Add a comment. Active Oldest Votes. I have a React component called FileDownload. All this component does is render a hidden form and then, inside componentDidMount , immediately submit the form and call it's onDownloadComplete prop.

Widget has corresponding action and store files. Widget imports FileDownload. Widget has two methods related to the download: handleDownload and handleDownloadComplete. Widget store has a property called downloadPath. It's set to null by default. When it's value is set to null , there is no file download in progress and the Widget component does not render the FileDownload component. The store saves the downloadPath and emits a change event.

Since there is now a downloadPath , Widget will render FileDownload passing in the necessary props including downloadPath as well as the handleDownloadComplete method as the value for onDownloadComplete. However, this time downloadPath is set to null. The store saves the downloadPath as null and emits a change event. Since there is no longer a downloadPath the FileDownload component is not rendered in Widget and the world is a happy place.

I see that the "onDownloadComplete" is called synchronously after submit, are you just making the assumption that there aren't any errors and that the server receives the request? Himmel Yes, sadly, this work around does not provide a way to confirm the file download was successful.
