The Dispatchevent (evt) method of the M53 update after the Chrome browser does not trigger a file download

A classic JS foreground file download method:

1 varALink = document.createelement (' A ');2 varDatatype= "Data:text/plain;charset=utf-8,";3Alink.href = datatype+content;4Alink.download =filename;5 varEVT = Document.createevent ("htmlevents");//Create an event6Evt.initevent ("click",false,false);//This is a click event7Alink.dispatchevent (EVT);

Google thinks: "Click Hyperlink Download File" is a "default response", and the default response should not be triggered by the script, so starting from the M53 version of the ban all scripts triggered by the default response, the download method is invalid.

Temporary solution: Add the ALink to the DOM and let the user manually click on the hyperlink to download.
