代码

html 复制代码

<view class="commentBox" :style="'bottom:'+KeyboardHeight+'px;'">
	<textarea placeholder="请输入评论" v-model="pingLun" confirmType="return" maxlength="-1" auto-height
		:focus="focus" @blur="onBlur" cursor-spacing="15" :adjust-position="false" class="area" :fixed="true" />
	<button :class="{'sendBtn':true,'greyColor':!pingLun}" :disabled="!pingLun">发送</button>
</view>

<!-- 评论按钮 -->
<view class="funcBtn pinglun" @click="onfocus">
	<image src="/static/images/circle/comment.png" mode="aspectFill"></image>评论
</view>

javascript 复制代码

const pingLun = ref('') //输入评论内容
const focus = ref(false) //默认不聚焦
const KeyboardHeight = ref('') //键盘高度
onReady(() => {
	uni.onKeyboardHeightChange(res => {
		KeyboardHeight.value = res.height;
	})
})
onLoad((options) => {
	// 如果来自于评论
	if (options.fromType == 'comment') {
		focus.value = true
	}
})
// 评论聚焦
function onfocus() {
	throttle(() => {
		focus.value = true
	})
}
// 失焦
function onBlur(){
	focus.value = false
}
