Css主题对jquery更改无效

Question

我遇到了一个非常奇怪的问题，使用css主题和jquery。

我在网页上应用了自定义css主题，页面看起来很棒。现在我使用jquery执行了一些操作。就像点击一个复选框一样，其他复选框会被选中，一些复选框会被禁用。

奇怪的是，页面看起来仍然一样。这是检查/禁用的复选框仍然具有与jquery操作之前相同的图像。

我的同事告诉我，我必须在每次jquery操作后应用css类。喜欢每次选中/取消选中复选框

是假设是这样还是我做错了什么？我的印象是，一旦安装了主题，css就会保持一致。

任何建议......

谢谢..

编辑：

代码很广泛，但我附加了uniform-default.css文件和用于申请的js文件。如果您需要更多代码，请与我们联系。
