I put a ticket on this, but maybe somebody tried it before.
I need to upload image file into Knack assets by using Javascript.
What I have is just the text variable with url pointing to the file on external server.
I understand that I have to write a code to download file first into the browser memory, than wait till it loads, and than prepare ajax call to Knack.
Or maybe it is better way?
I am not using PHP, Phyton or anything else besides Javascript & jQuery, so I would appreciate code sample in this language - I would like to understand what I do ;-)
Thanks in advance
Andrzej
