ace editor syntax validation html+javascript

Question

I'm using Ace Editor, and I'm trying to figure out how to get it to live syntax check the HTML markup AND JavaScript code in the editor.

If I set "ace/mode/html" only HTML syntax is checked, so in the following code

<!DOCTYPE HTML>
<html>
    <head>
        <title>Test</title>
    </head>
    <body>
        <h1>Hello World!</h1>
        <script>
            alert('This is a syntax error'+);
        </script>
    </body>
</html>

the JS syntax error is ignored by the editor.

Is there a way to tell to Ace Editor to check both HTML and Javascript?

Thank you very much!

THIS IS NOT A DUPLICATE OF How do I enable Live Syntax Checking in the Ace Editor

The question above explains how to execute syntax check HTML and JS in 2 separate editors, while I'm asking how to check them in the same one.

This does not solve my problem, it checks only html and it doesn't check javascript

check jshint and csslint checkboxes at the side of the page

Indeed, it seems that it is checking both html and javascript when I check the jshint box.
