未捕获的类型错误： 对象 [对象对象] 没有方法'Jcrop'

Question

一切似乎都已加载(jquery, jcrop和我的avatar.js文件)。我似乎不知道发生了什么事。我的脚本按照以下顺序加载:

<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery.Jcrop.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script>
<script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script>
<script src="/assets/bootstrap.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery-fileupload/vendor/jquery.ui.widget.js?body=1" type="text/javascript">         </script>
<script src="/assets/jquery-fileupload/jquery.iframe-transport.js?body=1" type="text/javascript">    </script>
<script src="/assets/jquery-fileupload/jquery.fileupload.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery-fileupload/basic.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery-fileupload/vendor/tmpl.js?body=1" type="text/javascript"></script>
<script src="/assets/avatars.js?body=1" type="text/javascript"></script>

avatars.js。咖啡包含以下内容:

jQuery ->
  new AvatarCropper()
class AvatarCropper
  constructor: ->
    $('#cropbox').Jcrop
      aspectRatio: 1
      setSelect: [0, 0, 600, 600]
      onSelect: @update
      onChange: @update
  update: (coords) =>
      $('#avatar_crop_x').val(coords.x)
      $('#avatar_crop_y').val(coords.y)
      $('#avatar_crop_w').val(coords.w)
      $('#avatar_crop_h').val(coords.h)
      @updatePreview(coords)
    updatePreview: (coords) =>
      $('#preview').css
        width: Math.round(100/coords.w * $('#cropbox').width()) + 'px'
        height: Math.round(100/coords.h * $('#cropbox').height()) + 'px'  
        marginLeft: '-' + Math.round(100/coords.w * coords.x) + 'px'
        marginTop: '-' + Math.round(100/coords.h * coords.y) + 'px'

在javascript控制台，我得到:

Uncaught TypeError: Object [object Object] has no method 'Jcrop' 

Answer 1

问题是jQuery.noConflict();

Answer 2

我也面临着同样的问题。我的问题得到解决，当我把我的jquery文件在jcrop.js.
