downloads.show()

The show() function of the downloads API shows the downloaded file in its containing folder in the underlying platform's file manager.

This is an asynchronous function that returns a Promise.

Syntax

let showing = browser.downloads.show(
  downloadId             // integer
)

Parameters

downloadId: An integer representing the ID of the DownloadItem to show.

Return value

A Promise. If the request succeeds, the promise will be fulfilled with a boolean about whether the request was successful. If the request fails, the promise will be rejected with an error message.

Browser compatibility

BCD tables only load in the browser

Examples

This example shows the most recently downloaded item:

function onShowing(success) {
  console.log(`Showing download item: ${success}`);
}

function onError(error) {
  console.log(`Error opening item: ${error}`);
}

function openDownload(downloadItems) {
  if (downloadItems.length > 0) {
    latestDownloadId = downloadItems[0].id;
    let showing = browser.downloads.show(latestDownloadId);
    showing.then(onShowing, onError);
  }
}

let searching = browser.downloads.search({
  limit: 1,
  orderBy: ["-startTime"],
});

searching.then(openDownload, onError);
