javascript - Why doesn't setting frame src by js show the display source? -

-

based on js condition, want either of 2 things happen;

  1. either show frame on page or
  2. show link "show pdf" on page.. show pdf

now while know how show/hide based on js condition, question in case 2nd condition satisfied, not want hide frame thing, ensure not loaded in background well... think using show/hide not stop loading pdf in background.. question how can acheive using javascript?

**********here trying**********

if(isipad)          {              $('#content').attr('src','ipad_frame.html');          }          else          {              $('#content').attr('src','xyz.pdf');          }

and in html, have

 <frame src="#" title="content frame" name="content" id="content" />

will work fine? reasons, tested , though goes in if/else part, not show relevant content..

why not add elements dynamically in script container element? (assuming you're using jquery):

if(condition) {     $('#container').html('<html frame>'); } else {     $('#container').html('<html pdf>'); }

this ensure item want load loaded.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
