top property
@DocsEditable(), @DomName('Window.top')
A reference to the topmost window in the window hierarchy.
If this WindowBase is the topmost WindowBase, top will return a reference to the WindowBase itself.
// Add an IFrame to the current window. IFrameElement myIFrame = new IFrameElement(); window.document.body.elements.add(myIFrame);
// Add an IFrame inside of the other IFrame. IFrameElement innerIFrame = new IFrameElement(); myIFrame.elements.add(innerIFrame);
print(myIframe.contentWindow.top == window) // 'true' print(innerIFrame.contentWindow.top == window) // 'true'
print(window.top == window) // 'true'
