先上图：
界面内容有轮播图、商品信息、评论、商品详情，点击选择规格浮现弹窗。
这里为了开发起来方便，只给第二个按钮附上了bindtap。
在app.json中先配置该页面，不必多说。 "pages/detail/detail"
js
// pages/detail/detail.js
Page({
/**

这里注意一点，url为什么那么一大串？因为微信小程序不支持本地图片，如果是网上图片直接放路径即可，但是是本地图片的话它会报这样的错：
xxxx.wxss 中的本地资源图片无法通过 WXSS 获取，可以使用网络图片，或者 base64，或者使用
它提出来了三种解决办法：1网络图片；2将图片转码为base64；3使用imgae标签 src属性。
而方法2将背景图片使用编码base64进行转换，可以在这个网址进行http://tool.css-js.com/base64.html 转换，如：background-image: url("转换后得到的编码文本")，如果多次使用的话可以将该值设置为全局变量，再在js文件进行引用即可。
