Answer 1

您可以将 JS 函数放在外部文件中。将其放入您的 html 文件中，如下所示：

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

然后从代码中调用它

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

并注意单引号！

第二种方法由 Mocialov Boris 描述。
