problem accessing URL query parameters

[Becky Gilbert]

Hi JATOS users,

I'm having problems accessing URL query parameters using the jatos.urlQueryParameters object described here: http://www.jatos.org/jatos.js-Reference.html#original-url-query-parameters. I'm using JATOS version 3.1.12.

I'm trying to use jatos.urlQueryParameters in the first study component but it always returns undefined. For example, this:

$(function() {
    jatos.onLoad(function() {  
        ....
        console.log('URL parameters: ', jatos.urlQueryParameters);
        ....
    });
});

always gives me:

URL parameters:  undefined

This is true regardless of whether I run the study inside JATOS or outside (using a General Single or Personal Multiple worker link), and regardless of whether I add my own query string to the end of the link (e.g. "&foo=bar"). Any thoughts on what I might be doing wrong? Is there any more documentation on this that I might have missed, or examples studies on jatos.org that show how it's used?

Many thanks,

Becky

Hi Becky again,

I just tried the URL query parameters with both Personal Single Worker and Personal Multiple Worker and at least with my local JATOS it worked fine. Here is a screenshot:

What did your URL with query parameter looked like? Maybe you missed an '&'?

Hi Kristian,

Thanks very much for looking into this. The good news is that this is now working perfectly. The bad news is that I can't reproduce the original problem (it just started working, so I guess I must have edited the file but I'm not sure what I changed). If I figure out what I was doing wrong, I'll post it here for the benefit of others.

Thanks again!

Becky
