      // This is JSHint, a tool that helps to detect errors and potential
      // problems in your JavaScript code.
      //
      // To start, simply enter some JavaScript anywhere on this page. Your

我认为以下内容应该有效。

  ... truncated ...

  <script type="text/javascript">
    function main()
    {
        var scriptContent = document.getElementById('text-intro').textContent;
        // You can symbols here for jsHint to assume are existing.
        var globals = {
            jQuery: true // Assume that jQuery is defined and don't report it as an error.  
        };
        // Options to pass to jshint, see the docs.  Here are some examples.
        var options = {
            /* '-W034': true */
            /* 'camelcase': true */
            /* 'predef': ['-window'] //  remove a normally predefined var */
            /* exported: ['MyVar'] // tell jshint this var is used in another file */
        };
        JSHINT(scriptContent, options, globals);
        // Now do something with JSHINT.errors
    }
    main();
  </script>
