I realise that the online facility is still pre-release, here are some observations that might help with development, these are things that don’t translate correctly into JS, but could be made to work by editing the index.html file:
When I added strings to the beginning of each trial the units were specified as ‘‘height’’ not ‘height’ - (that’s two single inverted commas on each end rather than a single inverted comma). This caused it to hang.
I had 30 or so images in a sub-folder, there weren’t found correctly despite having the sub-dir in the experiment’s .csv file. (resource not found error). Things worked when I moved the images into the main folder and changed the .csv file.
The names of images that load directly (not specified in the .csv, just used for instructions) weren’t enclosed in inverted comma’s, adding the inverted commas fixed this.
The columns from my .csv file (image parameters and filenames) aren’t getting saved in the participant response file (.csv) - this might be my own omission - do I have to specify what values I want output?
