Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.
This API is available on Firefox OS for privileged or certified applications only.
The purgeHistory()
method of the HTMLIFrameElement
interface is used to clear the browsing history associated with the browser <iframe>
. It only deletes history, not cookies or other stored information.
Note: To delete cookies for a Firefox OS app, you could call clearBrowserData()
on the actual app itself.
Syntax
There is a DOMRequest
version and a Promise
version:
var myDOMRequest = instanceOfHTMLIframeElement.purgeHistory();
instanceOfHTMLIframeElement.purgeHistory().then(function() { ... });
Returns
Either
- A
DOMRequest
object that returns anonsuccess
handler if the history is deleted, or anonerror
handler if not. - A
Promise
that resolves, with no parameters, if the history is deleted, or rejects if not.
Parameters
None.
Example
var browser = document.querySelector('iframe'); var request = browser.purgeHistory(); request.onsuccess = function() { console.log('History deleted!'); } request.onerror = function() { console.error(this.error.name); }
var browser = document.querySelector('iframe');
browser.purgeHistory().then(function() {
console.log('History deleted!');
},
function(error) {
console.error(this.error.name);
});
