The erase
()
function of the downloads
API erases matching DownloadItems
from the browser's download history, without deleting the downloaded files from disk.
To remove the files from disk, you need to use downloads.removeFile()
.
Note: If you want to remove a downloaded file from disk and erase it from history, you have to call downloads.removeFile()
before you call erase()
. If you try it the other way around you'll get an error when calling downloads.removeFile()
, because it no longer exists according to the browser.
Syntax
chrome.downloads.erase( query, // DownloadQuery function(erasedIds) {...} // optional function )
This API is also available as browser.downloads.erase()
in a version that returns a promise.

Examples
The following snippet (taken from our latest-download example) shows the code that is run when the remove item button is pressed. Here we invoke both the erase()
and downloads.removeFile()
functions, which remove the file from the download history, and from the actual disk, respectively.
function removeItem() { if (!document.querySelector("#remove").classList.contains("disabled")) { chrome.downloads.removeFile(latestDownloadId); chrome.downloads.erase({id: latestDownloadId}); window.close(); } }
This pattern works for cases where you've got a single item to erase/remove.
To erase groups of items, use the relevant options in the query
parameter. For example, to erase everything, pass {}
:
function onForgot(items) { console.log("Forgot: " + items.length + " items."); } var forgetAllButton = document.querySelector("#forget-all"); forgetAllButton.onclick = function() { chrome.downloads.erase({}, onForgot); }
