如何将JavaScript放入JavaScript中?

I've tried (but its not working):

<?php  
  $htmlString= 'testing';
?>
<html>
  <body>
    <script type="text/javascript">  
      var htmlString=<?php echo $htmlString; ?>;
      alert(htmlString);
    </script>
  </body>
</html>

Here is the tutorial that I've used for that purpose:

    Try this:

    <?php $htmlString= 'testing'; ?>
    <html>
      <body>
        <script type="text/javascript">  
          // notice the quotes around the ?php tag         
          var htmlString="<?php echo $htmlString; ?>";
          alert(htmlString);
        </script>
      </body>
    </html>
    

    When you run into problems like this one, a good idea is to check your browser for JavaScript errors. Different browsers have different ways of showing this, but look for a javascript console or something like that. Also, check the source of your page as viewed by the browser.

    Sometimes beginners are confused about the quotes in the string: In the PHP part, you assigned 'testing' to $htmlString. This puts a string value inside that variable, but the value does not have the quotes in it: They are just for the interpreter, so he knows: oh, now comes a string literal.
