Yii2 submit link with Ajax

Question

I'm trying to create votes for my content in Yii2, so I'm trying to insert data with Ajax using "a" tag and widget but with ajax it's not working , without ajax it's working perfect. but when I use Ajax it's not working and I have no errors in console. my code for view is :

<script type="text/javascript">
    $('document').ready(function(){
        $('#btn-vote-up' + <?= $pst_id ?>).on("click", function(e){
            $.ajax({
                type: "POST",
                data: {"value" : "Like"},
                success: function(msg) {
                    console.log (<?= $pst_id ?>);
                    $('#note-up' + <?= $pst_id ?>).load(' #note-up' + <?= $pst_id ?>);
                }               
            });
            e.preventDefault();
        });
    });
</script>


    <?= Html::a('<i class="ly-ic-favorite-plus"></i>', '#', [
                'class' => 'btn-logout',
                'id' => 'btn-vote-up'.$pst_id,
                'data'  => [
                    'params' => [
                        'value' => 'Like',
                        'pstIDL' => $pst_id,
                        ],
                    ],
        ]) ;
    ?>
    <?php yii\widgets\Pjax::begin(['id' => 'note-up'.$pst_id]) ?>
        <span><?= $total_up ?></span>
    <?php yii\widgets\Pjax::end() ?>

And my widget code is :

if (Yii::$app->request->post('value') == 'Like')
            {
                $pstIDL = Yii::$app->request->post('pstIDL');

                $modelLIKEPOST = $this->findLikePost($pstIDL);

                AxVotePost::VoteUP($modelLIKEPOST, $this->usr_rid, $this->chn_id, $pstIDL);
                header('Location: ' .Url::current() );
                exit;
            }

You are not sending the $pstIDL value when making an ajax call and only value is being sent, you can use var data=$(this).data('params') to get both pstIDL, and the value json and send it along the data in the call see below

<script type="text/javascript">
    $('document').ready(function(){
        $('#btn-vote-up' + <?= $pst_id ?>).on("click", function(e){
           var data= $(this).data('params');
            $.ajax({
                type: "POST",
                data: data,
                success: function(msg) {
                    console.log (<?= $pst_id ?>);
                    $('#note-up' + <?= $pst_id ?>).load(' #note-up' + <?= $pst_id ?>);
                }               
            });
            e.preventDefault();
        });
    });
</script>
