input标签v-model属性失效

 问题：input标签v-model属性失效，清空ans, 但是ui上依然显示。 html和js代码

<input @input="onInputChange" class="ans" v-model="ans" auto-focus><input>

	const onInputChange = () => {if (ans.value === ques.value) {endTime = Date.now();ans.value = ""; // 清空了值，但是ui上依然显示typemasterCharp[ques.value]ques.value = "A";startTime = Date.now();}};

 解决方案： 使用nextTike, 注意要import

<script setup>import {ref,computed,onMounted,onUnmounted,nextTick} from "vue";const onInputChange = () => {if (ans.value === ques.value) {endTime = Date.now();nextTick(() => {ans.value = ""; // 再次确保 UI 更新console.log("已清空");});typemasterCharp[ques.value]ques.value = "A";startTime = Date.now();}};
<script>

疑惑： 很奇怪的一点是，nextTick()前边再加一句ans.value=""就又失效了，真离谱，如下

	const onInputChange = () => {if (ans.value === ques.value) {endTime = Date.now();// console.log(endTime - startTime);// console.log(ans.value);ans.value = "";nextTick(() => {ans.value = ""; // 再次确保 UI 更新console.log("已清空");});// console.log("已清空");// console.log(ans.value);typemasterCharp[ques.value]ques.value = "A";startTime = Date.now();}};
