I have the following question
Is it possible to detect with some listener or something with js when downloading a pdf that is hosted in an iframe?
I have not been able to detect something similar so far
<td colspan="7" height="400px">
                              
                                <iframe name="iframeid" id="iframeid" src='urlTempPDF' width="100%" height="100%">
                                    </iframe>
                            </td>
I want to detect when the download starts and if the document has been downloaded correctly.
