{{Compat("webextensions.api.downloads.search")}}
En général, vous restreignez les éléments récupérés à l'aide du paramètre de requête.
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);
Pour obtenir un {{WebExtAPIRef("downloads.DownloadItem", "DownloadItem")}}, la méthode la plus simple consiste à définir uniquement le champ id, comme indiqué dans l'extrait ci-dessous :
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);
Si vous voulez renvoyer tout {{WebExtAPIRef("downloads.DownloadItem", "DownloadItems")}}, définissez la query sur un objet vide.
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);
