JavaScript functions in the manual

DahmSF

Hi Sebastiaan,

if i go into the manual i see many more python functions than JavaScript functions.

Now my question is:

Are these functions just not reported in the manual or do they not work in OSWeb?

To make an example: If i would like to set up my experiment with inline_JavaScripts only, i will need the keyboard and mouse response functions as well as logging functions.

If these basic functions are just missing in the manual, it would be great to add them in the manual as for the basic python functions. If they do not work yet in OSWeb, that would probably be something for future developing 😉

Regards,

Stephan

PS: Your videos are great! I always enjoy watching them.

Hi,

Unfortunately, they don't exist (not just not documented)

i will need the keyboard and mouse response functions as well as logging functions.

I don't know about the logger, but keyboard and mouse do not exist yet for javascript. However, there are ways to interact with mouse and keyboard events in javascript. They are just outside the scope of Opensesame, so you need to learn some plain javascript. See for example the first response of @Fab in this discussion here

Hope this helps,

Eduard

Hi @DahmSF,

You can find some information about the objects and variables that can be edited or manipulated from Javascript here (including the log): https://osdoc.cogsci.nl/3.3/manual/osweb/osweb/

You can also use the browser's debugger to explore all the variables and arrays in memory and manipulate them. It takes some work if you're not that familiar with it (as is my case), but it is feasible. See https://forum.cogsci.nl/discussion/7412/accessing-and-manipulating-loops-in-javascript#latest for an example of how to manipulate loops.

OSweb 1.4 offers more control than previous versions, but presently you can't use Javascript to create keyboard or mouse objects through code. You can however probably edit some of their properties from Javascript once you've created them using OS's visual interface. So for now, you'll probably have to create the mouse and keyboard objects using the visual interface instead of through coding.

Best,

Fabrice.

Hi @DahmSF and @Fab ,

Perhaps these (new) articles are also useful:

• https://osdoc.cogsci.nl/3.3/manual/javascript/common/

Cheers,
