jquery - Replacing a text value in a table cell with Javascript -


i struggling mask data value javascript. work @ school, , doing away "traditional" grading. such, don't want gradebook display percentages, instead show words based on percentages (yeah know). replace % value word string. js, correctly alerts me values, return value never replaces % value in cell. missing? extremely new js may simple mistake.

$('.percentage').each(function() {    var corrected = $(this).html();    corrected = parsefloat(corrected);    alert(corrected);    switch (true) {      case (corrected < 48.75):        return 'unsatisfactory';        break;      case (corrected < 61.25):        return 'approaching ';        break;      case (corrected < 73.75):        return 'approaching+ ';        break;      case (corrected < 86.25):        return 'meeting ';        break;      case (corrected < 94.9):        return 'meeting+ ';        break;      case (corrected <= 100):        return 'exceeding ';        break;      default:        return 'n/a';    }    })
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

this do. parses text of cell , replaces string-value based on current score.

$(".score").each(function() {    var $this = $(this);    $this.text(() => {      var num = parsefloat($this.text());      var val;      if (num < 48.75)        val = 'unsatisfactory';      else if (num < 61.25)        val = 'approaching ';      else if (num < 73.75)        val = 'approaching+';      else if (num < 86.25)        val = 'meeting';      else if (num < 94.9)        val = 'meeting+';      else if (num <= 100)        val = 'exceeding';        return val;    });  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <table>    <tr>      <td>score</td>      <td class="score">48.75</td>    </tr>    <tr>      <td>score</td>      <td class="score">38.25</td>    </tr>    <tr>      <td>score</td>      <td class="score">85.12</td>    </tr>    <tr>      <td>score</td>      <td class="score">67.50</td>    </tr>    <tr>      <td>score</td>      <td class="score">87.80</td>    </tr>    <tr>      <td>score</td>      <td class="score">10.50</td>    </tr>    <tr>      <td>score</td>      <td class="score">96.50</td>    </tr>  </table>

the class on td makes sure you're parsing cells actual score.
