Use data-* attributes [1], or print it in a script tag with a text/anything type:

    <script type="text/json" id="mydata">
        { data: "..." }
    </script>

    var data = JSON.parse($('mydata').textContent)

If you put it in a script tag you need to ensure you escape </script>. Though, it is probably safer to escape <, >, and & just to be sure.

The </script> issue is why JSON and Javascript both allow you to escape the slash character with a backslash.

So just going <\/script> is enough.
