次のjqueryファイルがあります...インラインスクリプトまたは必要なイベントで$navPrevおよび$navNext関数に直接アクセスするにはどうすればよいですか。例えば:

    $("a").swipe( {
    //Generic swipe handler for all directions
        swipe:function(event, direction, distance, duration, fingerCount) {
             // My code here to move next or previous based on swipe action.
         ); 
             },
});

私は基本的にスライダーをスクロールするjqueryスワイプ機能を追加しようとしています。そのためには、次の関数と前の関数に直接アクセスできる必要があります。

(function( $, undefined ) {

 // Gallery object.

$.Gallery               = function( options, element ) {

    this.$el    = $( element );
    this._init( options );

};

$.Gallery.defaults      = {
    current     : 0,    // index of current item
    autoplay    : false,// slideshow on / off
    interval    : 2000  // time between transitions
};

$.Gallery.prototype     = {
    _init               : function( options ) {

これは私のHTMLコードです:

<div class="container">
        <!-- Codrops top bar -->
            <!--/ Codrops top bar -->
  <section id="dg-container" class="dg-container">
    <div class="dg-wrapper">

      <a href="#"><img src="album1.jpg" alt="image05"></a>
      <a href="#"><img src="album2.jpg" alt="image06"></a>
      <a href="#"><img src="album3.jpg" alt="image07"></a>

    </div>
                <nav>   
                    <span class="dg-prev">&lt;</span>
                    <span class="dg-next">&gt;</span>
    </nav>
  </section>
</div>

編集:スライダーがhtmlページから呼び出される方法は次のとおりです

<script type="text/javascript">
            $(function() {
                $me=$('#dg-container').gallery({
                    autoplay    :   true
                });
//              console.log($me);

            });
        </script>

まず、関数$navNext$navPrevはなく、単なるspan要素です。

<span class="dg-prev">&lt;</span>
<span class="dg-next">&gt;</span>

これを使用できます

$(".dg-prev")
$(".dg-next")

これらの要素に直接アクセスします。

したがって、swipeコードでは、次のように呼び出します。

$(".dg-prev").click();
