Yes. Start a script tag after the definition of $meaning and put the below code in it. Like.

document.getElementById('meaning').innerHTML = "<?PHP echo $meaning; ?>" ;

Also Can't you think of directly echo ing the value of $meaning inside the div without even using javascript? like

<div id = "meaning"><?PHP echo $meaning; ?></div>

You can also use the short form <?=$meaning?>.

 <div id="errorMessage"></div>
 <?php
  if (isset($_GET['q'])) {
  echo '<script type="text/javascript">
  document.getElementById("errorMessage").innerHTML = "User name or Password is incorrect";
  </script>';

  }
  ?>
