Question

I’m making a javascript metro app and have some code like this:

    <script>
       document.writeln(foo());//this line is trouble
    </script>

and when I tried to run, it gave me a rather long error:

Unhandled exception at line 20, column 9 in ms-appx://a375ffac-3b69-475a-bd53-ee3c1ccf4c4e/default.html

0x800c001c – JavaScript runtime error: Unable to add dynamic content.
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.

How can I get around this?

Answer 1

regarding to the docs I would try :

document.writeln(window.toStaticHTML(foo()));
