How to handle dynamic download link to download a file? #23

A big thumbs-up to the contributers for this amazing node. Makes life a lot easier.

I am not able to understand how to download a file which gets downloaded after clicking the element which is formatted as follows.

`

Export as CSV

                            <i class="glyphicon glyphicon-cloud-download"></i>
                            <span ng-show="csvFailed" class="hide ng-hide">CSV download failed, Please try again.</span>
                        </div>`

This would, after 4-5 seconds start the download in a new pop up window. How can save the downloaded csv?

Did you fill out the onDownload method? From the documentation:

onDownload Use this method to save a downloaded item from the web. Be sure to add this method before the gotoURL method or prior to invoking a download link. file - The path and filename of the item to be downloaded. output - An existing context property to return the download results to or flow output (default). When using a flow output, the download results will be in msg.payload.

Yes I tried that. It is not a direct url or link. It runs a JavaScript and opens a new window for the download link. I need to download the file opened in the new window.

Your best bet is to determine the URL it is attempting to open in a new window and use gotoURL, after the onDownload method.
