<body>
    <div id="app">{{name}}
        <el-button type="primary" @click="testMethod()">测试</el-button>
    </div>
    
   
    <script>
       const { createApp, reactive, toRefs } = Vue;
       const vue3Composition = {
           setup(){
               const data = reactive({
                   name: '张三',
                   age : 24
               })

               const testMethod = () => {
                   console.log('hello -----',data.name);
               }

               const dataRef = toRefs(data);

               return {
                   ...dataRef,
                   testMethod
               }
           }
           
       }
       const app = createApp(vue3Composition).use(ElementPlus).mount('#app');
    </script>
</body>
</html>
