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);
You can see this code in action in our latest-download example.
