    HTMLIFrameElement.getVisible()

    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 getVisible() method of the HTMLIFrameElement is used to request the current visible state of the browser <iframe>.

    SyntaxEdit

    instanceOfDOMRequest = instanceOfHTMLIframeElement.getVisible();

    Returns

    A DOMRequest object to handle the getVisible() request's success and error cases. If the request is successful, the request's result is a Boolean indicating the visible state of the browser <iframe>.

    Parameters

    None.

    ExampleEdit

    var browser = document.querySelector('iframe');
var request = browser.getVisible();

request.onsuccess = function() {
  console.log('The visible state is: ' +
               this.result ? 'true' : 'false');
}

    SpecificationEdit

    Not part of any specification.
