pause when fullscreen mode is left

[ccharlyy]

Hello,

i'm a beginner using jspsych and don't really know java script. I made an experiment where participants react to a large number of images pressing a key (html-keyboard-response plugin). The experiment has to be done in fullscreen mode. I used the enter fullscreen plugin, and added this function to the initialize jspsych variable to end the experiment when fullscreen mode is left:

	var jsPsych = initJsPsych({
			timeline: timeline,
			on_interaction_data_update: function(data){
				if(data.event == 'fullscreenexit'){
					jsPsych.endExperiment('The experiment was ended because fullscreen was exited');
				}
			}
		});

However, I'd like instead of ending the experiment to just pause the experiment when the participant leaves fullscreen, displaying a message thet they can take a break and resume the experiment by pressing a key (or button).

I tried a bunch of stuff and looked at similar questions on here, but i didn't manage to make it work. Could someone poitn me in the right direction on how i can implement this? Is it very complicated?

Thanks :)
