title: Tableau - How to make parameters available outside iFrame
body: <p>We have a view in Tableau. This view is then embedded in an iFrame. The view has various tabs and various dropdowns. All these are parameters.</p>
  
  <p>We have a link within the view, which when clicked will take the user to a page where they can add comments against the very specific view they're on e.g. which tab they are on and what selections they have made in the dropdowns</p>
  
  <p>My question is rather than this - is there anyway the parent page can capture this information after the user makes the selection? The link the user currently gets redirected to is similar to this:</p>
  
  <p><a href="http://domain.com/comment.asp?URL=http://tableau/views/VIEW_NAME/LandingPage&amp;params=SOMETHING=THAT,THIS=ELSE,ABC=123" rel="nofollow">http://domain.com/comment.asp?URL=http://tableau/views/VIEW_NAME/LandingPage&amp;params=SOMETHING=THAT,THIS=ELSE,ABC=123</a></p>
  
  <p>The script then looks at the params querystring and processes that data against "LandingPage"</p>
  
  <p>Alternatively - if there's a better way to capture user comments for a specific view (I realise that "view" can mean various things here!) then I'm all ears</p>
  
  <p>Thanks</p>
