javascript - 为什么我的 UI 应用嵌套在 Bootstrap 模式中时无法运行？

Question

我正在尝试改编 UI app由 codepen 用户 Fabio Ottaviani 构建，采用它的基本功能并将其放置在 Bootstrap 模式中。如果将它从模态中移除，它工作正常，但当放置在模态中时，它第一次工作，然后在重置后中断。重置 UI 后，courser 甚至不会变成指针/手。

var $play = $('.play'),
    $detail  = $('.detail'),
    $movie = $('.movie', $detail),
    $close = $('.close');

$('.movies .movie').click(function(){
  $movie.html($(this).html());
  $play.appendTo($movie);

  $poster = $('.poster', this).addClass('active');

  $('.poster', $detail).css({
    top: $poster.position().top,
    left: $poster.position().left,
    width: $poster.width(),
    height: $poster.height()
  }).data({
    top: $poster.position().top,
    left: $poster.position().left,
    width: $poster.width(),
    height: $poster.height()
  })

  $detail.show();

  $('.poster', $detail).delay(10).queue(function(next) {
    $detail.addClass('ready');

    next();
  }).delay(100).queue(function(next){
    $(this).css({
      top: '-10%',
      left: '-6%',
      width: 266,
      height: 400
    });
    next();
  })
})

  $p.css({

  $detail.removeClass('ready').delay(500).queue(function(next){

Answer 1

您遇到范围界定问题。查看应用程序的控制台日志时，我注意到错误

$poster 未定义

在查看您的代码时，我看到 $poster 被设置为某些内容，但范围限于 $('.movi​​es .movi​​e') 点击功能。该功能之外的所有需要​​使用它的东西都不知道它是什么。

解决这个问题的方法是将 $poster 添加到顶部的全局变量

var $play = $('.play'),
$细节= $('.细节'),
$movie = $('.movi​​e', $detail),
$close = $('.close'),
$海报;
