You can put you JS function not in external file. Insted of it put it in your html file like this:

<script>
    function drawImage ()
    {
         // your computataion 
    }
</script>
// or connect your js functions from external file 
<script src="test.js"></script>

And then call it from code

cwv.loadUrl("javascript:drawImage('"+jsonArray+"','"+ true+"')");

And pay attention to single quotation!

And the second mothod was described by Mocialov Boris.
