Since it sounded like
jQuery was an option for Metro JavaScript apps, I was starting to look forward to Windows 8 dev. I installed Visual Studio 2012 Express RC and started a new project (both empty and grid templates have the same problem).
I made a local copy of
jQuery 1.7.2 and added it as a script reference.
<!-- SomeTestApp references -->
<link href="/css/default.css" rel="stylesheet" />
<script src="/js/jquery-1.7.2.js"></script>
<script src="/js/default.js"></script>
Unfortunately, as soon as I ran the resulting app it tosses out a console error:
HTML1701: Unable to add dynamic content ' a' A script attempted to inject dynamic content, or
elements previously modified dynamically, that might be unsafe. For
example, using the innerHTML property to add script or malformed HTML
will generate this exception. Use the toStaticHTML method to filter
dynamic content, or explicitly create elements and attributes with a
method such as createElement. For more information, see
http://go.microsoft.com/fwlink/?LinkID=247104.
I slapped a breakpoint in a non-minified version of
jQuery and found the offending line:
div.innerHTML = " <link/><table></table><a href='/a' style='top:1px;float:left;opacity:.55;'>a</a><input type='checkbox'/>";
Apparently, the security model for Metro apps forbids creating elements this way. This error doesn't cause any immediate issues for the user, but given its location, I am worried it will cause capability-discovery tests in
jQuery to fail that shouldn't.
I definitely want
jQuery $.Deferred for making just about everything easier. I would prefer to be able to use the selector engine and event handling systems, but I would live without them if I had to.
How does one get the latest
jQuery to play nicely with Metro development?
