. But that means there seems to be no way to change my jspsych component parameters based on the prolific PID. Or I can define the component after jatos is initialized.

I'll try that later. Thanks for your help.

It should be no problem: The easiest is to just wrap all JS you have, including all jsPsych code, with jatos.onLoad:

jatos.onLoad(() => {
  // everything goes in here
}
