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 setInputMethodActive() method of the HTMLIFrameElement sets the current browser <iframe> as an active Input Method Editor (IME) window and other iframes as non-active IME windows. Useful when a top level app wants to activate a window as an IME.
Syntax
instanceOfHTMLIframeElement.setInputMethodActive(boolean);
Returns
A DOMRequest object that handles the request to set this feature. It has an onsuccess handler that fires if the setting is successful, and an onerror handler that fires if not.
Parameters
A Boolean that indicates if we want to set the current frame to the active IME window (true) or not (false.)
Example
var browser = document.querySelector('iframe');
var request = browser.setInputMethodActive(true);
request.onsuccess = function() {
// success!
}
request.onerror = function(error) {
console.log(error);
}
Specification
Not part of any specification.
