vue大小写转换指令（使用Vue开发一个大写人民币转换器）

朋友是做财务的             ，由于工作时间不长
 
  
 
  
 
  
 
  
 
  
 
  
，每次将数字转为大写人民币的时候











，总是提心吊胆的  
  
  
  
  
  
 ，生怕弄错了 
  
  
  
  
  
 。而且 
  
  
  
  
  
 ，如果是整数的话


 


 


 


 


 


 
，还好 
 
 
 
 
 
，但是有小数的时候就比较费劲了  
   
   
   
   
   
  ，比如123.45

 

 

 

 

 

 
，转成大写应该是壹佰贰拾叁元肆角伍分 
  
  
  
  
  
  。然后就找到我
 

 

 

 

 

 
，问我有没有什么办法？

简单啊             ，做一个转换程序不就可以了嘛？而且网上现成的一大把

 


 


 


 


 


 

。出于好玩
 

 
 

 
 

 
 

 
 

 
 

 
，所以使用Vue做了一个人民币大写转换器











，在https的支持下                   ，可以使用复制
 
 
 
 
 
 
 
 
 
 
 
 
，朗读功能 
 
 
 
 
 
。还贴心的做了一个大写人民币参照表 
   
   
   
   
   
   。

先看一眼成品

下面说说代码

















，及其简单哦！

创建一个Vue工程             ，在main.js中引入ant design import App from ./App.vue import Antd from ant-design-vue import ant-design-vue/dist/antd.less Vue.use(Antd)

直接再App.vue上完成吧
 

 

 

 

 

 
。
