title: Force iframe to Load Full Frame
body: <p>I have an HTML page (say welcome.html) which contains an iframe to a page I have no control over (say app.html).  The user performs some actions using the app within the iframe and clicks submit.  Once they do this, they are taken to a new page (say thanks.jsp), which loads within the iframe.  Is there a way in which I can force thanks.jsp to load in the full frame and not the iframe once submit is clicked?  Remember, I have no control over the logic behind that Submit button or app.html.  I do however have control over welcome.html and thanks.jsp.  If possible, I would like to stick with HTML and/or JavaScript.  Thank you in advance.</p>
