Is there a way to read many files?

[gkim132]

Hi,

I need to use a lot of image files stored in several folders.
I'm wondering if there is a way to read all files easily instead of listing all the file names.
what I mean listing all the file names is: imgSet_1 = ["a/1.png","a/2.png","a/3.png", ... ]
imgSet_2 = ["b/1.png","b/2.png","b/3.png", ... ]
...
imgSet_10 = [...]

Any help will be greatly appreciated!

Thank you!

Due to security reasons, browsers cannot do this. However if you know how to use a programming language, this can be easier.

In R, after you install or verify that you have the jsonlite package, you can do this and copy paste the output.

jsonlite::toJSON(list.files("/path/to/folder", recursive=TRUE))

Hello! I am also encountering this problem now, did you solve it?

Hi ineminor,

As vijaymarupudi mentioned, this is not possible using Javascript and jsPsych itself. In stead, you use another programming language such as R or Python to list all the files in a folder such as your image folder. You then create a json string which you copy paste into your javascript code.

To make this more specific, the following array in your Javascript code:

["a/1.png","a/2.png","a/3.png", ... ]

is a string that was generated in another programming language.
