基于Vue实现人民币小写转为大写功能

// 在main.js中定义过滤器
Vue.filter('convertToChinese', function(value) {
  // 转换逻辑同上
});

// 在模板中使用过滤器
<p>大写金额: {{ amount | convertToChinese }}</p>

// currencyConvertPlugin.js
export default {
  install(Vue) {
    Vue.prototype.$convertToChinese = function(value) {
      // 转换逻辑
    };
  }
};

// 在main.js中使用插件
import CurrencyConvertPlugin from './currencyConvertPlugin';
Vue.use(CurrencyConvertPlugin);

// 在组件中使用
<p>大写金额: {{ $convertToChinese(amount) }}</p>

// vue.config.js
module.exports = {
  chainWebpack: config => {
    // 配置Webpack插件处理金额转换
  }
};
