Question

好的，抱歉标题，我想不出要叫什么。

我正在设计HTML5和JavaScript的智能电视界面。到目前为止我得到的是div充满假电影名称（用于测试目的）。我不认为它一直在运行，但这是一个演示：https://xviuw-cheapskate01.c9.io/。

我想要做的是检测所选的div是否在它的第3到第一个div和它的第3个到第一个div之间＆＃ 39; s班。如果是，我希望整个包含div的左值移动-230px。

我算出了这个等式。虽然它没有用，但你应该得到这个想法。

(index - 2) * -220 + "px"

我尝试过很多东西，但都没有。

这是我的代码。

JS：

var selected;

$(document).ready(function() {
  $(".movie-section .movie:nth-child(1)").addClass("movie-selected");
  selected = $(".movie-selected");

  $('html').keydown(function(e){
    if (e.keyCode == 39) {
      if (selected.is($(".movie-section .movie:last-child"))) {

      } else {
        $( ".movie-selected + .movie" ).addClass("movie-selected");
        $( selected ).removeClass("movie-selected");
        selected = $(".movie-selected");

      }
    }

    if (e.keyCode == 37) {
      if (selected.is($(".movie-section .movie:nth-child(1)"))) {

      } else {
        $( ".movie-selected" ).prev().addClass("movie-selected");
        $( selected ).removeClass("movie-selected");
        selected = $(".movie-selected");
      }
    }
  });

});

HTML：

<!DOCTYPE html>

            </header>
            <div class="movie-section">

                        <img ng-src="{{ movie.cover }}"> 
                        <p class="title">{{ movie.name }}</p>
                        <p>{{movie.rating}}</p>
                        <p>{{movie.length}}</p>
                    </div>
                </div>
            </div>
        </div>

</html>
