税务计算器/微信小程序开发

2019年1月1日即将到来，码农不仅关心自己的技能，还关心自己能否拿到更多的工资。每次计算都要通过百度查个人所得税，但是很多都是老的税率计算，找新的还是比较麻烦，所以我开发了一个最新税率的小程序。解决和我一样痛苦的代码农民的问题。根据最新税制改革计算个人所得税的计算器。目前支持南京，以后开放杭州、上海、北京等城市。有疑问可以加底层开发者微信。

首先在微信官网下载微信小程序开发工具https://mp.weixin.qq.com，在https://mp.weixin.qq.com注册小程序账号，完成个人实名认证。在小程序的后台获取appid，然后就可以开发了。示例查看二维码：

只需使用weui小程序ui框架进行页面布局。

把计算好的结果放在result对象中 通过wx.setStorage放在缓存中，传到下一个页面。最后展示出来。
