This is an asynchronous function that returns a Promise.

Examples

In general, you restrict the items retrieved using the query parameter.

Get downloads matching "query"

function logDownloads(downloads) {
  for (let download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

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

var searching = browser.downloads.search({
  query:["imgur"]
});

searching.then(logDownloads, onError);

Get a specific item

To get a specific DownloadItem, the easiest way is to set only the id field, as seen in the snippet below:

function logDownloads(downloads) {
  for (let download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

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

var id = 13;

var searching = browser.downloads.search({id});
searching.then(logDownloads, onError);

Get all downloads

If you want to return all DownloadItems, set query to an empty object.

function logDownloads(downloads) {
  for (let download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

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

var searching = browser.downloads.search({});
searching.then(logDownloads, onError);

Get the most recent download

You can get the most recent download by specifying the following search parameters:

function logDownloads(downloads) {
  for (let download of downloads) {
    console.log(download.id);
    console.log(download.url);
  }
}

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

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