how to request project file (array) by name

Hey I have a problem with how I want to stream in arrays.

Currently I have dialogues stored in seperate arrays and I want to stream them in via AJAX from the files folder.

They should be randomly selected. I thought I could do something like this :

Ajax request file: "Dialogue"&int(random(0,100))

But Construct doesn't allow picking by name only throught a dropdown in editor.

Am I missing something or is there a workaround.

Oh thanks so much, the URL word confused me, I thought I'd need to host the arrays externaly for that to work.

Thanks so much for the help!
