[图片] 我想要实现的是进入页面后点击表情（emoji.png)按钮可以弹出表情选择框发送表情，再次点击可以关闭表情选择框，该功能在浏览器上能预期实现，但是在微信小程序上则是：一进入页面就打开了表情选择框，再次点击也无法关闭，检查过代码，应该没有问题，这是什么原因？ <template> <scroll-view scroll-y="true" class="container"> <!-- 聊天列表 --> <view class="chat-body"> <view v-for="(item, index) in chatList" :key="index"> <view class="chat-one" v-if="!item.isMe"> <image class="chat-face" src="@/static/faces/1.png" /> <view class="chat-box"> <view class="chat-sender">安若熙</view> <view class="chat-content" v-if="item.type === 'txt'">{{ item.content }}</view> <image class="chat-img" v-if="item.type === 'img'" :src="item.content" mode="widthFix" /> </view> </view> <view v-else class="chat-one chat-one-mine"> <view class="chat-box"> <view class="chat-content" v-if="item.type === 'txt'">{{ item.content }}</view> <image class="chat-img" v-if="item.type === 'img'" :src="item.content" mode="widthFix" /> </view> <image class="chat-face" src="@/static/faces/2.jpeg" /> </view> </view> </view> <!-- 聊天输入 --> <view class="chat-footer"> <input class="msg-input" type="text" cursor-spacing="16" v-model="myInput" placeholder="不能发送空白信息 " /> <image class="img-chose" src="@/static/imgchoose.png" @click="chooseImgAndSend" /> <image class="emoji-icon" src="@/static/emoji.png" @click="toggleEmojiPopup" /> <view class="send-btn" @click="sendMsg">发送</view> </view> <!-- 表情弹出窗口 --> <view class="emoji-popup" v-show="showEmojiPopup">     <image         v-for="(emoji, index) in emojiList"         :key="index"         class="emoji-img"         :src="emoji"         @click="sendEmoji(emoji)"     /> </view> </scroll-view> </template> <script> export default { data() { return { chatList: [ { isMe: false, type: 'txt', content: '今晚吃什么？' }, { isMe: true, type: 'img', content: '/static/imgs/2.jpeg' }, { isMe: false, type: 'img', content: '/static/imgs/3.png' }, { isMe: true, type: 'txt', content: '哇，小姐姐好美啊！' } ], myInput: "", showEmojiPopup: false, emojiList: [             '/static/emojis/happy.png',             '/static/emojis/sad.png',             '/static/emojis/angry.png',             '/static/emojis/laugh.png', '/static/emojis/laugh tears.png'         ] };
