Is it possible to update file content before uploading it?

  • Hi,

    You can access the content of the file before uploading with the help of onBeforeFileAdd event

    $$("uploader").attachEvent("onBeforeFileAdd", function(record){
       record.file = some_processing(record.file);
    });
    

    record.file is a blob of data, content of the file. You can change it in a necessary way.
