Fullscreen in OSWeb

goran123

Hi! When we run our experiment online it is not in full screen (it is centered on the screen, but we can see the screen (two white stripes) on the left and on the right side). How can we show our experiment in full screen?

Hi!

To get the browser into fullscreen mode you'd usually use Element.requestFullscreen(). Did you try this already?

Best,

Kristian

I've moved your question to the OSWeb forum - they can help

Hi @goran123,

You can try enabling the "Make browser full screen" in the OSWeb settings and this should work if your browser supports this function. Note however that some objects (like forms) then become unresponsive (due to a security feature of browsers). In that case, you can use code to enable the full screen mode in the early stages of the task. You can find relevant information in this previous thread (somewhere down the middle):

Running experiments online using OSWeb

Hi,

I have been using Opensesame for several years and it worked really well. I am now trying to run a lexical decision study online, but I had the following error:

uncaught typeerror: cannot read properties of undefined (reading 'apply') see the console for further details

The source of the error seems to be my two in-line scripts: one for recording the handness of participants (so that they pressed the 'yes' button with their dominant hand), the other is to counterbalance.

In-line script 1:

if var.response_handedness_response =='l':

var.y_response='z'

var.n_response='m'

else:

var.y_response='m'

var.n_response='z'

In-line script 2:

if self.get('subject_nr')%8 == 1:

b1 = 0

b2 = 10

b3 = 10

b4 = 10

b5 = 10

b6 = 10

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 2:

b1 = 10

b2 = 0

b3 = 10

b4 = 10

b5 = 10

b6 = 10

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 3:

b1 = 10

b2 = 10

b3 = 0

b4 = 10

b5 = 10

b6 = 10

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 4:

b1 = 10

b2 = 10

b3 = 10

b4 = 0

b5 = 10

b6 = 10

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 5:

b1 = 10

b2 = 10

b3 = 10

b4 = 10

b5 = 0

b6 = 10

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 6:

b1 = 10

b2 = 10

b3 = 10

b4 = 10

b5 = 10

b6 = 0

b7 = 10

b8 = 10

elif self.get('subject_nr')%8 == 7:

b7 = 0

b8 = 10

b9 = 10

else:

b1 = 10

b2 = 10

b3 = 10

b4 = 10

b5 = 10

b6 = 10

b7 = 10

b8 = 0

exp.set('b1',b1)

exp.set('b2',b2)

exp.set('b3',b3)

exp.set('b4',b4)

exp.set('b5',b5)

exp.set('b6',b6)

exp.set('b7',b7)

exp.set('b8',b8)

I deleted the first online script and changed the second into the following Javascript using an online converter, but I still got the same error message.

I am now unsure of what to do to solve the error. Do you have any suggestions? Thanks so much in advance!

Hope this helps,

Fabrice.
