问题 I would to make the iFrame to appear on fullscreen with a button click using JavaScript. <iframe id="iframe_view" class="embed-responsive-item container well well-small span6" style="height: 720px; width: 1280px; background-color: #2e2e2e;" src="https://www.google.com/" frameborder="0" scrolling="no" allowfullscreen> 回答1: You will have to do two things: make the window fullscreen, and then the <iframe> to fill up the whole size. You can make it go fullscreen with JS such as in this SO answer.
