jsx里的事件是不是不能直接修改变量值,必须要写个方法,去修改值,我这样试了下好像不行
export default defineComponent({ setup() { const count = ref(1); return { count, }; }, render() { const { count } = this; return ( <button onClick={() => { count.value++; }} > {count} </button> ); }, });
vue3 响应式变量不能使用 ES6 解构,不然会丢失响应式。你直接this.count就没问题了

原来如此,我还以为只有reactive不能解构,明白了,非常感谢!😃
