How to clear content of div container using JS/Jquery?
===

I have been developing some page and I need to clear a content of some div:

                    <table>
                        <tbody>
                        <div class="records_content">
                            <?php
                                $i=0;
                                foreach ($records as $record) {
                                    echo "<tr class = 'output' style='border-bottom: 1px dotted silver;'>";
                                    echo "<td width='400'>" . strip_tags($record['language_value']) . "</td>";
                                    if ($record['approved_translation'])
                                    {
                                        echo "<td width='200' height='30'><div class='field' id='".$record['label_value']."/".$record['language_id']."'>".
                                            strip_tags($record['approved_translation']['language_value'])."</div></td><td><button class='btn btn-info' id='{$record['label_value']}/{$record['language_id']}' href='#'>More...</button>"."</td>";
                                    }
                                    else
                                    {
                                        echo "<td  width='200'>"."<div id='".$record['label_value']."/".$record['language_id']."'><span class='no_translate'>Not translated</span></div>" . "</td>";   
                                    }                   
                                    echo '</tr>';
                                    $i++;
                                }
                            ?>
                        </div>
                        </tbody>
                    </table> 

Piece of JS code:

 

               $(".page_button").click(function () {
                    $.post("http://"+document.location.host+"/index.php/welcome/update_records_set/"+this.id,
                        function(data)
                        {
                            alert('123');
                            $(".records_content").empty();
                        });
                });

This script works, because I see '123' notification, but div container with '.records_content' class isn't clear. Please, tell me, how can I fix it? Thank you.
