}const name = ref<string>('');
const phone = ref<string>('');
const message = ref<string>('');
const messages = ref<Message[]>([]);const submitMessage = () => {if (name.value && phone.value && message.value) {const phoneRegex = /^1[0123456789]\d{9}$/;if (!phoneRegex.test(phone.value)) {alert('请输入正确的手机号！');return;}messages.value.unshift({name: name.value,phone: phone.value,message: message.value});name.value = '';phone.value = '';message.value = '';} else {alert('请填写完整的信息！');}
};const deleteMessage = (index: number) => {messages.value.splice(index, 1);
};const editMessage = (index: number) => {const editedMessage = prompt('请输入编辑后的留言内容：', messages.value[index].message);if (editedMessage !== null) {messages.value[index].message = editedMessage;}
};
</script><template><div id="app"><h1>留言板</h1><div class="message-form"><label for="name">留言者姓名：</label><input type="text" v-model="name" placeholder="留言者姓名"><label for="phone">手机号：</label><input type="text" v-model="phone" placeholder="手机号"><label for="message">留言内容：</label><textarea v-model="message" placeholder="留言内容"></textarea><button @click="submitMessage">提交</button></div><div class="message-list" v-if="messages.length > 0"><div v-for="(msg, index) in messages" :key="index" class="message"><div>留言者姓名：{{ msg.name }}</div><div>手机号：{{ msg.phone }}</div><div>留言内容：{{ msg.message }}</div><button @click="deleteMessage(index)">删除</button><button @click="editMessage(index)">编辑</button></div></div></div>
