我在页面中的 jQuery 声明显然有问题：
http://www.northernvirginiapaintingcontractor.com 点击“绘制事实”
错误：“$.fn”为空或不是对象
指这一行：
$.fn.accordion = function () {
我正在将此声明用于另一个网站并且工作正常。
但是对于这个网站 - 这不能正常工作。
在网站上的一个单独页面中：GeneralContact jQuery 声明设置如下：
jQuery(document).ready(function ($) {
我没有足够的jQuery经验来调试这个，如果有人能看到问题，我将非常感激！
看来这个脚本在几个地方引用了 $： moredetail_click() hidedetail_click() based_set()
我不确定所有“$”引用是否有解决方法，或者我是否应该以某种方式重新编写它？
