Call custom function on click of upload.aspx - OK button

Hi All,

Is there a way to capture click event on library pop up upload.aspx (OK) and call a custom function ?

Usecase : User wants to upload file with samename but with different metadata,we have a dropdown HR & Finance. So the user can upload a document with same name in HR & Finance. Example: the user can upload document name WorkFromHomePolicies.pdf for HR department and for Finance department also.

So I was thinking if I could capture OK click event on upload.aspx, I was thinking we I could append timestamp in filename to make it unique.

Thanks in Advance, Jiniv Thakkar
