Question

我目前在我的网站上配置flexslider时遇到问题。我正在使用elixir laravel和凉亭。

我已经编译了所有scss，less和js文件，但是当我在主页上添加与滑块相关的任何代码时，我收到此错误：

Uncaught TypeError: $(...).flexslider is not a function using

似乎没有任何内容出现在我的网页上

我在layout.blade文件中添加了javascript只是为了测试

        };
        timer_metaslider_158();
    </script>




    </body>
</html>

这是我希望我的滑块显示的页面：

@extends('layout')

@section('content')

<!-- Place somewhere in the <body> of your page -->
<!-- Place somewhere in the <body> of your page -->
<div class="flexslider">
  <ul class="slides">

      <iframe id="player_1" src="http://player.vimeo.com/video/39683393?api=1&player_id=player_1" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
    </li>
    <li>
      <img src="./images/maja.jpg" />
    </li>
    <li>

  </ul>
</div>
<div class="container">

            </div>
        </div>
    </div>
</div>

这是我的gulp.js文件

var elixir = require('laravel-elixir');

elixir(function(mix) {
    // Copy Styles
    mix.copy('bower_components/bootstrap/scss/', 'resources/assets/sass/libraries/bootstrap/')
       .copy('bower_components/css-hamburgers/_sass/hamburgers', 'resources/assets/sass/libraries/hamburgers/')

    .version(['css/app.css', 'css/style.css', 'js/app.js']);
});

任何帮助将不胜感激！

Answer 1

出于兼容性原因，你应该像这样包装你的jquery代码：

(function($){

  // jQuery code is in here

})(jQuery);

Answer 2

您需要确保文档在执行之前已完全加载，或者app.js中的JavaScript实际上可能需要比预期更长的时间来包含您的库，这将导致此错误。

相反，我们可以将$替换为jQuery，我们可以bind to the .ready()这样处理：

jQuery(function($){
    //your code
});

这减少了在闭包中将jQuery别名为$，然后在其中执行就绪函数的需要。

未捕获的TypeError：$（...）。flexslider不是使用gulp和bower的函数
