Rails 3.1 Having iframe in view makes layout stop rendering
So I have a basic layout file:
<!DOCTYPE html>
<html dir="ltr" lang="en-US">
<head>
<%= stylesheet_link_tag "logged_out" %>
<%= javascript_include_tag "application" %>
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/themes/ui-lightness/jquery-ui.css" %>
</head>
<body>
<!-- header stuff here -->
<%= yield %>
<!-- footer stuff here -->
</body>
</html>
And with any normal html its fine. However if I add in an iframe like this to a view:
<ifr开发者_如何学Pythoname id="form" height="480" width="320" src="/mobile_preview/preview"/>
When I render the page everything is rendered up until the iframe, but the footer stuff after yield doesn't render. Has anyone run into this before?
EDIT: As one of the answers pointed out (thank you!), my yield statement in my initial question was wrong. My yield statement in my code is correct though, it was a typo when transferring to stackoverflow.
NOTE: If you are trying to replicate the iframe is using jquery mobile.
The problem is how you include <iframe>. You think you included self-closing tag, and it ends there. But you don't send your page as XML, and HTML doesn't have concept of self-closing tags, it's just garbage at the end. So your:
<iframe id="form" height="480" width="320" src="/mobile_preview/preview"/>
is really interpreted as:
<iframe id="form" height="480" width="320" src="/mobile_preview/preview">
and rest of the page is interpreted as ignored content inside <iframe> tag. That's why you shouldn't use self-closing tags in HTML document - they don't really work the way you think they work.
Change it to:
<iframe id="form" height="480" width="320" src="/mobile_preview/preview"></iframe>
You could found it if you looked at parsed DOM tree with Firebug or Chrome Inspector.
As a bonus: it has nothing to do with Rails, server returns response just as previously, you could see it in logs. It's just a matter how your markup is interpreted by browsers.
You have wrong on clossing ruby code place
<%= yield =>
The correct is
<%= yield %>
