摘要：基本思路:首先将小米商城的主页部分的导航区和底部区域部分写入此商品详情页内，并对此页面内大致分成3个大的div组成，第一部分是内容区导航部分，之后将下面整个大的内容区域左边放入轮播图，右边进行相关的布局。布局结束后要做出相关的逻辑设置，即打开页面时手机版本及颜色均为第一个选项，在选好版本颜色后还有以下的保障服务的额外勾选部分，最后在下方记录出总金额。注意事项:1. 在引入js文件时，要用
基本思路:
首先将小米商城的主页部分的导航区和底部区域部分写入此商品详情页内，并对此页面内大致分成3个大的div组成，第一部分是内容区导航部分，之后将下面整个大的内容区域左边放入轮播图，右边进行相关的布局。布局结束后要做出相关的逻辑设置，即打开页面时手机版本及颜色均为第一个选项，在选好版本颜色后还有以下的保障服务的额外勾选部分，最后在下方记录出总金额。
注意事项:
1. 在引入js文件时，要用<script src=""></script>的方式引入，不能用link的方式引入，之前因为引入js路径不对，找这个问题找了很久，还是要多注意这方面的问题；
2. 在设置此页面的相关逻辑时，可以用jQuery做相关设置；
3. 在选中小米提供的保障服务时，要用indexOf() 方法，这样可以可返回某个指定的字符串值在字符串中首次出现的位置，这样可以找到checked字段以便做出相关设置；若要除移选中框时，可以使用replace属性，在之后的设置方法为('checked','')，后方是一个空引号；
4. 值得注意的是，在计算总值时，jQuery获取值需用双引号；用getAttribute返回内部的一个属性值，将其乘以1即可得出相关价钱。
