JavaScript functions in the manual

  Hi,

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

  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.
