This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The delete()
method of the Cache
interface finds the Cache
entry whose key is the request, and if found, deletes the Cache
entry and returns a Promise
that resolves to true
. If no Cache
entry is found, it returns false
.
cache.delete(request,{options}).then(function(true) { //your cache entry has been deleted });
a Promise
that resolves to true if the cache entry is deleted, or false otherwise.
Request
you are looking to delete.delete
operation. The available options are: ignoreSearch
: A Boolean
that specifies whether the matching process should ignore the query string in the url. If set to true
, the ?value=bar
part of http://foo.com/?value=bar
would be ignored when performing a match. It defaults to false
.ignoreMethod
: A Boolean
that, when set to true
, prevents matching operations from validating the Request
HTTP
method (normally only GET
and HEAD
are allowed.) It defaults to false
.ignoreVary
: A Boolean
that, when set to true,
tells the matching operation not to perform VARY
header matching. In other words, if the URL matches you will get a match regardless of whether the Response
object has a VARY
header. It defaults to false
.cacheName
: A DOMString
that represents a specific cache to search within. Note that this option is ignored by Cache.delete()
.caches.open('v1').then(function(cache) { cache.delete('/images/image.png').then(function(response) { someUIUpdateFunction(); }); })
