h2 class="dtitle"为什么选择whatsns/h2
p class="huitext"1、可以满足在垃圾虚拟主机运行流畅/p
p class="huitext"2、傻瓜式安装，快速采集，快速SEO优化内容/p
p class="huitext"3、轻松配置对接熊掌号，火车头采集，xunsearch,OSS/p
p class="huitext"4、PC和wap模板分离自由组合终端展示效果/p
p class="huitext"5、网站从注册，登录，防灌水，内容优化，内容采集挖掘，网站运营等方方面面为站长深度定制细节/p
p class="huitext"6、超强大的功能配置，自由开关前端功能/p
p class="huitext"7、深度挖掘问答，文章，课程内容付费，让站长没有难赚的钱/p
p class="huitext"8、解决内容付费终端支付问题，您可以在PC，wap和微信端，APP中动态调用不同底层支付方案解决内容付费问题label class="label-danger"独家/label/p
p class="huitext"9、支持微信语音回答，自动转码，任何终端可以收听语音回答label class="label-danger"独家/label/p
p class="huitext"10、性价比超值，货比三家，市面上没有任何一家问答+课程的开源系统能和我们比，有的一个终端（要么只有pc模板，要么只有wap模板）15000多人民币，有的只有问答模块，一套就是20000多人民币只包含卖系统钱，技术支持单算，选择我们是花一份钱买多个终端可用的产品，而且功能都碾压其他家。/p

你没有引入js库
script type="text/javascript" src="jquery-1.8.3.min.js"/script
把上面这一行放在 shuiyin js 的上面
库自己去下载就可以。。
希望对你有帮助。
